Reference : IEEE 802 Standards
LMSC (the LAN-MAN Standards Committee) or IEEE Project 802
develops LAN and MAN standards for
the lowest two layers of the OSI Model. The release from LMSC says that 802 was
simply the next number in the sequence being issued by the IEEE for standard projects. But sometimes people relate the
naming to its historical first meeting which was held in February, 1980.
LMSC coordinates its work with standard bodies as well as industry alliances in developing global standards.
LMSC has been very productive and that is proven by many "802"
standards that are used widely. In the past, 802 was not a
consumer term but with the popularity of Wi-Fi or 802.11a/b/g,
the "802" has become a familiar term. The following shows
important 802 standards in category list:
IEEE 802: Overview & Architecture
IEEE 802.1: Bridging & Management
IEEE 802.2: Logical Link Control
IEEE 802.3 : CSMA/CD Access Method
IEEE 802.5 : Token Ring Access Method
IEEE 802.11: Wireless Local Area Networks
IEEE 802.12: Demand Priority Access Method
IEEE 802.15: Wireless Personal Area Networks
IEEE 802.16: Broadband Wireless Metropolitan Area Networks
The number that follows the 802 and the dot refers to the Working Group (WG) that
produces the standard. The unique letter designation that often follows next refers to
a Task Group (TG) within a Working Group
that works on a particular standard or modifications to preceding standards.
