Directional signal strength

Wireless performance can vary depending on the orientation 
of the advice. Depending on the device, max performance can 
be directional or planar. In the example below, the wireless 
signal is strongest from the front and back of the unit. 

Refer to your device's instruction manual for details on 
directional signal strength.

Strong

Weaker

Strongest

(front)

Directional issues may be noticed with door sensors, for 
example, when the sensor performs differently depending 
on whether the door is open or closed. If communication is 
inconsistent, please add an additional repeater.

Wireless Signal Strength

Signal Range

Wireless signals can refl ect and bounce, but it is best to 
assume that devices will communicate using a direct path.

However, signal range is impacted by sensor orientation, 
obstacles between sensors, and the environment's RF noise.

Repeater

When wireless devices can not be positioned so that the 
direct signal path is within the areas of strong signal strength, 
a repeater may be required to relay the signal.

The repeater should be positioned so that direct signal path 
with each device is within the areas of strong signal.

Nexia devices, including the appliance module, dimmer module, 
and wired thermostat, function as repeaters that can extend the 
the range of wireless signals.
