WiMAX Forum logo WiMAX base station equipment with a sector antenna and wireless modem on top. Worldwide Interoperability for Microwave Access (WiMAX) is a family of wireless broadband communication standards based on the IEEE 802.16 set of standards, which provide physical layer (PHY) and media access control (MAC) options.
[39] [40] Operates near-blanket coverage across Sydney, Melbourne, Brisbane, Gold Coast, Adelaide and Perth. This network provides Australian businesses with symmetric broadband services. AzQTel Azerbaijan: 3,5 IEEE 802.16e September 2008 [41] Go Broadband Bangladesh: 3,5 IEEE 802.16e April 2014
The Workgroup is a unit of the IEEE 802 local area network and metropolitan area network standards committee. Although the 802.16 family of standards is officially called WirelessMAN in IEEE, it has been commercialized under the name "WiMAX" (from "Worldwide Interoperability for Microwave Access") by the WiMAX Forum industry alliance. The Forum ...
WiMAX is designed to implement a metropolitan area network (MAN) while 802.11 is designed to implement a wireless local area network (LAN). [ citation needed ] However, the use of cellular networks is expensive for the consumers, as they are often on limited data plans .
For wider area communications, wireless local area network (WLAN) is used. WLANs are often known by their commercial product name Wi-Fi. These systems are used to provide wireless access to other systems on the local network such as other computers, shared printers, and other such devices or even the internet.
The coverage of one or more interconnected access points can extend from an area as small as a few rooms to as large as many square kilometres. Coverage in the larger area may require a group of access points with overlapping coverage. For example, public outdoor Wi-Fi technology has been used successfully in wireless mesh networks in London.
A global area network (GAN) is a network used for supporting mobile across an arbitrary number of wireless LANs, satellite coverage areas, etc. The key challenge in mobile communications is handing off user communications from one local coverage area to the next. In IEEE Project 802, this involves a succession of terrestrial wireless LANs. [14]
A nationwide WiMAX network was built in the United States by Clearwire, a subsidiary of Sprint-Nextel, covering 130 million points of presence (PoPs) by mid-2012. [26] Sprint subsequently announced plans to deploy LTE (the cellular 4G standard) covering 31 cities by mid-2013 [27] and to shut down its WiMAX network by the end of 2015. [28]
