Abstract:
Apparatus for maintaining a record of radio signal strength for a plurality of channels in a wireless communication system, the apparatus having:measuring means for detecting the radio signal strength on each channel; storage means for storing information relating to the detected signal strengths, wherein the information is stored in the storage means in the form of a value for each channel, each value being representative of the respective detected signal strength on a channel, and the storage means includes an array, with the values being stored in positions in the array such that each position in the array is assigned to a particular channel; and processor means for identifying a first channel carrying a highest signal strength of said detected signal strengths, determining whether a signal having said highest signal strength is transmitted from a first fixed device that is accessible by setting up a synchronization bearer on said first channel, and selecting a second channel of said plurality of channels having a lowest signal strength of said detected signal strengths for communication with said first fixed device when said first fixed device is accessible.
