IEEE 802.11bn Defines Ultra-High Reliability for Wi-Fi 8
The standard prioritizes reliability over raw throughput. Physical layer features overcome uplink power limits with distributed resource units that spread tones across wider distribution bandwidths to boost per-tone transmit power, and enhanced long range protocol data units that use power-boosted preamble fields and frequency-domain duplication to extend uplink coverage (https://content.knowledgehub.wiley.com/setting-new-performance-standards-with-ieee-802-11bn-an-in-depth-overview-of-wi-fi-8/).
MAC coordination reduces interference and latency through multi-AP schemes including coordinated beamforming, spatial reuse, time division multiple access, and restricted target wake time, plus non-primary channel access and priority enhanced distributed channel access (https://content.knowledgehub.wiley.com/setting-new-performance-standards-with-ieee-802-11bn-an-in-depth-overview-of-wi-fi-8/).
Seamless mobility domains eliminate reassociation delays during AP transitions while dynamic power save and multi-link power management let devices trade capability for battery life without losing connectivity (https://content.knowledgehub.wiley.com/setting-new-performance-standards-with-ieee-802-11bn-an-in-depth-overview-of-wi-fi-8/).
