Ultra-Wideband Testing

Testing in the 3,1 to 10,6 GHz frequency range

Provided that the relevant equipment operates correctly in the relevant frequency range – our precise Ultra-Wideband testing bring clarity.

Different definitions of Ultra-Wideband technology

At present, the regulatory requirements still differ considerably from one another. In the EU, for example, the following definition of UWB technology applies:

European Commission and CEPT/ECC

Equipment using Ultra-Wideband technology is equipment which incorporates, as an integral part or as an accessory, short-range radio link technology which intentionally generates and transmits radio frequency energy. In this context, the technology spreads over a frequency range exceeding 50 MHz and several frequency bands allocated to radio transmission services may overlap.


In the USA and Canada, however, the frequency range is defined somewhat differently. Here, one assumes at least 500 MHz:

USA – Federal Communications Commission (FCC)

Ultra-Wideband transmitter is defined as a radiator that has a UWB bandwidth equal to or greater than 500 MHz or a normalized bandwidth greater than 0,2.

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

The transmission bandwidth (-10 dB) shall be at least 500 MHz or a fractional bandwidth greater than 0,2 and the bandwidth of -10 dB shall be entirely between 3,1 and 10,6 GHz.


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

ARIB (Japan)

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

Regulatory requirements for the technology and Ultra-Wideband Testing

Anechoic chamber in which electrical devices undergo ultra wideband tests.

In order to market a product with Ultra-Wideband technology, official 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) EMC: 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
