Innovative 5G vehicle OTA test solution

16-11-2023 | Anritsu | Passives

RanLOS, TOYO Corporation, AeroGT Labs, and Anritsu have announced the availability of the first 5G antenna OTA measurement system engineered with RanLOS' OTA test solution and Anritsu's 5G Radio Communication Test Station MT8000A. The new system represents a notable step forward in facilitating advancements in 5G connected vehicles.

As autonomous driving gains momentum and the need for connected vehicles surges, adopting 5G for automotive usage comes with performance necessities for successful implementation. To allow the seamless flow of dynamic, real-time data communication, highly reliable antenna performance is necessary to ensure the safety of autonomous and connected vehicles and to allow advanced infotainment. This need is addressed by optimising and validating antenna design and installation on a vehicle. However, design engineers need a consistent, reliable, and controllable test environment that can emulate real-world conditions to accomplish this critical task.

RanLOS and Anritsu collaborated to fulfil this need by incorporating 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 running on a dynamometer. It is ideal for assessing the performance of antennas on transportation vehicles such as automobiles, vans, minibuses, and autonomous transport systems. What sets the solution apart is its distinctive ability to be seamlessly incorporated into pre-existing EMC chambers, allowing manufacturers to establish an essential testing environment while keeping the initial investment to a minimum.

As measurement solution providers, TOYO and AeroGT Labs, a TOYO-affiliated company specialising in OTA measurements, view this solution as an optimal choice for customers needing a 5G OTA measurement solution for advancing next-generation mobility. Drawing from their wide EMC and antenna measurement business experiences, the companies lead the go-to-market efforts.

"It's a major step to have 5G capabilities integrated into our offering", comments Louice Rosdahl, CEO of RanLOS. "5G is 100 times faster than 4G at peak speed and will be an enabler for safer connected cars. We are grateful for the collaboration with Anritsu and look forward to delivering the benefits of this new offering to our users and customers."

"While the 5G wireless communication quality evaluation is indispensable for the development of the 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 minimise initial investment," said Yoshimichi Imaizumi, director, senior VP 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."

"As transportation vehicles advance further toward an all-interconnected future, holistically evaluating and gauging 5G antenna performance in connected vehicles becomes more than a benchmarking and testing effort," said Steve Wong, chief marketing officer at AeroGT Labs. "This critical process lays the foundation for a transportation future characterised by elevated safety and enhanced efficiency."

"This leading technology is the result of our partnership with RanLOS," said Takeshi Shima, director, senior vice president, Test and Measurement Company President at Anritsu. "By integrating the Anritsu MT8000A 5G network simulator with the RanLOS system, we offer the automobile test marketplace an advanced solution with technologically and cost-effective benefits. With the constant and rapid progress in autonomous services, in-vehicle antenna performance significantly matters. The solution ultimately equates to an improved user experience, which benefits the evolution of widely spreading smart society. We are thrilled to promote it globally, collaborating with TOYO and AeroGT Labs."
