China’s Ministry of Industry and Information Technology (MIIT) and National Radio and TV Administration (NRTA) have jointly announced a plan for establishing a mandatory national standard for an `On-Board radio broadcast receiving system`.
The mandatory implementation of such a system aims to safeguard personal safety, protect lives and property, ensure national security, and meet the basic needs of economic and social management.
This is the further step to the document issued by the three government ministries, MIIT, NRTA and SAMR (State Administration for Market Regulation), in September 2023, actively guiding the Chinese automotive industry to support DRM in AM band (and CDR for FM band) and encourage province transmission stations to broadcast domestic DRM services.
DRM’s Emergency Warning Functionality combines a set of core functionalities to inform the general public (and relevant authorities), as quickly as possible and with maximum coverage, about an impending disaster, giving all relevant information. In case of an active alarm, DRM receivers will switch to the alarm programme automatically and display detailed information in multiple languages simultaneously through DRM’s Journaline advanced text service. Receivers, in standby mode, will wake up automatically.
DRM’s advantages outweigh those of local analogue FM (only covering areas of kilometres), hyper local mobile networks, prone to immediate damage during natural emergencies. DRM’s robustness against local damage due to its large coverage areas is well proven.
This project for formulating a mandatory national standard for `On-Board radio broadcast receiving system` will last for 22 months. This standard applies to in-vehicle wireless radio reception system and the project will mainly cover the technical aspects of the testing and evaluation framework. Specifically, this includes the functional and performance requirements of terminals and antennas. environmental reliability according to automotive regulations, electromagnetic compatibility, as well as the appropriate testing methods.
Currently the project is in the period of public call for project ideas in preparation for the establishment of the project which will run until Oct 2025.
