Class A
NBTC Certification for UWB Devices
Ultra-wideband (UWB) is a short-range radio technology that operates across an exceptionally wide frequency range — 1.6 to 10.6 GHz — at extremely low power levels. In Thailand, UWB devices require Class A Registration under the NBTC framework, regardless of use case or application.
What UWB Is Used For
- Indoor positioning — centimetre-level location accuracy in warehouses, hospitals, and industrial facilities
- Asset tracking — real-time tracking of equipment, tools, and inventory in complex environments
- Radar imaging — through-wall detection, ground-penetrating radar, and medical imaging applications
- Secure access and keyless entry — automotive passive entry systems that use UWB to prevent relay attacks
- Device-to-device ranging — spatial awareness between consumer electronics
Certification Requirements
| Application | Frequency Band | Certification | Reference |
|---|---|---|---|
| Ultra-wideband (UWB) | 1.6–10.6 GHz | Class A | NBTC TS 1034-2561 |
The transmit power limit for UWB is expressed as a spectral density — the maximum power allowed per MHz of occupied bandwidth — rather than as a single total power figure. Compliance must be demonstrated across the entire operating frequency range of the device.
Required Documents
- Technical specification or datasheet including wireless communication details
- Product photos
- Test reports from accredited laboratories
- ISO/IEC 17025 accreditation certificate and laboratory scope
- Authorised declaration
No physical product sample submission is required.
Indicative Timeline
Class AApproximately 5 weeks from submission
Additional time may be required if NBTC requests supplementary documents during review.
