What is the difference between 3G and 4G? Can I still call the Internet after 3G withdrawal?

With the advent of 5g era, 3G network will be eliminated soon, but many people have questions about why 3G will withdraw from the network and 4G will not? What is the difference between 3G and 4G? What impact will 3G withdrawal have on our life? Will it affect 3G users to surf the Internet and make calls? Let's talk about the difference between 3G and 4G speeds and the impact of 3G withdrawal. Let's have a look.

Can I still call the Internet after 3G withdrawal?

On March 12, the reporter confirmed from the website of Fuzhou Municipal People's government that a letter published on January 29 displayed on the website said that Fuzhou Radio Administration agreed to China Mobile's application for cancellation of TD-SCDMA Base station.

In fact, China Mobile's gradual retreat from 3G has long been a harbinger. In November last year, China Mobile's 5g terminal strategy released by China Mobile said that in terms of mode and frequency band, 5g terminal products provided by smartphone enterprises need to support five mode 5g NR, 4G TD-LTE, 4G LTE FDD, 3G WCDMA and 2G GSM mode frequency band at the same time. Data terminals support 5g and 4G. It is not required that the first batch of 5g mobile phones need to support 3G TD-SCDMA system.

Earlier, some netizens announced that since IOS 11.3 beta, China Mobile began to shield iPhone from connecting to TD-SCDMA network. After the netizen's test, even if the mobile MiFi 3G signal is full, there is no mobile 4G signal locally, and the 2.75g edge network will be connected by default. The new configuration file allows users to switch between 2G and 4G when using China Mobile.

Insiders told that in fact, the three major operators have been doing 2G and 3G network frequency reduction, but the focus is different. It is reported that China Mobile is reducing the frequency of 3G network (reducing the frequency until all 3G base stations disappear, that is, 3G is out of the network), while China Telecom and China Unicom are reducing the frequency of 2G and 3G networks.

What is the difference between 3G and 4G?

4G is the abbreviation of the fourth generation mobile communication technology, and its network speed can reach more than ten times to dozens of times of 3G network speed. In the ideal state, the peak network speed of mobile 4G network can reach 100MB BPS (generally abbreviated as Mbps, that is, the transmission speed per second is 12.5mb. If you download 700MB movies, it takes 700 / 12.5 = 56 seconds. However, due to the influence of terminal capacity and network configuration, the downlink network speed can generally reach 60-80mbps, so it takes more than 1 minute to download 700MB movies.

Can we still use the Internet to make phone calls when 3G goes out of the network? Won't there be no signal everywhere?

According to the data of the Ministry of industry and information technology, by the end of 2018, the total number of mobile phones in China had reached 1.57 billion, including 1.17 billion 4G users. In other words, there were 400 million 2G and 3G users in China.

Will the withdrawal of 2G and 3G affect these users? Fu Liang, an independent Telecom analyst, believes that the network frequency reduction of the three major operators is a gradual process, and 2G users don't have to worry too much. China Unicom also said earlier that the frequency reduction is not to shut down the network, but a gradual 'slimming' process.

In addition, as mentioned above, the three major operators focus on network frequency reduction. As we all know, China Mobile still has a large number of 2G users, but now it is doing 3G network frequency reduction.

According to the latest data released by China Mobile, as of the end of January, China Mobile had 927 million users, including 717 million 4G users, which means that China Mobile has 210 million 2G and 3G users.

Xiang Ligang, an expert in the communication industry, said that it is normal for the old technology to withdraw. Why does 2G GSM still not withdraw from the network, because the main function of GSM is to make calls. Today, many telephone services still use 2G network, and they can't make calls after returning the phone. 'in the future, a basic pattern will gradually form that 3G and 4G will withdraw from the network, but 2G is difficult to withdraw.'

To sum up, 3G withdrawal will not affect everyone's use of the network and making phone calls. You can use it at ease!
