Each WIRED reader is conversant in that fixed query: Wait for brand spanking new expertise, or purchase now? Irrespective of how good a gadget is, there’ll nearly definitely be one thing higher arriving quickly. Producers work out the kinks and costs fall. Determining which new applied sciences are well worth the early adopter tax, and which to go on till they enhance, is an actual problem. 

Even purchasing for one thing as utilitarian as a Wi-Fi router is a minefield. Wi-Fi 6 is a straightforward minimal suggestion for most people proper now. However maybe you might be eyeing the improved pace and efficiency of the newly opened 6-GHz band. It’s possible you’ll be contemplating a Wi-Fi 6E system, however with Wi-Fi 7 on the horizon, do you have to wait?

When you purchase one thing utilizing hyperlinks in our tales, we might earn a fee. This helps assist our journalism. Be taught extra.

The Hassle With Wi-Fi 6E

When you want a greater understanding of the variations, we now have guides on Wi-Fi 6, Wi-Fi 6E, and Wi-Fi 7 that dig into the small print. However for our functions right here, we’re trying on the opening up of the 6-GHz band. Till Wi-Fi 6E got here alongside, we relied upon the two.4-GHz and 5-GHz bands for all our Wi-Fi wants. Wi-Fi 6E opened up the 6-GHz spectrum for the primary time, however there are restrictions in place that restrict its efficiency. 

We spoke to Kevin Robinson, CEO of Wi-Fi Alliance, to seek out out extra. When the FCC gave permission to make use of the unlicensed 6-GHz band for Wi-Fi, it had issues about potential interference for present license holders. Utilities and emergency providers depend on microwave hyperlinks and different wi-fi connections on the 6-GHz band for issues like energy grid operations. It’s also used for satellite tv for pc hyperlink communications, wi-fi backhaul for carriers, and by some broadcasters. To mitigate these issues, the FCC specified that Wi-Fi 6E techniques could be restricted to low-power indoor operation. (Notice that these guidelines range from nation to nation, relying on the physique in cost.) 

By proscribing energy for Wi-Fi 6E techniques, the brief vary of the 6-GHz band is ensured, primarily proscribing it to indoor use. The sign is blocked by partitions, so there’s little or no threat of any interference for incumbents. The issue is that this energy restriction successfully curtails the 6-GHz band.

We have now examined a number of Wi-Fi 6E routers and mesh techniques, and whereas they permit for some impressively quick and steady connections, the vary of the 6-GHz band could be very restricted. Count on lightning-fast connections in the identical room because the router, however transfer subsequent door or upstairs and so they drop off sharply or hand you over to the 5-GHz band. 

Getting the Most from Wi-Fi 6E

Regardless of the constraints, Wi-Fi 6E does supply advantages over Wi-Fi 6, however solely in sure situations. Most people don’t have many gadgets that may join on the 6-GHz band. The present checklist consists of current Samsung Galaxy S telephones and Google Pixels, however not Apple’s iPhones, although Apple has added 6E assist to the newest MacBook Execs and iPad Execs. There’s additionally no 6E assist within the newest consoles, and it’s nonetheless scarce in laptops and computer systems outdoors the newest top-of-the-line fashions. 

When you go for a single Wi-Fi 6E router, bear in mind which you can solely benefit from the 6-GHz band when your related gadgets assist 6-GHz and are inside vary. For instance, you have got the router in your house workplace and a smartphone and laptop computer that assist Wi-Fi 6E. The hazard with a tri-band router is that you just not often have something related to the 6-GHz band. For most individuals, a tri-band system with one 2.4-GHz and two 5-GHz bands will work simply as nicely, and doubtless higher, than a system with a 2.4-GHz, 5-GHz, and 6-GHz band.
