NBTC Approval for Wireless Devices
TH-Unique · Independent from Thai FDA process · Must be obtained in parallel
When NBTC Review Is Required
Medical devices incorporating any radio frequency communication technology require a separate approval from the National Broadcasting and Telecommunications Commission (NBTC) before commercial supply in Thailand.
This approval is completely independent of the Thai FDA/MDCD registration process and must be obtained as a separate process.
Affected Device Technologies
| Technology | NBTC Required? |
|---|---|
| Wi-Fi (802.11 a/b/g/n/ac/ax) | ✅ Yes |
| Bluetooth (all versions including BLE) | ✅ Yes |
| Cellular (3G/4G/5G/LTE) | ✅ Yes |
| RFID (radio frequency identification) | ✅ Yes |
| Zigbee / Z-Wave / other sub-GHz RF | ✅ Yes |
| ANT / ANT+ | ✅ Yes |
| Satellite communication modules | ✅ Yes |
| NFC (near field communication) | Confirm with NBTC |
| Infrared (IR) — non-RF | ❌ Generally no |
| Wired ethernet / USB only | ❌ No |
NBTC vs Thai FDA — Two Independent Processes
| Aspect | Thai FDA / MDCD | NBTC |
|---|---|---|
| What it covers | Safety and performance of the medical device | Radio frequency spectrum and communications |
| Authority | Ministry of Public Health | Independent telecommunications regulator |
| Application | Via Thai FDA e-submission | Via NBTC portal / direct application |
| Can one substitute the other? | ❌ No — both required | ❌ No — both required |
NBTC Approval Process
The NBTC process typically requires:
- Type approval — testing of the device's RF characteristics against Thai/NBTC standards (based on international standards for the relevant frequency bands)
- Test reports — from NBTC-recognised testing laboratories (Thai labs or foreign labs with mutual recognition)
- Technical specification documentation — frequency bands used, power output, modulation
- Application submission to NBTC
- NBTC approval issued — certificate or approval letter
NBTC-Recognised Standards
NBTC recognises international standards for RF compliance:
- ETSI EN standards (European)
- FCC standards (US) — in many cases accepted with Thai-specific modifications
- IEC/CISPR standards for EMC
Confirm with your NBTC consultant which standards are accepted for your specific device's frequency bands.
Timeline Coordination
| Process | Typical Duration | Recommendation |
|---|---|---|
| Thai FDA product registration | Weeks to months (varies by class) | Start with Thai FDA |
| NBTC type approval | 4–12 weeks | Start simultaneously |
Start both processes in parallel. In many cases, NBTC and Thai FDA approvals can proceed simultaneously with significant time overlap, minimising total time to market.

For wireless medical devices in Thailand, consider engaging a regulatory affairs consultant with experience in both Thai FDA and NBTC processes. The two approval tracks have different documentation and technical requirements.
