Report on Measurement Campaigns for Total Radiated Power of one UltraWideBand (UWB) device to support EU RF spectrum regulation
UWB commonly refers to a signal or system that either has a large relative bandwidth (BW) that exceeds 20% or a large absolute bandwidth of more than 500 MHz. Because of such large radio frequency spectrum occupancy, spectrum regulations have to be carefully defined to avoid the risk of interference with other wireless services coexisting in the same bands.
The next update cycle of the UWB regulation in the European Union will be started based on the SRDoc (TR 103 750) from ETSI asking for a band extension of some applications (mainly location tracking and sensor applications) up to 10.6 GHz. The focus of the new investigations in SE24 will be the band 8.5 GHz to 10.6 GHz using a set of mitigation techniques and mechanisms to protect the incumbent services in the band.
One of the mitigation factors to be considered is the total radiated power spectral density TRPSD. The TRPSD parameter is not new in the UWB regulation and has been used in the sensor regulation of UWB since several years. Nevertheless, systematic measurements of the value using typical UWB devices for other application have never been performed. In order to be able to use realistic values in the CEPT, a study was conducted in the JRC on UWB devices to support a realistic evaluation of the interference effects of UWB into other systems and services.
