Abstract

A cordless telephone has an improved mechanism for scanning and selecting channels by adapting to the channel usage patterns of the local environment in which it is placed. This results in a prioritized list of channels that have the highest probability of being available, free from interference. By prescanning the channels during the idle time of the cordless telephone, power usage of the handset is minimized and quick acquisition of an available channel becomes possible.
