What is Wi-Fi 7 802.11be and do we really need it?

Supply: Pocketnow

For the previous few years, Wi-Fi expertise has been pushing its boundaries. Whereas most of us depend on Wi-Fi 5 for our day-to-day use, the Wi-Fi Alliance has already rolled out two Wi-Fi variations, 6 and 6E, up to now three years alone. What’s extra, Wi-Fi Alliance is already working with firms like Qualcomm and MediaTek on the subsequent technology of Wi-Fi commonplace often known as IEEE 802.11be, or generally referred to as Wi-Fi 7. However what’s Wi-Fi 7 802.11be? Do we actually want it? Learn alongside and be taught extra in regards to the upcoming Wi-Fi commonplace.

What’s Wi-Fi 7? When will it’s accessible?

In easy phrases, Wi-Fi 7 is the subsequent technology of Wi-Fi expertise after Wi-Fi 6E. Like each different Wi-Fi model has a technical IEEE time period, Wi-Fi 7 has been given the time period IEEE 802.11be EHT, during which EHT stands for Extraordinarily Excessive Throughput. The expertise is at the moment being labored on and isn’t but accessible anyw. on this planet. As per the IEEE’s analysis paper on the present standing of the event of 802.11be wi-fi communication commonplace, Wi-Fi 7 will solely be accessible in mid-2024.


Although the expertise is a few years away proper now, a whole lot of options and developments that we will count on from Wi-Fi 7 have already been revealed. Nonetheless, because the expertise is being developed proper now, these options are topic to alter. Let’s now have a look at the important thing options we will count on from Wi-Fi 7.

Wi-Fi 7: Key Options and Developments

  • Sooner Speeds: Adhering to the “Extraordinarily Excessive Throughput” moniker, Wi-Fi 7 guarantees speeds as much as 30 Gbps. That is virtually thrice the utmost pace supplied by the Wi-Fi 6E commonplace, i.e., 9.6 Gbps. Due to the tripled Wi-Fi speeds, many business professionals are of the opinion that Wi-Fi 7 might ‘realistically’ exchange Ethernet and wired web connections.

  • Full use of 6GHz bandwidth and fewer interference: Wi-Fi 7 will use quite a lot of methods to enhance the pace and total efficiency. The IEEE 802.11be EHT will lastly make use of the total 6 GHz band that first got here with the Wi-Fi 6E commonplace. Furthermore, Wi-Fi 7 will use 320 MHz single-channel bandwidth, up from 160 MHz in Wi-Fi 6E, leading to elevated pace and extra ‘house’ in your system.

  • Low latency: Due to the total use of the 6GHz band, the web gadgets related to your Wi-Fi router is not going to intrude with one another anymore. In easy phrases, your gadgets can have more room, and thus, they will not compete with one another for sooner web. Along with the usage of a 6GHz Wi-Fi band, Multi-Hyperlink Operation (MLO) expertise will enable gadgets to be saved on-line utilizing a number of lively bands on the identical time. Because of all this, Wi-Fi 7 ought to just about supply no delay in any respect.

  • Higher and sooner mesh Wi-Fi techniques: IEEE 802.11be can even reportedly carry higher coordination between entry factors, which in easy phrases implies that we will count on even higher Wi-Fi mesh techniques when Wi-Fi 7 is .. The thought is to offer customers with as quick web as doable with out the person noticing any change within the Wi-Fi connection, even after they’re roaming.

  • Backward compatibility: Newer Wi-Fi commonplace doesn’t suggest your outdated gadgets will turn into out of date. As a substitute, the present IEEE draft on Wi-Fi commonplace states that each one the at the moment help Wi-Fi gadgets, from 2.4GHz to 6GHz, can be supported in Wi-Fi 7. Your system will be capable to connect with a Wi-Fi 7 router with none problem, even when it does not natively help the brand new Wi-Fi commonplace.

So, do we actually want Wi-Fi 7?

All of the developments and options of Wi-Fi 7 sound very fascinating, however then it begs the query: Do we actually want Wi-Fi 7? The reply? Sure and no. Properly, within the present state of affairs, Wi-Fi 6E is greater than sufficient for residential and workplace use. I can not actually consider a state of affairs (proper now) w.in you’d require a 30 Gbps connection except you are working a small-scale information heart in your own home.

Wi-Fi 6E can ship speeds of as much as 9.6 Gbps which is nearly the pace of the quickest commercially accessible Ethernet cable. The usual can in all probability deal with every little thing you throw at it proper now. Nonetheless, with the rising variety of gadgets in our every day lives, corresponding to smartwatches, IoT merchandise, and whatnot, and lots of future AR, VR, and MR merchandise within the pipeline, Wi-Fi 7 will ultimately be a requirement for all of us.

The world w. your Wi-Fi 7 related smartwatch will be capable to management your 5G-connected automobile sounds very unreal proper now, but it surely’s the route we’re shifting in, and the Wi-Fi Alliance group is ensuring that the community infrastructure is prepared for it.
