Classically designed with high-speed mobile browsing, email, multimedia features, a multitude of connectivity options, and convenient shortcut keys.

Wireless LAN. It is a local area network that transmits over the air typically in an unlicensed frequency such as the 2.4GHz band. A wireless LAN does not require lining up devices for line-of-sight transmission like IrDA. Wireless access points (base stations) are connected to an Ethernet hub or server and transmit a radio frequency over an area of several hundred to a thousand feet and can penetrate walls and other nonmetal barriers. Roaming users can be handed off from one access point to another like a cellular phone system. Laptops use wireless modems that plug into an existing Ethernet port or that are self contained on PC cards, while standalone desktops and servers use plug-in cards.
