How much do you know about the 3G, 4G and 2G network era?

1. Recently, many people say that the operator’s unlimited packages will limit the network standard. Usually the operator will write that it is limited to the 3G network speed. These people mistakenly think that the operator will not allow them to use the 4G network after limiting the speed. , only let them use 3G network, this is a wrong understanding.

2. The operator will not restrict your use of 4G, nor will it limit the network format, but will only limit the network speed. The reason why the operator says it is limited to 3G network speed is because many people do not understand what 3.1Mbps is. How fast is it? The theoretical speed of China Telecom's 3G network is 3.1Mbps. Many people only know that the 4G network is very fast, the 3G network is average, and the 2G network is very slow. The operator only limits the speed to the 3G network to facilitate users' understanding.

3. You cannot believe everything the customer service says. Many customer service staff are half-baked and do not understand the technology. They only follow what is written and do not understand it themselves. Operators are eager for you to use 4G and will not restrict network standards.

4. Taking a step back, restricting network standards is an extremely serious problem. 234G is a universal service, and users cannot be restricted to which standard they can use. 4G service functions and VoLTE are bundled. , once you are not allowed to use 4G, you will also not be allowed to use VoLTE. That is, if you activate VoLTE and the operator shuts down your 4G service function without authorization, it will shut down VoLTE together. This will never happen.

5. The above is for ordinary speed limit packages.

6. So will the operator limit the network standard? The answer is yes, but it will only appear on some extremely special packages. For example, the famous China Mobile WAP20 unlimited package is artificially Forcibly restricting the use of the 4G network. Another example is the time card launched by Guangdong Telecom in the 3G era for 1 yuan for 5 hours, which was also artificially restricted from using the 4G network. Another example is the 3G E-Travel package launched by China Mobile in the 3G era for 20 yuan for 500M. The use of 4G network is artificially restricted. China Unicom also has similar special packages that are artificially restricted from using 4G network.

7. Finally, the lower limit of 3G network speed for 4G network and the limitation of 3G network (only 3G can be used) are two different concepts. The 4G network has lower latency and higher uplink. Even if the speed is limited to the 3G network rate, you can still get a better user experience, but the experience when limited to the 3G network is much worse.

8. Many people’s understanding of network speed is still limited to the download rate. In fact, there are three major network speeds: downlink, uplink, and delay. Among them, the downlink is the most important. Ordinary users rely more on the downlink, but the uplink is actually also very important, and the delay is also very important. If the uplink is poor, WeChat will not be able to send pictures, and if the delay is high, the game party will scold you.

9. Veterans may also consider public IP and private IP. Newbies generally don’t understand this, so it doesn’t matter.

10. This article is just a brief introduction for novices. It is very superficial. Don’t laugh at it for veterans, thank you.

11. I lament that our country is developing rapidly and changing with each passing day. There are many new concepts and a lot of new knowledge. We are lucky to live in this era and enjoy the convenience brought by various technologies. At the same time, we are also unfortunate. Enjoy While it is convenient, it also requires a lot of effort on our part.

12. If you don’t advance, you will retreat. If you don’t learn, you will soon be eliminated by the times. The pressure of life comes from this. People in Beijing, Shanghai, Guangzhou and Shenzhen know the hardships deeply. Sometimes I hope that the times can slow down the pace of development. Wait for us, but this is impossible. The development of the times does not depend on human will. No one can stop the great rejuvenation of our country and our nation.
