Ultra-wideband (UWB) is a radio technology used especially for short-range radio communication. It is used in a wide frequency range and offers various advantages and applications: very high data transmission rates over a short distance, energy efficiency with accurate positioning and communication that is difficult to locate.
Provided that the relevant equipment operates correctly in the relevant frequency range – our precise ultra-wideband testing bring clarity.
At present, the regulatory requirements still differ considerably from one another. In the EU, for example, the following definition of UWB technology applies:
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:
Ultra-wideband transmitter is defined as a radiator that has a UWB bandwidth equal to or greater than 500 MHz or a normalised bandwidth greater than 0,2.
The transmission bandwidth (-10 dB) shall be at least 500 MHz or a fractional bandwidth greater than 0,2 and the bandwidth of -10dB shall be entirely between 3,1 and 10,6 GHz.
In Japan, on the other hand, a slightly lower minimum bandwidth is assumed:
The transmission bandwidth (-10 dB) is at least 450 MHz.
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:
USA: FCC: Code of Federal Regulations part 15, subpart F
Canada: ISED Rule RSS-220
Japan: MIC, ARIB Standard STD-T91
In our test laboratory in Germany we carry out ultra-wideband testing based on various international specifications. These specifications include among others:
Electromagnetic compatibility and Radio spectrum Matters (ERM); EMC standard for radio equipment and services; Part 33: Specific conditions for Ultra-Wideband (UWB) communications devices
Short Range Devices (SRD) using Ultra-Wideband (UWB) Technology; Harmonised Standard covering the essential requirements of article 3.2 of the Directive 2014/53/EU; Parts 1, 2, 3 and 4
UWB Intentional Radiators (FCC Part 15, Subpart F) Ultra-Wideband Operation
Devices Using Ultra-Wideband (UWB) Technology
Once the tests have been completed, we support you in the subsequent market approval of your products with UWB technology.
