Abstract

A system including a digital appliance having a high data rate wideband RF transceiver operating in a microwave band for communicating digital data within quiescent periods of periodic noise and within quiescent periods within super cycle noise enclosing the periodic noise. The quiescent periods can also be used to control power management of the appliance as well as perform network control.
