On June 28, China’s Ministry of Industry and Information Technology (MIIT) released an infographic interpretation of the new version of the Provisions on Radio Spectrum Allocations, which was released on May 23, 2023. The purpose of the revision is to align with the International Telecommunication Union’s Radio Regulations (2020 Version) and meet the domestic requirements for radio-frequency spectrum usage. The revision underwent coordination, verification, opinion solicitation, research, and improvement procedures, with the final draft approved by MIIT on April 26, 2023.
The major revisions in the Provisions include:
- Allocation of new frequency bands for International Mobile Telecommunications (IMT) (including 5G/6G) in the 6GHz, 26GHz, 40GHz, and 70GHz bands. The allocation of new frequency bands for IMT,a leading worldwide move of the 6GHz band, promotes global or regional alignment and supports the development of 5G/6G with sufficient medium frequency resources.
- Establishment of provisions for maritime mobile-satellite service and mobile-satellite service in the frequency bands of 150MHz and 400MHz, respectively. The Provisions introduce Earth Station in Motion (ESIM) application to the frequency bands of 17.7-19.7 GHz and 27.5-29.5 GHz. Additionally, the Provisions clarify the working conditions of non-geostationary satellite orbits (non-GSO) in certain frequency bands between 37.5-51.4 GHz.
- Clarifyinginterference protection for Earth Exploration-Satellite Service (EESS), radio astronomy, and other radio services.
- Radio positioning services in the 79-81GHz band will be prioritized for applications such as automotive radar.
