802Familie

802Familie is the German-language designation for the IEEE 802 family of networking standards, a core set of specifications for local and metropolitan area networks. Maintained by the IEEE 802 LAN/MAN Standards Committee, the 802 family covers both wired and wireless technologies that enable data communication within networks. The most widely used 802 standards are 802.3 for Ethernet and 802.11 for wireless LANs, with additional parts addressing short-range, broadband, and bridging functions.

The standards in the 802 family define the physical layer and data-link layer requirements for network devices. They are developed through working groups, with amendments and revisions that are ratified after review. Individual standards, such as 802.11 and 802.3, describe specific technologies, while others provide shared mechanisms like MAC bridging and quality of service features via 802.1.

In common usage, 802Familie serves as shorthand for the entire IEEE 802 suite rather than a single protocol. In English-language references the term IEEE 802 family is used. The terminology highlights the interconnected nature of the standards and their role in ensuring interoperability.

Impact and significance: The 802 standards underpin most modern local area networks and influence device certification and interoperability. Manufacturers reference the appropriate substandard numbers, for example 802.11ac or 802.3. The committee continues to develop new work as networking needs evolve.
