{{Short description|IEEE standards for local and metropolitan area networks}}

{{OSI model|expanded=data}}

'''IEEE 802''' is a family of [[Institute of Electrical and Electronics Engineers]] (IEEE) standards for [[local area network]]s (LANs), [[personal area network]]s (PANs), and [[metropolitan area network]]s (MANs). The IEEE 802 LAN/MAN Standards Committee (LMSC) maintains these standards. The IEEE 802 family of standards has had twenty-four members, numbered 802.1 through 802.24, with a [[working group]] of the LMSC devoted to each. However, not all of these working groups are currently active.

The IEEE 802 standards are restricted to [[computer network]]s carrying variable-size packets, unlike [[cell relay]] networks, for example, in which [[data]] is transmitted in short, uniformly sized units called cells. [[Isochronous signal]] networks, in which data is transmitted as a steady stream of [[octet (computing)|octet]]s, or groups of octets, at regular time intervals, are also outside the scope of the IEEE 802 standards.

The number 802 has no significance: it was simply the next number in the sequence that the IEEE used for standards projects.<ref>{{cite web |author=Institute of Electrical and Electronics Engineers |title=Overview and Guide to the IEEE 802 LMSC |date=September 2004 |url=https://grouper.ieee.org/groups/802/802%20overview.pdf |access-date=October 13, 2020 }}</ref>

The services and protocols specified in IEEE 802 map to the lower two layers (data link and physical) of the seven-layer [[OSI model|Open Systems Interconnection (OSI)]] networking reference model. IEEE 802 divides the OSI data link layer into two sub-layers: [[logical link control]] (LLC) and [[medium access control]] (MAC), as follows:  
*[[Data link layer]]
**[[Logical link control|LLC sublayer]]
**[[Medium access control|MAC sublayer]]
*[[Physical layer]]
Everything above LLC is explicitly out of scope for IEEE 802 (as "upper layer protocols", presumed to be parts of equally non-OSI [[Internet reference model]]).

The most widely used standards are for [[Ethernet]], Bridging and Virtual Bridged LANs, [[Wireless LAN]], [[Wireless PAN]], [[Wireless MAN]], [[Wireless Coexistence]], Media Independent Handover Services, and [[Wireless RAN]]. <ref>{{Cite web |title=IEEE802 |url=https://www.ieee802.org/ |access-date=2022-11-27 |website=www.ieee802.org}}</ref>
