July 17, 2025 - "Technical Requirements for the 43 GHz Band Railway Radio Communications System" (hereinafter referred to as the "43 GHz Railway Technical Requirements"), which form part of the "Technical Requirements for the Upgrading of Commercial Land Radiocommunications Systems" (hereinafter referred to as the "Upgrading Technical Requirements") -
- Partial Report from the Information and Communications Council -

　Today, the Ministry of Internal Affairs and Communications (MIC) received a partial report from the Information and Communications Council, chaired by ENDO Nobuhiro, special advisor to NEC Corporation, on the 43 GHz Railway Technical Requirements, which form part of the Upgrading Technical Requirements (Consultation No. 2033, dated May 17, 2013).

1. Background

　In the railway industry, the introduction of one-person train operation is currently under consideration. To ensure proper safety checks during boarding, alighting, and departure, there is growing demand for platform image transmission systems, which transmit video from monitoring cameras installed at multiple locations on the platform to the driver’s cab. To ensure train safety, there is also demand for introducing a high-capacity wireless communication system that enables the station and onboard train sides to exchange onboard videos as well as measurement information from station and train equipment. To meet these demands, radio systems using frequencies in the 43 GHz band have begun to be used.
　The installation of such radio systems is expected to expand significantly in the future, which may lead to increased interference between them. In light of the current situation, the Information and Communications Council has been reviewing these technical requirements. Today, the MIC received a partial report from the Council on the technical requirements for 43GHz-band wireless communication systems for railroads.

2. Future plans

　Based on this partial report, the MIC plans to develop the relevant regulations.
