Note: The published materials are in Japanese only.

　Today, the Ministry of Internal Affairs and Communications (MIC) received the partial report from the Information and Communications Council, chaired by ENDO Nobuhiro, Special Advisor to NEC Corporation, on the Extension and Introduction Technical Requirements, which form part of the V-High and Narrowband Communication Systems Technical Requirements (Consultation No. 2046 dated June 6, 2024).

1. Background

　Regarding the use of vacant frequencies following the termination of V-high-band multimedia broadcasting, the Subcommittee on the Study of the Utilization of Broadcasting Frequencies recommended, in June 2022, that the introduction of systems that enhance communication services—including public broadband mobile communication systems and narrowband IoT communication systems—be studied.
　In light of this situation, it is necessary to enable the introduction of V-high-band public broadband mobile communication systems and narrowband IoT communication systems. Accordingly, the Information and Communications Council has been examining the relevant technical requirements and has submitted the partial report on these requirements today.

2. Future plans

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