Abstract: A repeater system is provided, the repeater system comprising a front end section and a back end section for providing communication between communication sources and a coverage area. The front end section combines multiple downlink signals from multiple communication sources into a combined downlink signal and transmits the combined downlink signal to the back end section.

The back end section also produces, from a received uplink RF communication signal, an uplink combined signal. The front end section produces multiple signals from the uplink combined signal received from the back end section for transmission to the communication sources. By these means a repeater system is provided which may provide an approved coverage in a coverage area with the potential of high data rates for communication links in that coverage area.

Abstract: 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.
