A wireless communication device is disclosed that is capable of utilizing bandwidth outside of its allocated bandwidth in order to maximize frequency coverage. The allocated band is separate from a neighboring band by a guard band. The device performs a scan of the neighboring band in order to determine an activity level within the neighboring band. Based on the determined activity level, the device expands its communication frequency range to include the guard band and/or the neighboring band. Once expanded, the device periodically rescans the neighboring band in order to determine whether the device must contract its frequency band out of the expanded area. The device can also receive activity level information of the neighboring band from a server via a common network infrastructure, and can coordinate expansion with other devices.
