The Great Wireless Hope David Sifry, Sputnik Duncan Davidson, SkyPilot Glenn Flieshman, Journalist Dave Hagan, Boingo Martin Rofheart, XTreme Spectrum   missed the beginning of this session   Duncan: many backed off of WiFi because of security without understanding the issues   Killer apps for unlicensed spectrum? Dave: all the things you want to do on a normal basis wherever you go David: likes to surf on the crapper and its incredibly sticky How has FCC regulating this space effected what you are doing? Martin: Had to get authorization to build, manuf and sell our devices.  The process has evolved over decades to serve large companies, does not reflect requirements of tech startups Duncan: In a political box.  Creating a duopoly in cable and wireless and regional monopolies in wireline.  Staffers are great people trying to make something happen, but spectrum is lying fallow -- the 3rd pipe, the breakthrough to bust open the last mile.  WiFi maybe 2.5, 5G.  Open, robust, innovative. Glenn: will incumbents overtly fight the 3rd pipe to capture available open spectrum?   Dave: congestion at big conferences.  at 802.11 planet a success.  Its managable and all about forecast and fulfillment.  The challenge is at the backbone (IP Transit) Martin: Only a matter of time until its solved (commons): either carve it up (license) or cognitive radios (open).  Open wins because consumers are demanding. Duncan: Meshed architecture, fully distributed, scalable (I doubt it, each node adds a hop -- diseconomies of span) David: polite radios Dwayne: Chairman Powell's taskforce www.fcc.gov/sptf Current is command is control, to move to a commons and a property model.  Unlicensed easement - every license has a portion of band that is open as long as it doesnt exceed a temperature.  First rule making for this starts tomorrow, Request for Comment issued -- the first tangible output from taskforce.  Process continues for the next two years. Glen: 802.11h amends .11a and allows deployment in Europe, differs by dynamic channel management and power control (polite radios), could be rolled into b & g to realize polite radios. Duncan: The uniband has been adopted somewhere in the world.  Japan, England & Australia.  The pressure to get this out will open it in the rest of world. Duncan: Backhaul on the Mesh...distance between hops almost all is used for relay... one thing you can do is have longer radio throws with WiFi (see Tim Pozar's stuff), the other is if you put the gateways deep into nieghborhoods (still think there are real limits here, especially because gateways already exist somewhere else at the terrestrial backhaul network) David: Texas Instruments reduced standby power requirements by 10x -- the real potential battery saver when the chipset hits the market. Martin: still going to have the uptime radio power requirements.  Also, UWB Developer Kits shipping Rohit: can we go below layer 3 for access.  Duncan: you are trying to create a carrier grade product, and it is better to get it down to layer 2 to provide an alternative to terrestrial David: emergency network mesh experimentation projects (SMS hopping its way to 911) Glen: Zigibee, low power low bandwidth alternative (for remote controls) 7:18:03 PM    comment []
