IEEE 802.11be, dubbed Extremely High Throughput (EHT), is the latest of the IEEE 802.11 standard,[9][10] which is designated Wi-Fi 7.[11][12][13] 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.[14]

Throughput is believed to reach a theoretical maximum of 46 Gbit/s, although actual results are much lower.[15]

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.[12][16][17] 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,[15] and there are already products labeling themselves as "Wi-Fi 7" as of February 2024.[18][19][20]

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.[21]
