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.

High-speed (broadband) Internet access (such as cable or DSL)
l
A broadband modem that is connected and working
l
A wireless router or access point
l
A wireless network card for each computer that you want to connect to your WLAN
l
Network cable with the network (RJ-45) connector
