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.
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).
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.
