Wi-Fi 8即将到来

Core Viewpoint - Qualcomm's vision for Wi-Fi 8 focuses on reliability and aims to address issues such as packet loss and connection delays, with a projected launch in 2028 [2][9]. Group 1: Design Philosophy - Qualcomm engineers propose a structural shift in designing standards around degraded conditions rather than optimal ones, targeting a 25% improvement in actual throughput under poor signal quality, interference, or at the network edge [3]. - The approach emphasizes coordination among access points rather than treating them as isolated entities, allowing for shared scheduling of transmissions and improved coverage management [3]. Group 2: Technical Enhancements - New features include Coordinated Space Reuse (Co-SR) and Coordinated Beamforming (Co-BF), which enhance signal quality and coverage while reducing interference, potentially increasing throughput by 15% to 59% depending on deployment density [4]. - Wi-Fi 8 introduces a more refined Modulation and Coding Scheme (MCS) that smooths performance transitions, improving spectrum efficiency during coverage degradation or roaming [6]. - Non-Primary Channel Access (NPCA) allows devices to utilize secondary channels when primary channels are congested, enhancing spectrum efficiency in dense environments [7]. Group 3: Standardization Progress - The draft for Wi-Fi 8 specification 1.0 is expected to be released in Q3 2025, with the Wi-Fi Alliance certification program aiming for January 2028 and final IEEE approval anticipated by mid-2028 [9]. - Unlike previous standards, Wi-Fi 8 is designed as a single-version specification, meaning all core functionalities will be released simultaneously, including mandatory features like coordinated frameworks and seamless roaming logic [11]. - The development process has received over 6,000 technical contributions, focusing on throughput, reliability, connectivity, and future modulation technologies [11].
