simultaneously with the multiple channel wireless transceiver without air
time. The proximity unit validation assembly communicates with the
multiple channel wireless transceiver and receives and validates the
plurality of request authorization codes received by the multiple channel
wireless transceiver. The legacy activation unit receives a service
