standard. Products that implement 802.11 standards must pass tests and are referred to as "Wi-Fi certified." IEEE 802.11 is a set of

media access control (MAC) and physical layer (PHY) specifications for implementing wireless local area network (WLAN)

traffic over optical fiber ring networks. The standard began development in November 2000 and has undergone several amendments

since its initial standard was completed in June 2004. The amended standards are 802.17a through 802.17d, the last of which was

adopted in May 2011. It is designed to provide the resilience found in SONET/SDH networks (50 ms protection) but, instead of

setting up circuit oriented connections, provides a packet based transmission, in order to increase the efficiency of Ethernet and IP

services. It is hibernating at the moment.

802.18 (Radio Regulatory TAG) IEEE 802.18, the Radio Regulatory Technical Advisory Group ("RR-TAG"), is a working group of IEEE 802, the LAN/MAN

Standards Committee (LMCS). The working group currently has 6 projects on standards for radio-based systems:

● IEEE 802.11 (Wireless Local area network- WLAN)

● IEEE 802.15 (Wireless Personal area network - WPAN)

● IEEE 802.16 (Wireless Metropolitan area network - WMAN)

● IEEE 802.20 (Wireless Mobility)

● IEEE 802.21 (Hand-off/Interoperability Between Networks)

● IEEE 802.22 (Wireless Regional Area Network - WRAN).

802.19(Coexistence TAG) IEEE 802.19 is the Wireless Coexistence Technical Advisory Group (TAG) within the IEEE 802 LAN/MAN Standards Committee.

The TAG deals with coexistence between unlicensed wireless networks.Currently the 802.19 TAG addresses coexistence between

wireless standards under development within IEEE 802.

802.20(Mobile Broadband Wireless Access) IEEE 802.20 or Mobile Broadband Wireless Access (MBWA) is a specification by the standard association of the Institute of

Electrical and Electronics Engineers (IEEE) for mobile wireless Internet access networks. The main standard was published in

2008. MBWA is no longer being actively developed.

This wireless broadband technology is also known and promoted as iBurst (or HC-SDMA, High Capacity Spatial Division Multiple

Access). It was originally developed by ArrayComm and optimizes the use of its bandwidth with the help of smart antennas. Kyocera

is the manufacturer of iBurst devices.

802.21(Media Independent Handoff) 802.21 is an IEEE standard published in 2008. The standard supports algorithms enabling seamless handover between networks of

the same type as well as handover between different network types also called Media independent handover (MIH) or vertical

handover. The standard provides information to allow handing over to and from 802.3, 802.11, 802.15, 802.16, 3GPP and 3GPP2

networks through different handover mechanisms.

The IEEE 802.21 working group started work in March 2004. More than 30 companies have joined the working group. The group

produced a first draft of the standard including the protocol definition in May 2005. The standard was published January 2009.

802.22(Wireless Regional Area Network) IEEE 802.22 WRANs are designed to operate in the TV broadcast bands while assuring that no harmful interference is caused to

the incumbent operation: digital TV and analog TV broadcasting, and low power licensed devices such as wireless microphones.

The standard was expected to be finalized in Q1 2010, but was finally published in July 2011.

IEEE P802.22.1 is a related standard being developed to enhance harmful interference protection for low power licensed devices

operating in TV Broadcast Bands. IEEE P802.22.2 is a recommended practice for the installation and deployment of IEEE 802.22

Systems. IEEE 802.22 WG is a working group of IEEE 802 LAN/MAN standards committee which was chartered to write the

802.22 standard. The two 802.22 task groups (TG1 and TG2) are writing 802.22.1 and 802.22.2 respectively.

802.24 (Vertical Applications TAG) Acts as a liaison and point of contact with industry organizations, other SDOs, government agencies, IEEE societies, etc., for

questions regarding the use of 802 standards in those vertical applications. Develops white papers, presentations and other

documents that do not require a PAR that describe the application of 802 standards to those vertical applications. Acts as a resource

for understanding 802 standards for regulatory agencies and for certification efforts by industry bodies, which require more than

one IEEE 802 WG's input. Release date- November 2012
