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’ between the receiver and any other source of interference 

including, ballasts, LED drivers, computers, video equipment, Wi-Fi/LAN 

routers, GSM modems and monitors.
