Patent ID: RE38787

Claim:
A radio frequency management system for reallocation of radio spectrum among a plurality of wireless communication networks using differing radio frequency modulation protocols and differing radio frequencies to communicate with a plurality of frequency and protocol agile portable radio devices each of which is responsive to portable radio device control signals to change its operating frequency and modulation protocol, comprising capacity detection means for generating a frequency request signal upon determining that a first wireless communication network operating using a first radio frequency spectrum allocated to said first wireless communication network and using a first modulation protocol, is at or near full capacity, frequency reallocating means responsive to a frequency request signal for reassigning temporarily radio spectrum from a second wireless communication network operating using a second radio frequency spectrum allocated to said second wireless communication network and different from said first radio frequency spectrum and using second modulation protocol, to the first communication network determined by said capacity detection means to be at or near full capacity, and means for causing portable radio control signals in at least some of the frequency and protocol agile portable radio devices to change their operating frequency and modulation protocol to permit the portable radio devices so changed to communicate over the temporarily reassigned radio spectrum.
