Wi-Fi 7: Wi-Fi’s Plaid Mode
With the 802.11be standard (a.k.a Wi-Fi 7), Wi-Fi has gone to plaid! As hinted at by its name, the IEEE 802.11be EHT “Extremely High Throughput” standard is primarily aiming to provide super-fast data rates for the next generation Wi-Fi 7 devices. The IEEE’s Project Authorization Request(1) (PAR) document sets the impressive goal of supporting a maximum throughput…

Wi-Fi 7: Wi-Fi 的 极速（Plaid） 模式
凭借802.11be标准 （亦称 Wi-Fi 7）, Wi-Fi 进入极速(Plaid)模式！ 顾名思义，IEEE 802.11be“极高吞吐量”(EHT) 标准的主要目标是让下一代 Wi-Fi 7 设备实现超快的数据速率。IEEE 的项目授权请求 [1](PAR) 文件设定了令人印象深刻的目标，计划支持至少 30 Gbps 的最大吞吐量，同时改善最坏情况下的延迟和抖动。这些性能目标旨在满足高分辨率视频、工业自动化、沉浸式体验和游戏等下一代应用的需求。为推动这一 WLAN 演进（革新）并解决未来的创新用例需求，802.11be 标准将采用经过关键升级并搭载全新功能（例如信道宽度加倍、调制阶数提升）的物理层 (PHY)。 在本博客中，我们将探讨推动下一代 Wi-Fi 发展的主要应用及其性能要求，以及满足 802.11be 标准设定的目标性能所需的关键 PHY 更改。 更高的速度需求从何而来? 有人可能会问， Wi-Fi 6 和 Wi-Fi 6E 高性能接入点和客户端设备不是才刚刚推出，为什么还要追求更高的性能？虽然现有标准已具备很高的性能，但可以预见的是，到 Wi-Fi 7 成熟时，扩展现实 (XR) 领域的新兴应用将会对吞吐量有更高的需求。增强现实、混合现实和虚拟现实的用例均可纳入 XR 范畴，其应用范围涵盖游戏、工业、医疗保健和企业建设等多种领域。对于这些新应用来说，需要高吞吐量的内容呈现，才能确保出色的用户体验并提高采用率。但更重要的是延迟、抖动和可靠性等关键性能指标，这些是提升真实感和交互性、保证最佳用户体验的关键所在。 高分辨率视频是沉浸式用户体验不可或缺的一环。如今的 4K 视频（4096 x 2160 像素）需要 20 到 40 Mbps 的吞吐量，而…
