Abstract
A method for reducing interference between radio frequency (RF) signals includes 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, wherein the first RF signal within a first RF range, and detecting a second communication session transmitted from a system RF device to the control system using a second RF signal. The second communication session includes an incoming message, and the second RF signal is within a second RF range at least partially overlapping the first RF range. The method includes, when the second communication session is detected, interrupting the first communication session for a time period, receiving the second communication session during the time period to receive the incoming message, and, after the time period expires, resuming the first communication session with the remote RF device.
