TOYO appointed as a RanLOS distributor in United States, Japan and China

Launch of Swedish “Automotive CATR Solution“ installable in existing EMC testing anechoic chambers

Fremont, Calif. – June 25, 2020 – TOYOTech, a wholly owned subsidiary of TOYO Corporation (Tokyo Stock Exchange 1st Division, Code: 8151) announced the launch of the “Automotive CATR*1 (compact range) Solution” from RanLOS AB (HQ: Gothenburg, Sweden), following the conclusion of a distribution agreement for marketing RanLOS products in the United States, Japan and China. This solution offers a method to evaluate the quality of on-vehicle wireless communication devices.

The integration of automotive and communication technologies has been advancing with the increased needs  for on-vehicle wireless data communication to improve safety, streamline traffic, and offer infotainment and internet access services. It is expected that higher-quality communication – larger capacity and smaller delay – will be required to advance the progress of autonomous driving/Advanced Driver Assistance System technologies and to offer better-quality services.

While wireless communication testing has become a part of the routine in the mobile products and service development process to improve quality and guarantee performance in the communication industry, testing methodologies and standards for wireless communication functions on automobiles has yet to be established. When you test on-vehicle wireless communication equipment, the entire vehicle with the communication equipment mounted on needs to be tested instead of testing the equipment alone. In addition, automotive manufacturers are seeking a practical way to test while simulating actual traffic environments to reproduce more realistic communication.

RanLOS develops the “Automotive CATR Solution” by applying to automotive testing the accurate and highly reproducible test method that has been used in the communication industry. By deploying the solution in your existing anechoic chamber, you can test wireless communication performance of automobiles while simulating realistic communication on highways or in cities.

Its compact and easy-to-install design and reduced reflection from the floor and walls with the use of plane waves to generate electromagnetic fields allow it to be installed in an existing anechoic chamber for EMC testing. When it is placed on a turntable with a chassis dynamometer, OTA (Over-The-Air) testing can be conducted in either driving or regeneration mode and with ADAS function running.

This solution can be used for functional testing of safety systems and autonomous driving systems as it supports V2X communication, which is expected to spread widely in the future. In addition, the easy setup helps reduce test time.

The “Automotive CATR Solution” will offer a practical method to test wireless communication equipment on automobiles in a realistic environment, contribute to improved wireless communication quality and shorten development cycles for automobiles.


Automotive CATR Solution Features

・ OTA test for on-vehicle wireless communication equipment in an existing EMC anechoic chamber

・ Test zone large enough for vehicle body size (8.2ft diameter) allowing testing of antenna installed at almost any location on the vehicle

・ Test in either drive or regeneration mode by using a turntable with a chassis dynamometer

・ Combined test of ADAS and V2X communication quality

・ Easily changeable test frequency (simply by changing the antenna array at the reflector focus, no re-alignment is necessary)

・ Substantially reduced or eliminated capital cost – you do not need to build an expensive anechoic chamber and can use an existing one instead.


About RanLOS

RanLOS AB was founded in 2015 by Professor Per-Simon Kildal at Chalmers University of Technology in Gothenburg, Sweden. RanLOS has applied for a patent of Random Line-of-Sight measurement set-up OTA (Over The Air), to be used for testing of communication with cars. The solution is based on research from Chalmers University of Technology and includes antennas from Gapwaves AB. Professor Per-Simon Kildal has commercialized a number of inventions. The Comhat antenna has been sold in over one million units and is deployed worldwide in Ericsson’s minilink. Professor Kildal also founded Bluetest AB which has a track record of delivering OTA test systems based on reverberation chambers to all major players in the telecom industry. RanLOS Website:
