Abstract
Described are a method, a device, and a system managing power usage. The method includes operating a communication device in a first state, transmitting a forward signal to at least one target, switching from the first state to a second state, and receiving a reverse signal from the at least one target while operating in the second state. The device, operating in at least a first state and a second state, includes a control circuit switching the device from the first state to the second state, an amplifier operating at a current level coordinated with one of the first state and the second state, and an antenna transmitting a forward signal to at least one target while the device operates in the first state and receiving a reverse signal from the at least one target while the device operates in the second state.
