High Spectrum Efficiency Technologies

Azure Summit Technology and Shared Spectrum Corporation propose to improve the spectrum efficiency of ad-hoc networks while at the same time maintaining a high level of anti-jam robustness. Our approach is focused around four main strategies; time and frequency assignment and separation, simultaneous transmit/receive, non-greedy beam steering and neighbor nulling, and integrated dynamic spectral access and media access control (DSA/MAC) considering time, frequency and space. These strategies are driven by the observation that the limiting RF feature of dense ad-hoc networks, short of red force jamming, is the increase in background noise generated by the sum transmissions of all radios in the network.
