Abstract (en)

[origin: WO03098851A1] A wireless transceiver (5008) includes a low power radio frequency (LPRF) component (5010) that powers down to conserve energy and powers up in response to a signal; and a second receiver (5014) that provides the signal via line (5018) in response to receipt of a radio frequency broadcast. The broadcast is targeted to activate particular transceivers by including in the broadcast identifications such as class designations, in which case the transceivers power up and form networks. A transceiver may include one or more identifications and may include a unique identification of the transceiver itself. The LPRF component is a Bluetooth radio, but the overall transceiver itself only draws about 10 to 15µA while actively awaiting and screening for a targeted broadcast.
