1. Centrally located equipment for use in a wireless telephone system that utilizes a broadband distribution network to carry telephony signals between a telephone network and wireless telecommunications devices using carrier signals, said centrally located equipment comprising:

  • a first circuit that interfaces with said telephone network, said first circuit receiving telephony signals from said telephone network and encoding said telephony signals into a first encoded telephony signal that is used to modulate a carrier signal having a first frequency to create a first IF carrier signal, and transmitting said first IF carrier signal; and

    a second circuit that interfaces with said first circuit and with said broadband cable network, said second circuit receiving said first IF carrier signal from said first circuit and processing same before translating the frequency of said first IF carrier signal to a second frequency to create a first RF carrier signal that is transmitted over said broadband distribution network to said wireless telecommunications devices; and

    wherein telephony signals from a wireless telecommunications device are encoded and used to modulate a carrier signal having a third frequency to create a second RF carrier signal that is transmitted over said broadband distribution network to said second circuit, wherein said second circuit processes said second RF carrier signal and then translates the frequency of said second RF carrier signal to a fourth frequency to create a second IF carrier signal that is transmitted to said first circuit, wherein said first circuit demodulates said second IF carrier signal to obtain said encoded telephony signal from said wireless telecommunications device, and wherein said first circuit decodes said last mentioned encoded telephony signal to obtain the telephony signals from said wireless telecommunications devices which are sent to said telephone network.
