OKI Engineering Co., Ltd. (President: Hiroyuki Oba; Headquarters: Nerima-ku, Tokyo; hereinafter OEG), which provides technical services for reliability evaluation, environmental testing, and EMC testing within the OKI Group, will launch domestic automotive EMC immunity testing services starting June 5, 2026, using AWGN to reproduce signals up to 7.125GHz, compatible with Wi-Fi 6E. In response to the widespread adoption of Wi-Fi 6E devices and the sophistication of testing conditions required by European automotive manufacturers, OEG will enable the high-frequency band testing of automotive equipment—previously forced to be conducted in overseas laboratories—within Japan. This initiative will alleviate the financial burden on automotive equipment manufacturers while contributing to shortened evaluation and development periods. OEG aims to achieve 100 million yen in revenue for fiscal year 2026 through this expansion.
In recent years, with the proliferation of Wi-Fi 6E-enabled devices that realize high-speed, stable communication environments, there is an increasing demand for immunity testing using AWGN as a wave that simulates actual environments in the frequency band up to 7.125GHz within the radio environment surrounding automotive equipment. Since 2023, European automotive manufacturers have begun making testing requirements based on their proprietary standards related to Wi-Fi 6E, and automotive equipment manufacturers in Japan are also expected to face demands for testing that comply with the standards of export destinations. On the other hand, automotive equipment manufacturers that do not possess such testing equipment themselves have been forced to use overseas testing laboratories, creating issues with financial burdens and extended periods required for evaluation and development.
OEG has previously supported automotive EMC immunity testing from 9kHz to 6.0GHz. Leveraging facility operation knowledge and abundant testing achievements accumulated over approximately 20 years in automotive EMC testing, OEG has expanded its facilities ahead of other commissioned testing laboratories in Japan, extending the supported frequency range for AWGN-based testing to a maximum of 7.125GHz. This makes it possible to correspond to radiated immunity testing and portable transmitter testing in the frequency range required by European automotive manufacturers. As customers can conduct tests domestically, they can streamline product development through the reduction of coordination loads associated with using overseas testing laboratories, cost savings, and shortened development periods.
As a testing laboratory compliant with ISO/IEC 17025, OEG plans to sequentially respond to frequency expansion and the sophistication of testing conditions in various EMC tests. Going forward, the company will continue to respond promptly to the EMC testing needs of diverse electronic devices, starting with the automotive field, and support the streamlining of product development as well as the improvement of quality and reliability.
Sales Plan:
Standard Price: Individual Quotation
Sales Target: 100 million yen for FY2026
Start Date: June 5, 2026

FAQ
What are the features of the EMC resistance test service for in-vehicle devices that OKI Engineering is starting to provide?
This is a test service that can irradiate up to 7.125 GHz of Wi-Fi 6E compatible radio waves, simulating real-world environments using AWGN.
What benefits do in-vehicle device manufacturers gain from using this service?
By conducting tests domestically instead of using overseas test facilities, the service reduces adjustment burdens, cuts costs, and shortens evaluation and development periods.
Why is testing up to 7.125 GHz necessary?
This is due to the spread of Wi-Fi 6E compatible devices and the increasing test requirements based on in-house standards by European automakers from 2023 onwards.
When will the service start?
The service will start on June 5, 2026.
What is OEG's sales target for this service in fiscal year 2026?
OEG aims for 1 billion yen in sales for this service in fiscal year 2026.
