In Singapore, radio communication devices require mandatory type approval from the Info-communications Media Development Authority (IMDA) before they can be imported, sold, or used. This process ensures that devices meet local technical standards to prevent interference within the radio frequency spectrum. Whether for consumer electronics, industrial equipment, or telecommunications devices, obtaining IMDA approval is essential for market access in Singapore.
The IMDA manages the allocation of radio frequency bands in Singapore and ensures that all wireless devices comply with the country’s regulatory standards. These standards are designed to protect the integrity of Singapore’s radio frequency spectrum and to ensure devices operate safely and efficiently without interfering with other communication systems.
IMDA’s regulatory framework draws from international standards set by bodies such as the International Telecommunication Union (ITU) and Association of Southeast Asian Nations (ASEAN). Devices must conform to these standards to ensure interoperability and to meet Singapore’s specific frequency allocations and power limits.
Radio type approval is required for a variety of devices that use radio frequency (RF) communication. These include:
Products using technologies like Wi-Fi, Bluetooth, Zigbee, RFID, and cellular communication all require certification to operate legally within Singapore.
Devices seeking approval must comply with the frequency bands and power limits defined by IMDA. These frequency allocations are harmonized with international standards but also include country-specific considerations for local conditions. The following are examples of commonly used frequency bands in Singapore:
Devices must stay within the allowed power output, which can vary by frequency band and intended application.
This standard applies to devices like cellular base stations, repeaters, and amplifiers. It ensures that these systems operate within the approved frequency bands and power limits, maintaining compatibility with Singapore’s cellular networks (e.g., 3G, 4G, 5G). Devices regulated under this standard include base stations used by mobile network operators and communication repeaters for signal enhancement.
Example: A 5G base station installed to provide network coverage must comply with IMDA TS CBS Is to ensure device doesn’t interfere with other communication systems.
This standard governs land mobile radio systems such as walkie-talkies, two-way radios, and emergency communication systems. It sets the technical specifications for land mobile radios to ensure efficient use of spectrum and prevent interference with other services.
Example: Walkie-talkies used for public safety, transportation, or logistics must comply with IMDA TS LMR to ensure they operate within the designated frequencies.
This standard applies to short-range, low-power devices like Bluetooth devices, Wi-Fi routers, wireless microphones, and RFID systems. It ensures that these devices operate within the designated short-range frequency bands and power levels, preventing interference with other nearby devices and services.
Example: A wireless microphone used in an auditorium or an RFID reader at a warehouse would need to comply with IMDA TS SRD to ensure it operates within the legal frequency range.
This standard governs the operation of IoT devices, such as smart meters, connected industrial equipment, and smart home systems. It covers the technical specifications for these devices to ensure they operate efficiently within the designated frequency bands and meet cybersecurity requirements, particularly for devices that handle sensitive data.
Example: A smart meter transmitting utility usage data over a wireless network would need to comply with IMDA TS IOT.
This standard applies to devices that process or transmit sensitive data and need to adhere to strict cybersecurity requirements. Devices like routers, IoT gateways, and smart home devices fall under this standard if they handle sensitive information, ensuring data encryption, access control, and protection from unauthorized access.
Examples of Devices:
This standard governs cellular mobile terminals, which are devices that connect to mobile networks (2G, 3G, 4G, or 5G). It ensures that these devices operate within the approved frequency bands and power limits, and do not interfere with other communications.
Examples of Devices:
IMDA provides different registration schemes depending on the device type, complexity, and associated risk:
Covers short-range/low-power devices (SRD/LPD) and complex multi-line equipment, including PABX, WLAN, Bluetooth devices, and RFID.
Devices registered under ESER can self-declare compliance without needing verification by IMDA, making the process faster and cost-effective.
Applies to mobile terminals (3G/LTE/5G) and broadband access equipment (ADSL, cable modems).
Devices registered under SER must also self-declare compliance with IMDA standards.
Mandatory for more complex devices like land mobile radio, mobile base stations, IoT base stations, and TV white space devices.
Registration under GER requires certification by IMDA-recognized labs or evaluation by IMDA. This is a more rigorous process due to the higher risk and complexity of these devices.
Manufacturers based outside of Singapore are required to appoint a local representative to manage the certification process. The representative is responsible for handling submissions and communicating with IMDA.
For full Telecom Equipment Type Approval or Radio Communication Equipment certification for commercial distribution, a local holder is generally required.
Testing for compliance with IMDA TS CD-SEC and IMDA TS CMT must be conducted by recognized international labs.
The process to obtain IMDA Certification involves the following steps:
Determine whether the device requires standard radio type approval, or if it also needs to comply with IMDA TS CD-SEC (cybersecurity) or IMDA TS CMT (cellular network compatibility).
Devices must undergo testing at an IMDA-accredited lab, or the manufacturer must provide test reports from recognized international labs. Testing will verify compliance with frequency usage, transmission power, cybersecurity protocols (if applicable), and cellular network requirements.
For IMDA TS CD-SEC, devices must pass cybersecurity assessments, ensuring data encryption and protection measures are in place.
For IMDA TS CMT, cellular devices must be tested for compatibility with Singapore’s 4G and 5G networks, ensuring they operate within the approved frequency bands and power limits.
Submit all required documents, including test reports, technical specifications, and security documentation (for IMDA TS CD-SEC devices), through the License One portal.
IMDA will review the submitted documents and test results. Once approved, the product will be granted type approval, and the device will be listed in IMDA’s Equipment Database.
When importing devices that include components like routers, it is important to understand how IMDA treats host devices and their components for regulatory approval.
If the host device and router are integrated into a single system, the entire unit must be approved by IMDA. Even if the router is already IMDA-approved under IMDA TS CMT (for cellular mobile terminals), the host device may still require approval—especially if it introduces new functionalities such as:
If the router and host device are separate units and can operate independently, re-approval of the router may not be required, provided it is already IMDA-approved. However, the host device will need its own approval if it has radio communication capabilities, such as Wi-Fi, Bluetooth, or cellular functions.
Example: A host device that serves as a platform for the router but doesn’t emit any radio frequencies may not require additional IMDA approval. If the host device has its own RF functions, such as a Wi-Fi transmitter, it would need separate approval under the relevant IMDA standard.
If either the host device or the system handles sensitive data—such as personal, medical, or industrial information—compliance with IMDA TS CD-SEC (cybersecurity) may be necessary. Even if the router is already approved, the system’s overall security must meet IMDA’s cybersecurity requirements.
Example: A device handling sensitive industrial data, even with an IMDA-approved router, would still need to comply with IMDA TS CD-SEC to ensure that proper data protection protocols are in place.
In Singapore, all radio communication devices must comply with the labeling requirements set by the Info-communications Media Development Authority(IMDA). Labeling ensures that devices meet Singapore’s technical, regulatory, and cybersecurity standards, and that they are properly identified for compliance
verification during sale, use, or importation.
Since 4 April 2012, IMDA has allowed the use of **electronic compliance labels**on registered telecommunication equipment.
