Wi-Fi 6 is the quickest customary but. Wi-Fi 6E will make it even higher

Speed is vital with Wi-Fi, and the class has definitely been transferring quick as of late. First got here Wi-Fi 6, a brand-new, faster version of Wi-Fi that began hitting the market in 2019. Now, after a unanimous vote in April, the Federal Communications Commission is opening up a whole new band of spectrum to accommodate next-gen units designed to faucet into it. Devices like these are already on their way by the tip of this 12 months.

Wi-Fi 6 vs. Wi-FI 6E: Here’s the distinction in three…

2:57

The Wi-Fi Alliance, an {industry} group that manages Wi-Fi nomenclature, branded this new spectrum and the units that may make the most of it underneath a brand new title: Wi-Fi 6E. One industry-funded report claims that, together with offering quicker speeds and new room for rising web visitors, the transfer will generate more than $180 billion in US revenue over the following 5 years.

The remainder of the world may be making ready to observe go well with. First up is the UK, the place regulators at Ofcom laid out the country’s own plan to expand Wi-Fi into the 6GHz band.

In different phrases, it has been a busy couple of years for Wi-Fi — and the arrival of Wi-Fi 6E may be essentially the most important growth but. Here’s some context that will help you wrap your head round it. 

Let’s speak 6GHz

Last 12 months, I wrote a post about Wi-Fi 6 that explains the brand new capabilities it brings to next-gen routers. In a nutshell, it is a quicker, extra environment friendly model of Wi-Fi that enables wi-fi entry factors like routers to higher handle networks crowded with a lot of customers and shopper units. My convoluted metaphor for all of that was to think about your router as a bartender, and the units in your community because the folks making an attempt to order drinks. A Wi-Fi 6 router is sort of a four-armed bartender able to effectively serving drinks to a number of patrons directly.

Enter Wi-Fi 6E. It is not a brand new model of Wi-Fi like Wi-Fi 6, however slightly a time period that identifies Wi-Fi 6 units which can be outfitted with the chips and radios wanted to function in that new mass of spectrum the FCC simply opened up. If a Wi-Fi 6 router is a greater bartender, then a Wi-Fi 6E router is a greater bartender with a brand-new bar, one with an unique shopper record and many room to work.

That new spectrum sits within the 6GHz band, a band that wasn’t beforehand allotted for unlicensed Wi-Fi use like the two.four and 5GHz bands already had been. So what’s so nice about 6GHz?

All about bandwidth

Time for one more metaphor!

Let’s say that you have a gallon of milk sitting in your kitchen counter representing all the spectrum of radio frequencies. You take a needle, jab it into the facet of the carton, after which pull it out. A really skinny stream of milk begins to jet out a number of toes. Then, you are taking one thing slightly thicker, like a nail, and poke one other gap into the facet of the container. More milk shoots out this time as a result of the opening is wider — however it would not go as far.

You can consider these two holes as the two.four and 5GHz bands. With a frequency vary of simply 70MHz, the two.4GHz band is the narrower of the 2. Like the needle-poked gap taking pictures milk throughout your kitchen, it could actually ship knowledge at an affordable distance, however with such a small opening, there is a restrict to how a lot it could actually ship. With 500MHz of bandwidth, the 5GHz band represents an even bigger gap within the milk carton. It can move extra knowledge directly — however it could actually’t ship it fairly as far.

That brings us to Wi-Fi 6E’s 6GHz band and its 1,200MHz of extra bandwidth. It’s such as you’ve punched a gap within the milk carton the scale of 1 / 4. Tons of milk comes gushing out, however it gushes downward and would not journey very far in any respect.

The takeaway is that the 6GHz band might be finest suited to close-range connections, ideally between units which can be in the identical room as each other. In conditions like that, the 2 units ought to be capable to move large quantities of knowledge backwards and forwards with the complete effectivity of Wi-Fi 6. We’ll sit up for testing connections like these (and their vary limitations) on the finish of this 12 months, when Wi-Fi 6E-compatible routers begin to arrive.

Extreme Networks’ Perry Correll, who sits on each the IEEE 11ax and Wi-Fi Alliance Wi-Fi 6 activity teams, means that the brief vary of the 6GHz band and its larger variety of channels is definitely “a tremendous advantage” in dense, difficult environments like transportation hubs, house items, sports activities arenas and enterprise complexes.

“If you’re sitting in a packed stadium with 70,000 other people, the arrival of Wi-Fi 6E means you’re not going to be competing for bandwidth in the same way you used to,” Correll says. “It will be significantly easier to stream the event to friends, order concessions via app, or even to find out which bathroom has the shortest lines.”

Wi-Fi’s VIP part

“AR/VR and gaming is another great use case for the 6GHz band,” Correll says. “Many do not realize the high-end VR sets that require the most bandwidth are actually tethered with cables. With Wi-Fi 6E, you not only get more bandwidth but cleaner bandwidth — meaning it is able to wirelessly provide the higher data rates required along with true mobility.”

Wi-Fi 6 is basically the important thing to that cleaner bandwidth, as a result of there will not be any earlier-gen Wi-Fi units which can be able to tapping into the 6GHz band. That implies that Wi-Fi 6E networks will not have any older-generation units appearing as weak hyperlinks within the chain.

Let’s return to that analogy I sketched out earlier. Like I mentioned, if Wi-Fi 6 makes your router into a greater bartender that may successfully serve a lot of patrons directly, then Wi-Fi 6E is the bar itself — and it is an unique, members-only sort of joint. The solely patrons ordering cocktails are Wi-Fi 6E patrons which can be able to being there, and all of them help Wi-Fi 6. 

In different phrases, no one’s casting any bizarre, confused appears on the four-armed bartender as he arms out drinks, as a result of they’ve all bought 4 arms, too. It is not as crowded or as noisy as different bars, and everybody’s outfitted to take full benefit of the bartender’s capabilities. It’s the quickest, best nightlife on the town.

So, I’ll want (one other) new router?

There’s the rub. Like that metaphorical bar’s exclusivity would possibly counsel, you may should be a member with a purpose to enter. Specifically, you may want Wi-Fi 6E units outfitted with new chipsets constructed to ship indicators within the 6GHz band.

Translation? Yes, you may want a brand new router — and new shopper units like telephones and laptops — with a purpose to take pleasure in the advantages of Wi-Fi 6E.

“We’re expecting the first set of devices to come to market in the second half of this year,” mentioned Vijay Nagarajan, vice chairman of promoting for Broadcom’s wi-fi communications and connectivity division. “You’ll see a whole slew of devices, both on the infrastructure side and on the client side, and much more in a much more accelerated manner in 2021.”

We’ve already seen one new router — the Asus ROG Rapture GT-AXE11000 gaming router — that boasts help for Wi-Fi 6E. That one hits shops in December.

Wi-Fi 6: What the heck is it?

6:57

That’s in all probability irritating for anybody who jumped in early and purchased a brand new Wi-Fi 6 router within the final 12 months, however do not be too arduous on your self. It’s nonetheless very early for Wi-Fi 6E, and the rollout will take a while. Wi-Fi 6 solely just lately penetrated the mainstream with public deployments and help from high-profile units just like the iPhone SE and the Samsung Galaxy S10. Devices like people who help Wi-Fi 6E are solely simply beginning to pop up on the radar. For occasion, new gaming telephones coming later this 12 months from Asus and Lenovo will use Qualcomm’s Snapdragon 865 Plus processor, which helps Wi-Fi 6E. They’ll be among the many first Wi-Fi 6E units available on the market, however most will not arrive till 2021.

In different phrases, that Wi-Fi 6 router that you simply purchased on Black Friday will proceed to be a top-of-the line entry level for one more 12 months or so, and it’ll proceed to be an excellent router after that, due to every little thing that Wi-Fi 6 brings to the desk. In reality, ready to improve till Wi-Fi 6E is extra extensively applied and polished may be the very best method. At that time, we’ll have a greater sense of the type of customers who stand to profit essentially the most from the improve, and so they’ll have a better time discovering a very good deal, too.

More excellent news: Your older-gen Wi-Fi devices will nonetheless work with routers that help Wi-Fi 6E, as a result of Wi-Fi 6 is totally backward-compatible with earlier variations of Wi-Fi. They simply will not be capable to function in that unique 6GHz band.
