  3. Deployment History (1) • February 2, 2010. Demonstrated shuttle network to a delegation from AgênciaNacional de Telecomunicações Brazil (ANATEL)Brazil including Max Martinhão, the General Manager for Radio Frequency Spectrum in Brazil • January 14, 2010. Demonstrated network to a delegation from Fisher Communications, Inc. (KOMO TV-ABC & KUNP TV—Univision) including Senior Vice President of Operation Robert I. Dunlop • January 11, 2010. Demonstrated network to a delegation from theState Administration of Radio, Film, and Television (SARFT)Chinaincluding Deputy Director General of Science and Technology China, Mr. Wang Lian • Octber 22, 2009. Demonstrated network to a delegation from the Telecom Regulatory Authority of India (TRAI)including Chairperson Dr. J. S. Sarma. • October 16, 2009.  Reached a significant and historic milestone! Successfully deployed WSN between buildings on Microsoft's Redmond Campus.  To the best of our knowledge this is the first urban WSN. Technologies tested include: • An opportunistic data network in the UHF and VHF bands • Channel occupancy database service with real-time Longley-Rice RF propagation modeling over NASA Terrain Data • Coexistence with wireless microphones • Handling mobile clients • Varying channel widths to accommodate varying needs of the application Microsoft Research

  4. Deployment History (2) • July 15, 2009  Outdoor tests succeeded. Achieved communications with 1% BER between white spaces devices transmitting at 100 mW and separated by more than 0.5 Km.  Tests proved that enterprise wireless network coverage can be significantly enhanced with a combination of Wi-Fi & White-Fi. • July 6, 2009 Received FCC experimental license to test a deployment of a white space network. • June 30, 2009 Version 1 of our channel occupancy database came online • January 15, 2009 Demonstrated a fast channel discovery algorithm (a.k.a SIFT) and an efficient channel assignment algorithm (a.k.a. MCHAM) to achieve high throughput in a WSN • October 23, 2008 Happy birthday! the first white space network (WSN) is alive and kicking!  Successfully demonstrated a network of five nodes communicating over the UHF white spaces. The network was built in our lab using the KNOWS hardware operating at 1 mW. We demonstrated (a) wireless microphone sensing, (b) Opportunistic networking, and (c) Variable channel width   • January 27, 2003P.

  11. Press– Sample Headlines Microsoft Research

  12. Press– Sample Quotes The project, dubbed “White Fi,” is one of the most advanced in the field, both dealing with the hardware side but also creating the networking protocols to handle the specific challenges. Softpedia (Aug. 19, 2009) Microsoft researchers have taken a step closer tofinally turning unused analogue TV spectrum, known as "white spaces", into unlicensed spectrum that can be used to deliver new wireless broadband service CNET.COM (Aug. 19, 2009) The Microsoft Research team has addressed many of these issues with WhiteFi. —that early promise of "WiFi on steroids" might turn out to be surprisingly accurate, after all. Nate Anderson, Arstechnica, August 27, 2009 The actual engineering requirements to accomplish this frequency switch are non-trivial. Microsoft Research’s ”KNOWS” project has taken up the task and made some pretty remarkable advances. Scott Merrill, Crunchgear, August 28, 2009 One of the best prospects for the future is the opening up of “white spaces,” unused parts of the spectrum. One of the most advanced research projects….. Lucian Parfeni, Web News, August 18, 2009 Microsoft researchers have taken the next step toward turning old UHF analog TV spectrum into rural wireless broadband networks that would operate like Wi-Fi but with greater range.
