Various influences can lead to bad performance of the Klick & Show system. A careful frequency planning can
avoid interferences with other electronic devices. A Wi-Fi analyzer is an embedded application tool in Klick &
Show, to provide an advice for the deployment and Wi-Fi configuration.
Klick & Show TOUCH supports 2.4 GHz- and 5 GHz-band. The 2,4 GHz-band has a greater range; the 5 GHz-band
is less sensitives to interferences.
At 5 GHz band, you can choose the channels 36, 40, 44, und 48 ...
At 2,4 GHz you can select the channels 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, and 11.
Default for Klick & Show is 5 GHz, channel 40. The 5 GHz band should be preferred.
Find the optimal Wi-Fi channel
Wireless communication signals travel over the air. Therefore, two devices transmitting at the same time, on the
same frequency, and within range of one another, will disturb each other. This causes a decrease in the actual
data rate achieved between the transmitting and the receiving Wi-Fi devices. The built-in Wi-Fi analyzer tool
helps for the configuration.
Analyze of the installation location
A WiFi scan shows all WiFis in area of Klick & Show. Based on the data of the scan, you can find the least
occupied channel for each meeting room.
The analyzer works in two modes:
-
Simple mode: you can analyze, which channels are suggested (unused channels have a high number of
stars).
-
Expert mode: check received WiFi-spectrum and signal-strength (RSSi).
Based on the results from the site survey, the least occupied channel can be found and selected for each meeting
room.
General rules for WiFi-networks
In case no site survey can be made, the following rules of thumb should allow for a correct configuration:
The Klick & Show access point in a particular meeting room should not re-use a Wi-Fi channel that
