ABSTRACT:
A communications system, such as the DECT, comprises a plurality of geographically separate primary stations and a plurality of secondary stations which are able to roam relative to the primary stations. Communication between a primary and a secondary station is by way of any of a plurality of time division duplex radio channels. An idle primary station transmits an idle beacon signal. When a secondary station roams out of the coverage area of a primary station and so can longer lock to that primary station, it scans all of the radio channels for an idle beacon signal. To conserve battery power, instead of continuously rescanning all channels, the successive rescans are made less frequently as the time interval from when the secondary station was last in lock increases, until a predetermined maximum interval has been reached between successive rescans.
