Abstract
Simplified centrally located equipment for use in a wireless telephone system that uses of an existing broadband distribution network to carry telephony signals between an existing telephone network and remote transceivers sites in defined cells or sectors is disclosed. The simplification is accomplished by reducing the number of frequency translation steps between elements of the centrally located equipment by using the same carrier frequency for signal handling within the elements of the centrally located equipment as is used to transmit telephony signals between elements.
