You cannot discuss any kind of networking in todays IT community without including wireless LANs (WLAN). Few today have not encountered some type of wireless LAN: in the office, the airport and their local Starbucks or favorite bookstore. Wireless LANs are inexpensive to setup when compared with the cost of a physical wired network, considering cost of cable, working within the walls, labor charges and any permits required to run cable.
