Abstract

A wireless communication system facilitates wireless communication with a subscribing unit operating within a respective service area. At least one base station supports wireless communication within the service area in a plurality of frequency bands and according to a plurality of communication protocols. In a broadcast message, a transmitting base station indicates to the subscribing unit the plurality of frequency bands and the plurality of communication protocols available. The subscribing unit receives the broadcast message and communicates with the base station on one of the plurality of frequency bands according to one of the plurality of communication protocols. In another embodiment, the system includes a plurality of base stations providing overlying coverage within the service area. In such systems, multiple broadcast message may provide information regarding the overlying coverage provided. The broadcast message may also include channel information that indicates the available channels within the available frequency bands, preference information, traffic levels within the frequency bands, available bandwidth within the frequency bands and system operator information tha…
