Basic rules to set up the WLAN of Klick & Show
Ask your IT department for help when planning larger installations, possibly even on different floors.
Most devices are in the 2.4 GHz band. To prevent devices from interfering with each other in one place, you
should avoid a frequency range that is 3 or more channels higher. Recommended are the channels 1, 6 and 11 if
you want to use the 2.4 GHz band, there are the fewest overlapping.
Note: If quality issues suddenly arise after a successful setup, it may also be that new wireless networks have been
set up, or existing routers have switched to new wireless channels that overlap with Klick & Show Wi-Fi.
It would be possible to choose the same channels. Which results in lower throughput (quality) when multiple
users simultaneously participate and stream videos. Sharing documents is less critical.
The use of a 5 GHz channel is recommended
Do not remove the antennas from the base unit. However, it is possible to find a better place for reception
through an antenna extension cable, e.g. outside a rack.
Undisturbed propagation oft he Wi-Fi can be achieved with a line of sight between the TOUCH sensor button
and the base unit, with as few obstacles as possible to attenuate radio waves. Avoid placing transmitter and
receiver where metal or other dense materials may be present.
The measurement of the signal strength RSSi may e.g. with a smartphone and a free Wi-Fi analysis program, such
as the Android application "Wi-Fi Analyzer" or with another Klick & Show device. At least a signal strength of
RSSi = -70 dBm should be displayed at the location of the base unit (-60 dBm, for example, would be a stronger
signal).
Even if the selected channel is free from other Wi-Fi transmitters, a too weak signal from the TOUCH sensor
button (or from mobile devices) can cause interference.
The field strength should be more than -70 dBm.
If the measured RSSi value is too low, mind the above points for optimization.
