摘要: A method of communicating between electronic door locks (12), access point hubs (14) and a central controller (22) includes the steps transmitting probe signal from or hub receiver (16) to electric lock (12) in several different frequencies. Transmission stations are then synchronized accommodate multiple prevent overlapping transmissions.
