TOYO provides wireless communication performance evaluation system to test center

Anechoic chamber at SMVIC

Hybrid test facility capable of testing EMC performance and quality of wireless communications

When used with certain test equipment, the system can be extended to use a patented Radiated Two-Stage (RTS) method approved by the Third Generation Partnership Project (3GPP) for Vehicles.

FREMONT, CALIFORNIA, USA, Oct. 5, 2022 / — TOYO Corporation announces that its Chinese subsidiary, TOYO China, has completed the installation of a “Wireless Communication Performance Evaluation System for Connected Vehicles” and received approval from Shanghai Motor Vehicle Inspection Certification & Tech Innovation Center Co., Ltd. (SMVIC) in August 2022.

Self-driving cars and connected cars cannot exist without high-quality wireless communication. As wireless communication performance is directly related to vehicle safety, it is even more important to ensure high performance for these types of vehicles compared to conventional vehicles.

SMVIC provides automotive manufacturers with testing and certification services that enable them to sell their vehicles in the Chinese market. The organization has been approved to be the first test center for connected vehicles. SMVIC will advance its research on the test method for connected vehicles with the system that we have just delivered.

The “Wireless Communication Performance Evaluation System for Connected Vehicles” is designed and developed by General Test Systems (GTS), a leading company in the field of mobile terminals, antennas and OTA testing. The system is capable of measuring three-dimensional antenna radiation patterns to better understand the characteristics of on-board antennas and to assess the communication quality of 2G-5G SISO, V2X, GPS and BeiDou. When used with certain test equipment, the system can be extended to use a patented Radiated Two-Stage (RTS) method approved by the Third Generation Partnership Project (3GPP) for Vehicles and originally used as test method for LTE mobile terminals and base stations. . This will enable benchmark testing of MIMO communication, a core technology for connected cars.

The system is unique. It converts an existing anechoic chamber into a hybrid test facility for EMC testing and wireless communication performance testing, two essentials for connected cars. The entire system has been redesigned to accommodate a newly added robot arm on a moving vehicle. The test starts automatically once the robot arm is guided to the position designated by the 2D code on the ground. The arm retracts when the test is complete.

We help our customers reduce cost and improve utilization by providing the optimal way to repurpose existing anechoic chambers through a solution like this system or through technical consultation. Leveraging its extensive EMC business experience, TOYO Corporation continues to expand its business footprint not only in China, but also in the United States and other overseas markets.

Main characteristics
・ Hybrid test facility – a large anechoic chamber serves two essential tests for connected cars – EMC performance and wireless communication testing
・ A robot arm on a moving vehicle can automatically adjust an antenna to a designated position
・ Supports multiple test needs, such as radiation performance, reception sensitivity, electromagnetic interference, multi-antenna performance evaluation, and vehicle communication performance evaluation in natural environments
・ System upgradable with 3GPP approved two-stage radiated method

Founded in 2003, Shanghai Motor Vehicle Testing and Certification Technology Research Center Co., Ltd. (SMVIC) is a national automobile testing center accredited by the Certification and Accreditation Administration of the People’s Republic of China (CNCA) and carries out quality inspection of conventional vehicles and new energy vehicles. SMVIC is also accredited by the China National Conformity Assessment Accreditation Service (CNAS), which verifies and confirms that testing laboratories meet the requirements set by ISO/IEC.

Having been approved to be the first national test center for connected vehicles, SMVIC meets the testing and research needs of connected vehicle communication performance, function verification, scene simulation, operation of demonstration and provides technical support in future technology research and application development. SMVIC is also to establish an information security laboratory in cooperation with the National Network Information Office to build a system to test and evaluate vehicle information security.
