Glossary Detail WLAN
Wireless Local Area Network

The wireless version of a LAN (local-area network). WLAN technology provides short-range, high-speed wireless data connections between mobile data devices (such as laptops, PDAs, and phones) and nearby Wi-Fi access points (special hardware connected to a wired network).

WLAN technology is generally faster than 3G mobile technologies, but with much shorter range. 3G is therefore in a category known as WWAN (Wireless Wide-Area Network).

Wi-Fi, or 802.11, is the most common WLAN technology.
