USER GUIDE – Confidea G3 18
When using manual frequency selection in 5 GHz band , ideally the frequency selection is done in
such way that between 2 used frequencies , there is a 40 MHz “distance” to avoid interference by RF
sidebands.
4.2.2. How to avoid interference
The transmission mode between WDUs and WCAP is specifically designed to be used in very
challenging environments with a high density of Wi-Fi signals that are present due to Wi-Fi access
points as well as smart devices , which may cause RF interferences
Wi-Fi devices such as smartphones , tablets, etc., can send regular probing signals over the entire Wi-
Fi band to search for a Wi-Fi connection. This probing can cause temporary interference and will
continue until a Wi-Fi connection is established. When a large number of Wi-Fi devices is present in
the room , these probing signals may cause WDU connection loss due to the saturation of the used
frequency .
Therefore it is strongly recommended that a Wi-Fi collection point is set up, so Wi-Fi devices can lock
on to them and reduce the risk of interference.
Note : The Wi-Fi access points must have sufficient capacity to ensure Wi-Fi connection for all
Wi-Fi devices present. If Wi-Fi connection capacity is insufficient for all mobile Wi-Fi devices
present, then unstable functionality of the Confidea wireless system due to interference cannot be
excluded!
