Spectrum Policy Needs to Become More Nimble Most Spectrum Is Not Used Most of the Time We Are Experiencing Exponential Mobile Data Growth We Need to Promote Technologies That Make More Efficient Use of Spectrum Increasingly sophisticated online databases that automate spectrum allocation and use. Wideband radios with sensing, channel notching, suppression, bonding, and other capabilities.

Our Ask of Policy Makers We need policy makers to create opportunities for new technologies that are available today AND more nimble policy frameworks We need policies that allow dynamic access to more spectrum across a range of bands, enabling complementary shorter-range and wide-area networks, and automated and adaptive solutions. Powerful, yet inexpensive hardware and software technologies now offer new and more attractive solutions to our longstanding spectrum allocation problems (cognitive radios, online databases that automate spectrum allocation and data networks that can dynamically modulate their transmission power) Adopting these advances will enhance the user experience by enabling literally billions of new devices as they go live over the course of the next decade on the Internet of Things. TVWS is a FIRST STEP The FCC’s TVWS regulations create a version one opportunity. Greater capabilities and spectrum bands can and should be enabled.

White Spaces Trials & Demos WA NV TX VA NC Isle of Bute Helsinki Completed or Ongoing Cambridge Japan South Korea Planned Singapore

NAB Show, Las Vegas, Nevada Xbox Live 1080p HD video streaming over TV white spaces spectrum.  Used single 6 MHz channels supplied by MSR prototype database. Simulated licensed wireless microphone registration, showing seamless channel changing. Consistent throughput of approx. 8.8 Mbps downstream and approx. 2.3 Mbps upstream.  Long range links established from the Wynn and Hilton Hotels -- .8 miles and .5 miles, respectively.     Achieved throughput of 5 Mbps downstream and 2 Mbps upstream on .8 mile link.

Cambridge, England Trial Objectives Assess the potential of TV white spaces to: Deliver cost-efficient broadband access to rural communities Offload wireless data demand in urban centres and Open the way for innovative business models. Test and measurement program to help inform Ofcom’s regulatory proceedings.

Trial Partners

Trial Overview Overview Multiple use cases: Location based services, machine-to-machine, local content delivery, rural broadband. Wide area coverage: When completed, 17 base stations will cover much of the city centre and some surrounding areas. Unprecedented industry partnership: Arqiva, BBC, BT, BSkyB, Cambridge Consultants, CRFS, Neul, Nokia, TTP, Samsung. More to come. Multiple hardware suppliers: Adaptrum, KTS, Neul, and 6Harmonics. Multiple whitespaces databases: Microsoft and Spectrum Bridge. Government support: Test licenses approved with cooperation of Ofcom. Local government support. The Cambridge trial will be of unprecedented scope, both in terms of the partnership and the use cases.
