Kepmen Komdigi No. 204 of 2025 now serves as the latest technical reference for Broadband Wireless Access (BWA) devices based on 5G IMT-2020 technology that businesses plan to market, use, or certify in Indonesia.

This regulation covers two main device categories: 5G BWA Subscriber Stations and 5G BWA Base Stations. Manufacturers, importers, distributors, brand owners, and telecommunication businesses need to understand these technical requirements before submitting devices for certification.

What Is Broadband Wireless Access (BWA)?

Broadband Wireless Access, or BWA, refers to broadband internet access technology that uses wireless networks as the transmission medium. This technology allows service providers to deliver internet access without relying entirely on physical cable networks such as fiber optics or DSL.

In simple terms, BWA allows operators or service providers to distribute internet connectivity to users through radio signals.

Common examples of BWA implementation include:

• wireless-based home internet,
• Fixed Wireless Access (FWA),
• indoor and outdoor operator modems,
• internet access in areas without fiber-optic coverage,
• broadband networks for industrial use,
• and 5G-based broadband services.

In the latest technology ecosystem, IMT-2020-based BWA supports 5G implementation, especially for high-speed wireless broadband access services.

Why Is BWA Important in Indonesia?

Indonesia has a vast territory and diverse geographical conditions. These challenges make wired network deployment difficult in some areas, especially rural regions, certain industrial zones, and locations that need fast connectivity without complex cable infrastructure.

BWA can help Indonesia:

1. Accelerate equal access to internet services.
2. Reduce dependence on cable infrastructure.
3. Support national digital transformation.
4. Expand broadband service coverage.
5. Support 5G and Fixed Wireless Access implementation.
6. Meet connectivity needs in industrial and business sectors.

For this reason, the government established technical standards to ensure that BWA devices distributed and used in Indonesia meet safety, compatibility, quality, and radio frequency spectrum efficiency requirements.

Purpose of Kepmen Komdigi No. 204 of 2025

Kepmen Komdigi No. 204 of 2025 provides a technical reference for BWA devices that use IMT-2020 technology standards.

In general, this regulation aims to:

1. Ensure that 5G BWA devices comply with applicable technical standards.
2. Support efficient use of radio frequency spectrum.
3. Maintain device compatibility with Indonesia’s national telecommunication networks.
4. Minimize the potential for harmful interference.
5. Ensure compliance with electrical safety requirements.
6. Ensure compliance with electromagnetic compatibility (EMC) requirements.
7. Support the telecommunication device certification process in Indonesia.

For businesses, this regulation plays an important role because it serves as one of the references for the DJID/SDPPI/Postel certification process for 5G BWA devices.

What Devices Does This Regulation Cover?

Kepmen Komdigi No. 204 of 2025 specifically covers two categories of IMT-2020-based BWA devices.

1. 5G BWA Subscriber Station

A Subscriber Station, or 5G BWA SS, refers to a device located on the user side. It functions as customer terminal equipment that receives and transmits broadband connectivity through a 5G BWA network.

Devices that may fall under this category include:

• 5G BWA customer devices,
• 5G modems or access terminals,
• Fixed Wireless Access devices,
• customer premises equipment (CPE),
• and other broadband access devices that operate under IMT-2020 standards.

2. 5G BWA Base Station

A Base Station, or 5G BWA BS, refers to a network device that provides broadband access services to subscriber devices. Operators or telecommunication network providers typically use this type of device.

The Base Station plays an important role in BWA services because it acts as the transmission and reception point between the operator’s network and subscriber devices.

Use of IMT-2020 Technology

This regulation adopts International Mobile Telecommunications-2020, or IMT-2020, as the applicable technology standard. IMT-2020 serves as the international technology framework for 5G networks.

By applying IMT-2020 standards, Indonesia requires BWA devices to meet technical specifications that align with the modern 5G ecosystem.

This requirement helps ensure that devices operate reliably, remain compatible with national networks, and avoid harmful interference with other telecommunication devices or services.

Use of the n50 Frequency Band

One of the key technical points in Kepmen Komdigi No. 204 of 2025 involves the use of the n50 frequency band.

For 5G BWA Subscriber Stations, the regulation sets the applicable radio frequency range at 1432 MHz to 1517 MHz with TDD, or Time Division Duplex, mode.

For 5G BWA Base Stations, the technical operating requirements specify the use of the 1432 MHz to 1512 MHz radio frequency range.

Manufacturers, importers, vendors, and certification applicants need to pay attention to this distinction to ensure that their device specifications meet the applicable requirements.

Power Supply Requirements for Subscriber Stations

5G BWA Subscriber Stations must use a wired power source. The device may draw power directly from an AC connection or through an AC/DC converter connected to the electrical grid.

The regulation does not allow 5G BWA Subscriber Stations to use batteries as their main power source. Companies should consider this requirement from the product design stage, model selection stage, and certification preparation stage.

In other words, manufacturers must design 5G BWA SS devices as fixed equipment powered through an appropriate electrical source.

Electrical Safety and EMC Requirements

5G BWA devices must meet electrical safety and electromagnetic compatibility (EMC) requirements.

Electrical safety requirements help ensure that devices remain safe for users and the surrounding environment.

EMC requirements help ensure that devices do not generate harmful electromagnetic interference and can operate properly alongside other electronic equipment.

This regulation references several standards, including:

• SNI IEC 62368-1,
• SNI IEC 60950-1,
• IEC 62368-1,
• IEC 60950-1,
• SNI CISPR 32,
• IEC CISPR 32,
• and relevant ETSI EN standards according to the device category.

Radio Frequency Testing Parameters

In addition to electrical safety and EMC, 5G BWA devices must also meet radio frequency testing parameters.

These parameters may include:

• output power,
• minimum output power,
• spectrum emission mask,
• adjacent channel leakage ratio (ACLR),
• transmitter spurious emissions,
• receiver sensitivity,
• receiver spurious emissions,
• blocking characteristics,
• and other radio parameters according to the device category.

These tests help confirm that the device operates according to technical standards and does not interfere with radio frequency spectrum usage.

Related Regulatory Framework

Kepmen Komdigi No. 204 of 2025 forms part of Indonesia’s broader telecommunication regulatory framework, especially regulations related to telecommunication device certification and radio frequency spectrum usage.
