What is Wi-Fi 7 and Why do we need it?

Wi-Fi technology has just been pushing the envelope for the past few years. While most of us are still using Wi-Fi 5, the Wi-Fi Alliance has already released two new Wi-Fi versions in the last three years: Wi-Fi 6 and Wi-Fi 6E. Even more so, the IEEE 802.11be standard, or Wi-Fi 7, is already being developed by companies like Qualcomm and MediaTek with the help of the Wi-Fi Alliance. However, what exactly is 802.11be? Is it necessary? Learn much more about new Wi-Fi standard by reading on.

What is Wi-Fi 7? When we can expect it?

Wi-Fi 7 will be the next generation of Wi-Fi technology, following Wi-Fi 6E, in terms of simple terms. Wi-Fi 7 has been given the technical IEEE term IEEE 802.11be EHT, which stands for Extremely High Throughput, just like every other Wi-Fi version. Since the technology is still being developed, it isn’t available to the general public just yet. Wi-Fi 7 won’t be available until the middle of 2024, according to an IEEE study on the current status of the 802.11be wireless communication standard.

Despite the fact that Wi-Fi 7 is still a few years away, many of its features and advancements have been revealed. To be sure, these features seem to be subject to change in the near future as new technology is created. Let’s now take a look at some of Wi-Fi 7’s most important features.

Wi-Fi 7: Key Features and Advancements

  • Extremely High Throughput” : Wi-Fi 7 promises speeds up to 30 Gbps, in accordance with the “Extreme” moniker. The Wi-Fi 6E standard’s maximum speed is 9.6 Gbps, which is almost three times as fast as this. A large number of industry experts believe that the tripled Wi-Fi speeds can’really’ replace Ethernet and cables internet connections.
  • Improved speed and overall performance: Wi-Fi 7 will use a variety of tricks to get the most out of the available bandwidth. As a result of the IEEE 802.11be EHT, the Wi-Fi 6E standard’s full 6 GHz band will finally be utilized. It will also use 320 MHz single-channel bandwidth, rise from 160 MHz in Wi-Fi 6E, which will result in faster speeds and more “space” for your device.

  • Low latency: The internet devices are linked to your Wi-Fi router will no longer interfere with each other due to the full use of the 6GHz band. There is less competition for faster internet speeds because your devices are given more storage space. With the addition of Multi-Link Operation (MLO), devices will be able to stay online utilising multiple active Wi-Fi bands simultaneously. Due to all of this, Wi-Fi 7 should have virtually no latency.
  • In other words, when Wi-Fi 7 arrives : we can predict even better mesh Wi-Fi systems thanks to IEEE 802.11be, which is expected to improve access point coordination. The goal is to maintain a stable Wi-Fi connection even when the user is roaming and still provide them with fast internet.
  • The new Wi-Fi standard : will not really mean that your older devices would become obsolete. An IEEE draft on Wi-Fi says that Wi-Fi 7 will support all devices operating at 2.4GHz or higher and will be the next generation of Wi-Fi. Even if your device does not support the new Wi-Fi standard natively, it will be capable of connecting to a Wi-Fi 7 router without any problems.

Do we really need Wi-Fi 7? and Why?

There are a lot of exciting new features and advancements in Wi-Fi 7, but the question remains: Do we really need Wi-Fi 7? What’s the solution? Do I think so? Wi-Fi 6E is more than adequate for both home and office use in the current climate. But if you’re running a private data center out of your house, I can’t think of a situation where you’d need a 30 Gbps connection right now.

In comparison to the fastest available commercial Ethernet cable, Wi-Fi 6E can produce speeds of up to 9.6 Gbps. The standard should be able to handle whatever you pass at it at this point in time. Wi-Fi 7 will ultimately be a requirement for all of us due to the growing number of devices we use on a daily basis, including such smartwatches, IoT products, and so on.

While the idea of your 5G-connected car being controlled by your Wi-Fi 7-connected smartwatch seems far-fetched today, the Wi-Fi Alliance is working to ensure that the necessary network infrastructure is in place.
