Das integrated digital off-air repeater

Abstract

Embodiments may allow remote base transceiver stations (BTSs) physically located away from a local source of users to be able to provide local service as if the remote BTSs were at or near the local source of users. Some embodiments may include a plurality of BTSs, each having one or more sectors, and one or more digital access units (DAUs). Embodiments may also include a plurality of repeater digital units (RDUs), where each RDU may be configured to communicate to at least one of the plurality of BTSs and may be operable to route signals optically to the one or more DAUs. Embodiments may also include a plurality of digital remote units (DRUs) located at a location remote to the one or more DAUs, wherein the plurality of remote DRUs may be operable to transport signals to the one or more DAUs.

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 to at least one of the plurality of BTSs and operable to route signals optically to the one or more DAUs; and   a plurality of digital remote units (DRUs) located at a location remote to the one or more DAUs, wherein the plurality of remote DRUs are operable to transport signals to the one or more DAUs.
