The IEEE 802 LAN/MAN Standards Committee develops local area network (LAN) standards and metropolitan area network (MAN) standards.The most widely used standards are for the Ethernet family, Token Ring (TR), wireless LAN (WLAN), bridging and virtual bridged LANs. An individual Working Group (WG) provides the focus for each area. See also bridge, Ethernet, IEEE, LAN, MAN, standard, Token Ring, and WLAN.
The IEEE Working Group that concerns itself with standards and recommendations in the areas of architecture and internetworking of local area networks (LANs) and metropolitan area networks (MANs), security, network management, and protocol issues above the Data Link Layer. See also Data Link Layer, IEEE, LAN, and MAN.
The family of IEEE standards describing the over-the-air interfaces for a number of wireless local area networks (WLANs).Variously referred to in the vernacular as Wi-Fi (Wireless Fidelity) and Wireless Ethernet (the Ethernet CSMA/CA protocol is used in 802.11), 802.11 standards include infrared (IR) and radio frequency (RF) solutions, although there currently appear to be no practical applications for IR.The RF standards fall into the 2.4 GHz and 5 GHz ISM bands and offer theoretical bandwidth up to 54 Mbps. The original 802.11 standard (1997) operated in the 2.4 GHz band and supported theoretical data rates up to 2 Mbps. This early standard included a great number of options, which made interoperability of products difficult, or at least uncertain. As a result, 802.11 never gained any real traction in the market. Soon afterward, however, much improved extensions to 802.11 were finalized, and WLANs quickly gained in popularity. Current extensions include 802.11a, 802.11b, and 802.11g. Still under development is 802.11n. See also 802.11a, 802.11b, 802.11g, 802.11n, CSMA/CA, Ethernet, IEEE, ISM, RF, Wi-Fi, Wi-Fi5, and WLAN.
The IEEE standards for 100+ Mbps LANs using demand priority access. The focus was on 100VG-AnyLAN, a standard that is considered obsolete.
The IEEE standards initiative for Broadband Cable Access Method and Physical Layer Specification in Local and Metropolitan Networks.The standard was withdrawn.
The IEEE medium access control (MAC) and Physical Layer (PHY) specifications for wireless personal area networks (WPANs). Bluetooth is formalized in 802.15.1 (2002). 802.15.4 is the specification for a low-data-rate WPAN comprising devices of very low complexity transmitting at very low power levels and very long battery life. ZigBee is based on 802.15.4. See also Bluetooth, MAC, PAN, and ZigBee.
The IEEE specification entitled Air Interface for Fixed Broadband Wireless Access (BWA) Systems.The 802.16 Working Group was formed to develop a set of specifications to standardize Local Multipoint Distribution Service (LMDS) and Multichannel Multipoint Distribution Services (MMDS), once promising BWA technologies that proved too costly and unreliable.The 802.16 specifications evolved over a number of years, as follows.
The IEEE Working Group on Resilient Packet Ring (RPR) Access Method and Physical Layer Specifications. RPR standards address the resilient and efficient transfer of data packets over fiber optic local, metropolitan and wide area networks (LANs, MANs, and WANs) at rates scalable to many Gbps. See also RPR.
The IEEE Working Group that develops standards for Logical Link Control (LLC), which corresponds to the upper sublayer of the Data Link Layer in the OSI Reference Model. The LLC sublayer is concerned with issues of multiplexing, flow control, and detection and retransmission of dropped frames. See also Data Link Layer, flow control, IEEE, LLC, multiplexer, and OSI Reference Model.
The IEEE Working Group on Wireless Regional Area Networks (WRANs). 802.22 is an initiative directed toward the development of a cognitive radio air interface for use by license-exempt radios on a non-interfering basis in spectrum currently allocated to television broadcast service. See also cognitive radio, IEEE, and spectrum.
The IEEE standard that defines the carrier sense multiple access (CSMA) method of medium access control (MAC), and Physical Layer specifications.Although the term is commonly used interchangeably with Ethernet, 802.3 actually is a variation on the original Ethernet standard. (Note: Project 802 took its name from the fact that it was established in the year 1980, and the month 2, i.e., February.) See also, CSMA, Ethernet, IEEE, LAN, MAC, and standard.
The IEEE standard for Token Bus, a local area network (LAN) token passing protocol based on a physical bus topology. Token Bus is considered an orphaned standard, as the 802.4 committee disbanded in 2004 due to lack of interest. See also bus, Ethernet, IEEE, LAN, and token passing.

The IEEE standard for metropolitan area network (MAN) access method and Physical Layer specifications. Distributed Queue Dual Bus (DQDB) is defined here. Switched Multimegabit Data Service (SMDS) was derived from 802.6. This standard has been withdrawn. See also IEEE, DQDB, MAN, Physical Layer, and SMDS.
The IEEE Broadband Technical Advisory Group, chartered to develop standards for definition of a broadband cable plant design and establish guidelines for LAN construction within a physical facility such as a building.This standard has been withdrawn.
The IEEE Fiber Optic Technical Advisory Group, established to assess impact of fiber optics and to recommend standards.
The IEEE Integrated Services LAN (ISLAN) design for the integration of voice and data networks, both within the LAN domain and interfacing to publicly and privately administered networks running protocols such as FDDI and ISDN. The 802.9 Working Group developed the Isochronous Ethernet (IsoEthernet or IsoEnet) standard, which has been withdrawn.
