Anonymous users2024-02-05China's telecom 4G frequency band is not exactly the same as the U.S. telecom 4G frequency band.
In China, the 4G network standard of China Telecom is TD-LTE, and its main frequency band is BAND. The U.S. telecom 4G network standard is mainly FDD-LTE, and the frequency band is Band 4.
Therefore, although they are both 4G networks, the 4G frequency bands of telecommunications are different in China and the United States.

Anonymous users2024-02-03China Telecom's 4G network uses a hybrid network of FDD-LTE and TD-LTE, and FDD-LTE is the network standard used by most countries in the world.
4G is a combination of 3G and WLAN, and can quickly transmit data, high quality, audio, ** and images. 4G is capable of speeds of more than 100Mbps**, which is 25 times faster than today's home broadband ADSL (4 megabytes) and can meet the requirements of almost all users for wireless services. In addition, 4G can be deployed in places that are not covered by DSL and cable modems before being extended to entire regions.
Obviously, 4G has incomparable advantages.
