A method for maintaining a communication link in wireless network groups

Disclosed herein is a method and apparatus for maintaining communication between a dependent and a communications network when the dependent is outside a coverage area associated with its master using a controller and a communications network. In one embodiment, when the dependent is in a piconet, the dependent is within communication range of its master using a communication channel on frequency band fband(1). When the dependent moves outside the piconet, the dependent should be within communication range of the controller and, thus, switches to another communication channel within frequency band fband(1) such that it may communicate with the controller. When the dependent moves outside the communication range of the controller, the dependent should be within communication range of a communications network or a base station and, thus, switches to a communication channel within another frequency band fband(2).
