Why a wireless LAN?
The greatest advantage of wireless networking is mobility: people move, networks do not. Wireless users can connect to existing networks and access data (usually stored centrally) while they are in motion. From this point of view, a wireless network can be very useful, especially for people coming to CERN on a temporary basis, like a conference, or people wandering around the laboratory for work reasons: they can access the network and work on line all the time just by bringing their own laptop with a wireless card in it.
