Japan: New regulation for several radio devices used in vehicles 

 

Japan has published a Partial Amendment of the Ordinance on Technical Standards Conformity Certification of Specified Radio Equipment.  

It will add the following types of specified radio equipment such as TPMS, RKE (UHF band), Automotive Radar, In-vehicle Detection Sensor, UWB and Wireless LAN (2.4GHz / 5.2GHz / 5.6GHz / 6GHz (≦25mW)) to the Ordinance as a target for special specified radio equipment which is subject to the self-confirmation system. 

As a result, the certification process will be accelerated due to this switch.
