摘要： A mobile testing system for optimizing wireless coverage in a distributed antenna system is disclosed. In some aspects, the mobile testing system includes a measurement receiver that can determine signal levels for a respective signals communicated via the distributed antenna system. A processing device of the mobile testing system can identify a subset of the signals by decoding a respective identifier encoded in each of the subset of signals. The identifiers specify that the subset of signals is targeted to at least one coverage zone in which the mobile testing system is located. A subset of signal levels is obtained by the measurement receiver that corresponds to each of the subset of signals. The processing device can generate coverage contour data based on the subset of signal levels that describes signal coverage for at least one coverage zone.

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： A switching control module can optimize time division duplexing operations of a distributed antenna system ("DAS"). The switching control module can include a measurement receiver and a processor. The measurement receiver can measure signal powers of downlink signals in a downlink path of the DAS. The processor can determine start times for downlink sub-frames transmitted via the downlink path based on downlink signal powers measured by the measurement receiver exceeding a threshold signal power. The processor can identify a clock setting that controls a timing of switching signals used for switching the DAS between an uplink mode and a downlink mode. The processor can statistically determine a switching time adjustment for the clock setting based on switching time differentials between the clock setting and the start times. The processor can update the clock setting based on the switching time adjustment.
