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.
What You Need to Establish a WLAN Connection
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
