Rohde & Schwarz and Samsung have collaborated to verify secure ranging test cases for the ultra-wideband (UWB) PHY layer and assess the secure receiver characteristics of devices based on FiRa specifications. There are new test cases specified in the FiRa 2.0 Technical Specifications, which covers the prevention of physical layer attacks on secure ranging applications based on UWB technology. These test cases were verified with the R&S CMP200 radio communication tester from Rohde & Schwarz on Samsung’s latest UWB chipset.
