The Ministry of Internal Affairs and Communications (MIC) in
Japan has launched a public consultation, starting on September 7, 2024. The
consultation focuses on a draft report from the Land Radio Communications
Committee, which outlines specific technical requirements for tire pressure
monitoring systems (TPMS) and remote keyless entry systems operating in the 433
MHz band. This is part of broader guidelines designed to regulate low-power
radio systems in Japan. The public is invited to provide comments on the draft
until October 7, 2024.
Importance of the Consultation
The 433 MHz band plays a vital role
in ensuring the reliable operation of various low-power devices, including TPMS
and remote keyless entry systems. These systems are crucial for both automotive
safety and consumer convenience. Given their growing use in modern vehicles,
the consultation aims to ensure that Japan’s regulatory framework remains
up-to-date with global technological advancements.
MIC Certification and Giteki Mark:
Entry Requirements for Wireless Products in Japan
To
enter the Japanese market with wireless products, manufacturers must comply
with MIC certification standards and obtain the Giteki mark, which
certifies that a device meets Japan’s radio frequency regulations. The
certification process depends on the type of wireless equipment, and Japan
distinguishes between Specified Radio Equipment (SRE) and Special
Specified Radio Equipment (SSRE).
For
SSRE, the certification process is simplified. Manufacturers can submit a declaration
of conformity along with properly prepared test reports through a
Japan-based representative. This ensures that products meet the required
technical standards without extensive testing. However, for SRE, testing must
be carried out by a Registered Certification Body (RCB), and the
approval process is more detailed, especially for products to be sold in large
quantities.
- Type Certification: For mass-produced
equipment, only sample devices undergo testing by the RCB. Once approved,
manufacturers are responsible for marking the products with the Giteki
label. - Small Batch Testing: For smaller
quantities, each product must be tested and marked by the RCB.
Testing
and Certification Support for Low-Power Devices
In
addition to the standard regulatory requirements, voluntary schemes are
available for testing High-Frequency Devices and Extremely Low-Power
Devices. These testing protocols help ensure that devices operate safely
within designated frequency bands without causing interference. Testing
services and certification processes can be fully managed by service providers,
ensuring a smooth approval process for wireless products in Japan.
