Patent ID: 8655369

Claim:
A co-existing multi-radio system comprising: a plurality of base station systems, at least one of the base station systems comprising: a primary base station subsystem, operating exclusively in a fixed frequency band; and a cognitive radio base station subsystem, operating exclusively in an unfixed frequency band; a plurality of first mobile devices, each first mobile device configured for: self-reconfiguring by selectively choosing an operating radio frequency for communication; choosing a modulation type for a predetermined transmission system; controlling a power of transmission by selectively switching among a plurality of transmission power levels; sensing a set of communication environment information comprising: a frequency band utilized in the communication environment; a transmission protocol utilized in the communication environment; a spectrum shared and received among the first mobile devices in the communication environment; a carrier frequency of RF signals in the communication environment; a bandwidth utilization rate of the communication environment; a received signal strength indication (RSSI) of RF signals in the communication environment; and a signal-to-interference and noise ratio (SINR) of RF signals in the communication environment; and analyzing communication environment information to selectively determine the operating radio frequency of each first mobile device; at least one second mobile device, in communication with at least one of the first mobile devices, either directly or via at least one base station system, operating exclusively in a fixed frequency band of the communication environment; wherein, each second mobile device is configured to communicate with each of the first mobile devices, the primary base station subsystem, and the cognitive radio base station subsystem; wherein, the plurality of base station systems are configured to communicate with each other; wherein, a respective one of the plurality of first mobile devices performs self-configuration to become a second mobile device when connection to the primary base station is required.
