To achieve these objectives, the IEEE 802 standards cover a broad spectrum of network technologies, such as Ethernet (802.3), Wi-Fi (802.11), and various other Wireless Personal Area Network (WPAN) technologies like Bluetooth (802.15.1) and Zigbee (802.15.4). Each of these separate standards has specific applications and areas of focus, ranging from smart homes and offices to corporate networks and large-scale infrastructure projects.

By defining a common ground for networking devices, IEEE 802 standards contribute to a more connected world and drive innovation, enabling the growth and expansion of modern communication systems and networks that are essential for our daily lives.

Examples of IEEE 802

IEEE 802 is a family of IEEE standards dealing with local area networks and metropolitan area networks. Here are three real-world examples of these technologies:IEEE3 – Ethernet: Ethernet is a widely used technology for wired local area networks (LANs) across homes, offices, and large commercial buildings. This technology allows devices such as computers, printers, and switches to connect to one another in a network, enabling data transfer for communication and collaboration. It operates at various speeds such as 10 Mbps, 100 Mbps, 1 Gbps, and 10 Gbps. Ethernet has become the defacto standard for wired connectivity.

IEEE11 – Wi-Fi: Wi-Fi is one of the most popular wireless LAN technologies in use today, providing internet access to billions of devices worldwide. Wi-Fi technology allows computers, smartphones, tablets, smart TVs, and other IoT devices to connect to a network and the internet through a wireless access point. It operates on4 GHz and 5 GHz frequency bands, and Wi-Fi technology has seen numerous improvements with advancements such as

11a/b/g/n/ac/ax. Areas with widespread Wi-Fi access, such as coffee shops, hotels, airports, and many public spaces, have become commonplace.IEEE4 – Zigbee: Zigbee is a low-power wireless communication technology widely used for home automation, industrial control, and smart energy applications. Zigbee devices such as smart switches, sensors, and light bulbs connect to a Zigbee-enabled hub or gateway, enabling remote control and monitoring from smartphones, tablets, or computers. This technology operates on the

4 GHz frequency band and is known for its low energy consumption and mesh networking capabilities, where devices can relay signals and function as a self-healing network.

IEEE 802 FAQ

What is IEEE 802?

IEEE 802 is a family of IEEE (Institute of Electrical and Electronics Engineers) standards for local area networks (LAN) and metropolitan area networks (MAN).
