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 .mu.A while actively
awaiting and screening for a targeted broadcast.
