What are the changes in Wi-Fi 7 compared to Wi-Fi 6?

Dec 10, 2021
Currently, Wi-Fi 7 brings improvements over Wi-Fi 6e in terms of speed, which is 2.4 times faster if the same number of antennas are used on Wi-Fi 7 products as on Wi-Fi 6e.
The Wi-Fi 7 standard will also significantly reduce latency, which will help improve application experiences that are important every millisecond, such as games.
However, the Wi-Fi Alliance is still "in the early stages of the Wi-Fi 7 standardization process" and there is no way to say exactly when the Wi-Fi 7 standard will be finalized.
It is rumored that the Wi-Fi 7 standard is expected to be "released in the second quarter of 2022".
According to this schedule, the technology is expected to be available in 2023.
Huawei has the largest number of Wi-Fi 7 technologies in the world, surpassing Qualcomm and Intel.

According to Huawei, the new generation of WiFi 7 will be unveiled in 2022.

Huawei's website shows that Huawei is constantly expanding more WiFi 7 related technologies. Compared with WiFi 6, the new WiFi 7 channel has a bandwidth of up to 320MHz and the highest transmission rate up to 30Gbps.
WiFi 7 (Wi-Fi 7) is the upcoming next-generation Wi-Fi standard, also known as IEEE 802.11bemuri-it has ultra-high throughput (EHT).
Based on Wi-Fi 6, Wi-Fi 7 introduces technologies such as 320MHz bandwidth, 4096 orthogonal amplitude modulation (QAM), multi-resource unit (RU), multi-link operation (MLO), enhanced multiuser multiplexing and so on.
Input multiple output (MU-MIMO) and multiple access points (AP) coordination.
With these cutting-edge technologies, Wi-Fi 7 provides higher data rates and lower latency than Wi-Fi 6.
Wi-Fi 7 is expected to support up to 30 Gbps of throughput, about three times that of Wi-Fi.

Last week, EDN Electronic Technology Design also reported that "MediaTek's preview Wi-Fi V7 technology demonstration is 2.4 times faster than that of the Wi-Fi 6e."
Why do we need Wi-Fi 7?
With the development of WLAN technology, families and enterprises rely more and more on Wi-Fi for network access.
In recent years, emerging applications have put forward higher requirements for throughput and delay.
Typical examples of these applications include 4K and 8K video (involving transmission rates of up to 20 Gbps), virtual reality (VR) / augmented reality (AR), online games (requiring latency of less than 5 milliseconds), telecommuting, online video conferencing, and cloud computing.
In the face of such high requirements, Wi-Fi 6mura-the latest Wi-Fi standard-is not enough despite its efforts to improve the user experience in high-density scenarios.
As a result, IEEE is about to release a new amendment called IEEE 802.11be EHT, also known as Wi-Fi 7.
Wi-Fi 7 release time.
The IEEE 802.11be Task Force (TGbe) was officially established in May 2019, dedicated to the development of 802.11be (Wi-Fi 7).
The standard will be available in versions 1 and 2.
TGbe plans to release draft 1.0 of 802.11be in 2021, and version 1 will be available by the end of 2022.
Version 2 is expected to be launched in early 2022 and released by the end of 2024.
Wi-Fi 7 and Wi-Fi 6.
Wi-Fi 7 is based on the Wi-Fi 6 standard and introduces a number of new technologies.

Wi-Fi 6 and Wi-Fi 7 are compared below.
