Abstract
A wireless communication system implements various RFID-based methods for wireless communication devices and wireless network infrastructures. The communication system includes an RFID tag and a wireless communication device. The RFID tag is configured to receive an RFID interrogation signal and, upon receipt thereof, to supply one or more transition signals. The wireless communication device is configured to operate in a plurality of operational states, is coupled to receive the transition signals, and is configured, upon receipt thereof, to transition from at least a first operational state to a second operational state.
