Wi-Fi 6E释放了Wi-Fi 6的潜力, 然而, it’s key to understand if now is the right time for your organisation.

在我之前的博客中, 聚焦于“Wi-Fi (R)演进”, I talked about the state of Wi-Fi technology and the importance of Wi-Fi 6 and 6E.

As the latest standard, Wi-Fi 6E promises unparallel performance and capacity levels. 然而, the question is: should customers move straight to Wi-Fi 6E and adopt it now for their new deployments?

Following are a few things to consider as you think about when is the right time to make the move.

考虑因素1:启用Wi-Fi 6E的国家

随着连接需求的稳步增长, many countries are making portions of the 6 GHz band available for Wi-Fi. 然而, some countries and regions are more restrictive than others, and organisations need to be aware of the status of the regulations in their region before starting a Wi-Fi 6E project.

•包括美国在内的国家.S., Canada and Brazil have already opened the entire spectrum for Wi-Fi 6E

•在欧盟和美国.K., only 500 MHz are available for Wi-Fi, while the other half of the spectrum is reserved for 5G

•其他国家, 比如阿根廷, Mexico and New Zealand are still considering their options, while many others haven’t yet made an announcement regarding Wi-Fi 6E adoption

The push towards this new technology is only growing and it is anticipated that as Wi-Fi 6E continues to evolve, 更多的国家迟早会采用它.

我的建议是:查看 最新的列表 of countries enabling Wi-Fi 6E, 由Wi-Fi联盟®发布.

考虑因素2:经过认证的Wi-Fi 6E设备

Only Wi-Fi 6E certified products will be able to use the 6 GHz band. 因此, organisations wanting to deploy a Wi-Fi 6E solution will need to consider the availability of certified access points and client devices to support their use cases.

Wi-Fi 6 technology is being adopted at an unparalleled rate, 在短短三年内达到50%的市场渗透率. The Wi-Fi Alliance forecasts that more than two billion Wi-Fi 6 and 6E devices will be shipped in 2022. 然而, only 15% of these will be Wi-Fi 6E capable devices.

T在这里 is a list of Wi-Fi 6E certified products already available in the market, including access points and other equipment from network vendors, 以及消费设备, 比如智能手机, 平板电脑, 笔记本电脑和智能电视等家庭娱乐设备. While the list is still limited, it is expected to continue to grow rapidly.

我的建议是:查看 Wi-Fi 6E认证产品 由Wi-Fi联盟®发布.

考虑因素3:户外覆盖

在很多市场, the 6 GHz band is already used by incumbent licensed services such as public safety, 细胞回程, 微波的链接, 卫星服务和电视广播服务. Many of these services are mission-critical which means Wi-Fi 6E interference must be strictly avoided.

这就引出了我们的第三个考虑，户外覆盖. Wi-Fi 6E distinguishes two types of devices with the objective of avoiding interference with the incumbent services:

1. Low power devices designed with limited transmission power. 这些包括:

• Low Power 室内 (LPI) access points, for indoor usage only. These devices cover typical indoor Wi-Fi installations, either enterprise-grade or residential.

•极低功耗(VLP)设备, 哪些是便携式的，用于个人可穿戴设备, 室内或室外. 这是一种新的个人设备, 可以在任何地方使用, 即使在车辆中, 比如虚拟现实眼镜, 可以通过Wi-Fi连接智能手机吗, 传输比蓝牙®更大的数据量.

2. Standard power access points are intended for outdoor deployments w在这里 more transmission power is needed to support greater distances. To ensure that the 6 GHz incumbents do not experience harmful interference from these Wi-Fi systems, Wi-Fi联盟与美国联邦通信委员会合作, has designed the Automated Frequency Coordination system (AFC), which manages spectrum usage requests in outdoor environments.

高通已经 最近宣布 他们的AFC解决方案在6 GHz频段增强Wi-Fi性能. In other countries, systems and specifications are in various phases of development. In general, Wi-Fi 6E for outdoor environments is not yet mature.

My recommendation: Plan outdoor environments with Wi-Fi 6 until the specifications for Wi-Fi 6E outdoor are ready.

展望未来

而Wi-Fi 6E正在加速发展, Wi-Fi 6 will still be the predominant technology for at least the next two years.
