Wireless Power Transmission (WPT) or wireless power transmission technology is a technology that allows wireless charging by utilizing electromagnetic waves.
With the increasing use of wireless power transmission technology, the Indonesian government through Decree of the Minister (KEPMEN) No 46 Tahun 2025 from the Ministry of Communication and Digital (KOMDIGI) has established wireless power transmission testing standards to ensure that these devices are safe, efficient, and do not interfere with each other.
This regulation is intended to ensure that all wireless power transmission devices circulating in Indonesia must ensure their quality, safety, and compliance with applicable regulations through testing standards.

New Regulations on Wireless Power Transmission Technology
KEPMEN KOMINFO No 46 Tahun 2025 specifies wireless power transmission operational frequencies to ensure devices work without interfering with other devices.
This control covers radio recurrence prerequisites, greatest transmit control, and testing for wild outflows (spurious emissions).
The following are the standard specifications:
| Radio Frequency Band | Field Strenght | Transmitter Spurious Emission |
| 100 – 148,5 kHz | ≤ 66 dBµA/m at 10 meters distance | EN 300 330 |
| EN 303 417 | ||
| 315 – 405 kHz | ≤ -5 dBµA/m at 10 meters distance | EN 300 330 |
| 1700 – 1800 kHz | ≤ -5 dBµA/m at 10 meters distance | EN 300 330 |
| 6765 – 6795 kHz | ≤ 42 dBµA/m at 10 meters distance | EN 300 330 |
| EN 303 417 | ||
| 13,553 – 13,567 kHz | ≤ 60dBµA/m at 10 meters distance | EN 300 330 |
Wireless Power Transmission Test Method
To ensure that WPT devices meet standards, testing is carried out using methods that refer to international standards:
EN 300 330
This standard is used to measure the performance of devices with low frequencies up to 30 MHz. The main focus is on field strength and electromagnetic compatibility (EMC).
EN 303 417
Used for testing WPT devices operating at higher frequencies. This standard evaluates power transmission efficiency, electromagnetic compatibility, and undesirable emission levels.
Test steps:
- Frequency measurement: Ensure the device is operating within the permitted frequency band.
- Field strength measurements: Carried out at a distance of 10 meters using special tools such as measuring antennas.
- Unwanted emissions test: Ensures additional emissions are below established thresholds.
- Power efficiency evaluation: Measures the efficiency of the device in transmitting power to the receiver.
Benefits of Complying with Wireless Power Transmission Testing Standards
Following the testing standards set by KEPMEN No 46 Tahun 2025 provides many benefits for manufacturers and users:
- Legal compliance: Ensure devices comply with Indonesian government regulations.
- User safety: Reduces health risks from excessive electromagnetic fields.
- Optimum performance: Guarantees the device works efficiently and does not cause frequency interference.
- Consumer trust: Certified products have more value in the market and are more trusted by consumers.
Tips to Ensure Standards Compliance
- Learn the latest regulations: Make past any question you get each detail of the Minister Decree from Communication and Digital No 46 Tahun 2025, tallying specialized prerequisites and test strategies.
- Perform pre-testing: At some point as of late official testing, perform pre-testing to ensure the contraption meets the rules. If you don’t have a measuring instrument, utilize the DJID certification service which gives pre-testing administrations.
- Consult an expert: If this is your to start with time looking for certification, consider utilizing the organizations of experienced DJID certification administrations.
