Wireless networking standard in development / From Wikipedia, the free encyclopedia
Dear Wikiwand AI, let's keep it short by simply answering these key questions:
Can you list the top facts and stats about Wi-Fi 7?
Summarize this article for a 10 year old
IEEE 802.11be, dubbed Extremely High Throughput (EHT), is the latest of the IEEE 802.11 standard,[8][9] which is designated Wi-Fi 7.[10][11][12] It has built upon 802.11ax, focusing on WLAN indoor and outdoor operation with stationary and pedestrian speeds in the 2.4, 5, and 6 GHz frequency bands.[13]
Generation | IEEE standard |
Adopted | Maximum link rate (Mbit/s) |
Radio frequency (GHz) |
---|---|---|---|---|
Wi-Fi 8 | 802.11bn | 2028 | 100,000[1] | 2.4, 5, 6, 7, 42.5, 71[2] |
Wi-Fi 7 | 802.11be | 2024 | 1376–46,120 | 2.4, 5, 6[3] |
Wi-Fi 6E | 802.11ax | 2020 | 574–9608[4] | 6[lower-alpha 1] |
Wi-Fi 6 | 2019 | 2.4, 5 | ||
Wi-Fi 5 | 802.11ac | 2014 | 433–6933 | 5[lower-alpha 2] |
Wi-Fi 4 | 802.11n | 2008 | 72–600 | 2.4, 5 |
(Wi-Fi 3)* | 802.11g | 2003 | 6–54 | 2.4 |
(Wi-Fi 2)* | 802.11a | 1999 | 5 | |
(Wi-Fi 1)* | 802.11b | 1999 | 1–11 | 2.4 |
(Wi-Fi 0)* | 802.11 | 1997 | 1–2 | 2.4 |
*Wi‑Fi 0, 1, 2, and 3 are named by retroactive inference. They do not exist in the official nomenclature.[5][6][7] |
Throughput is believed to reach a theoretical maximum of 46 Gbit/s, although actual results are much lower.[14]
Development of the 802.11be amendment is ongoing, with an initial draft in March 2021, and a final version expected by the end of 2024.[11][15][16] Despite this, numerous products were announced in 2022 based on draft standards, with retail availability in early 2023. On 8 January 2024, the Wi-Fi Alliance introduced its "Wi-Fi Certified 7" program to certify Wi-Fi 7 devices. While final ratification is not expected until the end of 2024, the technical requirements are essentially complete.[14]
The global Wi-Fi 7 market was estimated at US$1 billion in 2023, and is projected to reach US$24.2 billion by 2030.[17]
