Japan's Public consultation: 5G development in the 26 GHz and 40 GHz bands

Japan is taking a significant step forward in shaping the future of mobile connectivity by advancing the development and deployment of 5G systems in the critical 26 GHz and 40 GHz frequency bands. These high-frequency bands are essential for addressing the rapid surge in mobile data demand and enabling cutting-edge services that rely on ultra-fast, low-latency communication.

The Next-Generation Mobile Communication Systems Committee, under the Japan Communications Council, is spearheading efforts to define the technical conditions necessary for the efficient and interference-free use of these bands. Their work is instrumental in ensuring optimal spectrum utilization while safeguarding the performance of existing systems operating in adjacent or shared frequencies.

Comprehensive interference studies have been carried out in the 26 GHz band, assessing coexistence scenarios with technologies such as fixed wireless access (FWA), earth exploration satellites, inter-satellite links, and low-power communication systems. Similar analyses for the 40 GHz band have included fixed communication satellites, FWA, and other mobile and public communication systems. These efforts aim to strike a careful balance—fostering 5G innovation while maintaining the integrity and functionality of other critical services.

**WHO DOES THIS AFFECT? **

Therefore, it directly impacts the technology industry, end users, the public and private sectors, and scientific research.

**CONCLUSION: **

The development of 5G in the 26 GHz and 40 GHz bands has a significant impact because it drives technological innovation, improves international competitiveness, and transforms key sectors, positively impacting both industries and end users.
