San Diego, CA - We gave a tutorial on "Coexistence in the TV white space" on Monday night. The tutorial included presentations from members of 802.19, 802.11 and 802.22. We held a short joint meeting with 802.11af and 802.22 to discuss questions from the tutorial. Task Group 1 heard 10 technical presentations during the week on: geolocation for cognitive access, data representation, GERDCS, concepts of operation, reference model, expectations of 802.19.1 from a primary protection point of view, channel set transitions, coexistence decision making topologies, channel selection support, and security. In September Task Group 1 will begin hearing proposals on the draft. After the meeting 802.19 hosted a free workshop on TV white space coexistence which was attended by over 100 people. Attendance included many people who do not normally attend 802 meetings.
