Wi-Fi Optimized Connectivity

提升网络移动性

Wi-Fi CERTIFIED Optimized Connectivity™–是Wi-Fi CERTIFIED Vantage™的一个关键组成部分。它是一项Wi-Fi Alliance® 认证计划，通过减少传输时间开销以及对所选接入点进行更快的身份验证，来提升网络移动性，并在用户网络内或跨网络漫游时为其提供更稳定的网络连接。Wi-Fi Optimized Connectivity™使用户在整个漫游过程中体验高质量的网络连接，由于接入点和客户端设备可以实现信息交换，以下主要益处得以实现：

优化网络发现与选择：移动端和接入点采用改进的信道扫描技术，快速识别潜在的可供连接Wi-Fi® 网络。

链路质量评估：基于双向链路质量估计与网络拓扑信息，为客户端设备提供指标，协助其迅速做出决定，选择能够提供最佳连接的接入点。

快速身份验证：使用快速初始链接设置(FILS)身份验证，设备可以协同工作以减少传输时间开销，并对所选接入点或网络进行更快的身份验证。

高效传输：显著减少管理帧传输，使设备能够用更少的时间响应管理信息，用更多的时间传输用户数据。

运行中的Wi-Fi Optimized Connectivity

一项现场测试表明，使用Wi-Fi Optimized Connectivity关键组件的设备比那些未通过这些技术认证的设备性能更好。使用Wi-Fi Vantage™功能来增强网络发现和高级漫游，结果显示相较于未获得Wi-Fi 优势认证的Wi-Fi设备，这些设备的设置时间减少了76%，管理帧和信标拥堵平均减少了76%，性能显著提高。执行测试的服务提供商能够高效的管理网络资源，容纳更多的设备，提供更高的客户满意度。终端用户可以体验更快的连接，更加稳定的语音、视频通话。

Wi-Fi Optimized Connectivity和Wi-Fi 6E

Wi-Fi Optimized Connectivity功能也是6GHz频段高效的发现网络接入点的关键因素。同时运行2.4GHz频段或5GHz频段以及6GHz频段的Wi-Fi 6接入点——也被称为Wi-Fi 6E——在2.4 GHz和，或5 GHz频段传输一个减小邻居报告元素，来实现6GHz基本服务集合(BSSs)的频外探查。为了最大限度地提高频谱效率和利用率，同时在多个频段运行的接入点都默认将禁用6GHz频段的FILS发现帧和主动探测响应帧。仅在6GHz频段运行的接入点传输FILS发现帧或者主动响应探测帧，从而实现高效的频道扫描。对于那些运行于其他频段和信道的BSSs，尤其是那些对主动扫描有监管限制的动态频率选择信道，Wi-Fi Optimized Connectivity接入点可以使用相同的功能来实现高效探查。

Frequently Asked Questions

Which IEEE standards does Wi-Fi Optimized Connectivity leverage to manage spectrum and network resources?

Wi-Fi Optimized Connectivity leverages features from IEEE 802.11ai, IEEE 802.11k, and IEEE 802.11ax to better manage spectrum and network resources, increase mobility, and provide the best possible user experience.

  • Select features from IEEE 802.11ai-2016, known as Fast Initial Link Setup (FILS), together with enhancements introduced in IEEE 802.11ax, introduce mechanisms to aid efficient discovery of APs and fast authentication
  • New features first introduced in IEEE 802.11-2016 and IEEE 802.11ax provide for enhanced metrics for AP and network selection
  • Additional features from IEEE 802.11k focus on informing client devices of channels on which neighboring APs are operating to optimize scanning

Which Wi-Fi Alliance technologies does Wi-Fi Optimized Connectivity employ?

Wi-Fi Optimized connectivity relies on several Wi-Fi Alliance features and mechanisms to help optimize network capacity by controlling network access according to received signal strength indication (RSSI), and define a variety of signaling and rules to help ensure consistent, interoperable behavior of devices and APs. Wi-Fi CERTIFIED Agile Multiband™ is also a prerequisite for Wi-Fi Optimized Connectivity, ensuring efficient management of Wi-Fi network resources in changing network environments.
