Wireless Local Area Networks (WLAN) 1 2 3 1 Router 2 Modem 3 Internet A wireless local area network (WLAN) connects two or more computers with each other and the Internet over the air waves rather than through a network cable connected to each computer. In a WLAN, a radio communications device (an access point or wireless router) connects the networked computers and peripherals, 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.
