Abstract:
1. A system for routing signals in a Distributed Antenna System (DAS), the system comprising: a plurality of base transceiver stations (BTS), each having one or more sectors; one or more digital access units (DAUs); a plurality of repeater digital units (RDUs), each RDU configured to communicate with at least one of the plurality of BTSs and operable to convert the communications to and from the at least one BTS between analog and digital, and further operable to route digital signals optically to the one or more DAUs, wherein each DAU is further operable to route the digital signals from a BTS to another BTS, and from one DAU to another DAU; and a plurality of digital remote units (DRUs) located at a location remote to the one or more DAUs, wherein the plurality of DRUs are operable to transport signals to the one or more DAUs, wherein each DAU is further operable to route digital signals from a DRU to a BTS from the plurality of BTSs.
