A first-of-its-kind 5G antenna over-the-air (OTA) measurement system has been launched by RanLOS, Toyo Corporation (Toyo), AeroGT Labs and Anritsu. The system has been engineered with RanLOS’ OTA test solution and Anritsu’s 5G Radio Communication Test Station MT8000A and is designed for seamless integration with existing EMC chambers.

As autonomous driving and the demand for connected vehicles gain momentum, the adoption of 5G for automotive use comes with performance requirements for successful implementation. Highly reliable antenna performance is a key necessity to ensure the safety of autonomous and connected vehicles and to enable advanced infotainment. This requirement is addressed by optimizing and validating antenna design and installation on a vehicle.

RanLOS and Anritsu collaborated to meet this need by integrating a portable antenna test system with a wide dynamic range base station simulation. The combined solution supports the measurement of throughput and antenna radiation patterns under static conditions and the evaluation of throughput degradation in vehicles operating on a dynamometer.

The solution allows the assessment of the performance of antennas on transportation vehicles such as automobiles, vans, minibuses and autonomous transportation systems. What’s more, it can be integrated into pre-existing EMC chambers, giving manufacturers the opportunity to establish an essential testing environment while keeping initial investment to a minimum.

As measurement solution providers, Toyo and AeroGT Labs, a Toyo-affiliated company specializing in OTA measurements, view this solution as an optimal choice for customers requiring a 5G OTA measurement solution for advancing next-generation mobility. Drawing on their broad EMC and antenna measurement business experience, Toyo and AeroGT Labs are leading the go-to-market efforts.

“While the 5G wireless communication quality evaluation is indispensable for the development of next-generation mobility including connected and autonomous vehicles, no standard test method has been established. In this context, the solution created by integrating Anritsu and RanLOS products offers a simple and intelligent way to evaluate the 5G on-vehicle wireless communications and minimize initial investment,” said Yoshimichi Imaizumi, director and senior vice president at Toyo. “By promoting this sophisticated yet cost-effective solution to the mobility industry, we contribute to the building of a safer and more trusted traffic network.”
