Wireless Local Area Network (WLAN)
A 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
