Wi-Fi 8 focuses on reliability and effective throughput over raw speed increases

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.
