Wireless System Layout Hints:
•
Avoid locating transmitters and receivers on the same wall.
•
Avoid locating transmitters and receivers where the telegrams must penetrate walls at acute
angles. This increases the material the telegram must pass through reducing the signal
power.
•
Avoid large metal obstructions as they create radio shadows. Place receivers in alternate
locations to avoid the shadow or use repeaters to go around the obstacle.
•
Do not locate receivers close to other high frequency transmitters. Leave at least 3' (1 m)
between the receiver and any other source of interference including, ballasts, LED drivers,
computers, video equipment, Wi-Fi/LAN routers, GSM modems and monitors. Transmitters
are not affected by these sources of interference.
