The Directorate General of Digital Infrastructure (DJID) has officially added the new technical regulation of KEPMEN KOMDIGI No. 45 year 2025 to the application system. This new technical regulation is about technical standards of cellular telecommunications devices based on global system for mobile communications and international mobile telecommunications-2000 standards. The ministerial decree number 45 has been promulgated since 18 February 2025 and should come into effect 6 months after its promulgation. Therefore, this new technical regulation has officially come into effect on 18 August 2025. The enactment of this ministerial decree will replace the previous technical regulation for the same standards.
In this article we will discuss all about the new technical standards of 2G and 3G telecommunications devices based on global system for mobile communications dan international mobile telecommunications-2000 standards and its impact on ongoing applications.
General information of KEPMEN KOMDIGI No. 45/2025
In general, the technical regulation of KEPMEN KOMDIGI No. 45 year 2025 is a local standard used for local testing and type approval certification in Indonesia. This technical regulation describes two types of cellular technology, which are 2G technology based on the global system for mobile communications standard and 3G technology based on the international mobile telecommunications-2000 standard.
Each type of cellular technology is applicable to three categories of telecommunications equipment, which are base stations, subscriber stations, and repeaters. The implementation of the technical regulation of KEPMEN KOMDIGI No. 45 year 2025 will also replace the previous technical regulation of PERDIRJEN SDPPI No. 5 year 2019. Furthermore, in this article, we will only discuss the technical requirements for cellular telecommunications devices under the subscriber station category.
General technical requirements for 2G and 3G cellular telecommunications devices
Subscriber stations of 2G and 3G cellular technologies are a type of cellular telecommunications equipment based on radio access technology for the global system for mobile communications and international mobile telecommunications-2000 network, and hereinafter referred as SS GSM and SS IMT-2000 respectively.
General technical requirements for telecommunications equipment of SS GSM and SS IMT-2000 that have to be met in the type approval certification include power supply, non-ionizing radiation, electrical safety, electromagnetic compatibility and radio frequency requirements.
Power supply requirements
Telecommunications equipment of SS GSM and SS IMT-2000 can be powered by AC or DC power. For SS GSM and SS IMT-2000 powered by AC power, all parameter benchmarks must be met when using a power supply within the AC voltage range of 220 V ± 10% and a frequency of 50 Hz ± 2%. When using an external power supply such as AC/DC power converter, the external power supply must not affect the SS GSM and SS IMT-2000’s ability to meet all technical parameter benchmarks.
Non-ionizing radiation requirements
Non-ionizing radiation is typically a form of low-frequency electromagnetic radiation produced by ICT devices attached to the human body. The amount of electromagnetic radiation absorbed by the human body is typically measured during Specific Absorption Rate (SAR) testing.
Electrical safety requirements
Electrical safety assessment for SS GSM and SS IMT-2000 telecommunications equipment have to meet two parameters of electrical safety below:
- Over voltage or electrical strength or dielectric strength
- Leakage current or touch current
Electrical safety assessment for SS GSM and SS IMT-2000 telecommunications equipment shall meet the requirements specified in standards of IEC 62368-1 or IEC 60950-1.
Electromagnetic compatibility (EMC) requirements
SS GSM and SS IMT-2000 telecommunications equipment should be classified as:
- Fixed equipment: devices installed permanently and powered by AC power
- Vehicular equipment: devices used in vehicles and powered by the vehicle’s main battery
- Portable equipment: devices designed for portable use and powered by batteries
SS GSM and SS IMT-2000 telecommunications equipment have to meet EMC immunity and emission requirements. The EMC emission parameters that have to be met are:
- EMC radiated emissions in the enclosure of ancillary equipment
- EMC conducted emissions on AC, DC, or AC/DC converter ports
- EMC conducted emissions on telecommunications network ports
Each EMC emission parameter needs to be classified whether it is class A or class B according to the standard of IEC CISPR 32 or ETSI EN 301 489-1.
Radio frequency requirements for 2G cellular telecommunications devices
SS GSM telecommunications equipment can only operate in the following radio frequency bands:
| Band | Uplink (MHz) | Downlink (MHz) | Duplex Mode |
| GSM 850 | 824–849 | 869–894 | FDD |
| P-GSM 900 | 890–915 | 935–960 | FDD |
| E-GSM 900 | 880–915 | 925–960 | FDD |
| R-GSM 900 | 876–915 | 921–960 | FDD |
| ER-GSM 900 | 873–915 | 918–960 | FDD |
| DCS 1800 | 1710–1785 | 1805–1880 | FDD |
SS GSM output power must comply with the limits in the standards of ETSI EN 301 511, ETSI TS 151 010-1, and/or ETSI TS 151 010-1. The limits for conducted transmitter spurious emission values for SS GSM operating in the radio frequencies 900 (P-GSM 900 and E-GSM 900), 900 (R-GSM 900 and ER-GSM 900), and 850 (GSM 850) are set out in the standards of ETSI TS 151 010-1 or ETSI EN 301 511.
Radio frequency requirements for 3G cellular telecommunications devices
SS IMT-2000 telecommunications equipment can only operate in the following radio frequency bands:
| Band | Uplink (MHz) | Downlink (MHz) | Duplex Mode |
| I | 1920–1980 | 2110–2170 | FDD |
| VIII | 880–915 | 925–960 | FDD |
SS IMT-2000 output power must comply with the limits set forth in standards of ETSI EN 301 908-2 or ETSI TS 134 121-1. Transmitter spurious emissions, applicable to frequencies greater than 12.5 MHz from the carrier center frequency, must not exceed the values set forth in standards of ETSI EN 301 908-2 or ETSI TS 134 121-1.
Impact on ongoing type approval certification
As already mentioned before, the technical regulation of KEPMEN KOMDIGI No. 45 year 2025 has been valid since 18 August 2025. So, telecommunications devices with 2G and 3G cellular features shall use this new technical regulation for DJID certification starting 18 August 2025 onwards. Every application that does not use this new technical regulations, the authority will reject the application.
Conclusion
It is important for applicants to stay updated with any changes in Indonesia type approval technical regulations, such as the issuance of the technical regulations for 2G and 3G cellular features. Generally, the implementation of new technical regulations can cause confusion in the initial process. To facilitate this adjustment period, applicants can consult with a type approval service company. Therefore, feel free to send an email to info@narmadi.com if you have any questions about this new technical regulation.
