A base station (12) according to an implementation of the invention is adapted to identify a public power supply frequency, e.g., 50 Hz or 60 Hz. The base station (12) then adapts its frame and slot structures to the power supply frequency. The base station (12) transmits a synchronization word on a data channel, and also transmits a signal indicative of the power supply frequency. The mobile unit (14, 16) receives the data channel and the information indicative of the frequency. The mobile unit (14, 16) then adapts its frame and slot structure appropriately. After the link is established, and if periodic interference is detected, transmission occurs during the inactive period of the interference.
