Abstract
A distributed antenna system comprises a plurality of antennas and a multi-port hub. The multi-port hub comprises an interface to a telecommunications network and a plurality of transceivers. The multi-port hub is configured to operate in a first mode ('normal' mode) in which the multi-port hub receives a downlink communications signal via the interface and distributes the downlink communications signal to the plurality of antennas using a selected downlink transmission frequency within a downlink frequency range and in which the multi-port hub receives uplink communications signals from the plurality of antennas at a selected uplink receive frequency. The multi-port hub is also configured to operate in a second mode ('listening' mode) in which the multi-port hub receives communications signals from the plurality of antennas at one or more frequencies within the downlink frequency range. The transmission frequency for the first mode (“normal” mode) may be selected based on field strength of the signals received in the second mode (“listening” mode).
