from the appropriate authorities in your country (e.g. www.regtp.de).
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:
