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.
Claims21
A beacon circuit for use with electronic locks, the beacon circuit comprising:
- a transmitter;
- wherein the beacon circuit is configured to repetitively transmit a beacon signal to initiate subsequent communication with a receiver;
- wherein the beacon signal employs a communication channel which consumes less power than a communication channel for the subsequent communication and wherein the beacon signal comprises an indication of time of the subsequent communication and a slot rate for the subsequent communication, the slot rate defining a periodicity for the subsequent communication;
- wherein the beacon signal comprises sufficient power to activate the receiver;
- wherein the beacon circuit forms part of a key device, and the receiver forms part of an access control device.
A method for providing a beacon signal, the method being performed by a beacon circuit, the method comprising:
- repetitively transmitting a beacon signal to initiate subsequent communication with a receiver;
- wherein the beacon signal employs a communication channel which consumes less power than a communication channel for the subsequent communication and wherein the beacon signal comprises an indication of time of the subsequent communication and a slot rate for the subsequent communication, the slot rate defining a periodicity for the subsequent communication;
- wherein the beacon signal comprises sufficient power to activate the receiver;
- wherein the beacon circuit forms part of a key device, and the receiver forms part of an access control device.
