The value of conformance testing for interoperability

Seamless interoperability of UWB devices is of utmost importance for the success of UWB applications such as keyless entry, asset finding, sensing and navigation. It is essential to ensure a safe and effective user experience. The certification program established by the FiRa™ Consortium builds the cornerstone to drive interoperability across the industry.

FiRa™ conformance testing

The FiRa™ certification program is intended to support interoperability of UWB devices which use secure time of flight (ToF) ranging measurements on different layers.

The certification program includes physical layer con formance testing that needs to be executed by FiRa™ authorized test laboratories (ATL) using FiRa™ validated test tools such as the UWB PHY test suite for the R&S®CMP200.

The physical layer requirements and certification test cases are derived from the related HRP UWB standard specified in IEEE802.15.4 clause 15 and complemented by FiRa™. FiRa™ focuses on enhanced ranging devices (ERDEV) supporting both modes: base pulse repetition frequency (BPRF) and high pulse repetition frequency (HPRF) in the high band (band group 2) for 499.2 MHz channels as spec ified in the latest standard amendment IEEE802.15.4z. For conformance testing, a couple of transmitter and receiver test cases were specified aimed at improving interoperabil ity, quality and performance.

Rohde & Schwarz solution

The UWB PHY test suite from Rohde&Schwarz is a PHY conformance test tool (PCTT) that supports conformance testing of the UWB PHY layer as specified by the FiRa™ Consortium. This test platform, validated by the FiRa™ Consortium for physical layer certification, is based on the R&S®CMP200 radio communication tester that sup ports UWB measurements and UWB signal generation via waveform files.

The R&S®CMP200 is connected via an external combiner (included with the R&S®CM-Z300A) to the antenna port of the device under test (DUT). The UWB PHY test suite run ning on an external PC controls the instrument via LAN and communicates with the DUT over a serial interface using the UWB command interface (UCI) protocol speci fied by the FiRa™ Consortium.

The UWB PHY test suite, which is based on the industry proven R&S®WMT test automation framework, allows fully automated execution of the FiRa™ test cases as required by authorized test laboratories for FiRa™ certification. At the end of a test run, the tool provides an overall pass/fail verdict and all details about the performed tests. Finally, it generates a tamper-proof test report containing all relevant information required to apply for FiRa™ certification.

The UWB PHY test suite is especially beneficial for R&D engineers to perform preconformance testing. This solu tion provides the expected flexibility via an easy-to-use graphical user interface (GUI).

With the appropriate R&S®CMP200 options, it is possible to modify the predefined test cases or to create new ones with the help of the integrated test plan editor or to create specific UWB waveforms. The FiRa™ test cases can also be combined with IEEE802.15.4a/z tests, which makes the UWB PHY test suite a universal tool for layer one devel opment. For detailed analysis, the web based GUI of the R&S®CMsquares test software provides deep insight into all test results.
