Shared Spectrum has been awarded several Federal government research and development contracts to turn spectrum sharing theories into reality.

We are currently working with the following agencies to help them increase their spectrum capacity:

DARPA - awarded $17M XG Contract in 2005

• » 26-month agreement funded by the Defense Advanced Research Projects Agency (DARPA)
• » Phase III of NeXt Generation (XG) Communications program
• » Managed by the Air Force Research Lab, Rome, NY
• » Involved developing, building and testing radios that dynamically adapt to changing spectrum environments
• » Completed XG system design developed under previous phases of XG program
• » Developed XG prototype systems
• » Demonstrated radios and systems in the field (military and urban environments)

Objectives:

• » Access 10 times more spectrum
• » Near-zero setup time
• » No harmful interference to existing users while sharing spectrum
• » Simplify RF spectrum planning, management and coordination

August 2006: Live demonstration at Fort A.P. Hill, Virginia.

• » Six mobile 802.16-based XG radios operating on same spectrum as a suite of fixed, instrumented military and commercial legacy radios
• » Wide-area instrumentation system recorded XG radio connectivity and performance of legacy radios
• » Demonstrated operational utility of XG:

• » Shares spectrum while causing no harm to existing military radios in compliance with emission/regulatory rules;
• » Allows more radio networks and communication capacity than currently possible using existing procedures; and
• » Operates in presence of severe electromagnetic interference (i.e., jamming)
• » Overall program capabilities and potential immediate benefit for DOD operations shown

• » First in series of fully integrated XG system tests exercising all elements of the XG system:

• » Ultra-sensitive detectors
• » Distributed sensing
• » Complex interference avoidance algorithms,
• » and Policy-based software control
