Yes. When a certified wireless module is used with an antenna covered by its certification, within the specified conditions, customers do not need additional Japanese radio certification for that same radio equipment.
About the module and antenna combination
Certification covers the module and antenna combination, along with conditions such as output power and frequency.
Leafony uses STAF onboard antennas as part of combinations covered by the corresponding module certification. For example, AC08 LTE-M Mary uses the certified combination of Murata Type 1SC and STAF 1019-085A. AC07 LoRa Mary also documents Type ABZ with the same antenna.
AC09 Cat-M1 TY uses a Taiyo Yuden module and STAF 1019-085A. Taiyo Yuden states that using an antenna covered by Japanese radio certification avoids additional certification. The module model, certification number, and corresponding antenna documentation let you check a specific configuration.
Where is the certification marking?
Look on the wireless module itself, mounted on the leaf. Some modules display the Japanese certification mark and number on their metal shield or other surface. “On the chip side” refers to the wireless module body here. The location and marking method vary by product; manufacturer documentation can help you find them.
If assembly hides the marking, disconnect all power before checking it. For small text, take a photo of the module surface with a smartphone or similar camera, zoom in, and compare it with the photos and module name in the leaf’s technical documentation. Distinguish the leaf model printed on the board from the module model and certification number printed on the module.
If you would like to change the antenna
For an external antenna or changes to the radio circuit, use the manufacturer’s certification documents to check whether the new configuration is covered. Alongside connector compatibility, the antenna model and operating conditions are the key points to check.
This explanation concerns Japan’s Radio Act. Overseas certification, cellular subscriptions, and carrier compatibility can be checked separately.
