Full-Vehicle 5G MIMO OTA Test System Adopted by CICV

12/11/2021

Introduction

Anritsu Corporation is pleased announce that China Intelligent and Connected Vehicles (Beijing) Research Institute Co., Ltd. (CICV) has adopted an over-the-air (OTA*1) test system in a MIMO*2 environment developed jointly by General Test Systems Inc. (GTS) of Guangdong, China, and Anritsu.

Background

With advances in autonomous driving level*3, development of 5G and V2X as core technologies is accelerating worldwide. The Chinese-government has set policy targets to develop mass-produced smart vehicles by 2025, and vehicles with built-in 5G are now being sold commercially. The number of 5G base-station installations to support this plan reached 1 million in 2021. In addition, Pre-sales vehicle certification tests are increasingly using evaluation of 5G communications technologies, resulting in accelerating deployment of MIMO multi-path test systems.

CICV is a leading Chinese research Institute in advanced ICV*4 technology and is promoting development of test standards for implementing high-reliability ADAS*5 and self-driving vehicles.

Test System Details

This system was developed by combining the OTA test system from GTS, a world-leading specialist company in mobile-device, antenna, and OTA testing, with Anritsu's Radio Communication Test Station MT8000A and Radio Communication Analyzer MT8821C. The high-dynamic-range RF performance of the MT8000A and MT8821C enables successful 3GPP-specified Radiated Two-Stage (RTS*6) testing in a MIMO environment, which is essential to evaluating radiated emissions performance, receiver sensitivity, receiver EMI, multi-antenna performance, and communications quality in actual usage environments.

Anritsu's General Manager of IoT Test Solutions, Mr.Yukiharu Ogawa, said, "This leading technology is the result of our long-term partnership with GTS to improve the safety and reliability of the connected vehicle. It is obvious that 5G technology is pushing the autonomous driving level to the next Level-4 and Level-5 stages. The advanced test performance of the GTS OTA system and Anritsu's integrated MT8000A and MT8821C will be of future-proof value to automotive industry progress."

Dr. Yihong Qi, the Chairman of GTS, emphasized that 5G and V2X technologies will be widely used in the future intelligent-connected-vehicle. GTS is looking forward to collaborating with Anritsu as both companies will make full use of the current technical and marketing advantage. Together we can provide the advanced OTA testing solution for full vehicle wireless communication systems. Anritsu and GTS will strongly support the technology development of global intelligent automotive industry.

Technical Terms

[*1] OTA
Abbreviation for Over the Air technology using radio-wave transmission and reception to measure performance of radio equipment while blocking external radio waves using radio anechoic chamber to reflect radio waves internally within chamber. The 3GPP-specified Compact Antenna Test Range (CATR) supports far-field antenna range tests in the limited chamber space.

[*2] MIMO
Abbreviation for Multi Input Multi Output communications technology using multiple antennas to improve communication speed (throughput).

[*3] Autonomous Driving Level
System of six levels of automobile operation with Level-0 as operation under full human control and Level-5 as fully automated control without human input. Level-2 and Level-3 vehicles are now on the market in Japan with the next target of commercializing Level-5 vehicles able to run without any driver intervention.

[*4] ICV
Abbreviation for Intelligent Connected Vehicle; generic name for vehicles using artificial intelligence and high-level communications technology to drive safely with high effectiveness.

[*5] ADAS
Abbreviation for Advanced Driving Assistant System; generic name for automatic driving assistance systems managing automated braking and sudden-acceleration prevention systems.

[*6] Radiated Two-Stage (RTS)
3GPP TS37.544 V14.5.0-compliant MIMO OTA standard test plan.
