Patent ID: 8180291

Claim:
An apparatus comprising: wireless transceiver circuitry to provide IEEE 802-compliant wireless communication for an electronic device; and a power-scavenging receiver coupled with the wireless transceiver circuitry to invoke a pre-selected signal to cause the wireless transceiver circuitry to change operational state in response to a signal received by the power-scavenging receiver, wherein the power-scavenging receiver causes the wireless transceiver circuitry to transition to a low-power state when exiting an environment in which selected wireless communications are enabled as detected by the power-scavenging receiver and causes the wireless transceiver circuitry to transition out of a low-power state and begin a discovery protocol for identifying network access points when entering the environment as detected by the power-scavenging receiver, the power-scavenging receiver receives an indication of wireless frequencies that are authorized for communication, and wireless frequencies that are not authorized, further wherein the signal from the power-scavenging receiver does not cause a change in operational state for components of the apparatus other than the wireless transceiver, the environment defined by a plurality of readers to communicate with the power-scavenging receiver.
