Sony and Mitsui are collaborating on a system feasibility testing project for the deployment of local 5G networks using Dynamic Spectrum Access (DSA) technology on urban expressways in Japan.
According to the companies, this project is the world’s first attempt to apply Dynamic Spectrum Access (DSA) technology for local 5G networks to achieve automated coordination of wireless spectrum to avoid harmful radio interference issues. As a result, it is anticipated that this initiative will play a significant role in fostering collaborative utilization of local 5G networks in Japan.
The project aims to address the challenges of network coordination and limited spectrum availability in local 5G deployment. The testing will simulate coexisting local 5G networks on urban expressways to automate spectrum allocation and prevent harmful radio interference.
The research will identify technical issues, verify the system’s practicality, and enable more efficient utilization of limited spectrum resources. Sony and Mitsui will leverage the knowledge gained to expand the commercial use of DSA technology and collaborate with partners to promote local/private 5G networks.
In January of this year, Japanese telecommunications operator KDDI also collaborated with Samsung Electronics and Fujitsu, to deploy O-RAN-compliant 5G Open Virtual Radio Access Network (Open vRAN) sites in Osaka, Japan. Its purpose is to meet the growing demand for faster deployment and cost-effective network technologies that can handle the expected surge in traffic resulting from the widespread adoption of 5G services.
