What is Wireless LANWhat is Wireless LAN

A wireless LAN links network users to LAN services A wireless LAN links network users to LAN services without the use of a cabledwithout the use of a cabled connection to attach them connection to attach them to the network infrastructure. In most companies it to the network infrastructure. In most companies it acts as an extension of a wired network, but in smaller acts as an extension of a wired network, but in smaller businesses or hard-to-wire areas it may be the only businesses or hard-to-wire areas it may be the only LAN connection for the user.
