Communications

Network Neutrality is the wrong fight!

Winning would mean giving up much more important rights – historical rights that were in place in the US as recently as 1995 and remain in place in most of Europe even today. 

We shouldn’t settle for network neutrality. It’s a poor substitute for what we had and much less than what we need. Let me explain. There are two topics to discuss. The first is “common carriage,” a centuries old legal concept that applied to the US telecom industry throughout most of the 20th century. The second involves communications protocols. Both topics are complex, so I will cover only what’s needed to understand why we shouldn’t accept network neutrality and why, at a minimum, we should fight for enforcement of existing common carriage rules. 

Network neutrality is about allowing any Internet application to run over an Internet connection, i.e. over a connection that uses Internet Protocol (IP). But under common carriage as it applied prior to the late 1990s, we had a more powerful right – the right to run any kind of network protocol, IP or otherwise, over a lower, simpler service which today we call a “bit stream*.” Why does this matter? Because real innovation is also possible at these lower layers and that innovation continues to be important. But today, such lower layer innovation is restricted to inside one building or one campus. Yes, we can tunnel some lower level innovations over IP, but not all of them and only at a cost. 

IP telephony (VoIP) is one place where problems arise. Most enterprises use IP PBXs internally, yet calls between enterprises use the PSTN. Many companies have attempted to address this gap, but progress is slow and expensive. Within an enterprise, IP telephony packets are given priority, but that priority is not supported on Internet access links and network neutrality doesn’t help. As a result, to interconnect VoIP calls, enterprises must lease separate dedicated access circuits – circuits usually based on bit stream access – to support “SIP trunks.” Up until the late 1990s, these circuits were regulated under common carriage. Today they are an unregulated monopoly, with prices derived from the cost of voice circuits 15-20 years ago, i.e. abnormally expensive for today. 

 Common carriage is the legal concept that, in exchange for government granted monopoly access to rights-of-way, the monopolist must carry anyone’s traffic over the resulting infrastructure, at regulated rates. For centuries this has applied, to canals, to roads, to railroads, to telegraph lines and, until nearly the end of the 20th century, to telecommunications lines. But during the legal battles after the Telecom Act of 1996, the FCC basically gave up on common carriage.

If we accept Network Neutrality instead of common carriage, we guarantee future innovations happen only above the IP layer. Innovation at lower layers will be restricted to enterprise or campus applications. That’s too bad as it was the existence of common carriage that allowed the Internet to develop in the first place. Do we want to eliminate that kind of innovation in the future? 

If anything, we should be fighting to extend the ideas of common carriage to lower layers, e.g. dark fiber. Installing dark fiber is expensive and requires access to rights-of-way that are limited. The installed fiber is capital expensive infrastructure that lasts for decades. Such conditions justify granting monopoly access, in exchange for common carriage and regulated rates of return. But when you light up a dark fiber, you use (relatively) low cost gear with a short life (even if it can survive for ten years, Moore’s Law renders it functionally obsolete within 2-3 years). What's more, there’s rapid innovation in opto-electronics gear. Just look at the order of magnitude difference in cost between enterprise and carrier fiber-optic gear. 

Today, the US is loosing leadership in all things Internet. Network Neutrality will just put a nail in our coffin. To stop our decline, fight for restoration of the common carriage principals that existed through most of the 20th century and still exist in law. To regain world leadership, fight to extent those principals to include access to dark fiber at regulated rates.

---------------------------------------------------------------------------------------

* Bit stream access.   In the 20th century two regulated services provided what the 21st century calls bit stream access. These were voice telephony and T1 circuits. T1 circuits directly carry a stream of digital bits. Modems allowed voice connections to carry digital bits, for example, for bulletin board services and other purposes long before the Internet became popular.

Ben West's coverage of ISCWN

While at the ISCWN in Vienna, I met Ben West of WasabiNet in St. Louis. He’s provided excellent coverage of the sessions he attended in his day-by-day posts here:

Day 1;  

Day 2;  

Day 3.

My notes from the Community Wireless Networks Summit in Vienna

As with most conferences I attend, I took most of my notes using Twitter.  Since I can't always depend on accessing old tweets, here is the entire tweet stream from the conference in one blog post.  I don't know if this is of use to anyone else, but at least I know I'll have a record of my notes that I can refer back to.

The full name of the conference was The International Summit for Community Wireless Networks (ISCWN) and it was held in Vienna on August 12-15, 2010.  See the conference website.

International Summit for Community Wireless Networks http://bit.ly/9Lp41p
Good conference Wi-Fi http://bit.ly/dkwUh2
OK, I'm finally set up to Tweet &/or blog the International Summit for Community Wireless Networks http://wirelesssummit.org
While there's plenty of broadband behind the Wi-Fi, there are very few power outlets, at least as yet.
Community Wireless conf finally getting underway
Sascha Meinwrath opening: 1/2 the participants are missing, even some who were here an hour ago, so expect stragglers, but we start.
Sascha: 80% of cash raised goes to travel allowances; 10% everything else; plus donations.
Aaron Kaplan, Funkfeuer, on TechGate facility science park estbsh'd 2001 by City; conf venue; also supports Funkfeuer
Aaron there is swimming in the old Danube - it's clean now! Also boat rental nearby!
Aaron: Funkfeuer hotspots since 2003, now reaching almost to Bratislava. Mixed mesh and P2P backbone
Sascha on previous feedback - social time is key
Jim Baller: America at the Crossroads: Greatness or Mediocrity. 15+ yrs fighting ILECs on behalf of muni's - mostly successful!
Baller: credits Broadband Coalition http://bb4us.net/  Also as key to Congress requiring FCC to do a BB Plan
Baller on the US national BB plan: We need big goals, the BB plan didn't deliver! It's goals for 2020 happening elsewhere today.
Baller: US BB Plan focuses on inches, not yards and miles.
Baller: US BB Stimulus: Awards coming quickly (9/2010 deadline): middle mile, rural first mile
Baller on Google gigabit initiative yielded 1100 muni applications and showed pent up demand
Baller: Ugly side - incumbents bigger, stronger & nastier than five yrs ago. Cable industry even nastier. Now Google is in question.
Baller: But btwn BB Plan (it's a plan), Google fiber init., $7B Stimulus goes to new parties, community BB efforts
Baller responding to Q about wireless: I'm a fiber guy, then disappointing comments on FCC being pro-wireless. Misses FCC focus :(
Baller responding to Q about Australia admits that most in US don't know what's happening in the rest of the world.  US always has excuses - "we're different."
Sascha introducing Ramon Roca, President, guifi.net Foundation, a fantastic alternative that's happening in Spain. 
Guifi runs a very large network across rural (and urban) Catalonia in Spain. http://guifi.net/
Ramon Roca: Vision for the Future. Will talk about: Why scale? and their sustainable economic model!
Ramon: Guifi has 10K+ nodes and 15 Km of networks, but still tiny compared to telco. Scale as a goal. Need growth to be sustainable.
Ramon: need sustainable model - critical mass; org issues; legal; partners. Non-profit core w/biz around.
Ramon: Demand is there; also incumbent not interested in low 40%.
Ramon on mgmt: horizontal, bi-directional & collaborative - examples from their website. Website appears to be key for communit.
Ramon on public/private: public requirements must be written: contracts, license, P2P agreements. Must be clear, and legal.
Ramon on public/private - like OS licenses, the network is considered private by govnmt. Need documents just as open src does.
Ramon facilitates integration and cooperation between diverse groups, e.g. need churches for their steeples! need public ROW access.
Ramon: Guifi license is required if you want to participate! Like GNU license, Guifi license even deals with revisions.
Ramon: Guifi license defines everything
Ramon: Guifi is also a ""public"" network in the legal sense in Spain because they had to in order to deploy some fiber.
Ramon: Guifi ROI for many: supply chain dlrs/shops, prof svcs and svc provdrs who mediate wholesale mkts.
Ramon: Catalonia is a bit ahead of Spain but w/o Guifi Osona (rural Catalonia) way behind. Now Osona ahead of rest of Spain & even the UK.
Ramon: Guifi network now 15% of BB links in Osona; and yet DSL subscription haven't dropped.
An English version of the Guifi Wireless commons license is here: http://guifi.net/WCL_EN
Ramon futures: working on fiber from farms (FFtF) cheap & easy & Gbps; always a combination.
Ramon has had fights with incumbent about ROW (even when on private property) and about access to poles. Ramon - do it! then fight.
Ramon - their main focus is to stay on private ROW, but as a public carrier they can now go after public ROW.
Ramon: stories about fights over public fiber & public ROW - everything you expect, except Guifi seems to win, espc. in rural area.
Ramon: Guifi participants getting access to public fibers laid for cameras after threaten authorities - tractor might hit camera...
Ramon concludes by emphasizing need to enlist service businesses and computer shops, e.g. 3rd party for profit businesses.
Lightning talks where individuals describe their networks.
Austin (TX) Wireless - hotspot service; wanted free Wi-Fi; customers incl coffee shops that compete with Starbucks.
Austin Wireless - other things to help venues, e.g. splash pages
Austin Wireless: splash pages useless if not totally relevant for the customer: Weather, sports, local info, Facebook links, venue.
Austin Wireless: Now making $ by providing marketing services to their venues, restaurants, coffee shops, etc.
Austin Wireless: Also does Chimpit which brings venue portal even if you're on another network.
Chambana.net joint project of IMC and Acorn IT collaborative - ~6 active people and 9 servers. Walk-in computers, media prod. lab.
Chambana.net host websites, many other IT services, but also some wireless! Small network, switching from NetBSD to OpenWRT.
Chambana.net: It sounds like their wireless net is secondary to what they do, and is currently down and being reworked.
Chambana.net: Wireless network is completely open, no splash page. Runs on donated hardware
Chambana.net runs on donations, but entire uplink is one Comcast business service. But part of a stimulus grant, so near future good
Tribal Digital Village: 19 tribes HQ in San Diego CA, only way to get Internet to reservations. sovereign nations within US, but...
Tribal Digital Village: 350 miles of P2P and P2MP links mostly license exempt; 18 bldgs
Tribal: Paid NW in parallel reaches 200 individual homes. 2/2 Mbps for $34.95 per month. Hope to reach 2000 of 2700 homes.
Tribal: 1K devices connected to net. Fiber at headend feeds an arc of P2P links. Now many gamers accessing via local centers.
Tribal: Too small and separate to think about running their own radio regulatory regimes. But not too worried about conforming :)
Djursland http://www.diirwb.net/ Rural area in Denmark; 95% can get DSL (fr 1600 exchgs). Last 5% not svc'd.
Djursland P2MP design
Djursland: NW built by volunteers
Djursland gets favorable Interent transit because the farmers drove (& control) the fiber backbone deployment.
Funkfeuer: mesh using OSLR; got help from jaap@scii.nl & friends in Berlin.
Funkfeuer: 240 roofs; financial sustainability based on hosting center revenues; Gbps uplink
Funkfeuer: slightly below mkt for hosting; TV streaming experiments; running Wi-Fi for events.
Funkfeuer: Fiber splicing is easy, if you have the expensive machine (~6000 Euros). Basically welding glass.
Funkfeuer is a closed user group. This is important for VoIP and other regulatory issues, including streaming TV to you members!
Funkfeuer Graz: like NW in Vienna; Technical Univ in Graz helped them grow fast; slower growth >2007 as 3G faster.
Funkfeuer Graz: now working to link with Bratislava (Slovokia) which could be the first international community network in EU.
Funkfeuer Graz: longest link today is 30 km which gets them 1/2 way to Bratislava (Ubiquiti radios)
Malcolm Matson knows of two networks connected (quietly) btwn Solovakia and Hungary.
Belgrade Wireless: up to 20 km links (> 50 Mbps) using corner antennas as shown in previous conf. NW now extends over 100 Km.
Belgrade: 3D corner antennas invented by Prof in Belgrade. Big focus on community events.
Belgrade: 3D Corner Antennas http://su.pr/AjXm1p - feeder for dish reflector - mixed polarization
More 3D corner antenna info here  http://su.pr/7t9990 Need to follow up on whether this remains relevant w/ MIMO using polarization.
Updates from the OLSR-NG Project - Henning Rogge (FKIE) & Aaron Kaplan (Funkfeuer.at) - history, today & futures.
OLSR-NG: 1 of 2 major mesh stds (other AODV). RFC 3626. Tonnesen PhD, Lopatic LQ & Fisheye extensions
OLSR-NG working on OLSR. Guys in Berlin starting over (BATMAN); HSLS hazy sighted link state (CUWin).
OLSR-NG session: CUWin HSLS didn't get beyond simulations
OLSR-NG: OLSR is link state - every node knows whole graph (100K entries = 4.8 MB); but MPR now off
OLSR-NG: MPRs only matter with really dense NWs, but with only 2-3 links per node, they don't pay.
OLSR-NG: ETX link quality metric used instead of basic hop count, i.e. sum of ETXs not sum of hops. But heavy compute load!
OLSR-NG bringing down compute load (now linear not exponential). 100-to-1 benefit with 400 nodes. Still Dijkstra, but optimize data.
OLSR-NG: malloc() thrashing fixed
OLSR-NG futures: soft refresh (CSN), better metrics (ETT, MIC), multipath routing (experimental), Q of layer 2 capabilities.
OLSR-NG: Henning comments on how few multi-path routing projects have made any progress... Problem: must choose whole path. very hrd
OLSR Henning: OLSRd 0.6.0 is current. Clean rewrite of routing code; smarter gateways to reduce thrashing btwn GWs.
Henning: 0.6.0 has very few (& only site-specific) bugs - very stable!
Henning on future plans: telnet/http server (done); config mgmt (stability, flexiblty.
Henning also thinking about better metrics but limited by packet format prior to OSLR v2. Many metrics in discussion in academia.
Henning responding to Q: negative about dual protocol mode to support migrations. Thinks it wold be very hard.
Henning - active developers= ~1.5 people
Henning complaining about academics who've made patches w/o consulting (thus doing stupid things) and without plans to give back.
Henning & Aaron on how plugin system makes it easy to try new things in a clean fashion.
Freifunk Berlin started 2002; then OSLR in 2003-04; 28 devices @ 2004 OS conf; PC to openWRT for embedded.
Freifunk took off in 2005 despite labeling website ""OSLR experiment"" but users wanted reliability
Freifunk can't even switch to B.A.T.M.A.N. because OSLR widely deployed
Freifunk net is now shrinking, as people who came only for bandwidth are getting DSL and 3G mobile.
Freifunk has issue of switching gateways which doesn't affect Frunkfeuer with their fixed gateways and public IPs.
guifi.net is a bunch of communities, not all interconnected. 10,300 nodes using same software, same tools and same license.
guifi.net is showing off an impressive set of tools for examining nodes, plus there's extra data that the node owner can access.
guifi.net Using MRTG http://oss.oetiker.ch/mrtg/
guifi.net is a large wireless LAN. Must search for & connect to services, like Internet access. Libraries & other offer Inet-GWs.
Île sans fil network in Montreal  http://www.ilesansfil.org/  Now 200 hotspots installed, free Internet thru portal page.
Île sans fil limits users to 7 GB/wk. 150K users registered. Each hotspot has own page. Projects: Authpuppy, WiFiDog
Wireless Toronto - captive Wi-Fi portals, started with Wifidog from ◊le sans fil.
Wireless Toronto has struggled compared to Montreal. All volunteers. Hotspots, but now adding mesh, e.g. in parks.
Wireless Toronto - no spt fr Government who started and sold a parallel NW. Hard to find location-based content for portal pages.
Wireless Toronto survives on annual fees from businesses with portals; organized as a club, not a nonprft
Wireless Toronto new mesh started with BATMAN but found OSLR more reliable. Using Open-mesh but moving to Authpuppy.
Wireless Toronto - the less you talk about Wi-Fi and the more you talk about mktg, the better you do selling business hotspots.
Wireless Toronto using AutoAP in part to just monitor what's going on, wirelessly, in their neighborhoods.
Open Wireless Networks http://consume.net in London
Consume fell out of use ~2003
OWN: nodes all clustered in London near Greenwich Park. Not 400 nodes
Good line-of-sight planning tool:  http://www.heywhatsthat.com/
Village Telco http://www.villagetelco.org/about/mobiles have brought telecom to Africa, but not Internet, yet...
Village Telco: it didn't take off
Village Telco: Built ""mesh potato"" - solar mesh device w/analog phone adapter; production units next month.
Village Telco: Mozilla is filming the project.
Village Telco: Retail cost $119
Wlan Ljubljana: http://wlan-lj.net Can't beat widespread fiber at $14/month, but each has excess capacity and willing to share.
Wlan Lj now up to 50 nodes & adding rural areas - now wlanslovenija! http://wlan-si.net entirely volunteers
Wlan Lj is clearly a group of hackers having fun, but it's not clear to me if they are really serving a need. Sustainability???
Wlan Lj has done solar nodes - 24 hr reliability but froze during the winter and wasn't restored until spring (cold on roof!).
Athen Wireless Metropolitan Network (AWMN) strtd 2002 because no DSL; open experimentat WLAN.
AWMN has some people who offer Internet access, but it's not the primary goal. Participants tend to be Univ types - young, educated.
AWMN mostly at 5.4 GHz with Linux and MikroTik routers. Islands of OSLR connected by BGP; 2505 nodes; 1100 backbone nodes.
AWMN speeds vary 11 Mbps to 150 Mbps. 730 access points. Organized by an association; events; community; no grants.
AWMN Recently, large deployments of 11n
AWMN As a local LAN, they have mirrors of many Internet services, also transliterated version of Google (Woogle), Yahoo, etc.
Richard MacKinnon of Austin Wireless follows me in the Freemium session. AW strt'd as all free, but wasn't sustainable.
MacKinnon: Austin Wireless used automation to replace 50 volunteers with 2 fulltime staff. Merchants pay to provide free access.
MacKinnon: Pull together local news for hotspot portal pages
MacKinnon: Used to charge $5/mo
MacKinnon: Integrate Facebook into portals, incent patron's to talk about the business they're visiting on their FB page. Biz value!
MacKinnon: installations were fun at 1st
MacKinnon: $55/mo buys support. Restaurants hate Wi-Fi but have to have it to be competitive. So support is key - ""power cycle box!
MacKinnon: deals with cable company; POS crdit crd installers.
MacKinnon: Ads didn't work but local ads may be coming back.
Nemanja Topovic, Belgrade Wireless, Serbia started as all volunteers. Had problems with Government (spectrum laws).
Topovic low cost svc didn't work (1 Euro/mo) as people expect full svc. Discusses many paths they've tried, unsuccessfully...
Topovic - network grew rapidly 2004-2006 but growth has stopped. Looking for a program that could restart their network.
Topovic: BGWireless not a mesh, uses high speed P2P and P2MP. Closed network.
MacKinnon suggests his biz mode for Topovic. Key is offering free svc to avoid spt issues and then find a premium svc to cover costs
MacKinnon - important to offer new paid service as something new, not as a price increase on old service.
MacKinnon: 200 customers today (and 1 & 2 yrs ago) but different group & paying more & more loyal. Free customers were least loyal.
MacKinnon user community divided: some just want Internet
Paul from NFP? talking about SW defined GNU radio work going on in the building. Available for discussions later...
Robin Chase, Meadow Networks (previously founder of Zipcar) will be evening keynote spkr - next up.
Robin Chase on tie-in of transportation and networks: financing (fuel tax moving to road tax eventually - per km!).
Chase Auto density in cities (congestion) but expense of rural rds. Moving to congestion pricing. Will need more technology...
Chase on transport costs not reflecting true costs (fuel/environment, etc.)
Chase Public-Private Partnership discussions are missing the individual. Transport tech has decided they need their own stuff.
Chase: transportation guy gets his spectrum; EMS/medical types need their own stuff- it's just comms
Chase: Transport problems: Lumpy density, congestion, financing, right pricing same problems as in comms infrastructure -> dist. NW
Chase: future for transport and comms is distributed networks
Chase focus on distributed and collaborative inputs as a path to innovation.
Chase: words to use when talking about Gov. spending: open data; open standards; open source
Chase talking about Comuto (ride sharing in France)  http://www.comuto.fr/ now has more unique users than ZipCar (& just in France).
Chase: talking about CouchSurfing: 7 yrs old; 200 countries, 71K cities; more ""beds"" than major hotel chains.
Chase on Chatroulette - built it in 3 days; but in 6 months it now gets 30M unique visitors - mindboggling!
Chase: Andrey could do ChatRoulette because platform (Pcs, Internet) was there and there was excess capacity available.
Chase on all the crazy ideas that are now iPhone apps and yet the excess capacity has fostered some incredible innovations.
Chase: People & Platforms -> Speed & Scale
Chase wants open mesh device in every car that will have to be paying congestion fees, getting traffic data
Chase wants an open platform in cars so we foster new apps we can't can't even envision now.
Chase: what if all nodes (smart grid, smart cars, smart infrastructure) were peers? and open platforms!
Chase: www.networkmusings.blogspot.com & @rmchase & rchase@alum.mit.edu
Vic Hayes of TU Delft University: Spectrum Assessment for Wi-Fi. History of FCC & license exempt spectrum and Wi-Fi market.
Hayes: FCC landmark decision 1985- license exempt; use more spectrum than required; spread spectrum tech.
Hayes: Standard CDMA history including Hedy Lamar's patent, but I learned something new - she was born in Vienna!
Hayes has some good slides to explain CDMA. I'll probably stick with my standard slides http://su.pr/1LMCYl
Hayes: FCC wanted to allow spread spectrum over wider bands but got objections so they settled on ISM because no one cared.
Hayes on attempts to get similar rules thru CEPT - succeeded in 1991 for 2.4 GHz band only and with slightly different rules.
Hayes: CEPT said only -10 dBW ERP (100 mw) and 10 mw per MHz
Hayes: because of cost of electronics, 900 MHz took off 1st (in 1989)
Hayes on how Wi-Fi 11 Mbps beat HomeRF even though the FCC permitted wideband hoppers (1998-2000). Wi-Fi faster
Hayes: 2002 FCC permits intelligent hoppers (reduce blutooth intf) & power spectral density rule (opens the way for OFDM, i.e. 11g).
Hayes: Now 5 GHz - FCC NII proceeding - Apple, Lucent, etc. release 1997. Adds 5 GHz spectrum.
Hayes: meanwhile CEPT yielded to Satellite industry and reduces pwr at 5 GHz, but add more spectrum for HIPERLANS (455 MHz).
Hayes: CEPT decides to go to WRC 2003 to make 5 GHz primary and global. US problem because NTIA refused. Took until Jan2003 to win.
Hayes: In June03 WRC 2003 allocates 455 MHz co-primary in 5 GHz band. Accepted in US & EU - still in flux in many countries.
Hayes: Once spectrum is allocated, it still must be defended (find reasons in style with current political agenda).
Hayes promoting his upcoming book: The Innovation Journey of Wi-Fi, Edited by Vic Hayes et al. to be published by Dec2010.
Clarification of 1st unlicensed spectrum was 1937 for baby monitors, etc.
Hayes: Questions about Ad Hoc mode
Rabi Karmacharya & Basanta Shrestha of OLE Nepal using wireless to deliver Internet connectivity to schools in Nepal
OLE Nepal: Initial focus (2006) was OLPC, but if you got PCs, there was still no Internet
OLE Nepal: Don't have to teach kids how to use computers - that comes naturally - but need to create content in local language.
OLE Nepal: Teachers have to be retrained, and need to realize the kids may know more about the PCs that they do.
OLE Nepal: Need network infrastructure, in schools and between schools and the Internet.
OLE Nepal: Open source, open content
OLE Nepal: 28 people on staff
OLE Nepal: First priority is a network to and btwn schools as Internet upstream is very expensive in Nepal.
OLE Nepal: One highway with fiber runs length of country in the southern lowlands (near India border). Northern areas to 8K meters!
OLE Nepal: fiber line is connected to India so Internet transit pricing has come down substantially, but still very expensive.
OLE Nepal: approaching 38 schools in six districts & 4K students connected. P2P WLAN w/ typ. 5-10 Km distances
OLE Nepal: ADSL where available, used with VLAN.
OLE Nepal: On the plains, need to find a hill to act as relay point. Sometimes >20 km links needed (example 26km).
OLE Nepal: In hilly areas, may need 3-4 relay points at remote sites (4 hr walk)
OLE Nepal: School NW have: radio; switch; & 2-3 Wi-Fi Aps; all w/UPS. Select equip. for low power! Linksys WRT54GL w/DDWRT.
OLE Nepal: MikroTik 433 AH & 411 CPE - have used this up to 26 km. Also EnGenius radios, but not reliable.
OLE Nepal: SW tools: Google Earth, Radio Mobile, mirror tst'g. Use trees as towers (cut away foliage).
Ben West of Wasabi Networks (St. Louis) has posted his Community Wireless Day 1 notes here:http://su.pr/3FG39a
Ben West's Day 2 notes include notes from the session I spoke in: http://su.pr/1DHUFi
There's a big EU network that's not here. It's Czech Freenet: http://su.pr/2qMyeE 
Whoops - and this Czech Freenet: http://su.pr/24yYU8
Future for Community Wireless Networks session lead by Aaron Kaplan and Vic Hayes. EU wired net getting better and CWN shrinking...
Future of CWN: ideas fr. grp: underserved rural areas; hacker grps want to stay that way.
CWN futures: my categories: hacker comm, social comm & svc provider. All NWs have some of each, but one tends to be primary.
CWN futures: several people object to categorizations (in general?)
CWN futures: Movement to integrate node databases fr. many diff. networks. Exchange knowledge on making node db's. Mtg in <6 mo.
CWN futures: A world node database would create a larger vision of the movement, espc. for members in individual networks.
CWN futures: some desire for turnkey node solution prompts objection from Berlin hacker community that people would stop learning.
CWN futures: Ramon (guifi) sees evolution in the discussions over past 4 yrs: more consensus, meta focus (e.g. world db).
Networking rural areas: Rantanen - Tribal NW mostly done with grant money.
Networking rural areas: Rantanen offerring his cast off equipment to Krusevac Open
Networking rural areas: Krusevac network is technically illegal under Serbian law (ISPs must be licensed w/many problems & cost).
Telecom for disaster relief - Mark Summer of Inveneo talking about wireless in Haiti after the earthquake -http://www.inveneo.org/
Mark Summer: Mountain range around Port au Prince was key
Mark Summer: so many Sat Phones came into Haiti that satellite capacity was saturated.
Mark Summer: got Ubiquiti to get stuff from distributors (in 3 days)
Summer: Kitted everything over a weekend; VSAT vendor committed 5 Mbps link if dish fixed.
Summer: Google got very high res imagery on-line within 48 hrs and updated it every few days. Open Street Maps for former streets.
Summer: got VSAT up in <24hrs
Summer: Got 3-4 radios in per day
Summer: Linked 18 NGOs at 23 locations in 3 wks; NGOs didn't want it turned off, as better than pre-disaster.
Closing keynotes just starting. Tomorrow: open spectrum alliance
Aaron Kaplan thanking many, many. Node DB SIG being set up for this coming winter.
Sascha Meinrath asking for ideas we should ponder over next yr. Answers: 1. OS physical layer (GNU radio?) - seeking FPGA designers.
Answers 2) Allison Powell (@postdocal) learned we're still not good at telling stories. She's seeking people to interview.
Answers - Rabi Karmacharya (OLE Nepal) very struck by the discussions of biz models and how NW can help in disaster recovery.
Audience comments: worried that several major networks are loosing nodes
Audience comments: Session on splicing fiber was exciting. Community radio + community fiber (+ community satellite?) !
Audience comments: Credit to Matt Rentenen for offerring to pass on older equipment. Sascha suggests an email to CWN list.
Audience comments reinforcing idea of using Wikipedia as the master list of Comm Wireless NWs + spectrum laws http://su.pr/2C3YFz
At OSA Mtg http://su.pr/2AtH5O 1st formal mtg took 1.5 hrs as bylaws are in German & English. Hopefully we'll talk spectrum soon.
OSA Mtg: @postdocal asks OSA view on net neut & suggests links with other advocacy grps. Open a rathole? Sent for email discussion.
Now in GNU radio discussion. Ah techies, > interesting than policy talk.. Getting into to USRP http://www.ettus.com/ which I already know of.
Paul Fuxjaeger on GNU radio: OFDM for 11a, 11g required substantial mods to GNU radio blocks. Also hard meet IEEE timing req.
Fuxjaeger, GNU: For 2x2 MIMO, externally sync 2 USRP2s (not w/Ettus cable!) so as to maintain 2 Gig data streams, vs 1 w/Ettus cable
Fuxjaeger: http://www.oz9aec.net has interesting GNU radio stuff, also an update on Gumstix & GNU radio! More shortly...
Fuxjaeger: http://su.pr/A899kx has the pointers for Gumstix and GNU radio
Fuxjaeger: http://su.pr/1TZZeQ is the PR for Gumstix's product Stagecoach which packages TI OMAP processors that may be used w/Ettus
Kaplan wraps up the GNU radio session w/demo pasting macro blks & receiving signal from a Ham radio in 70cm band, i.e. 420-450 MHz.

Good conference Wi-Fi

Thanks ISWCN!

 

That's especially nice as it let me upload my photos from yesterday afternoon's stroll around Vienna -- all completed in a couple of minutes while waiting for the conference registration desk to get set up.

 

International Summit for Community Wireless Networks

I'm off to Vienna to attend a conference.  Conference info is here.  On Friday afternoon, I'll be leading a session in which I hope to get useful feedback on the "freemium" business model we're using for netBlazr.

Europe has a number of community wireless networks that have been very successful.  The networks in Vienna, Berlin, Athens and Catalonia stand out in my mind.  Of course, in the US we've had active legislation that's made it hard for governments to create community network.  But the EU networks mentioned above are member-based.  They may have benefitted from government funds at some point, but they formed independent of any government effort (at least as I currently understand things).  The other issue I've observed in a number of US community networks is a reliance on grants that aren't renewed and/or on enthusiasts who eventually leave to go to grad school or otherwise move on.  Something is different in the EU networks mentioned above.  Hopefully I'll better understand this by Sunday.  :)

As is my habit, I'll be taking notes in real time using Twitter (@brough).  After the conference, I'll gather those notes into a single page for a blog post.  This is primarily for my own benefit, as it's been an extremely useful way for me to take and save notes (assuming it's an event like the ISCWN where I want to keep notes!).

AT&T Wireless still struggling with the basics

Has AT&T gotten better since I last wrote about their network performance at some length?   Maybe not ...

 

Comcast: Use your bandwidth and we'll throttle you

Recently a friend decided to use an on-line service to backup his 750G raid array. He selected CrashPlan which, among other things, generates a projected completion time. With his existing DSL service it was going to take months, so he signed up for Comcast Internet with a plan that offered "up to" 10 Mbps down and 2 Mbps up. As he put it:

... when I was signing up for Comcast I specifically asked about high-volume on-line backup, and in particular whether it was Ok for me to buy the 2x10 service and run a heavy duty upstream job 24x7 at 1 mbit, and I was reassured that this was OK.

To see what happened, look at the "wan-out" statistics in gray above. Comcast came on-line in late March and CrashPlan was configured to use 1 Mbps of the "2 Mbps upstream" bandwidth. This worked for less than two weeks, then Comcast throttled the upstream to less than 600 Kbps.  Over the next six weeks, he was further squeezed to ~400 Kbps. Nothing in his house changed during this period, so the data above reflects Comcast's performance. As my friend puts it:

I guess what they meant was "... it's OK to try, since we can rate limit you ... to anything we want, you won't bother us by trying.  You won't get your bandwidth either, but that's not our problem. "

Comcast:  "Up to X Mbps," but only for occasional use.

Commercial use of TV White Spaces in 2 years?

One of the interesting discussions at the Wireless ISP Association meeting in St. Louis last week was around TV White Spaces.  Alex Goldman has a good summary from the WISPA point of view.  We also heard from Julius Knapp of the FCC during lunch on Thursday.

What's clear:

The FCC is going to act, in the 3rd quarter (before October 1st), on the 17 petitions for reconsideration that are pending.  While the details of their decisions will have to wait until their announcement, it's likely the final rules will allow viable commercial markets to develop.

At the same 3Q meeting they are going to adopt policies that allow multiple independent database managers to compete.  (There will be a mandatory coordination function).

My conclusions:

Once the final rules are determined, we'll see both Wi-Fi and WiMAX equipment release - in both cases by re-banding existing equipment and adapting existing antenna technology.  Over time, other products should emerge, but rebanding existing standards will happen first.  We should see products that WISPs can deploy within 2 years.

xG Technology at WISPA

xG Technology was exhibiting at the WISPA conference in St. Louis July 21-22, as they also did at the 4G Wireless Evolution conference in Miami in January.  In January, I visited their facilities in Fort Lauderdale and talked at length with their founder, Joe Bobier.  This is a company that, back in 2006, made some outrageous claims for a new kind of radio modulation.  At the time, some friends asked me to look into their claims.  I read their literature and their patent filings and concluded it couldn’t work as claimed without violating either the laws of physics or FCC regulations or both, and I wrote a blog post to that effect. Indeed my original conclusions appear to have been true. In 2006, they naively thought they could get the FCC to change specs for out-of-band signal levels.

What’s interesting is how they have completely reinvented their company. They have dropped the magic modulation ideas of 2006. Today, they are in alpha test with a mobile voice telephony system that uses conventional first order modulation.  I don’t know whether they will succeed in the market, but today’s product is at least built on credible technology, they are going after plausible customer sets, and what they’ve done is cute enough (from a techie point of view) to be worth some discussion.

Their system allows a service provider to delivery a cellular mobile voice service much like any other mobile voice service plus it can support optional data services at GPRS-like data rates.  The key difference is their system uses license-exempt spectrum in the 900 MHz band, thus avoiding big bucks for spectrum licenses.  They deal with interference from other users of the 900 MHz band by monitoring in both frequency and time and rapidly switching channels (up to 33 times/second) to avoid interfering signals.

Of course there are no standards for such a system so, while the RF technology is now very conventional, the base stations and handsets are proprietary.  They have adapted VoIP and SIP standards where possible, so their MSC is just a conventional 3rd party softswitch.  However, some of how they handle channel hopping, roaming and handoffs is inconsistent with IETF standards, so they have a SIP proxy and a DHCP proxy that together isolate their proprietary protocols (used over the air) from the rest of the system which use standard IP components and standard SIP.

I don’t know whether their business will work or not. Their current system delivers mobile voice telephony plus data at 2G speeds, but it doesn’t roam. It might be a good fixed line replacement providing city-wide cordless telephony, not unlike the PAS systems deployed in China, but with no need for spectrum licenses.  I wish them luck.

My notes from the WISPA conference in St Louis

The following is based on my Tweet stream (@brough) during the conference plus some other notes I took off-line during the Tower session (when there was no Wi-Fi).  

Brief summary:  The conference was a great success, certainly for me, but seemingly for all.

Notes from the Wireless ISP Association (WISPA) meeting
St. Louis, July 21-22, 2010

WISPA meeting scheduled to start @8:45am (20 min) but room near empty. Sleeping late in St. Louis? Conf Agenda, see http://su.pr/24Zlii near bottom.

Twitter's location service keeps telling me I'm in Berkeley CA when I'm in St. Louis. Having to reset it makes the svc less than helpful.

The 40 Mbps wireless link set up for this meeting died in last night's lightening storm. Hotel has DSL? ugh. Hope radio get fixed!

Rick Harnish speaking: WISPA has signed up ~50 new members just because people wanted to come to this meeting.

Nice to finally meet Matt Larsen after many years of seeing him on email lists. Matt comments that WISPA membership now over 400.

Steve Coran, Doug Karl, Dewayne Hendricks, Patrick Leary visionaries panel is up, but 1st the ""Did you know, shift happens"" video...

Dewayne H started as a ham (age 12, 1961), then 56kbps packet radio in 1986; went commercial 1990 - wireless Internet, mesh, early!

Doug Karl started in IT as OSU, needed Internet for off-campus folks and started P2MP wireless net.

Patrick Leary started in fiber but focus is broadband Internet and that led him into wireless (initially in Atlanta ex-urbs.

Doug Karl became advocate for WaveLAN (from NCR) radios and their use for P2MP, then an advocate for early WISPs.

Dewayne Hendricks - the gating issue is regulatory. Original NOI discussed open spectrum, no power limits! Today rules are tightening.

Doug Karl commenting on having your town put extra requirements on cable company when up for renewal.

Dewayne's mission impossible plan for spectrum - demo alternate spectrum approaches in other countries (e.g. Tonga); existence proof!

Dewayne: reinvent, repurpose mass-market stuff - Wi-Fi silicon, DOCSIS modems (use transverters!).

Dewayne is pessimistic about starting a new WISPA today. I have to have an argument with him!

Doug Karl: remember you are in the communications biz - wireless may be only part of that (don't be wireless only).

Now it’s hard to pick which of three tracks... Whitespace policy; 4G; or VoIPoW. Love policy issues, know 4G & VoIP but wish I had all PPTs.

Raja Gopal - Alvarion - pushing WiMAX. $5K for a 16e basestation today but admits in 2-4 years LTE will win. But deploy WiMAX now.

VoIPoW discussion justified by how much money can be made with voice, but need QoS and high level of service - must be dependable.

TV White space discussion: politics! politics! chg sensing requirements; still large antenna issue.

Marlon Schafer asks about eventual pollution of TVWS by home LAN devices. Jack Unger on current interference mitigation discussions.

another 3 tracks decision: Mktg; FCC's 3rd way regulation; or Fiber deployment. But the only Wi-Fi access in the Mktg room. :(

Mktg Elizabeth Bowles loves on-line but (on behalf of Forbes Mercy) pushing radio (PR & Ads) for rural WISPAs; also yard signs!

Mktg: Ken Janc, Lorex Inc, on targeted direct mail and door-to-door - expensive but can be cost effective (cost per acquisition).

Mktg: Ken Janc - at least have your installers do door hangers on next door houses when doing an install.

Elizabeth Bowles of Aristotle.Net on SEO, pay for advice if you are not found via ""broadband in <your location>"", get prof advice.

Elizabeth Bowles big proponent of video on your website - dramatically boosts response rates.

Elizabeth Bowles: mobile phone enable your website. Remember smart phones with Wi-Fi access. Unlimited mobile data is dead, so people using WiFi.

Elizabeth Bowles: need a Facebook Fan page! Twitter account; LinkedIn; YouTube, Flickr, Yelp, etc. Track and respond.

Elizabeth Bowles: Optimized press releases (select key words to get coverage) is to get on-line coverage, not local press.

Martha Huizenga of DC Access a WISP in small DC neighborhoods: pick targets; then: postcards, signs <cars, yards>, local newspapers.

Martha Huizenga postcards are the only printed media; leaves them at dry cleaners & other local stores. Rest are PDFs by email/online.

Elizabeth Bowles responding to a Q: Market Wire costs $400-$700 per release; so search optimization your release first!

Elizabeth Bowles answering Q: need 3-4 touches to get a response. Link sign, postcard, website landing page to drive touches.

Michael Calabrese of the New America Foundation is luncheon keynote - talk is focused on open spectrum and especially TVWS issues.

Michael Calabrese: big problem - Genachowski's focus on auctioning large parts of the TVWS.

Calabrese: FCC, Congress & WhiteHouse intent on auctioning everything, including 20 TV channels (after paying off TV broadcasters).

Calabrese: If 20 TV channels went, after repacking broadcasters, there wouldn't be enough TVWS for an equipment market to emerge.

Calabrese: Spectrum sharing still sailing under DC radar; he's pushing that TVWS database extend to additional bands (e.g. military?).

Calabrese: we should use the same database to allow temporary access to ""warehoused spectrum"" i.e. until spectrum holder uses it.

Calabrese: Why shouldn't WISPs have temporary access to any spectrum band that is not yet in use in their geography?

Calabrese: FCC is not nearly as aware of the WISP community as it should be. Pls visit them; write to congress; file ltr to NOI.

Network Management: Matt Larsen, Vistabeam with Butch Evans; Brian Vargyas, Baltic; Alex Phillips, HSLink; Cameron Crum, Wispmon.

Larsen favors open source. Issues: integrate related items, respect business (may have to fire specific customers), leverage tech.

Larsen on processes: Billing, Provisioning, Dispatch, NW Mgmt (core & customer), Support, CRM, CustSat, Mktg, Employee accountability.

Larsen: Vistabeam has 1700 miles of wireless backbone over 600 miles. Documentation is critical before someone goes out in the field.

Larsen: Billing Freeside, Powercode, Platypus, ... He uses Freeside.

Larsen: NMS - What's Up Gold, Nagios, Xymon; proactively call people whose service is down. Also RT for trouble tickets.

Larsen on phone system - uses Asterisk but also familiar with Tribox and others. Msg when there's an outage cuts support calls!

Larsen on documentation - uses Network View, Visio, Dude and a wiki to capture other things (e.g. details of every tower).

Larsen reevaluate your performance metrics regularly. Ditto for biz processes.

Brian Vargyas on NM Mgmt: Be proactive, not reactive; BW usage; link history - Dude, Cacti, Nagios. New Dude 4.0 (beta) on SQL DB.

Vargyas - Dude works with any SNMP enabled device, not just MikroTik devices. Any MT board can be an agent to offload central box.

Vargyas - Cacti is open src PHP-based graphing system with web GUI but no notifications. Looks at anything with SNMP OID.

Cameron Crum of Wispmon - started a WISP, needed an IT infrastructure and a way to monitor his network. Visual kind of guy.

Crum is focused on demo'ing the Wispmon product.

Butch Evans speaking on QoS and prioritizing traffic to improve customers' performance - all on MikroTik. Others use Imagestream.

Butch Evans QoS script runs at an aggregation point. QoS won't fix massive overload problems; will help schedule during congestion.

Matt Larsen uses remote power control by Digital Loggers - auto power cycle if no ping on time.

Butch Evans QoS script for MikroTik is $175. Uses IP tables; categorizes most traffic and assigns it priorities; updated as needed.

Butch Evans was trying to emulate NetEqualizer when he started on his MikroTik QoS scripts.

Off to a Tower Technology session but there is no wireless in that room, so no Tweets.

WISPA Tower tech panel - Walked after they had started so I missed the introductions - not sure who is who…

Seems everyone is using 11b or 11g as they regard selecting polarization as critical.

Jack Unger (and at least one panelist) believes narrower channels (10 MHz or 5 MHz) cause the signal to go farther.   Statement that narrower channels have less background noise to contend with, thus the signal goes farther.  Given OFDM, this doesn't make sense to me.  Need to investigate what’s really happening.

One panelist argues for regulated power as the power supplies in the MikroTik's are cheap.

One approach to power and UPS is to use 24v PoE with a central 24v DC supply and two 12v deep cycle batteries.

Everyone advocates UPS.  One guy has 8 hours for every site.

At least one guy tells his customers to buy APCs for the client site.  Tornado zone, take laptop to basement and track tornado in real time.

Weatherproofing for coaxial connections:

1. Courtesy wrap (white tape) protects connector from butyl layer
2. Butyl layer (a mastic like putty)
3. 3M Super 33+ electrical tape (3 layers, shingled down on last layer) to extend at least an inch past the butyl layer.

The Andrew website has good tutorial on weatherproofing antenna connectors.

Use DC4 dielectric grease to protect Ethernet connectors.  Note this is not clear silicon! (even though it looks similar).

Inspect everything at least once per year.

Just posted some pictures from the conference here: http://su.pr/2XQuqp  More to come (will be added to this set!).

Conf has 253 registrations and 40 vendors. Mtg will breakeven or be slightly profitable. 43 new members joined in past one(?) month.

Board Mtg.: I should look into the Ambassador's program... They're looking for members to represent WISPA at regional events.

CALEA update - WISPA spec needs 3 updates to meet new rules; complex negotiation btwn FBI & WISPA. Next issue up is IPv6.

FCC Committee efforts: TVWS (not auctions); TDWR Database (stay 30 MHz away) - problems in Boston & PR); 3650 MHz (4 rule changes).

FCC Comm spent $5K in June, slightly lower than average; but advocacy and meetings are the bulk of what WISPA spends $ on.

Discussion of FCC-specific, or issue-specific, fund raising + volunteers to help engr'g (versus raising dues). Also partnering!

Steve Coran pitch at Marlon's request. (Rini-Coran is WISPA's law firm for DC politics).

Several members suggest that FCC Comm provide boilerplate that members can use to send letters to their representatives.

An aside in my twitter stream, not directly related to the WISPA meeting:
Where do telecom lobbyists come from?  There's a fantastic graph about half way down this page: http://su.pr/1tjZnZ    Hint: they used to work for congress!

Peter Stanforth, CTO, Spectrum Bridges up next on TVWS Trials. First focus on 2ndary mkts - time of day, location, freq. >10yr effort.

Stanforth has nice graphics on what TV white spaces are and how they arise. Hope to get his slides, eventually.

TVWS database administrator. Stanforth suggests we can have competition even here, and still accomplish desired results

Stanforth Summary of trials' field results in 04-186 FCC proceedings.  http://su.pr/2F9dOx

Stanfort: All TVWS trials have worked; getting 3x-5x coverage vs. 2.4 GHz systems; no interference complaints!

Stanforth: sensing unnecessary; drop antenna height limits; use fixed power limits & masks. Make DB higher fidelity than orig req'd.

Stanforth running TVWS BB antenna next to TV antenna in trials. Don't need separation! Must relax power limits and masks!

Stanforth notes that many TV stations are spraying out-of-band energy (a license violation!) but they haven't cared (so far).

Stanforth: if there are multiple database admins, they will coordinate btwn each other once each night, at least as proposed so far.

Rob Kubik of Motorola talking about FAA radars (TDWR) and DFS as basis for renewed outdoor use of 255 MHz of 5 GHz spectrum.

Kubik: experiments show 30 MHz away is ok, even in close (<35 km) to radar; combined w/DB approach should solve problem, but FCC..??

Jack Unger showing TDWR database which WISPA & Spectrum Bridge did jointly - going on-line next week. Meanwhile  http://su.pr/1Xk1SC

Stanforth showing prototype of TDWR database that will be up next week. Currently at http://su.pr/2iHAdO although that will change.

Panel on Buying and Selling WISPs. Prices seem to be from 1x to 2x revenues but many factors. Based on buyer estimate of cash flow expected after the transaction.

Across the board, panel is really cautious about any deal that involves stock or deferred cash. :)

Shiraz Moosajee's advice to buyers: plan on 20% reserve to fix problems and be sure you have 20% beyond that just in case.

Buy/Sell panel: 90-180 day clawback or true up clauses are common, with 20-25% in escrow.

Buy/Sell panel: Even if you don't plan to sell anytime soon, while growing your biz, keep revenue history, per tower.

Buy/Sell panel: Even though everyone prefers cash, very few deals are all cash (and they were fire sales).

Buy/Sell panel: Re buying small neighboring WISPS (100 subs) - frequently done with seller financing over 2-3 years. Estimate growth.

Buy/Sell panel: The smaller the network the less info you are liable to get!

Buy/Sell panel: Need transferability in all your lease agreements as buyers want assets (sellers prefer stock sale for Cap gains).

Buy/Sell panel: Sellers frequently have personal guarantees associated with corporate accts - got to know how to unravel these.

Julius Knapp  http://su.pr/9BXRJs  FCC, lunch keynote: Update on spectrum activities, but starts by hyping BB Plan.

Knapp on spectrum: ack's spectrum that's not yet built, but still pushing FCC/mobile operator's line: need more (licensed) spectrum.

Knapp promoting: spectrum dashboard; incentive auctions; more spectrum for mobile BB & for Backhaul - but this w.b. licensed. Ugh!

Knapp - only items that resonate with me: more unlicensed (Rec 5.11) and opportunistic use of spectrum NPRM (Rec 5.15) - Q3-2010.

Knapp & Ruth Milkman co-chair FCC Spectrum Task Force. Good, but he doesn't mention that FCC only controls part of the spectrum.

Knapp - Pres memo is forcing FCC & NTIA to work jointly on 500 MHz of new spectrum & Pres used words "licensed and unlicensed.

Knapp on TVWS 17 petitions for reconsideration. Expects multiple database mgs to be approved as part of this action.

Knapp acknowledges that 3650 MHz lite licensing has been a significant success, even as there is work afoot to improve things.

Knapp - TDWR protection w.b.: avoid freqs & 30 MHz guardband within 35 km. Make sure this works, so further licensing isn't required.

Knapp: the proceeding on backhaul scheduled for August 5th commissioners' meeting.

Knapp Q&A on Presidential memo suggests that ""licensed & unlicensed"" means some mix. How that's divided is to be argued...

Knapp says Aug 5th mtg will result in increased flexibility in use of spectrum for backhaul. But he wouldn't give details.

Knapp defends existing build-out reqmts. Charles Wu asks about Pt 101 licensing. A: spectrum transparency point is to find squatters.

Ray Savich of Moto describing software tools they have to help WISPs plan their businesses. These are biz tools, not just RF stuff.

Savich on ""Leased line payback calculator"" another tool to help sell WISP services.

Jay Lawrence of Gigabeam showing wireless carrier in Las Vegas who's built a wireless carrier Ethernet network using >50 1Gbps links.

xG Technology is here. Have dropped their original magical claims http://su.pr/1fBB9d for some completely conventional RF technology.

xG now has a proprietary mobile voice solution that runs on unlicensed spectrum. Not interoperable, but more a community cordless solution.

Cameron Crum of Wispmon demo'g their WISP-in-a-box IT solution including qualifying prospects against towers & terrain map. Very cute!

Crum emphasizes taking & preserving pictures of every install indoor incldg where power is connected (tell cust. how to power cycle).

Robert Olive of Wispmon is now pushing their new iPhone apps that work with Wispmon.

Nathan Stooke of WisperISP started in 2003; took a yr to breakeven; 3 yrs to make a salary; today, $2.4M revenue & 20 employees.

Stooke focus on best network and best customer service; has since taken over 15 competitors (many evolved from dial-up days).

Stooke: competitors were dial-up ISPs who entered wireless reluctantly. Diff was he wanted to build a wireless NW and he focused on svc.

Stooke: struggle to find good people; hirer slowly, carefully; some start as contractors, become employees later. He doesn’t provide benefits...

Stooke: employee training espc customer svc - one full day a month devoted to on-going training.

Stooke: run it as if you were setting up to sell it, i.e. keep it clean, fix problems, don't let them linger. Make it a showcase.

Stooke: Has a fire truck with 100' extension ladder that he got for $1K (but spent $26K getting fixed & certified) = temp tower.

Jim Murphy of NetSapiens describing their VoIP solution for WISPs - scales up, also down to system for just 10 simultaneous calls.

Murphy positioning against Asterisk (lower opex, expertise) and hosting (facilities based, more control; potentially better QoS).

Murphy also offering local virtual switch where realtime elements are local but NetSapiens handles everything else.

Now I have to leave to catch a plane, so I'll miss the final prize drawings. :( But this has definitely been worth it!! 

Thanks WISPA!!

WISPA - Wireless ISP Association meeting in St. Louis

I've just landed in St. Louis for a WISPA regional meeting that sure looks national to me.  Of course, I'm from Boston but the first person I talked to was Jim Murphy, COO of NetSapiens who had just flown in from La Jolla California. 

I'm new to the wireless ISP business but it was nice to see several familiar faces in addition to Jim (who I know from my VoIP days in the late 90s), for example, Alex Goldman, formerly of ISPCon and now writing for WISPA and Donny Smith of Jaguar Communications who I had met at FiberFete in April.

During the conference I'm be taking notes via twitter:  @brough

Longer term..., we're seeking a new name

Once we roll out our pilot network (in Boston later this summer), I'll have a lot more to say about how we expect to pull a wireless end run around the duopoly, at least in dense urban areas in the US.

Meanwhile, we are seeking a better name. WirelessEndRun (our internal name) is either brazen or obtuse, or both.  BigBroadband.Net says something about what we're doing but has a lot of negatives.

All suggestions gratefully welcomed.

FiOS Internet performance deteriorating

Sometimes it's working well, then it slows to a crawl.

I've had Verizon FiOS service since the first week it was available in our neighborhood (July 2005). At that time it was advertised as 15 Mbps down and 2 Mbps up, a.k.a. 15/2, for $49.99 per month. Measured speeds actually came very close, as shown here. And these measurements were repeatable.

Over the years the service has been upgraded by Verizon with no action required on my part. Today my service is called "FiOS Internet 20/5." Unfortunately the price has also crept up, to $62.99 per month, again with no action required on my part!

The problem is, today, my FiOS service is highly variable. At times it's very slow. Skype audio breaks up on some calls and works fine on others. But this is anecdotal. Where's the data? 

Gathering data

So ten weeks ago, I started a regular program of testing using a keyboard macro program on a mostly idle PC connected via a wired Ethernet cable to a switch and then to the FiOS service jack. I set it up to run sequences of 3 Speedtests and 3 Pingtests every two hours throughout the day. In our house, these tests seldom ran uninterrupted for more than 30 hours and my manual restarts were sometimes delayed by several days. Also, the accuracy of the macro software wasn't always up to the fine mouse pointing that Speedtest and Pingtest require to select servers. But over the past 10 weeks I've managed to get 646 good Speedtest runs against nearby servers (in Boston) and 549 good PingTest runs against Boston servers. 

This evening I've done some data analysis which confirms the wide variation I saw anecdotally.

 

Next I looked at hour-by-hour averages to see if the performance variation depends upon the time of day, e.g. perhaps everything slows down in the evening... But no, that's not it.

This is the average of all measurements in each one hour period (24 hour clock).

That really surprised me as I expected the slow speed to result from traffic congestion and I know most Internet traffic shows strong time of day variations.  So next I looked at the Pingtest results averaging tests by the time of day in order to get another hour by hour view.  Among other things, Pingtest measures jitter and packet loss. When links become congested the first indication is usually increased jitter. As congestion become significant, you begin to see packet loss.

It's not dramatic, but there appears to be an increase in jitter during the evening hours.

Packet loss is usually zero, but when it does occur, it drives the hourly averages to greater than zero and this graph shows a distinct increase during the evenings.

Conclusions

Unfortunately, from the data and analysis so far, I can't pinpoint what is happening.  The performance of my FiOS service is highly variable, but the problem or problems are not restricted to specific times of day, e.g. high traffic intervals.

If anyone is interested in the measurements I've made so far, just ask and I'll shoot you the spreadsheets containing the raw data.  Meanwhile, I'll be considering what new measurements might shed light on what's going on.

Audiocast tomorrow: Satellite phones, spectrum games and more

Tomorrow, Tuesday the 15th at 11am eastern time, I'll be live on an audiocast organized by Carl Ford of 4GWE and TMCNet.  

The title is "4G is in the Stars: Satellite to Terrestrial" and speakers include Barlow Keener, Lyman Chapin and yours truly.

The prize is 68 MHz of spectrum at 1.4 GHz.  In the US and Canada, this spectrum has been allocated for Mobile Satellite systems but it can also be used for Ancillary Terrestrial Services - that is services that are ancillary to the satellite services! This spectrum would be good cellular spectrum if you could get it, being above the 800 MHz original cellular bands but below the 1.9 GHz PCS bands. Technically, the satellite signals go up and down while the ancillary signals go mostly horizontally, so they are relatively independent. The big question is: Can anyone afford to launch satellites and run satellite services just so they can also use this spectrum for LTE services at ground level?

Gigaom has been skeptical, but when you stack up the estimated $5B to build a network against the possible value of this spectrum at auction, i.e. 68 MHz at US$1.2 per MHz-POP (the price paid in the US 700 MHz auctions) and 335 million POPs in the US & Canada you get roughly $27B. That math could work...

Join us tomorrow at 11am eastern by registering here.

Top cities ranked by Broadband Speedtest results

 

For those who are US-centric, note that MD is not Maryland, it's Moldova!

These results are aggregates of measurements made at Speedtest.net.  These and other results have been published by Ookla (the company that created Speedtest.net and Pingtest.net).  See Net Index for more results.

It's interesting that many of these cities are in eastern Europe, e.g. Latvia, Moldova, Romania, Bulgaria and the Ukraine.  Indeed, three of the top 15 cities are in Latvia.  I don't have current data on Latvia but I wonder if it benefits from the same relatively free access to rights-of-way that is present in Bucharest and several other parts of the world.

At eComm, then FiberFête; Live notes will be on Twitter

I arrived in San Francisco last night for the Emerging Communications Conference which begins today.  I'll be taking notes live on Twitter, not here. 

eComm runs three days and I'm hosting a panel on the US National Broadband Plan on Tuesday.  The 3rd day of eComm is entirely devoted to Augmented Reality. Unfortunately, I have a conflict and will have to miss the 3rd day.

On Wednesday and Thursday, I'll be at FiberFête in Lafayette Louisiana.  I'm extremely interested in augmented reality so I hate to miss the 3rd day of eComm, but I also have a long standing interest in telecom and Internet policy and industry structure.  What's more, I'm involved in a start up that aims to do an end run around some of the structural problems holding back broadband in the US.

Both conferences have excellent programs, but in each case it's the people who are attending, even more than the program, that are the attraction and have caused me to slice and dice my schedule this week.

For my take on the conferences, as they transpire, follow my primary Twitter feed.

Africa moves from satellite to fiber links

2009-2010 marks an exciting transition for the Internet in Africa. 

Historically, most countries had only satellite connections or a connection to a single submarine fiber optic cable (SAT-3) controlled by an incumbent monopolist. Not surprisingly, prices for SAT-3 bandwidth in the African countries it serves were high (US$4,500–12,000 per Mbit/s per month, vastly more than than bandwidth prices in the US or EU).

But finally, things are changing, radically.  Beginning in 2009, the Seacom cable connected eastern and southern Africa with Asia and the TEAMs cable reached Kenya. Now four more cables (Glo One, Main One, EASSy and LION) are coming on line in 2010, with WACS and ACE expected in 2011-12. Steve Song has an excellent map and more details here.

Impact on Satellite services

Balancing Act Africa has a new market study out which projects African bandwidth markets through 2014. Among other conclusions summarized in recent letter from Russell Southwood:

The overall balance of satellite vs fibre use in Africa’s top Sub-Saharan markets 20 markets goes from 45.6% vs 54.4% in 2008 to 11.9% to 88.1% in 2014. Of these top 20 markets, the top 5 markets (South Africa, Nigeria, Kenya, Angola and Sudan) make up the majority of bandwidth demand across the continent and are the countries that will experience the fastest bandwidth growth over the period. So satellite operators and resellers will not only be selling into a smaller share of the overall bandwidth market but will become niche players in many countries. There will be growth but most of it will be on fibre.

After three and a half years since December 2005 in which only ten satellites were launched with coverage over Africa (four of which failed), at least 36 new satellites will be launched by the end of 2013, costing between US$4.4 billion and bringing the equivalent of 26,325 MHz of additional capacity over the region. By the time the second constellation of O3b satellites is launched, there will be almost as much Ka-band capacity over Africa as the total stock of C- and Ku-band capacity.

The satellite operators have invested huge amounts in new and replacement satellites. US$ 4.395 billion will be invested in new and replacement satellites against US£2.15 billion in seven international submarine cables, excluding ACE where the budget has not yet been announced. The satellite operators are investing at a time when the tide is turning against satellite use.

What are satellite operators thinking?

Broadband speeds - Boston and Bucharest

Recently I was conversing with a friend from Romania and we got to discussing consumer access to the Internet. Not surprisingly, connectivity in Bucharest is substantially faster than what I have here in the Boston area (even though I have Verizon FiOS service).  Anyway, rather than go by two isolated samples, I thought to look at the international records at speedtest.net to see averages of many, many measurements.

Notice that the first three measurements on the Boston side are business services, not things a consumer could afford. On the Bucharest side, Voxility is a wholesaler but #2 and #3 are selling to anyone.

 Yes, it's one rather specific set of measurements, but still...

City comparisons

The greater Boston metropolitan area has a population of ~4.5 million making it the largest city in New England and the tenth largest metropolitan area in the US.  Bucharest is the capital of Romania and the Bucharest metropolitan area has a population between 2.15 and 3 million. Bucharest is a bit older than Boston and today has a bit higher density, while Boston has somewhat more high rise buildings.  Still the cities are not so dissimilar that it would explain the wide divergence in speeds of Internet connectivity.

Future eComm events may be invitation-only

There is an interesting post from eComm conference organizer Lee Dryburgh here.  Now that the agenda for next week's conference is nailed down, Lee is considering whether the audience for future eComm events should also be subject to selection (as speakers are today).  

From my perspective, eComm is always very special because almost all the speakers are interesting and the audience has been loaded with interesting people.  Credit for the quality of the speakers goes to Lee.  There is an eComm advisory board (to which I've occasionally contributed), but Lee is the driving force in creating the agenda full of great speakers.

If you are attending eComm next week, or have attended any eComm event, or have benefited from the rich eComm material available on the web (videos, more videos, audio, not to mention slides and photos at the "previous" tab here), you may wish to voice your opinion on open versus invitation-only.  

Lee is looking for feedback here.
