- Targets 25% reduction in 95th percentile latency and MPDU loss.
- Wi-Fi 7 launched in early 2024.
- Wi-Fi 7 offers theoretical speeds up to 46 Gbps.
- Wi-Fi 7 improves performance in congested environments.

- Wi-Fi 7 is backward compatible with older devices.
A New Direction for Wi-Fi Development
For the first time in several generations, the upcoming Wi-Fi 8 standard, designated "Ultra High Reliability" by the IEEE, is not primarily focused on increasing maximum theoretical data rates. While previous Wi-Fi versions consistently delivered significant speed bumps, Wi-Fi 8 shifts its emphasis to improving network reliability and effective throughput in real-world scenarios.
Maintaining Current Speed Capabilities
Wi-Fi 8 is expected to maintain similar maximum data rates, spatial stream support, 4096-QAM modulation, operating bands, and 320MHz channel bandwidth as Wi-Fi 7. This decision reflects the current adequacy of Wi-Fi 7's 23 Gbit per band theoretical throughput for most users' internet speeds, making further raw speed increases less critical at this stage.
Focus on Reliability and Efficiency
Instead of speed, the IEEE's development goals for Wi-Fi 8 include a 25% increase in throughput across different signal-to-interference-and-noise ratio (SINR) levels. It also aims to reduce latency by 25% for 95th percentile scenarios and decrease MAC protocol data unit (MPDU) loss by 25%. These improvements are designed to enhance performance by reducing interference and handling non-ideal network conditions more effectively.
Future Competition with Cellular Networks
Wi-Fi 8 is positioned to compete with future cellular technologies like 6G, which is expected to arrive in the early 2030s. Wi-Fi 8 is anticipated to be finalized in 2028, setting the stage for a period where both technologies will vie for connectivity dominance, particularly in areas where reliability and consistent performance are paramount.

Wi-Fi 7, launched in early 2024, provides theoretical speeds up to 46 Gbps and improved performance in congested environments compared to Wi-Fi 6E, primarily through features like Multi-Link Operation and wider 320 MHz channels. While offering significant upgrades, its real-world benefits depend on internet plans and device usage, and it maintains backward compatibility with older devices.
The IEEE is developing Wi-Fi 8, dubbed "Ultra High Reliability," which will prioritize network reliability and effective throughput rather than increasing maximum theoretical data rates. This marks a shift from previous Wi-Fi generations that primarily focused on speed enhancements, aiming to improve performance in non-ideal conditions and reduce latency.
