Abstract
A communication system implements a method of bidirectional communication of signals to/from one or more wireless transmit locations. Transmitting signals to one or more wireless transmit locations includes obtaining a plurality of signals having different protocols, from a plurality of base stations, then converting the plurality of signals into common digital network protocol signals, and transmitting the common protocol signals over a transmission network to one or more wireless transmit locations. Receiving signals from one or more wireless transmit locations includes transmitting digital signals using a common protocol, from one or more wireless receive locations over the transmission network, converting the received digital signals into a plurality of signals having different protocols corresponding to a plurality of base stations implementing said different protocols, and providing the plurality of differing protocol signals to said corresponding plurality of base stations.

30. A method of communicating signals to one or more wireless transmit locations, comprising the steps of:
-
receiving a plurality of signals having different protocols, from a plurality of base stations, wherein each base station operates using a particular protocol and frequency band;
converting the plurality of signals into common network protocol digital streams, including the steps of;
(i) receiving a communication signal from a base station which uses a digital protocol, converting the base station data signal to a common baseband channel protocol digital stream, each common baseband channel spanning a fixed bandwidth including one or more frequency division carriers;
(ii) receiving a communication signal from a base station which uses an analog protocol, converting the base station analog signal to a common baseband channel protocol digital stream, by performing analog to digital conversion on the analog signal using a network reference as a sampling clock;
formatting the digital streams into data packets for routing throughout a transmission network; and
transmitting the packets over a packet transmission network to one or more transmit locations.
