    <title>Introduction to Wireless Tools</title>

    <para>The Wireless Extension (WE) is a generic API in the Linux kernel
    allowing a driver to expose configuration and statistics specific to common
    Wireless LANs to user space. A single set of tools can support all the
    variations of Wireless LANs, regardless of their type as long as the
    driver supports Wireless Extensions. WE parameters may also be changed on
    the fly without restarting the driver (or Linux).</para>

    <para>The <application>Wireless Tools</application> (WT) package is a set
    of tools allowing  manipulation of the Wireless Extensions. They use a
    textual interface to support the full Wireless Extension.</para>

    <para>To use <application>Wireless Tools</application>, the kernel must
    have the appropriate drivers and other support available.  The appropriate
    bus must also be available.  For many laptops, the PCMCIA bus
    (CONFIG_PCCARD) needs to be built.  In some cases, this bus support will
    also need to be built for embedded wireless cards.  The appropriate bridge
    support also needs to be built.  For many modern laptops, the CardBus host
    bridge (CONFIG_YENTA) will be needed.</para>

    <para>In addition to the bus, the actual driver for the specific wireless
    card must also be available.  There are many wireless cards and they don't
    all work with Linux.  The first place to look for card support is the kernel.
    The drivers are located in Device Drivers &rarr; Network Device Support
    &rarr; Wireless LAN (non-hamradio).  There are also external drivers
    available for some very common cards.  For more information, look 
    at the user notes.</para> 

    <para>After the correct drivers are loaded, the interface will 
    appear in <filename>/proc/net/wireless</filename>.</para>
