Certification schemes define the technology differently.
Ultra wideband technology is defined as a short-range radio communication and its most important feature is the use of large frequency ranges with a bandwidth of usually at least 500 MHz.
In order to be able to market a product that uses ultra wideband technology, regulatory approval for the relevant target markets is of course required. One challenge here is the different definition of ultra wideband in the licensing regimes of the various countries. Here are a few examples:
“Equipment using ultra-wideband technology means equipment incorporating, as an integral part or as an accessory, technology for short-range radio communication, involving the intentional generation and transmission of radiofrequency energy that spreads over a frequency range wider than 50 MHz, which may overlap several frequency bands allocated to radio communication services.”
“Ultra wideband transmitter defined as an intentional radiator that, at any point in time, has a UWB bandwidth equal to or greater than 500 MHz or a fractional bandwidth > 0,2”
“The transmit bandwidth (-10 dB) is at least 500 MHz or a fractional bandwidth greater than 0.2. The -10dB bandwidth shall be completely between 3.1 to 10.6 GHz.”
“Device transmit bandwidth (-10 dB) is at least 450 MHz.”
This means that for the countries mentioned, manufacturers have to meet a wide variety of testing requirements, which are defined in the respective standards:
On the basis of our DAkkS accreditation we offer our customers a wide range of regulatory testing according to RED, FCC, ISED, ARIB, and additional certification regimes and are therefore your competent partner for the topic of ultra-wideband.
