Postel Certification for Cellular Signal Booster Repeater and DJID Compliance in Indonesia
A cellular signal booster repeater is a telecommunication device designed to amplify and extend mobile network coverage in areas with weak signal reception. These devices are widely used in offices, high-rise buildings, shopping centers, hotels, hospitals, industrial facilities, and remote areas to improve voice and data communication quality.
The repeater works by receiving signals from a cellular operator’s base station, amplifying the signal strength, and retransmitting it to areas that require better coverage. This helps users obtain more stable call quality, internet access, and network connectivity.
Because a repeater actively receives and retransmits cellular radio signals, it is classified as a radio communication device that utilizes licensed frequency spectrum and must comply with Postel or DJID certification requirements before being legally imported, distributed, and marketed in Indonesia.
What Is a Cellular Signal Booster Repeater in Regulatory Context
Under Indonesian telecommunications regulations, a repeater booster is a radio device used to amplify cellular telecommunication signals on specific frequency bands.
The device captures signals from operator base stations, increases signal power, and redistributes the amplified signal through indoor antennas. Because it both receives and retransmits radio signals, its use is strictly regulated to prevent interference with public telecommunication networks.
Every cellular signal booster intended for the Indonesian market must undergo technical evaluation and certification to ensure compliance with applicable frequency allocations and technical standards.
Is Postel Certification Required
Postel certification is mandatory for cellular signal booster repeaters because they transmit and receive radio signals on cellular frequency bands.
Common features found in repeater devices include:
-
Cellular signal amplification
-
RF signal repeater functionality
-
Multi-band cellular support
-
Indoor
Because the device actively transmits and receives radio signals, certification is required before legal market distribution in Indonesia.
Regulations in Indonesia for Telecommunication Devices
Telecommunication device regulations in Indonesia are administered by the Directorate General of Digital Infrastructure (DJID) under the Ministry of Communication and Digital Affairs, formerly known as SDPPI or Postel.
Cellular repeaters are subject to strict regulation because they directly affect licensed operator frequency spectrum. The regulations are intended to prevent interference, maintain national cellular network quality, and ensure proper spectrum utilization.
In certain cases, the deployment of repeater systems may also require coordination or approval under applicable regulations.
Certification Requirements
Companies are generally required to prepare several important documents, including:
-
Business legality documents such as NIB and OSS
These documents are reviewed during the technical and administrative evaluation process.
Certification Process Overview
The certification process begins with product identification and frequency band assessment. Technical and administrative documentation is then reviewed as part of the initial evaluation.
Laboratory testing is conducted on the device’s radio characteristics. Testing may include radio frequency (RF), amplifier gain, transmit power, spurious emissions, electromagnetic compatibility (EMC), occupied bandwidth, receiver sensitivity, and other technical parameters depending on product characteristics.
Once all requirements have been fulfilled and the product successfully passes evaluation, the DJID certificate is issued as official authorization for legal distribution in Indonesia.
Common Challenges in Certification Process
Common challenges include frequency band incompatibility with Indonesian allocations, incomplete technical documentation, regulatory updates, and device specifications that do not meet permitted technical limits.
Because cellular repeaters are highly sensitive radio devices, the technical evaluation process is generally stricter than for standard WiFi products.
Understanding regulatory requirements during product planning can help companies accelerate certification and reduce approval risks.
