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

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
  • Proof of Authorisation

No physical product sample submission is required.

Indicative Timeline

Class AApproximately 1–2 months from submission

Additional time may be required if NBTC requests supplementary documents during review.
