The Ministry of Industry and Information Technology unexpectedly disclosed the domestic 5G scheduled frequency band: starting from 3300MHz

Huawei's Kirin 970 chip pioneered the 1.2Gbps commercial LTE baseband for the first time, entering the 4.5G era of Pre 5G. According to the plan of international organizations, 5G will be rolled out as early as the Pyeongchang Winter Olympics next year, and the 2020 Tokyo Olympics will show a mature global posture.

However, 5G also requires a dedicated frequency band, that is, radio frequency. The "Radio Frequency Division Regulations (Revised Draft for Comments)" recently drafted and published by the Ministry of Industry and Information Technology has released a new signal for 5G.

The part of the draft opinion concerning the "International Mobile Telecommunications (IMT) system" is as follows:

[[202375]]

Mobile services in the CHN34 3300-3400MHz frequency band are intended for use in the International Mobile Telecommunications (IMT) system and are limited to indoor use in principle.

CHN35 Mobile services in the 4400-4500MHz frequency band can be used for the International Mobile Telecommunications (IMT) system. The IMT system shall not cause harmful interference to the aeronautical radio navigation service in the 4200-4400MHz frequency band, and the IMT system cannot be put into use before the relevant compatible coexistence conditions are determined.

Mobile services in the CHN37 4800-5000MHz frequency band are used for international mobile communications (IMT). The specific frequency allocation and use should take into account the usage needs of relevant departments.

The author believes that 3300-3400MHz, 4800-5000MHz, and 4400-4500MHz can be understood as being basically determined as dedicated frequency bands for 5G.
