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.

Digital distributed antenna system

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.
