Vanu announced last week it would partner with Raytheon in the second phase of the Defense Advanced Research Projects Agency (DARPA) Next Generation (XG) program, which is working to develop cognitive radio technologies. Vanu will provide its software radio technology and waveforms, while Raytheon will provide its spectrum management and control techniques. The companies eventually will demonstrate products that will detect and avoid other uses in the 900 MHz band, typically cordless phones. A timeframe for the demonstration was not announced.
