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 "Toussaint OTTAVI (TK1BI)" wrote: > > Hi list, > > A few days ago, I saw a message about configuring a 802.11b network > adapter under Linux. > > For those who don't know, 802.11b (also called 'WiFi') is a wireless lan > protocol, to connect 'remote' computers to Ethernet networks via a > radio link. 802.11b equipments (network adapters, access points, bridges) > are becoming more and more popular, and prices are very affordable. > > These equipments are using freqencies over 2400 MHz.
