A single transmitter (109) controlled to transmit at appropriate beacon signal frequencies (F1-F3) is scanned through each of the frequencies (F1-F3) so that a mobile station (101) can determine when a hard handoff to different frequencies (F4-F6) is required. The beacon signal transmitter (109) is controlled by a controller (112) to transmit beacon signals which include a pilot channel only, pilot/sync channels, pilot/page/sync channels common to each of the frequencies (F1-F3), or pilot/page/sync channels different for each of the frequencies (F1-F3). Additional control is provided by the controller (112) such that each of frequencies (F1-F3) is further transmitted to different sectors (A1-A3) when the coverage area supported by a target base-station (106) is sectorized.
