FREQUENCIES

Radio network cards and adapters are designed in accordance with
IEEE-Standard 802.11b+g for use in the ISM frequency band (Industrial,
Scientific, Medical) between 2.4 and 2.4835 GHz. Because of the DSSS-
procedure (Direct Sequence Spread Spectrum), each of the 11 usable
radio channels takes up a width of 22 MHz; this means that up to three,
independent channels are available (e.g. 3, 8 and 11). The following table
lists the authorised channels in your country:
