产品和性能信息
速度提高近 3 倍：802.11ax 2x2 160 MHz 可实现 2402 Mbps 的最大理论数据速率，比标准 802.11ac 2x2 80 MHz (867 Mbps) 快约 3 倍（2.8 倍），如 IEEE 802.11 无线标准规格所注明，并要求使用配置相似的 802.11ax 无线网络路由器。
4 倍容量/可扩展性：此声明基于对规模类似的 802.11ax 与 802.11ac 网络的总体网络容量比较。IEEE 802.11-14/0165r1 802.11ax 规格变更定义了对 IEEE 802.11 物理层 (PHY) 和 IEEE 802.11 媒体访问控制层 (MAC) 的标准化修改，支持至少一种操作模式能够在密集部署场景中实现每站点至少 4 倍的平均吞吐量提升（在 MAC 数据服务接入点测量），同时保持或提高每个站点的能效。如需更多详细信息，请访问：https://mentor.ieee.org/802.11/dcn/14/11-14-0165-01-0hew-802-11-hew-sg-proposed-par.docx。
延迟降低 75%：基于 802.11ax 的英特尔模拟数据（79%，使用 9 个客户端，含 OFDMA 和不含 OFDMA）。不含 OFDMA 的平均延迟为 36 毫秒，含 OFDMA 的平均延迟降低为 7.6 毫秒。延迟改进要求 802.11ax (Wi-Fi 6) 路由器和所有客户端支持 OFDMA。如欲了解更多信息，请访问 intel.cn/wifi6disclaimers。
WPA3 Wi-Fi 安全功能：Wi-Fi Alliance 行业联盟将认证 Wi-Fi 6 产品是否符合 IEEE 802.11ax 标准，并将 WPA3 安全认证作为先决条件，以确保采用最新的 Wi-Fi 安全功能。WPA3 简化密码：WPA3 使用 Simultaneous Authentication of Equals (SAE) 替换 WPA2 使用的预共享密钥 (PSK) 交换协议。SAE 更安全地处理初始密钥交换并使用正向保密，从而更能抵御脱机解密攻击，并提供更强的基于密码的身份验证。WPA3 增强保护：额外的网络保护来自于 802.11ax 网络中相当于 192 位的加密强度，优于 WPA2 中使用的 128 位 AES 加密。
最佳 Wi-Fi 6：英特尔® Wi-Fi 6 (Gig+) 产品支持可选的 160 MHz 通道，从而使典型的 2x2 802.11ax PC Wi-Fi 产品可达到最快的理论最大速度 (2402 Mbps)。与标准 2x2 (1201 Mbps) 或 1x1 (600 Mbps) 802.11ax PC Wi-Fi 产品（仅支持 80 MHz 通道的强制要求）相比，高级英特尔® Wi-Fi 6 (Gig+) 产品可使最大理论速度加快 2 - 4 倍。
802.11ac 2x2 160MHz 实现了 1733 Mbps 最大理论数据速率，是标准 802.11ac 2x2 80MHz (867Mbps) 速度的 2 倍，是基准 1x1 BGN (150Mbps) Wi-Fi（IEEE 802.11 无线标准规格记录）速度的近 12 倍，并且要求使用配置类似的 802.11ac 无线网络路由器或更高版本。要实现千兆无线速度，网络需要支持 160MHz 通道的无线路由器/接入点。
