With the advent of wide area trunked systems, the number of frequencies a subscriber unit must maintain has increased significantly. To circumvent this problem, possible solutions include the following: * Frequency reuse is employed between sites and a wide area trunked system is meticulously con- structed such that as few as possible frequencies are allocated for control channel use while pre- venting interference among sites, . Status information about adjacent sites and their respective frequencies are broadcast out at each site and tracked by the subscriber unit.
