Wireless Local Area Network
A wireless local area network (WLAN) is a series of interconnected computers that communicate with
each other over the air waves rather than through a network cable connected to each computer. In a
WLAN, a radio communications device called an access point or wireless router connects network
computers and provides Internet, or network, access. The access point or wireless router and the wireless
network card in the computer communicate by broadcasting data from their antennas over the air waves.

Before you can set up a WLAN, you need:
High-speed (broadband) Internet access (such as cable or DSL)
A broadband modem that is connected and working
A wireless router or access point
