Wi-Fi 6 E解释说明

Wi-Fi 6e展开现有的Wi-Fi 6（802.11AX）标准，并允许访问新的6 GHz频段。Wi-Fi 6e采用Wi-Fi 6的效率特征，如OFDMA，WPA3和目标唤醒时间，并将它们扩展到6 GHz频带，以提供更连续的频谱和更少的干扰。通过Wi-Fi 6e，企业可以支持需求多千兆位速度等高清视频的新用例。

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频段的容量更多，解决了连接和拥塞问题。
更广泛的频道，高达160 MHz，这对于高缺陷视频和虚拟现实是理想的。
No interference from microwaves, etc. because only 6E-capable devices can use the band.

什么设备类型支持Wi-Fi 6e？

下图显示了所有Wi-Fi 6e设备类，虽然所有地理位置都不支持所有设备类。

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提供来自移动客户端的移动室内或室外用途，因为小型电池覆盖，热点等。

Use of these three device classes varies by geography and regulatory permissions.

启用6个GHz的客户端设备（Wi-Fi 6e设备）的状态是多少？

在设备可以利用6 GHz频谱之前，必须可用支持此频段的芯片组。可用的芯片组来自几家不同的公司。此外，一些高端的游戏手机正在使用Wi-Fi 6e的支持。Wi-Fi联盟推出了Wi-Fi 6e的认证计划，并保持了一个列出了6E个支持的产品. 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)
一个完整的投资组合，支持室内，户外，危险地点（Hazloc）和偏远工人

什么是Wi-Fi 6e监管状况？

在全球范围内，美国，韩国，沙特阿拉伯，巴西，智利和危地马拉每次开设1200 MHz。2010年11月，欧洲邮政和电信管理部门（Cept）发布了其决定，为低功率室内（LPI）器件和非常低的电源（VLP）设备开辟了初始480MHz的频谱，这些设备可以在室内和室外运行。

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

欧洲达成协议，为Wi-Fi分配5945 - 6425 MHz。即使这不是完整的6 GHz频段，它仍然提供了很多额外的使用频谱。然而，为了协调全球的法规并受益于规模经济并适应未来的能力需求，Wi-Fi Industry正在与欧洲的监管机构合作，开辟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，以增强访客访问安全性	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频道来支持多字交易，非常适合高清视频和AR / VR（增强现实/虚拟现实）
