A radio local loop (RLL) system which can automatically reallocate fixed subscriber units to a different radio domain without expending the costly and time consuming efforts needed to manually readjust antennas. By transmitting a code to the fixed subscriber unit, whereby the code identifies a second radio domain, an antenna associated with the fixed subscriber unit automatically adjusts such that said subscriber unit can communicate with the second domain using a radio channel. While the scann angle of the antenna is adjusted, the fixed subscriber unit derives a signal quality value for a number of radio channels. Based on the signal quality values, the RLL system determines whether the second radio domain exhibits superior signal quality characteristics as compared to the first radio domain. If the second radio domain exhibits superior signal quality characteristics than the first radio domain, the fixed subscriber unit is reallocated to the second domain. Further, the fixed subscriber unit automatically performs a dynamic channel selection scheme. This scheme allows the fixed subscriber unit to select the available traffic channel that exhibits the best signal quality characteristics for establishing a connection.
