By joining the Car Connectivity Consortium (CCC), Rohde & Schwarz is committed to industry-wide standards for communication between vehicles and smartphones. R&S is contributing its measurement technology expertise in the areas of mobile devices and in-vehicle connectivity.
UWB is a digital radio technology designed for short-range communication, i.e. the spatial and directional transmission of data with very high throughput. It is expected that the technology will be used on numerous computer and IoT peripherals. Performance testing of UWB devices is important in the lab and on the production line to ensure compatibility and reliable operation. R&S has UWB test solutions for R&D, compliance testing and production. This allows important parameters such as time of flight and angle of arrival to be precisely determined. Jürgen Meyer, Vice President Market in the Automotive segment at R&S, comments: "With our membership in the CCC, we want to provide suitable test solutions for the automotive industry so that the connected vehicle can become a reality more quickly. We look forward to working closely with the CCC."
The ability to precisely determine positions, low power consumption and high reliability make UWB suitable for many applications in the automotive sector, such as remote access via virtual keys. Application scenarios include opening the trunk or autonomous parking. In addition, the UWB-supported digital key connection standardized by the CCC can be used to pass on access data for rental vehicles. Cell phones can be used to grant temporary access to the vehicle, for example for delivery services to deposit parcels directly in the vehicle.
The R&S CMP200 Radio Communication Tester offers a solution for UWB measurement requirements in production, research and development. It combines the functions of a signal analyzer and a signal generator. With the WMT software service for implementing automated wireless tests in production and in shielding chambers, the CMP200 is a complete solution for transmitter, receiver, ToF and AoA measurements in wired and wireless mode according to the IEEE 802.15.4a/z specifications.
CCC is a cross-industry organization promoting smartphone and vehicle connectivity technologies. The recently introduced CCC Digital Key Release 3.0 specification enables passive keyless entry and engine start from a compatible mobile device via UWB in conjunction with Bluetooth Low Energy.
