What Is Wi-Fi 7? Here’s Everything You Need to Know About the Next Wireless Standard Leave a comment

Whereas many individuals solely lately upgraded to Wi-Fi 6 or Wi-Fi 6E, the successor to these requirements has already arrived. Wi-Fi 7 is the subsequent vital advance, and similar to its predecessors, it guarantees sooner connections, decrease latency, and the flexibility to gracefully handle extra connections.

In case you are trying to improve your Wi-Fi at present, Wi-Fi 7 just isn’t the reply, as a result of assist might be scarce. However early adopters might be excited by the information that the Wi-Fi Alliance has unveiled the “Wi-Fi 7 Licensed” program. Realistically, it will likely be a very good whereas earlier than most of us ought to think about switching. If it’s good to improve pronto, first think about delving into how to buy a router earlier than you take a look at our picks of the best Wi-Fi routers and the best mesh Wi-Fi systems.

Up to date January 2024: We added information of the Wi-Fi 7 Licensed program and up to date particulars of the specs and our experiences with early Wi-Fi 7 mesh programs and routers.

What’s Wi-Fi 7?

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

Wi-Fi 7 is IEEE 802.11be within the previous 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 might be backward appropriate. However to make the most of the brand new options and improved efficiency it guarantees, you have to to improve your gadgets. Which means shopping for new routers and entry factors, to not point out new smartphones, laptops, TVs, and so forth.

What Advantages Does Wi-Fi 7 Deliver?

Wi-Fi 7 is quicker, helps extra connections, and is extra adaptive to take care of dependable low-latency efficiency.

These advantages assist ship high-quality video and higher cloud gaming, they usually 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 enterprise and bigger venues.

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

It’s possible 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 here are some notable upgrades:

Wider Channels

Every band is damaged into channels. The two.4-GHz band contains 11 channels of 20 megahertz (MHz) every. The 5-GHz band has 45 channels, however as a substitute 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 huge as 160 MHz. Wi-Fi 7 helps channels which are as much as 320 MHz huge. The broader the channel, the extra knowledge it may well 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.

Multi-Hyperlink Operation

Maybe probably the most thrilling advance in Wi-Fi 7 is Multi-Hyperlink Operation (MLO). Each earlier Wi-Fi normal 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 system throughout two or extra channels in numerous bands concurrently. MLO probably allows wider channels able to transmitting extra knowledge—going again to our freeway analogy, you’ll be able to ship visitors on the freeway and the superhighway directly.

Velocity 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 into consideration and transmit on the most effective channel to bypass it, switching to take care of a steady connection and low latency. MLO may assist mitigate the comparatively brief vary of the 6-GHz band, guaranteeing you get seamless connectivity out of your mesh system as you progress across the house.

Greater QAM

Quadrature Amplitude Modulation (QAM) is a technique to transmit and obtain knowledge in radio-frequency waves. The upper it’s, the extra data you’ll be able to pack in. Wi-Fi 7 helps 4K-QAM, whereas Wi-Fi 6 supported 1,024-QAM, and Wi-Fi 5 was restricted to 256-QAM.

The potential advantages are difficult 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 1,024-QAM in Wi-Fi 6 provided round a 25 p.c knowledge price enhance over Wi-Fi 5. The leap to 4K-QAM in Wi-Fi 7 interprets to a 20 p.c enhance in peak efficiency.
