System and method for the delivery of high speed data services over dedicated and non-dedicated private land mobile radio (PLMR) channels using cognitive radio technology

A point to multipoint wireless system for communication between a dispatch center hub and a plurality of remote terminals, the system comprising:

• a base station controller in communication with the dispatch center hub;
• a plurality of base stations, each of said plurality of base stations in communication with the base station controller, each of said plurality of base stations being located at a corresponding one of a plurality of private land mobile radio (PLMR) tower sites;
• a plurality of remote radios in communication with at least one of said plurality of remote terminals;
• at least one PLMR channel scanner embedded in each of said plurality of base stations;
• at least one PLMR channel scanner embedded in each of said plurality of remote radios,
• wherein each of said at least one PLMR channel scanners embedded in each of said plurality of base stations and remote radios is configured to scan the PLMR channels to determine which of the PLMR channels is idle at any point of time;
• and
• wherein each of said plurality of base stations maintains two-way data communication over idle PLMR channels with the plurality of remote radios in its serving area;
• wherein each of said plurality of remote radios comprises:
• a Radio Frequency (RF) front end in communication with said at least one PLMR channel scanner embedded in each of said plurality of remote radios;
• a remote radio (RR) cognitive controller in communication with the RF front end and the remote radio scanner;
• a modem in communication with the RF front end and said RR cognitive controller;
• a plurality of transmitters in communication with said RR cognitive controller, each of the plurality of transmitters configured to perform modulation for a single PLMR channel;
• a plurality of receivers in communication with said RR cognitive controller, each of the plurality of receivers configured to perform demodulation for a single PLMR channel;
• an inverse multiplexer in communication with said RR cognitive controller, said inverse multiplexer configured to convert a high bit rate data stream into multiple lower bit rate data streams for delivery to said plurality of transmitters;
• and
• a multiplexer in communication with said RR cognitive controller, said multiplexer configured to convert multiple lower bit rate data streams received into one high bit rate data stream for delivery to a local user;
• wherein each of said plurality of base stations comprises a cognitive controller;
• and
• wherein said cognitive controller determines the idle PLMR channel allocation for said two-way data communication based upon channel occupancy reports generated by and received from said RR cognitive controller of at least one of said plurality of remote radios.
