According to the Intel website
"What is Wireless LAN Networking?
A Wireless Local Area Network (WLAN) is a flexible data communications system that can either replace or extend a wired LAN to provide added functionality. A traditional, wired local area network (LAN) sends packets of data from one piece of equipment to another across cables or wires. A wireless local area network (WLAN) relies instead upon radio waves to transfer data. Data is superimposed onto a radio wave through a process called modulation, and this carrier wave then acts as the transmission medium, taking the place of a wire."
Seem familiar to anyone?
