A WLAN can be either an extension to a current wired network or an alternative to it. WLANs have data transfer speeds ranging from 1 to 54 Mbps, with some companies offering proprietary 108Mbps solutions. A WLAN signal can be broadcast to cover an area ranging in size from a small office to a large campus. Most commonly, a WLAN access point provides access within a radius of 65 to 300 feet. It should be noted that the IEEE 802.11 are the standards that most of the modern wireless LANs are based on.
