If 12345G were in a WeChat group, what would they talk about?

Scene 1

The development and rise and fall of mobile communications 12345G

Knowledge points in this section

1

There were many different 1G technologies, and they were different in many countries, but they were all soon replaced by 2G.

Therefore, people don’t need to know too much about 1G technology, so the general term “1G” is directly used.

2

There is only one 5G standard in the world, so there is no need to give it a technical name. Just call it 5G, simple and clear!

Moreover, 2019 is the first year of 5G, and the first wave of deployment is ushered in around the world.

Therefore, 5G said in the group chat that he was "the sun at eight or nine o'clock in the morning."

3

In the 4G era, Qualcomm proposed a 4G technology based on CDMA: UMB.

However, industry leaders were scared by Qualcomm's patent fees, and no one was willing to cooperate, so Qualcomm eventually gave up the technology.

As a result, LTE became the only 4G product. Therefore, UMB said in the group chat that Qualcomm was "too calculating".

4

The last 3G technology: WiMAX, also known as 3.75G, was once very popular, prompting the birth of the 4G standard LTE ahead of schedule due to competition.

With the abandonment of its main supporter Intel, WiMAX suffered a setback and was eventually defeated.

Therefore, LTE said in the group chat that it would "press WiMAX to the ground", and WiMAX responded helplessly that Intel was a "pig teammate".

The three main technologies of 3G: WCDMA, CDMA2000 and TD-SCDMA all inherit the mantle of CDMA technology in the 2G era.

Therefore, CDMA said in the group chat that these three 3G technologies are its bloodline.

The main patent holder of CDMA technology is Qualcomm of the United States.

2

TD-SCDMA in the 3G standard is a technology dominated by China and has been widely used in China Mobile.

However, due to its immature technology and poor user experience, it has been virtually abandoned by China Mobile and is currently being withdrawn from the network.

Therefore, 5G says that TD-SCDMA is "seriously aging prematurely."

1

2G technology is dominated by Europe, America and Japan: Europe's GSM, America's CDMA, Japan's PDC and PHS.

PHS later developed into the famous Xiaolingtong in China, while PDC quietly died out in Japan.

So Xiaolingtong @ed PDC in the group chat. Of course, PDC was not in the mood to chat.

2

2G GSM technology is the most widely used communication system in the world.

Currently, China Mobile and China Unicom's 2G both use GSM technology. Although 3G and 4G are now absolutely mainstream, there are still many 2G users.

China Mobile will withdraw 3G from the network and retain 2G because the 3G TD-SCDMA technology is relatively weak.

Therefore, GSM said in the group chat that 2G's "glorious era has passed, but its territory is still large."

3

In 2009, the Chinese government authorities required the 2G Xiaolingtong service to be shut down to ensure that it would not cause harmful interference to the 3G TD-SCDMA service that was about to be launched.

Therefore, Xiaolingtong said in the group chat that "because it has to make room for 3G TD-SCDMA, it has retired gloriously."

Act II

Talking about the development of mobile services and new applications of 5G

Knowledge points in this section

1

1G technology is only used for making phone calls. The mobile phones are large, heavy and expensive, and are commonly known as "big brothers".

2

2G technology allowed text messaging and Internet access. But the speed was very slow. Most people’s monthly data packages were only a few dozen megabytes, which was enough to read novels and full-text news. However, the door to the new world of the Internet had been opened.

3

In the 4G and 5G era, no one cares about making phone calls anymore. As the most basic communication application, voice services have become as accustomed to us as water and electricity. Various instant messaging tools such as WeChat and QQ have already integrated phone and video functions.

1

When the 3G standard was being formulated, senior experts pondered over what users could do with such a fast Internet speed. So they came up with a requirement: video calls! That is, calls with video.

The final result proved that this was a closed-door project and no one used it at all.

2

3G technology is much faster than 2G. It is effortless to view pictures and videos online. However, data traffic is expensive. Most people have data packages of several hundred megabytes per month, which is far from enough for watching videos.

Therefore, before clicking on a video at that time, there would be a warning: Playing it will use a lot of data and cost a lot of money, are you sure you want to watch it?

Since the 3G era, with the main focus on home WiFi, various mobile phone software have migrated to mobile phones, and the mobile Internet has finally exploded.

Since then, mobile phones have become a part of our bodies and have reshaped the lifestyles of most people.

3

4G and 5G did not support phone calls at the beginning, and they focused on Internet speed. If a user wanted to make a phone call, it was directly handed over to 2G and 3G to solve it.

Of course, after 4G became popular, we could also make phone calls, and the development of 5G is also in the same direction.

Knowledge points in this section

1

Compared with previous generations of technology, 5G has three major characteristics: large bandwidth, high reliability, and low latency.

The industry hopes to combine these special features of 5G to create more valuable applications, such as autonomous driving, telemedicine, industrial control, etc.

2

These industry applications of 5G seem very promising, but there are also many restrictions, and the future is full of variables and imagination.

At present, 5G's killer applications are still in the making, and we are full of expectations.

Conclusion

5G remote surgery was mentioned in the group chat about various technologies. However, the medical industry is a matter of life and death, and has extremely high reliability requirements, and the responsible parties must be clearly divided. Can 5G really achieve this application?
