The Vinnova (Sweden’s public innovation agency) funded project SImulation and VErification of wiReless Technologies (SIVERT), with the project participants Volvo Cars, Lund University, Volvo Group, RanLOS and RISE, is now finished. The project was a part of the venture Electronic, software and communication – FFI.
The project has addressed verification of vehicle connectivity modules in a comprehensive way, from simulations in the early phases of a vehicle project to the final verification of implemented systems in complete vehicles. A simulation tool has been developed for direct communication between vehicles, test methods for evaluating the performance of multiple antenna units (MIMO) have been extensively investigated and field test scenarios have been delivered.
For RanLOS the three-and-a-half-year long project has been a great success, and has resulted in that we now can offer commercial wireless communication tests for full-scale vehicles. The project has also resulted in two journal papers and three conference papers (find our publications list here), covering the RanLOS measurement system. Among other results, radiation pattern measurements have been performed, showing good agreement between RanLOS measurement system and a near-field to far-field (NF/FF) antenna measurement range. Also, repeatability measurements were performed, which showed several cases of ideal or close to ideal performance for the RanLOS measurement system.
The work packages in the SIVERT project are focusing on doing system simulations, developing a test setup for component testing with channel emulation, and investigating four different system verification methods on complete vehicle in lab. RanLOS with its measurement system will be part of the latter work package, where the system will be compared to an OTA multi-probe ring setup, a “wireless cable” setup and a reverberation chamber.
