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 ...
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.
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. [15]
The group also decided to implement mobility by considering access points in the infrastructure and mobile users in the service area as inputs and outputs of a distributed multiple-input multiple-output (D-MIMO) link. 802.15.13 supports D-MIMO natively with a minimalistic design, suitable for specialty applications.
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 .
However, in December 2010, the ITU expanded its definition of 4G to include Long Term Evolution (LTE), Worldwide Interoperability for Microwave Access (WiMAX), and Evolved High Speed Packet Access (HSPA+). [2] The first-release WiMAX standard was commercially deployed in South Korea in 2006 and has since been deployed in most parts of the world.
