The next generation of wireless technology - Wi-Fi 7 - how powerful is it?

Ken Mobile will have faster speeds and lower latency.

The current Wi-Fi 6 and even Wi-Fi 5 technology introduces many of the technologies used in mobile networks, also known as 4G 5G, such as beam focussing, a technology that greatly improves the directionality of the signals sent by the router. By interfering with multiple antennas the signal is directed to the terminal, significantly solving the previous problem of omnidirectional antenna coverage distances.

The "main flap" in the middle, created by beam focussing, is highly directional and has a much longer range. 

There is also the introduction of MIMO (Multiple In Multiple Out) technology in Wi-Fi 5, which gives mobile devices a huge increase in data throughput. The latest Wi-Fi protocol is Wi-Fi6e and there are only a handful of routers and terminals that support this protocol. Personally, I think Wi-Fi6e may not catch fire in China because the Ministry of Industry and Information Technology may not approve Wi-Fi6e. The main reason for this is that although Wi-Fi6e provides more frequency bands, which effectively improves device band capacity and transmission speed, it conflicts with some of the frequency bands of the 5G network   currently under construction in China. However, individuals are only limited and perhaps Wi-Fi6e has the ability to solve this problem.


The protocol specification for Wi-Fi7 is presumably still being developed right now, and it will be a long time before the actual launch and the corresponding wireless terminals are launched. However, now our broadband bandwidth Wi-Fi5 is in fact fully satisfied, as long as it is not a special demand Wi-Fi6 and 6e are not particularly necessary now. Except of course if there are special LAN transmission needs or scenarios that require new features.


Personally, I think that Wi-Fi7 will have a higher frequency than the previous generation, which means that it can carry more bandwidth, although the signal coverage capability will definitely be reduced, which can be referred to 5G base stations. The 5G speed is now double that of 4G to a large extent due to the significant increase in communication frequency, which also leads to a decrease in signal coverage and an increasing number of base stations.

Wi-Fi technology has been developed for over twenty years since it came out in the late 1990s and there have been numerous technological enhancements. Now Wi-Fi is not only used for internet access, there are also many transmission technologies based on Wi-Fi featured LAN, such as Apple's AirPlay, airdrop, etc. Huawei's Internet of Everything and collaboration between devices also rely on the huge bandwidth of current Wi-Fi technology.
