Guide to DJID/SDPPI Certification for Thread devices, Thread Border Routers, sensors, smart-home products, and IoT equipment in Indonesia
Thread is an IP-based wireless networking technology increasingly used in smart homes, building automation, smart lighting, locks, sensors, thermostats, controllers, and Internet of Things devices.
Thread uses IEEE 802.15.4 radio technology and provides a low-power IPv6-based mesh network for connected devices. threadgroup.org
For Indonesian Postel/DJID Certification, the commercial term “Thread” needs to be mapped to its actual radio configuration. Minister of Communication and Informatics Decision Number 260 of 2024 includes Low Rate Wireless Personal Area Network IEEE 802.15.4 within Indonesia’s Short Range Device Technical Standards. For 2400–2483.5 MHz LR-WPAN operation, the standard specifies a maximum output power of 20 dBm EIRP. Postel Sertifikasi
The overall certification framework remains Regulation Number 3 of 2024, under which conformity with the applicable Technical Standards is demonstrated through testing and certification. JDIH Komdigi
Thread and IEEE 802.15.4
Thread uses IEEE 802.15.4 as its underlying radio and MAC technology.
It then adds IPv6-based networking to provide IP connectivity across a low-power mesh network. Thread Group describes Thread as an open IPv6-based protocol built on the power-efficient IEEE 802.15.4 MAC/PHY. threadgroup.org
For certification purposes, the word “Thread” alone is therefore insufficient.
The exact radio frequency, transmitter power, chipset or module, antennas, firmware, and enabled radio modes should be identified.
Thread as a Short Range Device
Indonesia’s Short Range Device Technical Standard specifically includes Low Rate WPAN IEEE 802.15.4.
Decision Number 260 of 2024 also provides that conformity with the SRD Technical Standards is demonstrated through telecommunications-equipment certification. Postel Sertifikasi
The terms “low power” and “short range” should therefore not automatically be interpreted as a certification exemption.
2.4 GHz Thread Operation
Thread Group states that Thread uses IEEE 802.15.4 in the 2.4 GHz spectrum and is designed as a globally deployable networking technology. threadgroup.org
Indonesia’s LR-WPAN IEEE 802.15.4 requirements include the 2400–2483.5 MHz band with maximum RF output power of 20 dBm EIRP. Postel Sertifikasi
The manufacturer’s actual frequency and channel configuration should still be confirmed from the product documentation and RF test report.
Thread Transmission Power
Transmission power is an important part of the certification assessment.
For LR-WPAN IEEE 802.15.4 operating at 2400–2483.5 MHz, Decision Number 260 of 2024 specifies ≤20 dBm EIRP. Postel Sertifikasi
The chipset’s nominal output-power specification alone is not enough.
Firmware settings, module integration, antenna gain, and the final enclosure can affect the radio characteristics of the commercial device.
Thread End Devices
Thread end devices may include door sensors, smart locks, lighting products, thermostats, switches, environmental sensors, and other IoT endpoints.
Even where the product is battery powered and has relatively low transmission power, the active IEEE 802.15.4 radio still needs to be included in the certification assessment.
The device’s consumer function does not determine the Postel scope; its actual telecommunications configuration does.
Thread Border Routers
A Thread Border Router connects a Thread mesh to another IP network.
Thread Group and Google documentation explain that Border Routers enable Thread devices to become part of an existing IP network. Google Home Developers
From a certification perspective, a Border Router can therefore be more complex than a simple Thread endpoint.
It may contain IEEE 802.15.4 together with WiFi, Bluetooth, Ethernet, or other communication interfaces.
Thread Border Routers with WiFi
Where a Border Router contains Thread and WiFi, each radio needs to be assessed.
Thread can be mapped against the LR-WPAN IEEE 802.15.4 requirements of Decision Number 260 of 2024, while WiFi/RLAN is covered by a separate technical framework. Minister of Communication and Digital Decision Number 12 of 2025 remains in force for RLAN equipment. Postel Sertifikasi
Ethernet should be distinguished from WiFi because it is a wired interface.
Thread and Bluetooth
Bluetooth is commonly added to Thread devices for commissioning or smartphone-based setup.
A device may use Bluetooth during installation and then communicate primarily through Thread after it joins the network.
Bluetooth and Thread remain separate radio functions even where they operate in the same 2.4 GHz spectrum or share a multi-protocol chipset.
Both interfaces should therefore be included in the technical mapping.
Thread and Matter Are Different
Thread and Matter are closely associated but are not the same technology.
Thread provides network connectivity, while Matter operates at the application layer and can use Thread or other IP networks.
Thread Group explains that multiple application layers can operate over Thread, while Google’s developer documentation notes that many Matter products use Thread as their IP-based wireless mesh network. threadgroup.org
A “Matter compatible” label therefore does not by itself determine the radio-certification scope.
Matter over Thread
A Matter-over-Thread product should be assessed according to the actual radios installed in the final equipment.
A smart lock, for example, may use Thread as its operational network and Bluetooth for commissioning.
A Thread Border Router can contain Thread, Bluetooth, and WiFi.
Certification mapping should therefore follow the physical and enabled radio interfaces rather than simply the Matter ecosystem description.
Thread Modules
Manufacturers can use dedicated Thread modules or multi-protocol wireless modules with existing laboratory reports.
A module report may support certification, but the final equipment still needs to be linked clearly to the tested module.
Current e-Sertifikasi requirements for equipment relying on a module LHU include a block diagram, a photograph showing the installed module location, and a declaration connecting the module with the brand, type, and variant of the final equipment. e-Sertifikasi NextGen
Antennas, firmware, output-power settings, and enabled protocols remain relevant.
Multi-Protocol Chipsets
Modern radio chipsets can support Thread, Zigbee, Bluetooth, and other protocols.
However, chipset capability does not necessarily mean every protocol is enabled in the commercial product.
A product using a chipset capable of both Thread and Zigbee may, for example, enable only Thread and Bluetooth through firmware.
Certification assessment should therefore focus on enabled final-product functionality, rather than simply copying every feature listed on a semiconductor datasheet.
Antenna Configuration
Antenna configuration can affect the final EIRP.
Thread devices may use PCB antennas, chip antennas, dedicated antennas, or shared 2.4 GHz antenna systems.
Because the Indonesian LR-WPAN limit for 2.4 GHz is specified in EIRP, antenna gain and final integration should be compared with the tested configuration. Postel Sertifikasi
The same module installed with a different antenna should not automatically be considered an identical RF configuration.
RF Test Reports
An RF test report provides evidence of the actual radio configuration evaluated by a laboratory.
For Thread/IEEE 802.15.4 equipment, review commonly includes operating frequency, output power, bandwidth, unwanted emissions, antennas, radio modes, and test setup.
Current e-Sertifikasi requirements require a laboratory report from a designated Indonesian testing laboratory or a recognised overseas laboratory under the applicable framework. e-Sertifikasi NextGen
CE or FCC reports can support technical assessment but do not automatically replace Indonesian DJID/SDPPI Certification.
Documents for Thread Certification
For an initial assessment, businesses should prepare:
- Product and label photographs.
- Exact brand and model/type.
- Datasheet and user manual.
- Thread/IEEE 802.15.4 specifications.
- Operating frequency and transmission power.
- Wireless-module or chipset datasheet.
- Antenna information.
- Block diagram.
- Available RF test reports.
Current e-Sertifikasi requirements for a new Certificate also include NIB and OSS access for business applicants, laboratory reports, technical specifications, a Declaration of Conformity, product photographs showing brand and model/type, and other supporting documentation according to the applicant and equipment configuration. e-Sertifikasi NextGen
Multiple Products Using the Same Thread Module
One Thread module may be used across smart locks, sensors, thermostats, switches, and controllers.
Using the same module does not automatically mean that every final product can share one Certificate.
Regulation Number 3 of 2024 links certification to the equipment brand and type. It also provides a specific multiple-variant mechanism for certain equipment below 10 mW with only one identical telecommunications feature where all qualifying conditions are satisfied. JDIH Komdigi
This is a variant-coverage mechanism, not a general low-power certification exemption.
Thread Certification Process
The process should begin by identifying the exact product and every enabled radio interface.
Thread/IEEE 802.15.4, Bluetooth, WiFi, NFC, or other radios can then be mapped together with their operating frequencies, transmission power, modules, antennas, firmware, and existing laboratory reports.
The applicable Indonesian Technical Standards and suitability of existing evidence can then be determined.
Business Certificate applications are processed through the OSS-integrated certification framework and current e-Sertifikasi requirements. JDIH Komdigi
Certificate Period
Under Regulation Number 3 of 2024, the Certificate itself is not time-limited.
However, the Certificate holder may manufacture, assemble, or import the covered equipment for trade and/or use in Indonesia for up to three years from the Certificate issuance date. JDIH Komdigi
Businesses making recurring imports of Thread products should therefore include Certificate issuance dates in long-term regulatory planning.
Labeling After Certification
Certificate holders are also responsible for regulatory marking.
Regulation Number 3 of 2024 provides requirements covering the Certificate number and PLG ID, QR Code, and Warning Sign, while current e-Sertifikasi guidance contains the corresponding implementation requirements. JDIH Komdigi
For small Thread sensors and IoT endpoints, product and packaging space for regulatory marking should ideally be planned before mass production.
Conclusion
Postel Certification for Thread devices should be based on the IEEE 802.15.4 radio used by Thread and every other radio incorporated into the final equipment.
Thread Group describes Thread as an IPv6-based mesh network using IEEE 802.15.4 in the 2.4 GHz spectrum. threadgroup.org
In Indonesia, Decision Number 260 of 2024 regulates Low Rate WPAN IEEE 802.15.4 as a Short Range Device. For the 2400–2483.5 MHz band, its Technical Standard specifies a maximum RF output power of 20 dBm EIRP. Postel Sertifikasi
Certification assessment should therefore review the exact model, Thread radio, Border Router or end-device function, operating frequency, transmission power, modules, antennas, firmware, and RF test reports. Additional Bluetooth or WiFi interfaces should be included in the same overall assessment.
