Wireless Power Transmission (WPT) in Indonesia has developed very rapidly both in terms of providing infrastructure and supporting technology.
Wireless Power Transmission is especially useful for devices connected with dangerous cables. Wireless Power Transmission in Indonesia is a fairly new technology, but market demand has seen a significant increase.
Along with this development, standardization activities have also been carried out. WPT regulations in several countries also continue to be promoted in the hope of harmonization of rules/laws in the implementation of Wireless Power Transmission in everyday life.
In this article, we will provide information about the challenges of wireless power transmission in Indonesia and certification regulations.
Challenges of Wireless Power Transmission in Indonesia
1. Limited transmission range
At present, WPT technology is generally still effective for short-range applications. In Indonesia, attempts are being made to apply WPT over longer distances, such as in large office spaces or public facilities.
These trials are not without their problems; they still face challenges relating to efficiency. Energy loss increases as the distance between the power source and the receiver grows.
This is what makes it less effective for large areas. To overcome this, additional amplifiers are required to boost the signal.
2. Potential for interference and environmental impact
In principle, any use of electromagnetic waves has the potential to cause interference with other electronic devices operating on similar frequencies. WPT also has the potential to cause the same issue.
In Indonesia, many urban areas are saturated with wireless devices, resulting in a relatively high risk of interference. This needs to be taken into account when devices utilize WPT technology.
3. Energy efficiency still needs to be improved
WPT often has lower energy efficiency compared to the use of cables. This means that some energy is lost as heat during the transmission process. Therefore, innovations are needed to improve the energy efficiency of WPT.
This needs to be taken into account when implementing WPT in Indonesia, given the high electricity tariffs in some regions. For business applications, this will inevitably increase operating costs.
4. High implementation costs
In Indonesia, WPT is currently more commonly used in consumer electronics such as wireless mobile phone chargers. There have not yet been any large-scale implementations.
This is because implementing WPT requires a relatively expensive investment in equipment compared to traditional wired systems. These high costs act as a barrier to its adoption, particularly for small and medium-sized enterprises.
DJID Certification for Wireless Power Transmission (WPT) in Indonesia
In Indonesia, devices equipped with Wireless Power Transmission (WPT) technology are required to undergo type approval certification. This certification is regulated by the DJID (Directorate General of Digital Infrastructure) under the Ministry of Communication and Digital Affairs (KOMDIGI).
This certification is also known as DJID certification. It is conducted to ensure that WPT devices operate safely and do not interfere with other radio frequencies when in use.
WPT technical standards were originally outlined in Ministerial Decree No. 260 of 2024 as part of the broader technical standards for Short-Range Devices (SRD). However, effective February 18, 2025, WPT technical standards are governed by KOMDIGI Ministerial Decree No. 46 of 2025.
In this latest regulation, the technical requirements for WPT devices are set out in greater detail. These include a reorganized and expanded list of permitted frequency allocations, as well as additional provisions regarding antenna use and testing procedures.
WPT devices will undergo testing to ensure they function in accordance with current requirements. Once the devices have been tested, you will receive a Test Results Report. This report serves as the basis for assessing the devices’ compliance before they are permitted to be distributed in Indonesia.
