Recently, the Ministry of Communication and Informatics of Indonesia issued Ministerial Regulation No. 46 of 2025, officially establishing the radio spectrum allocations and technical standards for license-classified Wireless Power Transfer (WPT) devices. This new regulation aims to meet the demands of technological advancement and improve spectrum utilization efficiency. Below is an overview of the key points of the regulation, intended for reference by relevant companies and industry professionals.
The new regulation specifies the following frequency bands
for use in wireless power transfer:
100–148.5 kHz
315–405 kHz
1700–1800 kHz
6765–6795 kHz
13.553–13.567 MHz
The new regulation sets comprehensive technical requirements for
WPT devices, including:
Power Supply: Supports AC or DC power; AC power must comply
with 220V ±10% and 50Hz ±2% conditions.
Non-Ionizing Radiation Safety: Follows ICNIRP guidelines to ensure
radiation levels remain within safe limits.
Electrical Safety: Must comply with SNI IEC 60950-1, IEC 62368-1,
and other relevant international or Indonesian national standards.
Electromagnetic Compatibility (EMC): Devices must meet CISPR 32
or ETSI EN 301 489 series standards, with classifications for fixed,
vehicular, or portable equipment.
Radio Frequency Requirements: Specifies field strength limits and
spurious emission standards for each frequency band (e.g., field
strength for the 100–148.5 kHz band must be ≤ 66 dBµA/m).
WPT devices must use integrated antennas
(Antena Terintegrasi)
and are not permitted to have external control functions
to prevent unauthorized operation.
The new regulation specifies testing methods for various
technical parameters, including electrical safety testing
(based on IEC standards), EMC testing (according to CISPR
32 or ETSI standards), and radio frequency testing (following
EN 300 330 and other relevant standards).
Test reports issued prior to the enactment of the new
regulation will still be accepted, provided their content
does not conflict with the new requirements.
The previous technical standards for WPT under
Regulation No. 260 of 2024 have been repealed and
replaced by the new regulation.
This regulation will take effect on February 18, 2025.
The introduction of this new regulation in Indonesia provides clear guidelines for the application of wireless power transfer technology, while also imposing higher compliance requirements on related companies. It is recommended that companies promptly adjust their product designs to meet the new standards in order to successfully enter the Indonesian market.
