Re: 802.11b wireless lan equipment and ham radio ?

Hi, Toussaint:

 Yes, maybe. ;-)

It is exciting to have 11 megabit data radios for $80 - $120 US !

 In the USA, the Amateur band segment is 2390-2450.
In the 802.11b cards sold in/for USA, channels
1 through 6 fall within that Amateur Radio segment.

 Perhaps there are some Amateur Radio operators
working for an 802.11b manufacturer that would create
firmware data that could be flashed into the card(s) that
would put them inside the Amateur Radio bands of all/any
countries with 2.4 GHz emission authorizations.

OBTW, Isn't 2.4 GHz UHF, rather than SHF? ;-)

Station ID via the 'Pattern function of 'ping':
ping -f -i 600 -p <## ## ## ## ## ## ## ## ## ##>
                   20 44 45 20 4E 43 38 51 20 20
                       D  E     N  C  8  Q

HTH, Chuck
