摘要： A distributed antenna system includes a plurality of remote antenna units with a passive element coupled to at least one of the remote antenna units at a connection juncture. An RFID system is associated with the first passive element and has RFID data identifying the first passive element. An interrogator unit is associated with the remote antenna unit and is configured for generating a least one signal for transmission to the passive element to be reflected at the connection juncture and received at the interrogator unit. The interrogator unit is also configured for generating at least one signal for transmission to the RFID system to obtain the RFID data identifying the passive element. Processing circuitry processes the reflected signal and measures a parameter of the first passive element. The processing circuitry correlates the measured parameter with the RFID data for the passive element.

摘要： Certain features relate to a telecommunications system with a modular frequency combiner combining multiple received signals at different frequency bands without using frequency-dependent multiplexers. The frequency combiner can include adjustable tuning elements for adjusting various signal-processing parameters of the frequency combiner while the frequency combiner is in the telecommunications system. For example, adjustable tuning elements can adjust the phases of phase shifters of each RF path so that the RF paths are matched for combining the received signals and outputting them through an output port. The adjustable tuning elements can also adjust the electrical length or physical length of the transmission lines that carry the received signals. The adjustable tuning elements can be adjusted manually or automatically while the frequency combiner is deployed in the field in the telecommunications system.

摘要： Uplink leveling systems and methods for a distribution antenna are provided. An uplink leveling system includes at least one communication path between a base station point of interface and a remote antenna unit. A broadband measurement detector is communicatively coupled to measure signal power in the at least one communication path at the base station point of interface. A signal measurement receiver is communicatively coupled to measure signal power in the at least one communication path. A test signal generator is configured to generate a test signal in the at least one communication path in an uplink. At least one controller is configured to level the communication path in the uplink direction based at least in part on measurements by the broadband measurement detector and the signal measurement receiver in response to the generated test signal by the test signal generator.
