IEEE: who comes up with the Wi-Fi and Ethernet standards
The IEEE (Institute of Electrical and Electronics Engineers) is the world's largest professional organisation of electronics and electrical engineers. It develops technical standards, including Wi-Fi (IEEE 802.11) and Ethernet (IEEE 802.3).
In plain words
The IEEE is like the committee that writes the rules of football: the size of the ball and pitch, the number of players. Thanks to shared rules, one maker's balls fit another maker's goals. Wi-Fi works the same way: one brand's router works with another brand's laptop because everyone plays by the 802.11 rules.
How it works
- Engineers from different companies form working groups.
- The groups write the standard's technical specifications.
- The documents are discussed and approved by vote.
- Manufacturers build devices to the standard.
- The Wi-Fi Alliance assigns marketing names (Wi-Fi 6, Wi-Fi 7) and certifies compatibility.
Where you'll see it
You see IEEE standard numbers in specs: 802.11ac (Wi-Fi 5), 802.11ax (Wi-Fi 6), 802.11be (Wi-Fi 7), 802.3 (Ethernet), 802.15.4 (the basis of Zigbee and Thread).
Does it matter when buying
It helps to know that "802.11be" and "Wi-Fi 7" are the same thing. When buying, look at the friendly generation names; the standard numbers help you make sense of the technical specs.
Myths
- Myth: The IEEE is a government body. Reality: It is an independent professional organisation.
- Myth: Wi-Fi 7 was invented by one company. Reality: Engineers from many companies developed it within the IEEE.
