Transmission Obstructions and Interference

One way to get around an obstruction, such as a duct, is to place the wireless adapter on the side of the obstruction that is
nearer to the coordinating wireless device, even if the controller is on the opposite side of the obstruction. But always keep
in mind that the wireless adapter performs best when it is away from metal objects or surfaces (more than 1" (2.5 cm)).
For more examples on how to position the wireless adapter, see ECLYPSE Wi-Fi Adapter Mounting Tips.
In addition to obstructions, the angle with which the transmission travels through the obstruction has a major influence on
the field strength. The steeper the angle through an obstruction, the radio wave has to travel through more material result-
ing in the field strength reduction (See figure below). Therefore, it is preferable that the transmission be arranged so that it
travels straight and perpendicularly through the obstruction.

A solution to avoid an obstruction is to add another wireless router located closer to the controller(s).

ECLYPSE Wi-Fi Adapter Mounting Tips

This section provides information and examples on how to properly position the Wi-Fi Adapter to ensure reliable wireless
communication. The most common guidelines to remember when installing the Wi-Fi Adapter is to keep it at least 1" (2.5
cm) away from metal, and never install the Wi-Fi Adapter inside a metal enclosure (relay panels, junction box, etc.).
Typical Metal Relay Panel/Utility Box Installation
The following image shows where to install an Wi-Fi Adapter on a metal relay panel or utility box with a controller inside the
panel/box. To maximize wireless range, the Wi-Fi Adapter must be installed on the top or side of the panel.
