scholar jstor march 2026 learn how and when to remove this message ieee 802 11bn dubbed ultra high reliability uhr is an upcoming ieee 802 11 wireless networking standard 1 2 it is also designated wi fi 8 by the wi fi alliance as its designation suggests 802 11bn aims to improve the reliability of wireless communications rather than primarily increasing data rates 1 3 the standard is projected to be finalized in may 2028 4 wi fi and ieee 802 11 generations v t e genera tion 5 6 ieee standard adopt ed link rate mbit s frequency ghz 2 4 5 6 802 11 1997 1 2 802 11b 1999 1 11 802 11a 6 54 802 11g

11bn ultra high reliability study group was established in 2021 to address the need for more reliable wireless communications in increasingly dense and interference prone environments unlike previous wi fi generations that focused primarily on increasing peak data rates wi fi 8 represents a shift toward improving effective throughput and reducing latency in real world conditions 8 7 the development recognizes that while theoretical peak throughput of modern wi fi often exceeds application requirements users frequently experience intermittent connectivity issues due to environmental factors interference and protocol overhead in dense deployment scenarios 9 technical specifications edit 802 11bn maintains the same frequency bands as wi fi 7 2 4 ghz 5 ghz and 6 ghz the maximum channel bandwidth remains at 320 mhz and it continues to support 4096 qam modulation and up to 8 spatial streams the theoretical maximum data rate is expected to remain at approximately 23 gbps the same as wi fi 7 10 wi fi 8 requirements edit the 802 11bn standard wi fi 8 defines ultra high reliability capability for both isolated basic service sets bsss and overlapping bsss specifically compared to wi fi 7 wi fi 8 targets to increase throughput by 25 at a given signal to interference and noise ratio compared to wi fi 7 reduce latency by 25 for the 95th percentile of the latency distribution decrease mac protocol data unit mpdu loss by 25 especially for transitions between bsss 11 1 additionally the 802 11bn standard aims to enhance power save for access points including mobile ones and improve peer to peer operation 1 key features edit multi ap coordination edit wi fi 8 introduces enhanced coordination between multiple access points i e bsss many multi ap schemes have been discussed during the development of 802 11be but were postponed due to specification complexity so 802 11bn continues this direction in short multi ap leverages the classical wi fi mechanisms e g restricted target wake time spatial reuse beamforming and others by strengthening them thanks to enabling their cooperative work across multiple bsss correspondingly 802 11bn introduces multiple schemes each varying with targets efficiency complexity and overhead coordinated r twt co rtwt coordinated spatial reuse co sr coordinated beamforming co bf coordinated time division multiple access co tdma coordinated channel recommendation co cr 1 these multi ap schemes allow access points to manage interference more effectively while sharing spectrum resources enabling simultaneous transmissions that would otherwise conflict 12 seamless roaming edit wi fi 8 offers seamless roaming domain smd to address high latency and low reliability cases that are often experienced when devices move between wi fi networks smd defines a single entity covering multiple ap mlds which may not be colocated within a physical device within an smd the context i e the states of handshakes sequence numbers security keys and capabilities can be transferred between multiple ap mlds i e among wi fi networks such coordination reduces the unavailability time and decreases the loss ratio when a client mld device roams from one wi fi network to another an smd also enables a step by step per link transition of the client mld between ap mlds which promises to enable seamless connectivity 1 enhanced spectrum utilization edit dynamic sub channel operation dso and non primary channel access npca optimize spectrum allocation to improve performance when devices have disparate channel bandwidth capabilities these features address scenarios where high bandwidth access points must reduce their transmission capability to accommodate lower bandwidth clients 13 14 extended range capabilities edit the enhanced long range elr protocol data unit format is designed to overcome link budget imbalances between uplink and downlink transmissions improving spectrum efficiency for stations operating at greater distances from access points elr operates at 20 mhz bandwidth with support for bpsk and qpsk modulation 11 distributed tone resource units edit distributed tone resource units drus use a separate ofdm tone plan with distributed ofdm subcarriers specifically while a regular resource unit spans a continuous subset of subcarriers each dru spreads its tones across the entire available distribution bandwidth 1 this feature helps to overcome regulatory power spectral density limitations which are defined in terms of narrow bandwidth pieces thus achieving higher transmission power across a wider bandwidth for multiple stations in uplink transmissions this feature supports distribution bandwidths of 20 mhz 40 mhz and 80 mhz additional mcs values edit wi fi 8 introduces four new modulation and coding scheme values to provide finer granulation between existing mcs levels improving link adaptation accuracy and transmission rates by 5 30 depending on channel conditions 15 16 quality of service enhancements edit high priority enhanced distributed channel access hip edca and txop preemption mechanisms are designed to reduce long tail latency for time sensitive applications such as gaming video conferencing and real time communications 17 18 in device coexistence edit in device coexistence idc mechanisms improve coordination between wi fi and other wireless technologies such as bluetooth zigbee and ultra wideband within the same device reducing interference and improving overall performance ai offload edit in march 2026 ieee 802 11 approved the formation of an ai offload study group tasked with developing a project authorization request for a future amendment that would allow wi fi access points and other wi fi enabled edge devices to accept and execute compute intensive ai inference workloads on behalf of nearby devices such as ai enabled smart glasses and robotic systems requiring low latency access to compute resources 19 this work is separate from but running in parallel to the 802 11bn amendment itself and reflects early discussions toward a subsequent generation sometimes referred to as wi fi 9 19 development timeline edit the 802 11bn task group was formed in may 2021 development milestones include november 2023 task group work formally begins july 2025 draft 1 0 completed defining the technical scope letter ballot 291 on draft 1 0 generated more than 8 000 comments 20 january 2026 draft 1 3 approved after resolving approximately 740 comments at the victoria interim session 20 march 2026 draft 1 4 authorized with roughly 60 of comments resolved 19 may 2026 approximately 75 of comments resolved at the antwerp interim session draft 2 0 originally targeted for may 2026 slipped to a planned ballot in july 2026 20 19 target ratification may 2028 though the task group s own reporting has also cited a target as late as september 2028 21 wi fi 8 certification by the wi fi alliance is expected to begin around mid 2027 with commercial chipsets and pre standard products becoming available before final ratification following the pattern established by previous wi fi generations 20 applications edit wi fi 8 s reliability improvements are particularly targeted at applications requiring consistent low latency connectivity extended reality xr applications including vr and ar industrial automation and iot deployments high density public venues and enterprise networks real time gaming and interactive media telemedicine and remote healthcare applications 22 industry adoption edit major networking equipment manufacturers and chipset vendors are actively participating in the 802 11bn development process companies including mediatek qualcomm intel and broadcom are contributing to the specification and developing early implementations 8 the wireless industry anticipates wi fi 8 will be particularly valuable in environments where reliability is more critical than peak performance
