Ultra-Wideband Testing

UWB testing in the frequency range from 3.1 to 10.6 GHz

Provided that the corresponding devices work properly in the relevant frequency range – our exact Ultra-Wideband testing provides clarity.

Different definitions of Ultra-Wideband technology

Currently, the regulatory requirements still differ greatly from one another in some cases. In the EU, for example, the following definition of UWB technology applies:

European Commission and CEPT/ECC

Equipment using Ultra-Wideband technology is equipment that incorporates, as an integral part or accessory, short-range radio link technology that intentionally generates and transmits radio frequency energy. In this case, the technology propagates over a frequency range greater than 50 MHz and there may be overlap of multiple frequency bands allocated to radio transmission services.


In the USA and Canada, on the other hand, the frequency range is defined somewhat differently. Here, the assumption is at least 500 MHz:

USA – Federal Communications Commission (FCC)

Ultrawideband transmitter is defined as a radiator that has a UWB bandwidth (-10 dB) equal to or greater than 500 MHz
or a normalized bandwidth (relative bandwidth in relation to the center frequency) greater than 0.2 at any time.

Canada – Innovation, Science and Economic Development Canada (ISED)

Here the requirement is as well a UWB bandwidth (-10 dB) of at least 500 MHz or a normalized bandwidth greater than 0.2.
The -10dB bandwidth is expected to be entirely between 3.1 and 10.6 GHz.


In Japan, on the other hand, a somewhat lower minimum bandwidth is assumed:

ARIB (Japan)

The transmission bandwidth (-10 dB) is at least 450 MHz.

Regulatory requirements for technology
and Ultra-Wideband (UWB) testing

In order to market a product with Ultra-Wideband technology, regulatory approval is required for the relevant target markets. The following requirements apply to our sample countries:

Europe: Radio Equipment Directive 2014/53/EU:

  • Article 3.1(a) Electrical Safety (EN 62368-1)
  • Article 3.1(a) Human exposure
  • Article 3.1(b) EMV: ETSI EN 301 489-33
  • Article 3.2 Efficient and Effective use of spectrum (radio): e.g ETSI EN 302 065 –x

USA: FCC: Code of Federal Regulations part 15, subpart F

Canada: ISED Rule RSS-220

Japan: MIC, ARIB Standard STD-T91

In preparation for the final certification-relevant tests, we  offer measurements and advice on regulatory requirements during development. In this way, any complications can be identified and resolved at an early stage to enable your products to enter the market as quickly as possible.

After the completed tests, we support you in the subsequent market approval of your products with UWB technology.
