As of 2009, it is only being licensed in the United States by the FCC. Increased power limits allow a range up to 5,000 m. ^ a b IEEE 802.11y-2008 extended operation of 802.11a to the licensed 3.7 GHz band.^ a b c d e f g This is obsolete, and support for this might be subject to removal in a future revision of the standard.Single carrier, low-power single carrier OFDM, single carrier, low-power single carrier Support of direct links, managed by an access point.More flexible preamble puncturing scheme,.Optimized channel sounding that requires less airtime,.Frame formats with improved forward-compatibility,.IEEE 802.11ax Scheduled Operation extensions for reduced jitter/latencyĪpart from the features mentioned in the PAR, there are newly introduced features:.Bounded latency: credit-based (IEEE 802.1Qav) and cyclic/time-aware traffic shaping (IEEE 802.1Qch/Qbv), asynchronous traffic scheduling (IEEE 802.1Qcr-2020).IEEE 802.11ak Enhancements for Transit Links Within Bridged Networks (802.11 links in 802.1Q networks).IEEE 802.11aa MAC Enhancements for Robust Audio Video Streaming ( Stream Reservation Protocol over IEEE 802.11).IEEE 802.1AS timing and synchronisation.Integrating Time-Sensitive Networking (TSN) IEEE 802.1Q extensions for low-latency real-time traffic:.If needed, adaptation to regulatory rules specific to 6 GHz spectrum,.Enhanced link adaptation and retransmission protocol (e.g.Multi-Access Point (AP) Coordination (e.g.The main candidate features mentioned in the 802.11be Project Authorization Request (PAR) are: With preamble puncturing, a portion of the channel that is impacted by interference can be blocked off while continuing to use the rest of the channel. Flexible Channel Utilization – Interference currently can negate an entire Wi-Fi channel.16 spatial streams and Multiple Input Multiple Output ( MIMO) protocol enhancements.Theoretically as little as 1% the latency of Wi‑Fi 6, through the use of MLO.Multi-Link Operation (MLO), a feature that increases capacity by simultaneously sending and receiving data across different frequency bands and channels.4096- QAM (4K-QAM) enables each symbol to carry 12 bits rather than 10 bits, resulting in 20% higher theoretical transmission rates than WiFi 6's 1024-QAM.The following are core features that have been approved as of Draft 3.0: The global Wi-Fi 7 market is estimated at 1 billion USD in 2023, and is projected to reach 24.2 billion USD by 2030. Despite this, numerous products were announced in 2022 based on draft standards, with retail availability in early 2023. ĭevelopment of the 802.11be amendment is ongoing, with an initial draft in March 2021, and a final version expected by early 2024. Throughput is expected to reach a theoretical maximum of 46 Gbit/s, although actual results will be much lower. It will build 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. IEEE 802.11be, dubbed Extremely High Throughput (EHT), is the next amendment of the IEEE 802.11 standard, which will be designated Wi-Fi 7. They do not exist in the official nomenclature. * Wi‑Fi 0, 1, 2, and 3 are named by retroactive inference.
