1G, 3G, 5G, the development in China is not good, it will soon be iterative; 2G, 4G, is very mature in China, and 4G is still the main force. It can be seen that mobile communication cannot be counted in an orderly manner, which is the singular curse of mobile communication.
I really didn't expect that the more high-tech it was, the more superstitious it would be.
In order to clear this layer of fog, we still look back at the history of mobile communication and let the facts tell us the truth.
1G era
In a pre-World War II movie, a pedestrian moves much like a phone call, but this is just an illusion.
The world's first mobile phone was born in 1973 Motorola Laboratories, this first generation of analog standard mobile phone (1G) can only make voice calls, because the shape is bulky, generally more than 1 pound, really need to be carried by hand, so it is called a mobile phone; And because it is often used by the rich and the big stars, it is also called big brother.
The big brother who often appears in Hong Kong movies, the big brother speaks, the voice is very loud, asking people to come, asking for money to come to money.
It was not until the 1980s that Big Brother began large-scale commercial use in developed countries in Europe and the United States, and the number of users in the United States once reached 2 million.
Fourteen years later, in 1987, Big Brother entered the Guangdong region of China. According to Xu Feng, the first user in China to own a mobile phone, he recalled:
"November 21, 1987 was a day I will never forget. On this day, I became the first mobile phone user in China. Although it cost 20,000 yuan to buy a simulated mobile phone and 6,000 yuan to access the network, the mobile phone solved my urgent need for trade negotiations and helped me become the first beneficiary of the market economy. "
Because the scale is extremely limited, 1G has really not developed in China. This is called 1G blank.
The 2G era
The focus of 2G development shifted from the United States to Europe. In 1991, Ericsson and Nokia built the first Global Mobile Communication System (GSM Network) in Finland, marking the official arrival of the second generation of mobile communication technology, the 2G era.
Since 1994, China Unicom and China Mobile have started 2G commercialization, eventually building the world's two largest GSM networks. 2G communication adds the ability to receive data, such as receiving emails or web pages, and the mobile Internet is an inspiration. Although some countries have shut down this ancient network, 2G is still the longest-lived network and is still in large-scale use. This is 2G follow.
The 3G era

In 1999, the Finnish government issued four telecommunications companies with operating licenses for the construction of 3G in Finland, becoming the first country in the world to issue a license to mobile for the future. In 2000, the International Telecommunication Union announced the third generation of mobile communication standards, TD-SCDMA submitted by China officially became an international standard, and WCDMA in Europe and CDMA2000 in the United States became one of the three most mainstream technologies in the 3G era. In 2009, China began to release numbers on a large scale in 3G.
Due to the full development of 2G in the early stage, 3G started late in the mainland and has a strong transition nature. But China has come up with its own standards, so it's called a 3G breakthrough.
4G era
In December 2013, the Ministry of Industry and Information Technology issued TD-LTE 4G licenses to China Mobile, China Telecom and China Unicom, and China began to enter the 4G era. To this day, 4G is still the main force in the mobile communication market. This is 4G synchronization.
The 5G era
As early as 2013, the relevant state departments set up a 5G working group to promote 5G international standards. In 2016, 5G technology research and development experiments were conducted. In 2019, in sync with the United States and South Korea and other countries, the Ministry of Industry and Information Technology officially issued 5G commercial licenses to China Telecom, China Mobile, China Unicom, and China Radio and Television, and China officially entered the first year of 5G commercialization. So far, China has built and put into use 1.7 million 5G base stations, with more than 400 million 5G end users, accounting for more than 2/3 of the world. This is 5G leading.
China has experienced the development of 1G blank, 2G follow-up, 3G breakthrough, 4G synchronization, and 5G-led mobile communications industry. In the follow-up stage, following the previous generation of communication technology, the next generation will inevitably be delayed. In the case of a basic gap in 1G, the mainland has vigorously followed the development of 2G networks (GSM and CDMA), making it the main network from the mid-1990s to around 2010. After the 3G standard came out, the mainland focused on making breakthroughs and proposed its own technical standard TD-SCDMA, which developed in parallel with CDMA2000 and WCDMA, so the transition of 3G networks is also relatively strong. When the 4G network (TD-LTE) came out, it quickly became popular, with speeds faster than 3G's 2M speeds, and mobile phones were cheaper. Why? Because this is China's own standard, mobile phones are sold not only including the cost of hardware sales, but also the cost of technology patents.
If there is a generation of communication technology that is commercially available late and the application time is not long, it will leave the public with a strong and unsuccessful impression of transition. In the early stage of 5G development, there are high costs, higher power consumption, radiation ratio of 4G, etc., and there has been no "killer" application in the past 3 years, which seems to make people feel that the technology is immature and inevitably a transition. But this is not a problem, but will continue to improve, until these problems are solved, 6G will not suddenly jump out like Sun Monkey, disrupting the industrial layout of 5G. The real problem is that the development of 5G faces many legal and ethical issues. For example, 5G autonomous driving will break through the legal provisions that must be someone after the steering wheel of the car, and many regions in China have now delineated the pilot scope of autonomous driving. The application of 5G robots will also break the existing operating framework of human society. Hasn't the basic 5G live video application also changed many industries?
Let's wait and see the latest adoption of 5G!
