WLAN stands for Wireless Local Area Network. It is a system of LANs (multiple Local Area Networks) connected over a specific area by telephone lines and radio waves. Because WLANs transmit and receive data over the air (via radio frequency technology), the need for cable/wired connections is minimized. The area covered by a WLAN is limited. A WLAN does not need wired Ethernet connections. The WLAN can either be an extension to a current network or as an alternative to the current network.

As long as users stay within the WLAN’s access points, they can move between and within the coverage area without experiencing disruption.

Typical data transfer speeds for WLAN range from 1 to 54mbps. The 802.11n standard can reach 300 to 600Mbps.

Range for a WLAN is within 65 to 300 feet.

WLANs can be either indoor or out.
