Configure frequency settings
- Click the menu icon and select Frequency settings.
The left part of the page shows which frequencies are selected (A). The frequency used by the WCAP is indicated in green.
- Select frequencies on the right part of the page (B), this list contains all available frequencies. Select all frequencies in a category by clicking the checkbox next to the title (C) or select separate frequencies (D). Frequencies that are not selected, will not be used.
You can see the strength of the signal by the amount and the colors of the bars next to the frequency (E).
If you select more than one frequency, then the WCAP will automatically select a frequency from the selection.
If more than one WCAP or Wi-Fi access points are in the same room or within 30 m, we advise that only one uses automatic frequency selection. This is to avoid that the frequency scanning is disturbed by the other access point(s). If multiple access points are used within each other’s reach, manual frequency selection based on frequency planning is strongly recommended to avoid that Wi-Fi access points and Confidea WCAP would use the same frequencies.
When the Confidea wireless system is set to manually select the wireless carrier frequency, then you must check that the Confidea wireless carrier does not overlap the already occupied Wi-Fi wireless carrier channels.
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.
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.
