Wi-Fi 7 is already here before Wi-Fi 6 is used?

On April 19, although Wi-Fi 6 is being widely popularized and it has become a consensus that many new 5G products support the Wi-Fi 6 protocol, there is still a long way to go before Wi-Fi 6 can be actually popularized. Recently, some media reported that the seventh-generation Wi-Fi 7 technology has been arranged, and it is said that the maximum speed of Wi-Fi 7 can reach 30Gbps.

Users who are familiar with Wi-Fi 6 may know that its main improvement is that its QAM modulation accuracy is doubled, making the network speed of a single device faster, and the introduction of OFDMA technology can accommodate more device connections; in addition, Wi-Fi 6 also introduces BSS coloring technology, which can reduce signal interference between routers.

At the same time, since the protocol introduces a target wake-up time design, Wi-Fi power consumption can be reduced. Compared with the Wi-Fi 5 routers currently used by most households, the maximum potential speed of Wi-Fi 6 will be 40% higher than the former, greatly improving the data transmission speed.

The most likely protocol to become Wi-Fi 7 is the IEEE 802.11be standard that is currently under development. Compared to Wi-Fi 6 (802.11ax), Wi-Fi 7 is expected to have the following improvements:

1. Wi-Fi 7 will support 16 data streams. Supporting more data streams will also bring more powerful features such as CMU-MIMO.

2. Wi-Fi 7 also introduces a new 6GHz band, and three bands work simultaneously. In addition to the 2.4GHz and 5GHz bands, a new 6GHz band will also be introduced.

3. Wi-Fi 7 upgrades the signal modulation method to 4096QAM to have a larger data capacity. Wireless technology will of course involve the modulation method of the signal. In 802.11ax, the standard uses 1024-QAM modulation, and Wi-Fi 7 is expected to continue to upgrade the modulation method and directly use 4096-QAM to further expand the transmission data capacity and lay a solid foundation for the highest 30Gbps.

With the arrival of Wi-Fi 7, the transmission speed can reach 30Gbps, which will bring users a smoother and faster transmission experience. Because it has a larger coverage area and effectively reduces transmission congestion, it will more effectively promote the popularization of 8K products. In other words, 8K video playback will no longer be a fantasy.
