China Mobile Research Director: 5G network has been developed

"No matter 3G, 4G or 5G networks, network construction is mainly composed of three main parts: Base Station, transmission network, and core network. The transmission networks and core networks of these generations are basically the same. Only a small number of new construction or modifications are required for base station construction to avoid repeated construction ." Huang Xiaoqing, president of the China Mobile Research Institute, said that although the commercialization of 4G networks has not yet been officially rolled out, China Mobile has already invested in R & D of 5G networks.

Huang Xiaoqing introduced that the first and second generation communication technologies mainly solve the problems of voice calls. The third generation technologies solve some problems related to mobile Internet networks and high-speed data transmission, the 4G network, which represents the four-generation communication technology, is a communication technology designed specifically for the mobile Internet. Therefore, the network speed and stability are greatly improved. "Network construction is different from traditional road construction. The latter is just one year wide. According to the current mobile Internet development speed, people's demand for the quality of communication networks doubles every year, and 10 years later is about 1000 times. Therefore, you must enter the Development of the Next Generation Network in advance ."

Huang Xiaoqing explained the continuous change of 2G, 3G, 4G, and 5G networks, as well as repeated network construction and resource waste, because the 4G network being fully deployed nationwide is almost identical to the original network in the transmission network and core network, only a small number of changes are required on the base station. Therefore, the new generation network has a high utilization rate for the previous generation network, it will avoid repeated construction to the greatest extent possible.
