[Solution Introduction] Rohde & Schwarz and Vector jointly demonstrate typical traffic scenario testing
Rohde & Schwarz and Vector demonstrated C-V2X typical traffic scenario testing, which consists of R&S®CMW500 network simulator and R&S®SMBV100B GNSS signal generator hardware and Vectors CANoe.Car2x and DYNA4 (full vehicle and road environment simulation software) C-V2X test components. This flexible C-V2X traffic scenario test solution helps save time and cost in deploying cellular V2X.
For years, automakers and government agencies have been looking for ways to make roads safer and manage traffic flow more efficiently. Wireless communication systems are evolving, and the vision of vehicle-to-vehicle (V2V) and vehicle-to-roadside unit (V2I) communications is becoming a reality. These automotive electronic wireless communication systems planned for vehicle-to-everything (V2X) communications are collectively referred to as Intelligent Transport Systems (ITS). The first solutions were based on IEEE 802.11p technology, but now cellular vehicle-to-everything (C-V2X) solutions based on LTE are emerging, and the industry is already discussing how 5G will play a role.
Well-established vehicle sensors such as radar sensors, cameras and tachometers already provide information about distance, surroundings and speed, but transmitting vehicle information to other systems can also help understand important traffic conditions and collision situations so that the driver or the car can initiate countermeasures to avoid an accident or improve traffic flow.
Vehicle-to-vehicle (V2V) communication systems require a stable wireless link to maximize information throughput and thus improve driver safety. To ensure a good wireless link, the receiver must be able to detect the signal even under the worst conditions, such as low signal-to-noise ratio (SNR), poor error vector magnitude (EVM), and heavy fading. Reproducing these conditions in the lab requires high-performance test equipment that can generate/analyze V2X signals, the required fading conditions, and the satellite signals that enable high-precision positioning.
