FREQUENCIES
Radio network cards and adapters are designed in accordance with IEEE-Standard 802.11b+g
(+n, optional) 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:
Channel MHz Europe, R&TTE France, R&TTE
