DAS integrated digital off-air repeater

摘要

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.

主权项

1. A distributed antenna system, comprising:
a repeater operable to exchange radiofrequency signals over the air with at least one remotely located Base Transceiver Station (BTS), wherein the repeater is configured to convert between analog signals and digital signals; a Digital Access Unit (DAU) communicatively coupled with the repeater, wherein the DAU is operable to exchange digital signals with the repeater; a plurality of Digital Remote Units (DRUs), each located at different locations than the repeater, wherein each DRU from the plurality of DRUs is communicatively coupled with the DAU and is operable to exchange digital signals with the DAU; wherein the DAU is operable to route communications between the repeater and at least one DRU from the plurality of DRUs.
