Abstract:
1. A method of reducing interference between radio frequency (RF) signals, said method comprising: initiating a first communication session from a control system to a remote RF device using a first RF signal to transmit a first outgoing message to the remote RF device, the first RF signal within a first RF range; detecting, at the control system, a second communication session transmitted from a system RF device to the control system using a second RF signal, the second communication session including an incoming message from the system RF device, the second RF signal within a second RF range at least partially overlapping the first RF range; when the second communication session IS detected, interrupting the first communication session for a predetermined time period; receiving the second communication session during the predetermined time period to receive the incoming message from the system RF device; and after the predetermined time period expires, resuming the first communication session with the remote RF device.
