What Does Ultra High Reliability Mean from a Physical-Layer Perspective? (Download)
The release of Wi-Fi 8 (802.11bn) Draft 1.0 has provided significant clarity on the physical-layer features meant to achieve Ultra High Reliability (UHR). While some might have anticipated groundbreaking new modulations, wider channels beyond 320 MHz, or entirely new MIMO schemes, this initial draft reveals a more nuanced approach. Wi-Fi 8 introduces refined mechanisms to optimize and fine-tune existing features, enhancing their capabilities.
It's a reality that, even with Wi-Fi 7's extensive feature set — including UL-OFDMA, MLO, and 320-MHz channels — the widespread real-world deployment remains a challenge. Despite compelling marketing, practical network implementation, and making such advanced features consistently perform, these are complex tasks.
