Method and systems to facilitate reducing interference between RF signals
First Claim
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.

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.

8. A control system, comprising:
-
a radio frequency (RF) transmitter-receiver module configured to transmit and receive first RF signals within a first RF range, said RF transmitter-receiver module comprising at least one RF transmitter-receiver; an RF receiver module configured to receive second RF signals within a second RF range that at least partially overlaps the first RF range, said RF receiver module comprising at least one RF receiver; and a processor coupled in communication with said RF transmitter-receiver module and said RF receiver module, said processor configured to; engage in a first communication session with a remote RF device using said RF transmitter-receiver module to transmit a first outgoing message within said first RF signals; detect a second communication session with said second RF signals using said RF receiver module, said second RF signals transmitted by a system RF device and comprising an incoming message encoded therein; when said second communication session is detected, interrupt said first communication session for a predetermined time period; receive said second RF signals during said predetermined time period using said RF receiver module; and after said predetermined time period expires, resume said first communication session. - View Dependent Claims (9, 10, 11, 12, 13)
