Patent for a New Method of Spectrum Sharing
ECE William Lincoln Smith Professor Tommaso Melodia received a patent for creating a “Method for spectrum sharing by primary and secondary networks based on cognitive beamforming.”
Abstract Source: USPTO
Method and systems of sharing a frequency spectrum between a primary wireless network and a secondary wireless network coexisting with the primary wireless network are provided. At a node of the secondary network, at a bottom of a protocol stack integrated between a plurality of antennas and upper layers of the protocol stack, a beamforming scheme is determined for transmission to scheduled users of the secondary network. Using this technology, a newly-deployed wireless network can access a spectrum band based on cognitive beamforming without mutual temporal exclusion. i.e., without interrupting the ongoing transmissions of coexisting wireless networks on the same bands, and without cross-technology communication.
