8.2 Stegos and WLAN or WiFi
Like WLAN, the Stegos system uses the same bandwidth of approx. 22 MHz for each RF channel (Low,
Mid, High). This results in three compatible RF channels in the 2.4 GHz-ISM band. These are theoretically:
Compatible channel 1: 2400 MHz - 2428 MHz (theoretical mid frequency: 2414 MHz)
Compatible channel 2: 2428 MHz - 2456 MHz (theoretical mid frequency: 2442 MHz)
Compatible channel 3: 2456 MHz - 2484 MHz (theoretical mid frequency: 2470 MHz)
The Stegos system uses RF channels (Low, Mid, High) compatible to each other. For WLAN the user has
to configure compatible RF channels.

You can easily recognise that the individual WLAN channels overlap considerably due to their band-
width. All neighbouring channels (e.g. channel 1 & 2 or channel 7 & 8) cannot be used simultaneously,
because they would disturb each other. Furthermore, channel 12 and 13 are not approved for the use
in the USA. In general, these channels are not used either. Within the remaining frequency bands only
the WLAN channels 1, 6 and 11 can be used simultaneously.
