MVG antenna measurement system is critical to test the wireless connection performance in automotive development and manufacturing.Whether it is to provide consumers with more value-added service experience, or vehicle manufacturers to maintain market competitiveness through technological upgrading, the wireless connection technology in the automotive industry is constantly increasing. The automotive industry will increasingly place emphasis on wireless connectivity to fully realize the potential benefits of this technology.
 

In recent years, actively discussed and developed by the unmanned, it is inseparable from the wireless connection technology. In China, the field of automotive driverless technology or related policies and regulations are constantly advancing. At the just-concluded CES 2018, driverless was a highlight. At the end of last year, "Beijing Guiding Opinions on Accelerating Road Testing of Automated Driving Vehicles (Trial)" and "Beijing Automated Driving Vehicle Road Test Management Regulations (Provisional)" were promulgated to standardize the actual road testing of autonomous driving cars .

For automotive applications and testing of wireless connectivity technology, Aleksis Anterow, head of the 5G project at the French MVG Group, said recently: "For many car manufacturers, wireless connectivity has become a key marketing tactic. The entire ecosystem in the automotive industry is facing enormous challenges To ensure the required wireless connectivity testing and verification capabilities to meet the requirements correctly for reliability, compliance, and consumer experience with wireless connectivity Testing wireless connectivity in a car is absolutely critical, such as test-to-test Safety, the wireless connectivity in a car needs to be optimized, tested and controlled, which involves the entire product life cycle, from the early concept creation phase to production and after-sales service until the end of the vehicle's life, ensuring that even critical systems Works well after years of use. "

One of the most crucial technologies in car wireless connectivity technology is V2X, the car's X connection. "X" can be any object, such as a signpost, other vehicle or pedestrian. MVG offers a complete turnkey automotive test solution SG3000F for the "V2X" test. The SG3000F includes a fast multi-probe test system, an intuitive and easy-to-use Wavestudio software platform, and a fully integrated, powerful Insight data processing toolbox for seamless workflows that enable users to quickly and accurately perform any protocol with high accuracy Test. Wavestudio software platform is constantly updated to the latest protocols and standards to ensure that users are always able to test the content they need. The use of data processing software Insight for three-dimensional sphere characterization ensures that all use cases are tested for true research and development benefits; and high-precision testing with the flexibility to simulate a wide range of real-world materials.

Aleksis Anterow noted that one of the major trends in the automotive industry at the moment is to increase the amount of testing conducted in controlled lab environments. This will reduce test cycle time and improve test case repeatability as compared to testing on the real road. MVG's solution is to simulate key real-life scenarios in a test lab.

To this end, MVG has developed Insight software specifically to enable users to gain additional benefits beyond basic test data. For example: Depending on where the antenna radiator is located, the tester can shift the test area inside the anechoic chamber from the physical center of rotation of the vehicle to the front or rear of the car and improve the accuracy of the test results at higher frequencies. Even though the measurements around the vehicle are truncated (complete sphere is not measured), Insight can calculate very accurate radiation patterns. Insight can also be used to efficiently analyze potential antenna layout locations, shorten design cycles, and reduce the need for costly prototype vehicle research and development in test labs. In addition, with Insight's ability to characterize the vehicle's wireless performance on any floor material, MVG offers a solution that covers the ground with absorbing material and processes data through Insight to efficiently and flexibly simulate the vehicle's ability to operate under various road conditions such as dry asphalt, water or ice-covered bitumen or other materials).

Overall, MVG's automotive OTA solutions have three advantages: one is a fast 3D wireless OTA measurement system and the second is the Wavestudio software platform for intuitive operation of the test range and support for all wireless Protocol, with future scalability, and the third is that Insight's data-processing software enables efficient product design optimization.

V2X technology is equivalent to the third eye installed on vehicles, the industry is working to develop a variety of enterprise V2X solutions. At CES 2018, several world-renowned manufacturers released V2X related results and plans. In China, the NDRC released the draft of "Innovative Development Strategy for Intelligent Vehicles", and formulated the goals of LTE-V2X and 5G-V2X network construction. The development of smart cars and communications technology as a dual engine for V2X applications is foreseeable that as V2X technology is put into practical use, the test of automotive wireless connectivity will become crucial.
