WiFi 7 Explained — What Is It and When Is It Coming?

The constant evolution of WiFi standards is the reason why a new router can significantly improve your connection speeds, eliminate signal weak zones, and generally provide a much better user experience.

In 2022, the latest WiFi standard available is WiFi 6E, but its successor is already in the works, and it will be called — you’ve guessed it — WiFi 7 (Wi-Fi 7). In this article, we explain why the standard is worth looking forward to, especially if you’re craving better WiFi performance.

What Is a WiFi 7?

WiFi 7, technically called IEEE 802.11be Extremely High Throughput (EHT), is an upcoming generation of the 802.11 IEEE technical standards for the implementation of wireless local area network computer communication.

As the technical name suggests, the standard will deliver massive throughput gains when it becomes available, with speeds theoretically reaching up to 40 Gbps. That’s what the Thunderbolt 3 hardware interface can manage.

In comparison, the latest current WiFi standard, WiFi 6, has a maximum throughput of “just” 9.6 Gbps. In other words, WiFi 7 will be more than 4 times faster than WiFi 6.

The massive throughput increase will support the proliferation of the Internet of Things and enable new Augmented Reality ( AR ) and Virtual Reality ( VR ) applications.

But how is it possible for a new WiFi standard to be so much faster than the current WiFi standard? To answer this question, we must take a closer look at the new WiFi technologies behind it.

WiFi 7 vs WiFi 6

It’s very likely that your current WiFi router supports the 2.4 and 5 GHz frequency bands. Your future WiFi 7 router will also support the 6 GHz frequency band, which extends between 5.925 GHz and 7.125 GHz to offer a wide frequency range of 1,200 MHz.

To put the number into perspective, it’s important to realize that the range of the 2.4 GHz band is just 83.5 MHz (yes, MHz), while the range of the 5 GHz band is 700 MHz. As such, the 6 GHz band is wider than the 2.4 GHz and 5 GHz bands combined.

The massive width of the 6 GHz band not only makes it easier to send data at blazing-fast speeds, it also minimizes issues with signal interference, so your speeds won’t fluctuate wildly when other people in your area go online or when your roommate or spouse turns on the microwave oven.

More Advantages of WiFi 7

But that’s not all! The WiFi 7 standard will also likely support many new features, including:

• 320 MHz channel bandwidth: Thanks to the massive width of the 6 GHz band, WiFi 7 can use 320 MHz wide channels for massive throughput gains.
• Multi-link capabilities: The enhanced multi-link capabilities of the WiFi 7 standard make it possible to simultaneously broadcast in both the 5 GHz band and the 6 GHz band.
• Multi-Access Point (AP) coordination: Even the newest WiFi standards currently available don’t allow routers to intelligently communicate their channel settings to achieve the most efficient allocation of radio resources possible, but WiFi 7 will.
• Time-Sensitive Networking (TSN): This technology adds the ability to synchronize to a primary clock across the network for vastly improved low-latency transmission.
• 4096-QAM (4K QAM): WiFi can translate digital packets into an analog signal more efficiently thanks to its high QAM (Quadrature Amplitude Modulation).

Together, these and other features will deliver ground-breaking speeds and ensure great signal strength even in heavily congested areas.

Should I Upgrade to WiFi 7?

It’s important to clarify right away that the WiFi 7 standard hasn’t been finalized yet. A final version of the standard is expected to arrive in late 2023 or early 2024.

There’s currently only one WiFi 7 router on the market, the H3C Magic BE18000. This tri-band router is based on the latest draft of the WiFi 7 standard, so it may or may not be fully compatible with the final version.

Even if you decide to take the risk and buy the H3C Magic BE18000 router, you won’t really see any benefits over a comparable WiFi 6 router because there are no devices with WiFi 7 support currently on the market.

The good news is that leading chipset manufacturers like Qualcomm have already announced their intention to support the standard, with Qualcomm FastConnect 7800 becoming the world’s first WiFi 7 connectivity system.

Still, that doesn’t change anything about the fact that the WiFi 7 release date is still far in the future, so we recommend you wait until the standard is finalized and more WiFi 7 routers are available.

Until then, you can use a WiFi analysis tool like NetSpot to optimize the performance of your existing WiFi network.

Conclusion

WiFi 7 is not here yet, but it’s coming. When it arrives, it will usher in an era of Thunderbolt 3-level wireless speeds, enabling you to do the things you love to do online even more conveniently and using a whole new category of devices, such as augmented and virtual reality headsets.

What Is Wi-Fi 6? New Wi-Fi Names Explained

The Wi-Fi Alliance is renaming its Wi-Fi versions. Here’s why 802.11n, ac, and ax are becoming Wi-Fi 4, 5, and 6 and what you’ll see on routers and devices going forward.

I’m that 5G guy. I’ve actually been here for every «G.» I’ve reviewed well over a thousand products during 18 years working full-time at PCMag.com, including every generation of the iPhone and the Samsung Galaxy S. I also write a weekly newsletter, Fully Mobilized, where I obsess about phones and networks.

Wi-Fi has always had a bit of a branding problem. The ubiquitous wireless networking standard is set by the IEEE (the Institute of Electrical and Electronics Engineers) and uses the engineers’ arcane numbering system.

The original Wi-Fi standard was numbered 802.11, with speedier extensions getting letters at the end: 802.11a, 802.11b, 802.11g, and 802.11n. Eventually, with more amendments to 802.11 than letters, the engineers started wrapping around: 802.11ad isn’t the fourth addition to 802.11a, but an amendment of its own.

In any case, that’s always been confusing (is ac faster than n?) so finally, the Wi-Fi Alliancethe industry group that handles Wi-Fi certification and branding—has rebranded the speeds for consumers.

We’re now swapping letters for version numbers. There is no Wi-Fi 1, 2, or 3, formally, but there are places for those versions in Wi-Fi’s history. Here’s how the six current consumer standards will get renamed.

Old Name	New Name	Introduced	Max. Speed	Bands
802.11b	«Wi-Fi 1» (unofficial)	1999	11Mbps	2.4GHz
802.11a	«Wi-Fi 2» (unofficial)	1999	54Mbps	5GHz
802.11g	«Wi-Fi 3» (unofficial)	2003	54Mbps	2.4GHz
802.11n	Wi-Fi 4	2009	600Mbps	2.4GHz and 5GHz
802.11ac	Wi-Fi 5	2013	3.46Gbps	5GHz
802.11ax	Wi-Fi 6	2018/2019	10.53Gbps	2.4GHz and 5GHz

You’re likely to see these new names taking hold in 2019 and really becoming widespread in 2020. You’ll see the new numbering on routers, laptops, and other Wi-Fi devices going forward.

The Wi-Fi Alliance will try to get device makers to push people toward newer Wi-Fi devices by having user interface icons show the Wi-Fi level a device is connected to. So, if you get a Wi-Fi 6 router but all your devices are on Wi-Fi 4, you’ll see an icon that clearly shows you need to upgrade your devices to get better speeds.

Why do you want Wi-Fi 6, anyway? I wrote an explainer on what was once 802.11ax back in 2017. The details are still correct, except for the launch dates, which were too optimistic. In short, 802.11ax really improves performance in crowded Wi-Fi areas, where there are a lot of different networks or a lot of people on your network.

802.11ax access points started becoming available this summer, ahead of official certification, which is coming in 2019. There are no 802.11ax clients yet, but expect many 2019 mobile phones to support the standard.

Wi-Fi Alphabet Soup

The well-known forms of Wi-Fi aren’t the only versions of the 802.11 standard. The IEEE has had working groups on 802.11 back to the 1990s, and it’s currently working on amendments to the Wi-Fi standard that wouldn’t take effect before 2022. You can see all these amendments on the IEEE’s official timeline (Opens in a new window) . But here’s a quick rundown of what each one does and when it was approved.

Представлен обновлённый стандарт Wi-Fi 6 Release 2 с улучшенным качеством связи и пониженным потреблением энергии

Организация Wi-Fi Alliance объявила о выходе спецификаций стандарта Wi-Fi 6 Release 2, в котором усовершенствованы несколько функций, касающихся передачи данных и потребления энергии.

Стандарт Wi-Fi 6 Release 2 включает в себя все возможности существующего Wi-Fi 6, в том числе поддержку диапазонов 2,4 ГГц, 5 ГГц и 6 ГГц. Одним из важнейших достоинств нового протокола стала поддержка MU-MIMO (многопользовательский множественный вход / множественный выход) на восходящем канале. Роутеры традиционно отдавали предпочтение нисходящему каналу, предполагая, что пользователи компьютеров, смартфонов и устройств интернета вещей чаще скачивают данные из сети, а не выгружают их, однако в современных реалиях сценарии использования подключения эволюционируют, и приоритеты меняются.

Ещё одним нововведением стала оптимизация энергопотребления. Появилась поддержка технологии TWT (Target Wake Time), которая позволяет подключённым устройствам определять частоту активации для отправки или получения данных, в результате чего экономится заряд аккумуляторов. Поддерживается также метод динамического многопользовательского энергосбережения с пространственными мультиплексированием SMPS (Spatial Multiplexing Power Save) — он позволяет клиентским устройствам отключать приём избыточных данных. Эти решения позволили увеличить для устройств продолжительность работы в режиме сниженного энергопотребления.

Wi-Fi Alliance также привела данные компании IDC Research, согласно которым в 2022 году будут выпущены более 2 млрд устройств с поддержкой Wi-Fi 6. О поддержке Wi-Fi 6 Release 2 уже заявили крупнейшие представители индустрии, включая Broadcom, Infineon, Intel, MediaTek и Qualcomm.
