12.5 Best Practices for Wireless Communication

Wireless communication is susceptible to interference, distance, walls, and metal barriers. We recommend the following

best practices for trouble-free wireless communication.

1. Electro-Magnetic Interference (EMI): Keep the console several feet away from computer monitors and TVs.

2. Radio Frequency Interference (RFI): If you have other 915 MHz devices and communication is intermittent,

try turning off these other devices for troubleshooting purposes. You may need to relocate the transmitters or

receivers to avoid intermittent communication.

3. Line of Sight Rating: This device is rated at 300 feet line of sight (no interference, barriers, or walls), but

typically you will get 100 feet maximum. [This is under most real-world installations, which include passing

through barriers or walls].

4. Metal Barriers: Radio frequency will not pass through metal barriers, such as aluminum siding. If you have

metal siding, align the remote and console through a window to get a clear line of sight.

The following is a table of reception loss, versus the transmission medium. Each "wall" or obstruction decreases the

transmission range by the factor shown below:

Glass (Untreated)

Plastic

Wood

Brick

Concrete

Metal
