4.3 Best Practices for Wireless Communication
Wireless communication is susceptible to other interference,
such as distance, walls and metal barriers. We recommend the
following best and useful 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
433 MHz devices and communication is intermittent, try turning
off these other devices for troubleshooting purposes. You may
need to relocate the wireless transmitters or receivers to avoid
intermittent communication.
3. Line of Sight Rating. This device is rated at 300ft line of
sight (no interference, barriers or walls) but typically you will
get 100ft maximum 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 vs. the transmission
medium. Each “wall”or obstruction decreases the transmission
range by the factor shown below.
Medium
RF Signal Strength
Reduction
Glass (untreated) 5-15%
Plastics 10-15%
