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

2.4and 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
1	2412	X
