4G LTE Device Certification in Indonesia: A Radio Frequency Guide - Cerapproval - Indonesia SDPPI Certification & Type Approval Agency

The 4G LTE (Long Term Evolution) network is the backbone of data communication in Indonesia, both for personal and industrial needs. To ensure interoperability and avoid signal interference, the use of radio frequencies is strictly regulated by the Ministry of Communication and Digital Affairs (Komdigi) through official regulations. In accordance with the regulations set by the government regarding Minister of Communication and Digital Affairs Decision No. 352 of 2024, which establishes technical standards for communication devices and/or mobile telecommunication equipment, particularly those related to the use of 4G technology.

1. 4G Frequency Spectrum in Indonesia

In Indonesia, 4G LTE (Long Term Evolution) technology operates on several frequency bands, including 800 MHz, 900 MHz, 1800 MHz, 2100 MHz, and 2300 MHz. Several mobile operators use a combination of these frequencies to provide optimal coverage and speed. According to Komdigi regulations, 4G LTE frequencies in Indonesia are only permitted for use on several main bands, including:

4G LTEKOMDIGI DEGREE NO. 352 OF 2024	BAND	UP LINK	DOWN LINK
	(1) 2100 MHz	1920-1980 MHz	2110-2170 MHz
	(3) 1800 MHz	1710-1785 MHz	1805-1880 MHz
	(5) 800 MHz	824-849 MHz	869-894 MHz
	(8) 900 MHz	880-915 MHz	925-960 MHz
	(28) 700 MHz	703-748 MHz	758-803 MHz
	(31) 450 MHz	452,5-457,5 MHz	462,5-467,5 MHz
	(40)	2300-2400 MHz	2300-2400 MHz

This division aims to maximize network capacity and ensure service quality.

2. Compliance and Certification

All telecommunication devices operating on 4G networks must be certified by the Directorate General of Resources and Postal and Informatics Devices (Ditjen SDPPI). This certification ensures devices comply with technical standards, including official frequency allocations.

Cerapproval, as a certification agency, assists manufacturers and importers through the process efficiently — from device testing to the issuance of official SDPPI / DJID certificates.

3. Consequences of Non-Compliance

Operating devices outside the official frequency bands can cause service disruptions and lead to administrative sanctions. In some cases, non-compliant devices may be banned from entering the market.

4. Tips for Manufacturers & Importers

Ensure that the device supports Indonesia’s official 4G bands.
Perform compatibility tests before distribution.
Use a testing laboratory registered with SDPPI (DJID).
Complete the technical documentation correctly to avoid rejection.
Use consulting services or agencies such as Cerapproval to expedite certification.

By following these guidelines, manufacturers and importers can ensure their 4G devices are ready to enter the Indonesian market in accordance with applicable standards.
