Setting New Performance Standards with IEEE 802.11bn: An In-Depth Overview of Wi-Fi 8

More information

IEEE 802.11bn introduces the ultra-high reliability amendment that will serve as the basis for Wi-Fi 8. Unlike previous Wi-Fi generations that focused primarily on increasing peak throughput, IEEE 802.11bn targets measurable improvements in real-world performance: a 25% increase in throughput under throughput-over-range conditions, a 25% reduction in 95th percentile latency, and a 25% decrease in throughput under range conditions. of the probability of packet loss during basic connections. service set transitions. The amendment retains the basic physical layer parameters of Wi-Fi 7 – up to 320 MHz of channel bandwidth, 4096-level quadrature amplitude modulation, and eight spatial streams – while adding new physical layer capabilities such as distributed resource units and enhanced long-range protocol data units, as well as advanced media access control features, including coordination of multiple access points and seamless roaming within of a mobility domain.
