Shulou(Shulou.com)06/02 Report--

Miao Wei, minister of industry and information technology, said at a press conference of the State Information Office that he had not yet used a 5G mobile phone, but was still using a 4G mobile phone. He said that for the majority of users, 4G mobile phones are enough.

In March 2010, when the 3G era first arrived, the then Minister of Industry and Information Technology also said that he was still using 2G mobile phones and had not upgraded to 3G. He also explained that usually using a mobile phone is to make a phone call, and there is no more energy to do other functions and uses. And said, "because this phone is still easy to use, I don't want to replace it." However, he expressed the hope that the broad masses of consumers will be familiar with 3G and will use 3G to make their lives more colorful.

The views expressed by the two ministers before and after the Ministry of Industry and Information Technology towards the new communication era are indeed a bit similar, but they are not exactly the same. This also shows once again that young talents are the main force in the information age. Even industry leaders have not yet felt the experience of communications upgrade.

But this is only a temporary phenomenon. After retiring, Li Yizhong visited the people's Daily Power Forum and said that there is plenty of time now. He already has 3G mobile phones and can surf the Internet every day.

Will 5G phones change back to 4G? It's possible

This time, the minister of industry and information technology did not cause much controversy in his speech whether he used a 5G mobile phone, but another sentence sparked a great debate inside and outside the industry.

Miao Wei said that most of the 5G phones commercially released in the Chinese market are not independently networked. To really reflect the performance of 5G, we have to rely on the independent network of 5G network, rather than the NSA based on 4G core network, that is, non-independent network of 5G products. Huawei is now the only phone that is compatible with NSA and SA.

With regard to the construction of 5G, Miao Wei said that it will be put into an independent 5G network on a large scale next year. Miao Wei said that 80% of the real application scenarios should be used in the communication between things, such as industrial Internet, car networking, telemedicine and other fields.

The problem is clear: the Ministry of Industry and Information Technology is promoting the construction of independent networking (SA) 5G, and the current NSA is only in a transitional state, and the time is next year.

Previously, China Mobile has said that by next year, only phones with independent networking functions will not be able to access the network. China Telecom has also made it clear that it will build an independent network as the goal of building a network. China Telecom and China Unicom have announced that they will jointly build a shared 5G network, which means that China Unicom will also form a separate network.

We can draw the following conclusions:

Whether it is NSA or SA, it is true 5G, the dispute over true and false 5G can be stopped, but true 5G is not the same degree. If the 5G of SA is 100 degrees, then NSA is 30 degrees and the water is just warm.

Although operators will build a certain number of NSA networks in 2019, this is a transitional state, and SA will mainly be built in 2020.

In the future, not all 5G base stations will support NSA, that is to say, 5G mobile phones that only support NSA will probably not be able to use the base stations built by operators after 2020.

The current 5G mobile phones that can only support the NSA network will not all be able to access the 5G network in the future 5G network, but will fall back to the 4G network when they can only support SA.

All phones will support NSA, but not all phones will support SA, users need to make reasonable choices according to their own needs, do not be swayed by some manufacturers.

Don't say that 5G is useless, because these people said the same thing in the 3G and 4G era.

SA is the trend of the times, as well as internationally, otherwise, 5G really doesn't make much sense, so don't believe what some manufacturers say that SA is unnecessary.
