Abstract
It is provided a beacon circuit for use with electronic locks. The beacon circuit comprises a transmitter. The beacon device is configured to repetitively transmit a beacon signal to initiate subsequent communication with a receiver. The energy use for the beacon signal employs a communication channel which consumes less power than a communication channel for the subsequent communication. The beacon signal comprises an indication of time of the subsequent communication.
