Abstract
A wireless transceiver includes: (a) a low power radio frequency (LPRF) communications component capable of powering down to conserve energy and capable of powering up in response to an electronic signal, the LPRF communications component including a transmitter and a first receiver; and (b) a second receiver that is configured to screen a radio frequency broadcast and provide, on the basis of specific data identified therein, the electronic signal to the LPRF communications component in order to power up the LPRF communications component. The second receiver is adapted to draw less current than the LPRF communications component while awaiting receipt of and listening for a radio frequency broadcast.
