Many of the widely used LAN protocols have been developed in North America through the offices of the Institute of Electrical and Electronic Engineers (IEEE). The American National Standards Institute (ANSI) has subsequently accepted and incorporated these standards, and they now bear the ANSI imprimatur.

The IEEE develops LAN standards in the IEEE 802 family of committees. Of interest in this chapter are the following IEEE committees, each with published standards, which continue to evolve:

802.1 High-Level LAN Interface

802.2 Logical Link Control (LCC)

802.3 CSMA/CD Networks Ethernet working group

802.4 Token Bus Networks (inactive)

802.5 Token Ring Networks (inactive)

802.11 Wireless LAN (many subset such as 802.11b, 802.11d, others)

802.15 Wireless Personal Area Network

802.16 Broadband Wireless Access

802.17 Resilient Packet Ring

802.18 Radio Regulatory

802.19 Coexistence

802.20 Mobile Broadband Wireless Access (MBWA)

802.21 Media Independent Handoff list as of 3/22/04
