What is Wi-Fi 7? Here’s everything we know about the future standard

It may seem strange to talk about a Wi-Fi 7 standard. The Wi-Fi 6 standard has barely arrived yet — in fact, its final authorized form is still expected to be announced at the end of 2019. Few devices on the market are even ready for it. Wi-Fi 7 is, at the best, still several years away.

But thanks to interviews with Qualcomm’s VP of technology, V.K. Jones, we have some idea of what this future Wi-Fi standard will look like, and what’s exciting about it. As we all start embracing Wi-Fi 6, here’s how wireless networks are going to get even better in the future.

When is it coming?

According to Qualcomm, the release date of Wi-Fi 7 is likely to be 2024, with a lead up of major improvements to the Wi-Fi standard starting in 2020.

Of course, this is partially conjecture. Qualcomm no doubt knows enough to make a good estimate, but the actual date depends on when the Wi-Fi Alliance finalizes the standard and, ultimately, how the technology progresses. It’s safe to say that a mid-2020s date is likely.

Will it be called Wi-Fi 7?

We don’t know yet, but it’s likely. The current standard, 802.11ax, was officially labeled “Wi-Fi 6” because the creators wanted to simplify standard naming and keep people from getting confused between 802.11ax, 802.11ax, and others. So it makes sense to keep this new naming convention and call the next massive standard update Wi-Fi 7.

Qualcomm’s reasoning is that the improvements expected by around 2024 will be enough to warrant the Wi-Fi 7 label. Developers are already referring to it as “802.11be,” although this more technical title has also not been officially given.

Three stages of development

Wi-Fi 6 has already provided massive increases in speed and great improvements in quality of life, showing speeds two or three times greater than Wi-Fi 5. How can Wi-Fi 7 improve on that? Well, Qualcomm is forecasting three important stages of changes that we can expect, culminating in the release of Wi-Fi 7.

Stage 1 – The 6GHz band

This is more like a big upgrade to Wi-Fi 6, but it paves the way for a lot of exciting stuff. Today’s Wi-Fi devices are authorized to use the 2.4GHz and 5GHz bands (some devices use a secondary section of the 5GHz band, which is where terms like “triple-band router” come from). However, government agencies in Europe and the United States are working to authorize sections of the 6GHz band for Wi-Fi use as well, specifically for Wi-Fi 6 and later technologies.

Providing that governments and telecoms can work out the details, the 6GHz band will be excellent for offering high-speed Wi-Fi in spread-out spaces — think stadiums or college campuses. Home routers may become truly tri-band as well. This is expected to begin sometime in 2020.

Stage 2 – Uplink technology

The next big upgrade is expected to bring better uplink capabilities through an advanced form of MU-MIMO that will be called UL MU-MIMO. MU-MIMO creates individual connections with multiple devices at the same time, instead of one connection that rotates between devices very quickly—the result is high-quality connections with fewer problems and better apparent speeds for downloading data. UL MU-MIMO is a secondary upgrade that improves the process of uploading data, completing the back half of MU-MIMO.

Basically, this means that Wi-Fi tech will take another jump in quality, especially when it comes to livestreaming and sharing rich media like videos. It’s expected to work with up to eight simultaneous users at once. Qualcomm has a slideshow that goes into a little more depth if you’re curious. This MU-MIMO upgrade is predicated to happen around 2022.

Stage 3 – The big 802.11be upgrade

Stage 3 is expected to be a larger overhaul worth of a new standard, which the other changes would have laid the proper groundwork for in preceding years. These improvements would make a number of important changes, notably:

  • CMU-MIMO: This is a very ambitious project that essentially allows mesh networking between all kinds of antennas to enable widespread MU-MIMO connections. These antennas could be located anywhere – on other routers, on separate devices, on desktops, etc. They would all work together to manage as many connections as possible. Even Qualcomm admits that there’s a fair chance this technology won’t ultimately be possible, but it would be very cool.
  • Multi-band data management: By this time, the average router will have access to three fully separate bands – 2.4, 5, and 6GHz. This part of 802.11be would allow networks to send data across two or three of these bands simultaneously, but ensuring they all arrive and recombine at their destination. Because of the way data packets work, using multiple bands at once for a transmission could greatly increase Wi-Fi speeds. In fact, some experts are predicting that around this time Wi-Fi could become even faster than wired connections, which is also very ambitious.
  • Better modulation and compression: Each Wi-Fi standard improves how data is sent across radio bands, allowing signals to send more data, faster. This upgrade would be no exception.

Compatible devices

Manufacturers are still preparing to ship devices compatible with Wi-Fi 6. It’s far too early to start talking about Wi-Fi 7 devices when we’re not even sure what the new standard would bring to the table. However, if Qualcomm’s expectations are correct, Wi-Fi 7 could be an even larger change than Wi-Fi 6, and require more hardware upgrades than ever before.

That means not only new routers, but also compatibility with devices such as smartphones and laptops.

How much data does video streaming use?

When it comes to internet usage, video watching is one of the main interests of users. Most users are mainly inclined towards streaming videos so it matters a lot to know how much data is required for it. Of course, we do require a smooth internet connection to be able to stream our favorite content online.If video streaming is your preference then you must consider high-speed internet like Spectrum internet for instance, that do not offer data caps. This means you do not have to worry about any extra fee surprises in your bill that are bound to happen if you run out of your data limit. Most of the providers in the United States do impose data caps so it is very important to find out an internet plan that assures a no data cap policy. For that, let us first have a look at the data that is needed for various video streaming platforms.YouTubeJust like using any other app on your smartphone, YouTube being one of the popular platforms needs data too. It nearly takes 562.5 MB of data per hour. This holds valid when you stream at around 480p resolution. In case you want better resolution, then you might require 1.86 GB per hour for 720p. For 1080p you might require 3.04 GB. For watching videos in 4K, you will require a massive 15.98 GB of data per hour.NetflixWe all agree with the fact that how much we love Netflix as it has successfully evolved as one of the most popular video streaming services. For subscribers exceeding 130 million, the internet speed is not much of a problem. An hour of video streaming in standard definition would need around 1 GB of data. If you want to enjoy high-quality video streaming, you might need up to 3GB. For ultra-high-definition, you can require up to 7 GB of data per hour.The selection of accounts can help you decide a suitable resolution for your connection. If you want to save your data, you can check the settings option and click the save button when you want.Amazon Prime VideoAmazon Prime Video was launched by Amazon as a streaming service in 2011 and has ever gained popularity among the users. Nowadays it is seen as one of the biggest competitors for Netflix. This service provides up to three resolutions for the users. Among them include good, better, and best. The Good enables streaming videos at around 480p in standard definition and utilizes a data of 800 MB per hour. The Better option allows an HD stream with a data requirement of around 2 GB per hour. The Best option consumes nearly 6 GB of data per hour. You should also know that accessing Amazon Prime Video on your mobile app results in low data consumption as compared to the desktop app.HuluHulu is another important video streaming option that uses somewhat less data as compared to Netflix and Amazon Prime Video This makes Hulu as one of the most economical options available. You require around 680 MB per hour of data for the standard definition. If you switch to a 720p high definition setting, the data requirement may jump to 1.3 GB per hour. 1080p resolution can need data up to 2.7 GB per hour. You can also stream live TV if you are using Hulu’s $39.99 monthly plan.SpotifySpotify is one of the best-known music streaming platforms but not everyone knows that it also provides a video service in certain areas. The company does not disclose much about the data requirements of the video streaming service. However it only notifies that video streaming requires more data as compared to music streaming and is much like the ones needed for other video channels. Mostly the videos are in high definition and can consume up to 3 GB of data for an hour streaming.VimeoVimeo does not have any details regarding data usage. The standard definition content can need up to 353 MB of data per hour. As far as the HD videos are concerned, they need up to 2.75 GB per hour.StanMany of us might not have heard of Stan as it is accessible in Australia only. The app usually provides four-tier quality. The lowest standard definition setting can require up to 1.13 GB per hour while HD and 4K can require around 3 GB per hour and 7 GB per hour respectively.DirecTVThe DirecTV website also does not display clear information about the required bandwidth. In case if your provider puts a data limit, you can always reduce your video quality. The data consumption parallels to the aforementioned video streaming platforms.Sling TVSling TV is another one of the highest quality video streaming service that uses around 2 GB per hour of data for its highest quality option. The data required for medium quality is 540 MB per hour that further lowers to 360 MB per hour for low-quality streaming options.Summing UpYou need to be aware of the data consumption involved in the video streaming service you are using. This can save you from exceeding your data limit and paying any additional cost.EDITOR NOTE: This is a promoted post and should not be viewed as an editorial endorsement.
