With the continuous miniaturization of mobile terminal devices such as cell phones and laptop computers, R&D testing of the built-in low-directionality antennas has become critical. The weaknesses associated with large far-field chambers are well-known: large size, slow in test, expensive, and not cost-effective. Learn more.
The OTA testing of 5G cellphones undergoing mass production is facing unprecedented challenges. The number of antennas and frequency bands under test has increased extensively. The higher frequency bands used by 5G make OTA testing even more difficult. All of these challenges lead to a much longer test time, a more complicated procedure for NPI, and a higher cost. TOYO introduces PinProbe M6, an innovative solution that provides almost 6 times higher efficiency with a considerably lower cost.
The automotive industry is undergoing a profound change with Intelligent Connected Vehicles (ICVs) being widely viewed as the future of mobility. With the convergence of vehicle information communication, AI, the internet, and other technologies, the ICV enters a new stage of rapid technology evolution with a variety of communication devices (including wireless transceiver, antenna, and corresponding software).
An intelligent connected vehicle (ICV) is fitted with a myriad of wireless systems (V2X, cellular, Bluetooth, satellite navigation, etc.). To ensure the reliability and integrity of vehicle operation, we must perform full vehicle communication performance testing in a real environment. The two major challenges of the test are how to perform a near field antenna and EIRP/EIS test under the eccentric condition, and how to rebuild a real-world transmission environment in the lab and execute the MIMO performance test.
To Deliver Innovative Wireless Communication Performance Measurement System for Connected Vehicles in a Deal Worth 5 Million USD
Tokyo, Japan, May 12, 2021 – TOYO Corporation announces that its Chinese subsidiary, TOYO China, received an order for a “Wireless Communication Performance Measurement System for Connected Vehicle” from the China Intelligent and Connected Vehicles (CICV) Research Institute in Beijing. The order amount is 5 million USD, with a scheduled delivery targeted for June 2022.
This system applies the Radiated Two-Stage (RTS) method approved under 3GPP as a test method for LTE mobile terminals and base stations to measure the in-vehicle wireless communication performance required for connected vehicles. Since its founding in December 1998, the 3GPP or Third Generation Partnership Project has been a collaboration established to develop protocols and globally agreed specifications for third-generation (3G) mobile systems.
The TOYO Wireless Communication Performance Measurement System can be augmented to support a large-scale Electro Magnetic Compatibility (EMC) anechoic chamber for automobiles. EMC refers to a device that is compatible with its electromagnetic environment and it does not emit levels of EM energy that cause electromagnetic interference in other devices in the vicinity. As a result, the TOYO Wireless Communication Performance Measurement System can support Over-The-Air (OTA) test needs in conjunction with existing EMC testing systems for in-vehicle wireless communication performance evaluation essential for the development of connected vehicles. Over-The-Air testing is a technique used to evaluate performance in a wireless communication environment.
Through a strategic partnership with CICV, a national research institute with advanced technology that leads the ICV (Intelligent Connected Vehicle) industry in China with global influence, TOYO Corporation continues to expand its business footprint not only to China, but also to the United States, and other overseas markets taking advantage of its broad EMC business field experience.
TOYO Corporation supports the development of safer vehicles by providing measurement solutions necessary for the development of advanced driver assistance systems (ADAS) and autonomous driving (AD), for both domestic and overseas markets.
New performance measurement systems required for development of highly reliable connected vehicles
As the level of autonomous driving progresses, the importance of Vehicle to Everything (V2X) to measure the wireless communication performance of vehicles by OTA is increasing to realize highly reliable advanced driver assistance systems (ADAS) and autonomous driving (AD). Vehicle to Everything is a technology that allows vehicles to communicate with moving parts of the traffic system around them or with one another. In China, there is a movement to require these evaluations as certification tests for vehicle sales, and each national laboratory is considering the introduction of a new measurement system that corresponds to these new technologies. In addition, China is promoting the adoption of cellular V2X as the main communication technology used in connected vehicles. As 5G cellular communication technology becomes popular in mobile networks, V2X, which includes 5G as one of its communication modes, is expected to become the mainstream technology of intelligent network vehicles and standard for the autonomous driving market. Conventional OTA measurement systems have limited performance in evaluating automotive vehicle systems and have not been able to meet the measurement requirements for connected car development through wireless communication.
Enabling measurement of in-vehicle wireless communication performance essential for the development of connected vehicles
The “Wireless Communication Performance Measurement System for Connected Vehicles” is a system for measuring the wireless communication performance of automobiles. It was developed by General Test Systems, one of the industry’s leading companies in the field of mobile terminals, antennas, and OTA testing. This system utilizes GTS’ Radiated Two-Stage (RTS) method patented technology and the technology has been approved by the 3GPP as a test method for LTE mobile terminals and base stations for the measurement of in-vehicle wireless communication performance for connected vehicles. Radiation performance, reception sensitivity, electromagnetic interference, multi-antenna performance evaluation, and vehicle communication performance in real-world environments are also available for evaluation.

Compared to relatively low-frequency antennas, mmWave phased array antennas have a narrower beam width and shorter wave lengths, so their sampling resolution would be much higher. Meanwhile, an active phased-array-antenna usually has multiple test ports and multiple beam pointing status (each status represents an antenna pattern in the main lobe direction). It is necessary to test multiple-beam pointing status (beam position). These will dramatically increase the total testing time for a single antenna array. With the conventional test method, an engineer must test every status for each port one by one, and as a result, the test efficiency is quite low. For example, a 10×10 antenna array can be tested in one week.
