摘要： Systems and methods are provided for automatically detecting passive components in communications systems using radio frequency identification ("RFID") tags. A coupling circuit is provided in a system between a communications network and an RFID tag. The RFID tag is associated with a passive element of a distributed antenna system ("DAS"). The coupling circuit can allow an RFID signal received from an RFID transmitter over the communications network to be transported to the RFID tag. The coupling circuit can substantially prevent mobile communication signals on the communications network from being transported to the RFID tag.

摘要： A base station router for use within an analog distributed antenna system is provided. The base station router comprises circuitry configured to: receive digital signals representing radio frequency channels from at least one base station; convert the digital signals to analog radio frequency signals; communicate analog signals derived from the analog radio frequency signals to a plurality of remote antenna units of the analog distributed antenna system using analog communication links, the analog signals used for transmission of the analog radio frequency signals at each of a plurality of coverage zones at an antenna associated with each remote antenna unit of the plurality of remote antenna units; and distribute capacity between the plurality of coverage zones by changing which sectors received from the at least one base station are provided to which coverage zones.

摘要： A distributed antenna system 50 is provided for communicating with a plurality of base stations 24. The distributed antenna system 50 includes a system controller 52 and a master unit 42 communicating with at least one of the plurality of base stations 24. A remote unit 44 communicates over a high data rate media with the master unit 42 and/or a downstream remote unit 44. Alternatively, the distributed antenna system 50 includes a controller 52 and a digital time/space crosspoint switch 302 controlled by the controller 52. A digitizing transceiver 306 is in communication with the digital time/space crosspoint switch 302. The crosspoint switch 302 is configured to transmit and receive digital data through the digitizing transceiver 306.
