Super Wi-Fi TV White SPace and Wireless Broadband Inclusion Super Wi-Fi TV White SPace and Wireless Broadband Inclusion Presentation Transcript

  • Super Wi-Fi: TV White Space and Wireless Broadband Inclusion Blandin Foundation Webinar September 12, 2013 Michael Calabrese Director, Wireless Future Project Open Technology Institute New America Foundation calabrese@newamerica.net
  • Public Interest Spectrum Coalition Unlicensed Access to Vacant TV Channels was first advocated in the U.S. by NGOs to facilitate: Wireless broadband for rural and unserved areas: Economic development is increasingly linked to broadband access More robust Wi-Fi networks as both a complement and alternative to licensed carrier networks The U.S. NGO White Space Coalition included: • Consumer Federation of America • Consumers Union • Leadership Conference on Civil Rights • EDUCAUSE (University CTOs) • National Hispanic Media Coalition • Free Press • Public Knowledge • New America Foundation • Native Public Media . . . (and other groups)
  • Location, Location, Location! TV Band Spectrum (< 1 GHz) is uniquely valuable: - Larger Coverage Areas - Lower Infrastructure Costs - Better In-Building Penetration
  • What is Super Wi-Fi? Super Wi-Fi  Vacant local TV channels opened by the FCC that are useable on an unlicensed basis for broadband applications (e.g., Wi-Fi as wireless backhaul), narrowband M2M, etc  Utilizes Unused TV Broadcast Frequencies (TV White Spaces)  Lower Frequencies (below 700 Mghz) allow signals to cover far larger areas than traditional Wi-Fi and penetrate or bend around obstacles (trees, hills, deeper indoors) relative to higher frequencies 54 88 174 216 470 698 512 614 608 37 Lower VHF Upper VHF UHF Public Safety Wireless Mics RA Fixed TVWS Devices Portable/Personal TVWS Devices 76 72 TV ch 2-4 TV ch 7-13 TV ch 21-365-6 TV ch 14-20 TV ch 38-51 4
  • AIR.U: Rural College Communities Initiative by Consortium of Higher Education Groups to Deploy Bandwidth to Rural College Communities Rural and small city colleges/universities are well suited for Super Wi-Fi innovation • Higher Bandwidth Requirements (increasing) • Fewer Bandwidth Alternatives • Fewer Broadcasters means far more White Space Pilot Phase Deployments in Development:  West Virginia University  Garrett County Maryland (unserved rural areas)  California State U/Stanislaus (broadband to students at home)  Historically Black Colleges in S.C. (extending coverage/capacity) 5 Declaration Networks Group, LLC
  • AIR.U: University of West Virginia TV White Space Network Blankets University tram system with Wi-Fi Connectivity • White Space Network Extends Public Wi-Fi Internet Access (Fixed & Mobile) • 15,000 Student/Faculty Commuters per day • 3.5 miles of track – 5 station platforms 6 University W. Virginia Personal Rapid Transit System PRT route identified in orange
  • Gigabit Libraries Network • “Libraries WhiteSpace: National Pilot” • More than 90% of US libraries already use unlicensed wireless spectrum (wifi) to provide Internet access to tens of millions of people. • First national-scale White Space Trial in US:  Deliver more bandwidth to libraries without high-speed wireline connections (e.g., KC enviro library)  Explore the utility of TVWS to extend and support more basic, open, no-fee Wi-Fi library hotspots (e.g., satellite library hotspots, book mobile Internet access)  Seek benefits of combining the near universal compatibility of Wi-Fi with the range and penetrating capabilities of White Space devices. • Round One: From 50 proposals from all regions of the country, six chosen in KS, NH, CO, NH, MS, CA, IL • KS & NH are multi-library, statewide consortia: “Kansas K20-Librarians White Space Consortium” • Every state encouraged to investigate the prospects for a state wide library consortium pilot. • If half the nation’s 16,000+ libraries deployed TVWS networks, each ave. 5-6 remotes, it would QUADRUPLE the number of public library hotspots. • GigLibraries.Net
  • TVWS: Cost-Effective Community Networks Targeting Unserved Rural Areas In a rural, forested and rugged Garrett County, MD, wireless backhaul from distant State fiber to TVWS base station hubs . . . . . . will offer 3,000 unserved homes and businesses > 3 mbps Wi-Fi service for $30/month. 8
