| IEEE 802.16 |
The IEEE 802.16 Working Group on Broadband Wireless Access Standards,
which was established by IEEE Standards Board in 1999, aims to prepare formal
specifications for the global deployment of broadband Wireless Metropolitan
Area Networks. The Workgroup is a unit of the IEEE 802 LAN/MAN Standards
Committee. A related future technology Mobile Broadband Wireless Access
(MBWA) is under development in IEEE 802.20.
Although the 802.16 family of standards is officially called WirelessMAN, it has
been dubbed “WiMAX” (from "Worldwide Interoperability for Microwave Access")
by an industry group called the WiMAX Forum. The mission of the Forum is to
promote and certify compatibility and interoperability of broadband wireless
products.
802.16 standards The first 802.16 standard was approved in December
2001. It delivered a standard for point to multipoint Broadband Wireless
transmission in the 10-66 GHz band, with only a line-of-sight (LOS) capability.
It uses a single carrier (SC) physical (PHY) standard.
802.16a was an amendment to 802.16 and delivered a point to multipoint
capability in the 2-11 GHz band. For this to be of use, it also required a non
line of sight (NLOS) capability, and the PHY standard was therefore extended to
include Orthogonal Frequency Division Multiplex (OFDM) and Orthogonal
Frequency
Division Multiple Access (OFDMA). 802.16a was ratified in January 2003 and
was intended to provide "last mile" fixed broadband access.
802.16c, a further amendment to 802.16, delivered a system profile for the 10-
66 GHz 802.16 standard.
In September 2003, a revision project called 802.16d commenced aiming to
align the standard with aspects of the European Telecommunications Standards
Institute (ETSI) HIPERMAN standard as well as lay down conformance and test
specifications. This project concluded in 2004 with the release of 802.16-2004
and the withdrawal of the earlier 802.16 documents, including the a/b/c
amendments.
An amendment to 802.16-2004, IEEE 802.16e-2005 (formerly known as IEEE
802.16e), addressing mobility, was concluded in 2005. This implemented a
number of enhancements to 802.16-2004, including better support for Quality of
Service and the use of Scalable OFDMA, and is sometimes called “Mobile
WiMAX”, after the WiMAX forum for interoperability.
