Remote unit for communicating with base stations and terminal devices

摘要

A remote unit of a distributed antenna system is disclosed that can communicate analog RF signals with both base stations and terminal devices in a coverage zone serviced by the remote unit. In some aspects, the remote unit can include a signal processing module and a transceiver. The transceiver can communicate RF signals between a master unit of the distributed antenna system and a terminal device. The transceiver can also receive analog downlink RF signals from a base station. The signal processing module can convert the analog downlink RF signals to digital downlink signals and provide the digital downlink signals to the master unit.

1. A distributed antenna system comprising:
a master unit; a first remote unit communicatively coupled to the master unit; and a second remote unit communicatively coupled to the master unit; wherein the first remote unit is configured for:
receiving analog downlink RF signals from a base station,converting the analog downlink RF signals to digital downlink signals, andproviding the digital downlink signals to the master unit; wherein the master unit is configured for transmitting the digital downlink signals received from the first remote unit to the second remote unit, wherein the master unit is further configured for instructing the first remote unit to establish a communication link with the base station in response to detecting a malfunction with respect to an additional communication link between the master unit and an additional base station.
