Abstract:
1. A method for transmitting a message from a first phone to a cell phone utilizing a central radio pool/traffic router, the method comprising the steps of: receiving a voice signal from the first phone at a switch, the voice signal intended for the cell phone; passing the voice signal from the switch to a radio; modulating the voice signal at the radio onto a radio channel to produce a modulated voice signal; feeding the modulated voice signal to an RF interconnect switch; passing the modulated voice signal from the RF interconnect switch to an RF combiner/splitter; combining by the RF combiner/splitter the radio channel with other radio channels used by other calls to form a composite RF signal; passing the composite RF signal to an optical modulator/demodulator; modulating an optical carrier by the optical modulator/demodulator using the composite RF signal, thereby translating the composite frequencies to optical frequencies; sending the modulated optical carrier to a base station over an optical fiber link; demodulating the optical carrier to produce a composite RF signal; and transmitting the composite RE signal from the base station to the cell phone.
