Wi-Fi 6 E解释了

Wi-Fi 6E在现有的Wi-Fi 6（802.11ax）标准上扩展，并允许访问新的6 GHz频段。Wi-Fi 6e采用了Wi-Fi 6的效率功能，例如OFDMA，WPA3和目标唤醒时间，并将其扩展到6 GHz频段，以提供更连续的频谱和更少的干扰。借助Wi-Fi 6E，企业可以支持新的用例，这些案例需要高清视频等多gabit速度。

How does Wi-Fi 6E work?

Wi-Fi today uses two bands: 2.4GHz and 5GHz. Wi-Fi 6E utilizes a third band: 6GHz. Wi-Fi 6E extends the same Wi-Fi 6 capabilities into the 6 GHz to allow greater efficiency, higher throughput, and increased security.

Why Wi-Fi 6E?

6 GHz频段的能力更大，该乐队解决了连接和拥堵问题。
较宽的频道，最多160 MHz，是高清视频和虚拟现实的理想选择。
No interference from microwaves, etc. because only 6E-capable devices can use the band.

哪些设备类型支持Wi-Fi 6e？

下图显示了所有Wi-Fi 6E设备类别，尽管并非所有设备类都在所有地理位置都支持。

What device classes support Wi-Fi 6E?

Standard Power (SP) AP: Supports outdoor and indoor operations, where the Standard Power APs are coordinated through an Automated Frequency Coordination Service (AFC) to mitigate 6Ghz Wi-Fi from interfering with incumbent services such as public safety and cellular backhaul, microwave links, satellite services, and TV broadcast services.
低功率室内(LPI)美联社:这个固定的我ndoor only class uses lower power levels and does not require an AFC. LPI APs for use in indoor enterprise deployment provide the same coverage as today’s Wi-Fi 6 APs and will provide similar 6Ghz coverage as today’s 5Ghz radios.
非常低的功率（VLP）AP：VLP从移动客户端提供移动室内或室外使用情况，用于用例，例如小单元覆盖，热点等。

这三个设备类的使用因地理和监管许可而异。

6个启用GHz的客户端设备（Wi-Fi 6E设备）的状态是什么？

在设备可以利用6 GHz频谱之前，必须提供支撑该带的芯片组。可用的芯片组来自几家不同的公司。此外，一些高端游戏手机正在通过Wi-Fi 6e支持进入市场。Wi-Fi Alliance启动了他们的Wi-Fi 6e认证计划，并保持了启用6e产品列表. This means that Wi-Fi 6E is now ready for mass market adoption.

How do I choose a Wi-Fi 6E vendor?

Choose a vendor that demonstrates

A track record of proven innovation
Commitment to certification by industry standards (Wi-Fi Alliance)
全面支持室内，室外，危险位置（Hazloc）和远程工人的投资组合

Wi-Fi 6e监管状况是什么？

在全球，美国，韩国，沙特阿拉伯，巴西，智利和危地马拉各自打开了1200 MHz。2020年11月，欧洲邮政和电信管理局会议（CEPT）发布了其决定开放最初的480 MHz频谱，用于低功率室内（LPI）设备以及非常低的功率（VLP）设备，该设备可能会运行室内和室内和室外。

What are the differences in Wi-Fi 6E in the US and EMEA?

欧洲达成了一项协议，可以为Wi-Fi分配5945 - 6425 MHz。即使这不是完整的6 GHz频段，它仍然提供许多额外的使用范围。但是，为了在全球范围内协调法规并从规模经济中受益并满足未来的产能需求，Wi-Fi行业正在与欧洲的监管机构合作开放6425 - 7125 MHz乐队。

Within Europe, the UK and Denmark deviate slightly from the European agreement. The UK will allow slightly higher transmit power and have a little more spectrum to use (5925 – 6425 MHz).

Wi-Fi 6 versus Wi-Fi 6E

	Wi-Fi 6	Wi-Fi 6E (6 GHz)
Band	2.4 and 5.0 GHz spectrum	2.4, 5 and now 6 GHz spectrum (Devices must be 6 GHz enabled.)
Features	Multi User efficiencies, multi-user input/output (MU-MIMO) to remove bottlenecks OFDMA to create carpool lanes to piggyback smaller packets like voice data Target Wake Time (TWT) to allow APs to ping IoT devices at longer intervals & reduce traffic/extend battery life WPA3并增强开放，以增强客人访问安全性	Includes all features in Wi-Fi 6 plus More capacity in the 6 GHz band Wider channels, up to 160 MHz, which are ideal for high-def video and virtual reality No interference from microwaves, etc. because only 6E-capable devices can use the band
Benefits	Increased efficiencies to provide greater throughput with the same number of APs, ideal for dense environments and large numbers of IoT devices	支持更大的容量和更广泛的渠道，以支持多目标流量，非常适合高清视频和AR/VR（增强现实/虚拟现实）
