What is Wi-Fi 7? Everything You Need to Know

Whereas many individuals solely just lately upgraded to Wi-Fi 6, and a few could also be contemplating a leap 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 customary guarantees quicker connections, decrease latency, and the flexibility to gracefully handle extra connections than ever earlier than.

In case you are seeking to enhance your Wi-Fi at this time, Wi-Fi 7 just isn’t the reply, as a result of assist will probably be scarce for a while to come back. However early adopters will probably be excited by the information that the primary batch of Wi-Fi 7 routers is ready to land in early 2023. Realistically, it will likely be a very good whereas earlier than most of us ought to think about switching. If you might want to improve pronto, first think about delving into the way to purchase a router earlier than you take a look at our picks of the perfect Wi-Fi routers and the perfect mesh Wi-Fi programs.

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 supply speeds as much as 4 instances quicker. It additionally contains intelligent advances to scale back latency, improve 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Wi-Fi 7 is IEEE 802.11be within the outdated naming conference, the place Wi-Fi 6 was IEEE 802.11ax, and Wi-Fi 5 was IEEE 802.11ac.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 will probably be backward appropriate. However to make the most of the brand new options and improved efficiency it guarantees, you have to to improve your units. 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 Carry?

Wi-Fi 7 will probably be quicker, 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’re going to serve AR and VR purposes that require excessive throughput and low latency. Wi-Fi 7 additionally tackles congestion and interference, bringing tangible advantages to areas with densely packed units 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?

Chances are you’ll, understandably, marvel 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 below 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’ll 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 large as 160 MHz. Wi-Fi 7 helps channels which are as much as 320 MHz large. The broader the channel, the extra information it may transmit.

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

Larger 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 power, background noise, and interference. Consequently, as QAM goes up, the vary drops, and also you want a stronger sign. So, the leap to 1024-QAM in Wi-Fi 6 supplied round a 25 % information price improve over Wi-Fi 5. The leap to 4K-QAM in Wi-Fi 7 interprets to a 20 % improve 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 customary establishes a connection between two units on a single band. Even a tri-band Wi-Fi 6E router connects two units on a single band on a set 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 connect with a Wi-Fi 7 system throughout two or extra channels in numerous bands concurrently. MLO doubtlessly permits wider channels able to transmitting extra information—going again to our freeway analogy, you possibly can ship visitors on the freeway and the superhighway without delay.

Pace isn’t all the time 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 the perfect channel to bypass it, switching to take care of a steady connection and low latency. MLO may additionally assist mitigate the comparatively brief vary of the 6-GHz band.
