    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. The exact
    frequency coverage depends on country regulations, ie in France, only
    4 channels are allowed, around 2450 to 2480 (not sure about the exact
    values). Maximum throughput is 11 Mbits with high efficiency modulation
    techniques.

    PURPOSE:
    --------

    Does someone think it would be technically possible to modify the
    radio part of such a network adapter, in order to work on the amateur
    radio 2.4 GHz frequencies (2350-2400) ?

    I presume this is not so easy ;-) This would anyway allow great
    capabilities for high rate TCP/IP packet-radio links for affordable
    prices.

    Could some specialists of SHF and/or digital modulation techniques give
    us their point of view about the feasibility of such modifications on
    commercial 802.11b equipments ?

    (sorry for my poor english which may be inaccurate ;-)

    Thanks for comments & best 73,
    Toussaint.
