About

The standards define the physical layer and data link layer specifications for the implementation of networking protocols. IEEE 802 has played a crucial role in the development and expansion of various Ethernet technologies and wireless communication standards. The IEEE 802 family includes several subgroups, each focusing on specific areas of network technology. These subgroups, numbered from 802. 1 to 802. 22, cover topics such as bridging and network management, security, local and metropolitan area networks, wireless communication, and vehicular technology. The standards within each subgroup are developed through a rigorous process of draft proposals, review, and consensus building among the participating members. The most well-known standard within IEEE 802 is the Ethernet standard, officially known as IEEE 802. 3. It defines the physical layer and media access control (MAC) sublayer of Ethernet networks. The standard has evolved over time to include faster data rates and newer technologies, such as gigabit Ethernet and 10 Gigabit Ethernet. Another important subgroup within the IEEE 802 family is IEEE 802. 11, which defines wireless LAN (Wi-Fi) protocols. This subgroup has been responsible for the development of popular wireless technologies such as Wi-Fi 4 (802. 11n), Wi-Fi 5 (802. 11ac), and Wi-Fi 6 (802. 11ax). These standards have revolutionized wireless networking by introducing faster data rates, improved range, and higher capacity. IEEE 802 standards are widely adopted and used in various industries and applications. They provide a common framework and interoperability for networking devices, enabling seamless communication between different manufacturers' products. This has facilitated the growth and connectivity of networks worldwide. Overall, IEEE 802 standards have been instrumental in shaping the evolution of networking technologies. They continue to play a vital role in ensuring compatibility and innovation in the field of LANs, MANs, and wireless communication.
