A world first! Traffic lights are used as 5G base stations: Japan has come up with a wave of cool operations

The small signal coverage range of 5G base stations is one of the problems that need to be faced in the application of 5G technology. According to current reports, its ideal coverage range in densely populated cities is only about 250 meters, which means that the number and density of 5G base stations will increase exponentially compared to 4G.

It is conceivable that when 5G base stations are fully deployed, every corner of our lives will be filled with base stations. Therefore, how to efficiently use existing equipment and not add too much to save resources and costs is an issue that technicians need to consider urgently.

From the perspective of 5G applications, the coverage of 5G base stations is mainly affected by the height of the base stations and the building density. Based on this feature, the Japanese government came up with the idea of ​​​​traffic lights.

According to foreign media reports, the Japanese government plans to use traffic lights as base stations for the next-generation communication standard "5G", and held a meeting of relevant government departments on the 2nd of this month. The Japanese government plans to start actual verification in 2020, and may roll out all of them in Japan as early as 2023.

In addition to its own use, the Japanese government will also establish standard specifications and strive to export them overseas. Some netizens on Weibo suggested that the use of traffic lights as 5G base stations is not the first in Japan, and my country has also proposed such methods. However, we need to realize that this time Japan is applying it in national units, which is indeed the first in the world.

Although Japan is ahead in this regard, we should not be discouraged. Once a method is proposed, it is not as simple as just executing it immediately. Using traffic lights as 5G base stations will face many problems such as maintenance costs, construction costs and signal quality.

In any case, Japan's use of traffic lights as 5G base stations has set a good example for us. In this regard, we also believe that the wisdom of the Chinese people is infinite. We can create much more than just leading in 5G technology.
