    Abstract: A digital distributed antenna system (DDAS) that regains the capability to perform simulcast to multiple simulcast groups while using a base station's direct digital output is provided. The User Plane data is adapted for simulcast and also for eliminating time delay ambiguities across multiple simulcast digital radios. In addition, the Control and Management Plane is aggregated across multiple remote units to allow a non-modified donor digital base station to control simulcast groups. The result is a low cost digital DAS that can efficiently distribute the capacity of a digital base station to solve coverage and capacity requirements in a manner similar to that now accomplished using a traditional base station with RF in/out.

    Abstract: A Time Division Duplexed (TDD) digital distributed antenna system (DDAS) that performs simulcast distribution to multiple simulcast groups while using TDD time advanced burst to negate the data rate reducing effects of transport delays. The User Plane data is adapted for eliminating time delay ambiguities across multiple simulcast digital radios. In addition, the Control and Management Plane is aggregated across multiple remote units to allow a non-modified donor digital base station to control simulcast groups.

    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.
