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 2.485
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. , 8 and 11). The following table lists the authorised channels
in your country:
