The United States no longer has 2G/3G, while China has 2/3/4/5G quad networks in parallel

Release:
On January 1, 2023, US telecom operator Verizon announced that its 3G network was officially shut down.
So far, the three largest operators in the United States, AT&T, Verizon, and T-Mobile, have closed their 2G/3G networks, while some small operators have also carried out 2G/3G withdrawal nationwide. Everyone is only focused on the construction and operation of 4G and 5G.
Why do these operators have to shut down their 2G/3G networks? There are several reasons:
1.At present, 2G and 3G networks occupy 900-1800MHz of high-quality spectrum resources. If this part of the resources is released for 4G and 5G, it can provide users with more advantageous services, so operators want to release them.
2.2G, 3G users are getting fewer and fewer, everyone began to migrate to 4G, 5G, and 2G/3G parallel, resulting in rising operating costs, everyone shuts down 2G and 3G networks, can save a lot of manpower and material resources.
So it's not just the U.S., according to GSA, 142 operators in 56 countries around the world have completed, planned or are shutting down 2G/3G networks.
In China, although the three major operators are also planning to retire 2G/3G networks in an orderly manner, they have not really completed the withdrawal, and the three major operators are currently 2G/3G/4G/5G quad networks in parallel.
As for why, the biggest problem is not mobile phone users, but IoT users. At present, the vast majority of mobile phone users have migrated to 4G/5G, and there are quite few mobile phones that only support 2G/3G, which can be basically ignored, so mobile phone user migration is not a problem.
However, due to the long history of the development of domestic 2G and 3G networks, there is currently a huge infrastructure to use 2G/3G networks.
For example, gas meters, water meters, metering meters, etc., all use 2G/3G networks, and the service life of these meters is very long, even up to 10 years, more than 20 years.
These meters, currently using 2G/3G networks, are difficult to migrate to 4G/5G, because users do not have the need to change meters, and they cannot force users to directly change meters, resulting in operators' 2G/3G withdrawal progress is not particularly smooth. But it is undeniable that in order to rationalize the use of spectrum, but also to save resources, but also to better develop 5G and 6G, 7G, etc., network technologies such as 2G, 3G, 4G will be developed step by step as before, and will be cleared step by step, no one can stop it, it's just a matter of time.
