Manufacture of LPRF device wake up using wireless tag
First Claim
1. A method of manufacturing a wireless transceiver that can be used to read one or more wireless tags (WTs) that are disposed externally to and in proximity of the wireless transceiver (WRT), the method comprising the step of hardwiring within a housing of the WRT:
- (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 providing in response to receipt by the second receiver of a radio frequency broadcast the electronic signal in order to power up the LPRF communications component.

Abstract
A method is disclosed for manufacturing a wireless transceiver (5008) having 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 15 μA while actively awaiting and screening for a targeted broadcast.
