What comes after 5G communications?

This topic seems a bit paradoxical. First of all, it is a math problem. After 5G, there is of course 6G, no need to elaborate. Secondly, what is 5G? Why do we have to follow the commercial definition? What is the real different communication era? Of course, the era dispute is not the main focus of this article, but I hope people can understand the nature of communication and then make good use of communication technology to solve different communication barriers. Therefore, what we need to understand is what level the so-called 5G communication can reach, and will we need 6G to solve new problems in the future?

Strictly speaking, the current mobile communication is still in the second generation (2G) stage, and 3G, 4G, and 5G are only to enhance its depth or breadth. However, we do not need to be unconventional to oppose the different techniques or marketing methods of 3G, 4G, etc. for upgrading technology and services. As we all know, the first generation of mobile communication is an analog mobile phone system, and the second generation is a completely different realm of digital mobile communication, which is the so-called GSM (Global System for Mobile Communications). Therefore, whether it is 3G, 4G or 5G, it is still digital mobile communication, and it does not deviate from the basic definition of global cross-domain communication.

Will there be a third generation of communication that will enter a completely different realm in the future? Will it be after the so-called 5G communication? From a technical point of view, there is only one possibility, that is, entering a space of different dimensions, or communication capabilities beyond the earth. To be honest, humans already have enough problems, why do we need to enter a space of different dimensions? Or is it necessary to contact aliens? Therefore, the recently deceased physicist Hawking warned that we must not try to contact aliens, otherwise it will bring unnecessary disasters to the earth. This should also be a heartfelt statement. Think about it, do people need to call the King of Hell to ask about life and death? What do they need to communicate with ghosts and monsters? Or is it useful to ask the God of Land for a clear card?

The essence of the development of communication is to be able to communicate with each other. Normally, you and I are independent individuals, and it is through communication that we can achieve group operations. Short-distance communication can be achieved through face-to-face communication, while long-distance communication requires the use of various communication technologies. Therefore, eliminating communication barriers is the goal of current communication technology. As the information to be processed becomes more and more diverse and large, the development of technology must keep pace with the times.

But if we analyze carefully, human beings have such complex communication needs, which can be divided into the following three types: first, communication between people; second, communication between people and things or between things; third, communication between people and their own body and mind.

From this perspective, the 5G communication standard can be said to have entered another new realm, that is, from communication between people to communication between people and things or between things. The ultimate goal of GSM mobile communication should be to allow people to communicate freely on the earth without obstacles and dead ends. As for the communication between people and things, another set of technical standards needs to be formulated to achieve it. 5G communication may have such a mission of the times. Why only emphasize the communication between people and things? The main reason is that 5G chips are still based on mobile devices, allowing people to communicate with things, and there is no need to use huge 5G baseband chips between things.

However, there is still a long way to go for communication between people and things. Not only do we have to deal with all things in nature, but we also have to deal with the endless stream of new man-made things. Therefore, it may be too early to talk about the new realm of communication after 5G. In addition, the communication barriers and contradictions between people and their own body and mind mentioned above are more numerous and greater, which is also the key reason why humans still cannot solve the problem under the current advanced transportation and communication. In fact, after 5G communication, it is not necessarily necessary to use external mobile devices. Wouldn’t it be more comfortable and more flexible to embed them directly in the human body? Perhaps in the future, communication operators will no longer add the names of 6G and 7G without hesitation, but call them "Psychic Girl 1.0" or "Psychic Boy 2.0". Smile.
