On January 2nd, it was learned from the Ministry of Industry and Information Technology that China Mobile has recently been granted permission to re cultivate multiple frequency bands below 3000 MHz that have been used for 2G/3G/4G systems, which can be simultaneously used for 5G public mobile communication systems, increasing the support of radio frequency resources for 5G. The reporter learned that frequency resources below 3000 MHz have the characteristics of low radio wave propagation loss, long signal transmission distance, and low network deployment cost, making them the main frequency band for international public mobile communication. This time, China Mobile is allowed to carry out frequency re cultivation, which is conducive to the improvement of 5G network coverage and communication capacity in rural and remote areas, better meet the communication needs of industrial Internet, Internet of Things, Internet of Vehicles and other industries for high-speed, low latency, and large connectivity applications, and promote the high-quality development of China's 5G industry. At present, the Ministry of Industry and Information Technology has granted public mobile communication radio frequency resource bandwidth of 1109 MHz to four basic telecommunications operators, of which 86.5% can be used for 5G.
