WiMAX is a wireless digital communications system, also known as IEEE 802.16 that is intended for wireless "Metropolitan area networks". WiMAX can provide broadband wireless access up 50km for fixed stations and 5-15km for mobile stations. In contrast, the Wi-Fi 802.11 wireless local area network standard is limited in most cases to only 30 - 100m. It is also known as 802.16 networking or wireless networking. The new area of communication, currently employed in some parts of the world is Worldwide interoperability for Microwave Access (WiMAX). It is the latest technology which is approved by IEEE 802.16 group, which is a standard for point-to-multipoint wireless networking.
