<p>A cordless telephone (8) has an improved mechanism for scanning and selecting channels by adapting to the channel usage patterns of the local environment having a plurality of channels available for usage. A prioritized list of channels (120) having the highest probability of being interference free is produced. The channels are prescanned during idle time, so quick acquisition of an available channel is possible. Accordingly to another feature, a scan subset comprising a first group of clear channels is selected upon system powerup. The available channels are scanned during the idle time to select a preferred channel subset which comprises channels which are the most interference free.</p> |
