Just used Wi-Fi 6, Wi-Fi 7 of the Big Three is already on the way

The latest generation of Wi-Fi technology Wi-Fi 6 has just begun to spread, and the next generation of Wi-Fi technology has begun to be developed, and the speed is expected to increase by 3 times.

Qualcomm Snapdragon 865 is one of the first mobile phone SoCs to support Wi-Fi 6. So with the launch of Snapdragon 865 and other mobile phones that support Wi-Fi 6, this new connection technology has begun to spread rapidly. At the same time, there are more and more wireless routers supporting Wi-Fi 6.

Now, we are waiting for the next generation of Wi-Fi technology, which should be called Wi-Fi 7. It is understood that the three major chip giants-Qualcomm, Broadcom and MediaTek are already developing related technologies, but this latest Wi-Fi technology will not be used soon. Qualcomm predicts that the introduction of this technology will take at least 2-3 years.

Recently, Qualcomm Vice President Rahul Patel pointed out that Qualcomm has launched and mass-produced a number of Wi-Fi 6 products in the past two years, which are widely used in smartphones, PCs and routers. Wi-Fi 6E products also began mass production in the second half of last year. Qualcomm has already begun the research and development of Wi-Fi 7.

Qualcomm predicts that compared with Wi-Fi 6, the network speed of Wi-Fi 7 will be doubled.

In addition, Wi-Fi 7 can also combine multiple spectrums, which will mean providing higher quality network connections. But again, this technology will not be widely used anytime soon.

In addition to Qualcomm, chip companies such as Broadcom and MediaTek are also actively developing Wi-Fi 7 chips. In this year’s shareholder report, chip manufacturers stated that they have begun to actively invest in the next generation of Wi-Fi 7, and the battlefield extends from smartphones and PCs to more areas. For the entire mobile communications industry, this is undoubtedly a healthy competition.

By the way, Wi-Fi 7 is likely to become the commercial name of the future 802.11be standard. Compared with the maximum 8 data streams of Wi-Fi 6, Wi-Fi 7 will support 16 data streams and CMU-MIMO technology. Among them, C stands for Coordinated, which means that the 16 data streams may not be provided by one access point, but by multiple access points at the same time.

Secondly, Wi-Fi 7 will continue to support the 6GHz frequency band, and the three frequency bands can be connected to work at the same time, expanding the width of a single channel from Wi-Fi 6's 160MHz to 320MHz.

Wi-Fi 7 will also upgrade the signal modulation method to 4096QAM to have a larger data capacity. Therefore, the final speed of Wi-Fi 7 can reach 30Gbps, which is three times the fastest Wi-Fi 6 speed currently launched at 9.6Gbps.
