  2. The review of TV White Space IEEE 802 Interim Session LA, U.S.A Jan 2011 Slide 2 Cheolho Shin and Sangsung Choi., ETRI

  3. TV White space (1) • TV White space - slivers of unused spectrum that sit between licensed broadcast channels • FCC 10-174, “Unlicensed Operation in the TV Broadcast Bands” - September 23, 2010 • Advantages of TV White space - Use the similar TV channel frequencies all over the world - There is no special interference source except the TV signals. - Excellent propagation characteristics that allow signals to reach farther and penetrate walls and other structures. Slide 3 Cheolho Shin and Sangsung Choi., ETRI

  4. TV White space (2) • Applications for TWS Slide 4 Cheolho Shin and Sangsung Choi., ETRI

  5. TV White space (3) • Fixed device and personal/portable devices can be operated in the TV • white spaces on an unlicensed basis Slide 5 Cheolho Shin and Sangsung Choi., ETRI

  6. TV White space (4) • Main issues for Unlicensed TV bands devices(TVBD) - Eliminating the requirement that TV bands devices that incorporate geo-location and database access must also listen (sense) to detect the signals of TV stations and low power auxiliary service stations (wireless microphones) - While the sensing requirement for TVBDs is eliminated, continued development of this capability is encouraged because it holds promise to further improvements in spectrum efficiency in the TV spectrum in the future and will be a vital tool for providing opportunistic access to other spectrum bands - TV bands databases that provide lists of available channels to TVBDs must receive approval by the FCC Commission Slide 6 Cheolho Shin and Sangsung Choi., ETRI

  7. A example of Channel allotment in TWS • Can use 5 Channels per 1 TV Channel • Can configure 5 piconets simultaneously. Slide 7 Cheolho Shin and Sangsung Choi., ETRI
