Claim Text:
1. A computer-implemented process for optimizing the coexistence of a plurality of different wireless networks that concurrently operate in a common geographic region, comprising: using a computer to perform the following process actions: receiving a query from a wireless node requesting advice on specific portions of a radio frequency spectrum to use, wherein said wireless node is a wireless computing device operating in one of said wireless networks comprising a plurality of wireless nodes; receiving explicit information that the wireless node locally observes about current radio frequency spectrum usage, said information comprising specifying portions of the radio frequency spectrum that are not currently being used by any licensed incumbent users in the current geographic location of the wireless node; running a spectrum recommendation procedure to generate advice on recommended portions of the radio frequency spectrum for the wireless node to use in order to minimize one or more of interference in the spectrum, or noise in the spectrum, or contention in the spectrum using at least the received explicit information that the wireless node locally observed about current radio frequency spectrum usage; and sending a recommendation reply to the wireless node comprising information specifying the recommended portions of the radio frequency spectrum for the wireless node to use in order to minimize one or more of interference in the spectrum, or noise in the spectrum, or contention in the spectrum.
