What is Wi-Fi 7? Everything You Need to Know About the Next Wireless Standard


Whereas many individuals solely just lately upgraded to Wi-Fi 6, and a few could also be contemplating a soar to Wi-Fi 6E, their successor is already on the horizon. Wi-Fi 7 is the subsequent vital advance, and, identical to its predecessors, the brand new commonplace guarantees sooner connections, decrease latency, and the power to gracefully handle extra connections than ever earlier than.

In case you are seeking to improve your Wi-Fi immediately, Wi-Fi 7 shouldn’t be the reply, as a result of assist can be scarce for a while to come back. However early adopters can be excited by the information that the primary batch of Wi-Fi 7 routers is about to land in early 2023. Realistically, will probably be a very good whereas earlier than most of us ought to think about switching. If you could improve pronto, first think about delving into how to buy a router earlier than you try our picks of the best Wi-Fi routers and the best mesh Wi-Fi systems.

Up to date November 2022: We adjusted the timeline as Wi-Fi 7 attracts nearer and added information about TP-Hyperlink’s Wi-Fi 7 router lineup.

What’s Wi-Fi 7?

The seventh era of Wi-Fi guarantees main enhancements over Wi-Fi 6 and 6E and will provide speeds as much as 4 instances sooner. It additionally consists of intelligent advances to scale back latency, enhance capability, and enhance stability and effectivity.

Wi-Fi 7 is IEEE 802.11be within the outdated naming conference, the place Wi-Fi 6 was IEEE 802.11ax, and Wi-Fi 5 was IEEE 802.11ac. Like earlier requirements, Wi-Fi 7 can be backward suitable. However to make the most of the brand new options and improved efficiency it guarantees, you have to to improve your gadgets. Meaning shopping for new routers and entry factors, to not point out new smartphones, laptops, TVs, and so forth.

What Advantages Will Wi-Fi 7 Deliver?

Wi-Fi 7 can be sooner, assist extra connections, and be extra adaptive to take care of dependable low latency efficiency.

These advantages will assist ship high-quality video and higher cloud gaming, and they’ll serve AR and VR functions that require excessive throughput and low latency. Wi-Fi 7 additionally tackles congestion and interference, bringing tangible advantages to areas with densely packed gadgets or neighboring networks that overlap. The latter is most vital for the enterprise and bigger venues.

How Does Wi-Fi 7 Evaluate to Wi-Fi 6E?

You might, understandably, surprise what distinguishes Wi-Fi 7 from Wi-Fi 6E, which broadly guarantees the identical benefits over earlier requirements by opening up the 6-GHz band. Particularly since Wi-Fi 7 will use the identical three 2.4-GHz, 5 -GHz, and 6-GHz bands. Listed here are some notable upgrades.

Wider Channels

Every band is damaged into channels. The two.4-GHz band includes 11 channels of 20 megahertz (MHz) every. The 5-GHz band has 45 channels, however as an alternative of being restricted to a width of 20 MHz, they will mix to create 40-MHz or 80-MHz channels. The 6-GHz band helps 60 channels, and with Wi-Fi 6E they are often as extensive as 160 MHz. Wi-Fi 7 helps channels which might be as much as 320 MHz extensive. The broader the channel, the extra information it could transmit.

A easy analogy is to think about how a lot visitors a single-lane highway can deal with in comparison with a three-lane freeway or a six-lane superhighway.

Greater QAM

Quadrature Amplitude Modulation (QAM) is a technique to transmit and obtain information in radio-frequency waves. The upper it’s, the extra info you possibly can pack in. Wi-Fi 7 helps 4K-QAM, Wi-Fi 6 supported 1024-QAM, and Wi-Fi 5 was restricted to 256-QAM.

The potential advantages are sophisticated by sign energy, background noise, and interference. Consequently, as QAM goes up, the vary drops, and also you want a stronger sign. So, the soar to 1024-QAM in Wi-Fi 6 supplied round a 25 % information charge enhance over Wi-Fi 5. The leap to 4K-QAM in Wi-Fi 7 interprets to a 20 % enhance in peak efficiency.

Multi-Hyperlink Operation

Maybe essentially the most thrilling advance in Wi-Fi 7 is Multi-Hyperlink Operation (MLO). Each earlier Wi-Fi commonplace establishes a connection between two gadgets on a single band. Even a tri-band Wi-Fi 6E router connects two gadgets on a single band on a hard and fast channel (the router decides whether or not to attach on the two.4-GHz, 5-GHz, or 6-GHz band).

MLO can mix a number of frequencies throughout bands right into a single connection. A Wi-Fi 7 router can hook up with a Wi-Fi 7 gadget throughout two or extra channels in several bands concurrently. MLO doubtlessly allows wider channels able to transmitting extra information—going again to our freeway analogy, you possibly can ship visitors on the freeway and the superhighway directly.

Pace isn’t at all times the precedence, however MLO additionally permits for extra environment friendly efficiency. A Wi-Fi 7 router can take congestion and different interference under consideration and transmit on one of the best channel to bypass it, switching to take care of a secure connection and low latency. MLO may additionally assist mitigate the comparatively brief vary of the 6-GHz band.
