Japan to Revise Radio Equipment Regulations for 43GHz Band Railway Systems
Japan has announced upcoming changes to its radio equipment regulations, with new
technical standards being introduced for railway communication systems operating
in the 43GHz frequency band.
Key Points of the Amendment
- -Scope: Partial revision of the Regulation for Radio Equipment and
the Ordinance on Technical Regulations Conformity Certification.
- -Purpose: Support one-man train operations through real-time
video monitoring of platforms, while also strengthening safety by enabling secure
data and video transfer between trains and ground systems.
- -Technical Focus: Establishes standards for communication methods,
modulation schemes, antenna power, frequency use, and related specifications
within the 43GHz band.
- -Certification: Designates these systems as specified radio
equipment, requiring conformity assessment to ensure compliance and minimize
interference risks.
Implementation Timeline
The revised regulations are scheduled to take effect in December 2025.
