Vienna, Austria – 18 September 2025 – is pleased to announce that Sojitz Tech-Innovation Co., Ltd. (STech I) has selected Anritsu’s Handheld Spectrum Analyzer Field Master Pro MS2090A to evaluate the wireless quality of its private 5G platforms, aimed at the Japanese market. The MS2090A has an extensive track record in private 5G verification experiments conducted by the Ministry of Internal Affairs and Communications, earning high marks for its reliability, superior performance, and excellent operability—factors that led to its selection. By leveraging the MS2090A, STech I can now verify compliance with Japan’s Radio Act, manage wireless quality, and quickly troubleshoot issues.

The barriers to introducing private 5G networks are gradually being eliminated by deregulating the sharing of private 5G base stations and simplifying licensing. However, operational complexities persist. To address this, STech I has introduced the private 5G LAN solution from Celona, a U.S.-based leader in enterprise 5G, to the Japanese market. The platform provides all the core functions required for private 5G, simplifying optimization from deployment to operation. A key strength is that organizations can manage the 5G mobile network as easily as Wi-Fi, without needing advanced technical knowledge. Even so, growing the Japanese market required addressing challenges such as compliance with the Radio Act and assuring wireless quality. To meet these needs, STech I selected the MS2090A, recognized for its high reliability and precise evaluation of wireless characteristics.

Anritsu will continue to support the deployment and quality management of private 5G environments, contributing to the widespread adoption of private 5G.
