Introduction to Wi-Fi 8 (IEEE 802.11bn) Training by Tonex
Wi-Fi 8 (IEEE 802.11bn) represents a fundamental shift in wireless LAN design—from the historical pursuit of ever-higher peak throughput toward deterministic performance, ultra-high reliability, and predictable latency. Designed to support mission-critical, industrial, healthcare, defense, and XR applications, Wi-Fi 8 introduces architectural, MAC, and PHY innovations that enable carrier-grade robustness in unlicensed spectrum.
This intensive 2-day course provides a deep technical and systems-level understanding of Wi-Fi 8, covering reliability-driven design goals, coordinated multi-AP operation, latency guarantees, interference resilience, and coexistence with 5G/6G private networks. Participants will explore how Wi-Fi 8 enables deterministic wireless Ethernet-like behavior for Industry 4.0, robotics, medical devices, and real-time control systems.
