Vehicle Access Control (UWB, BLE)

Ultra-Wideband technology for automotive convenience and security

UWB's accurate ranging, low power consumption, high security and reliability makes it suitable for many automotive applications, particularly keyless vehicle access. In the coming years, almost all smartphones will support UWB and the technology will be widely adopted by vehicle manufacturers to support applications such as indoor navigation, access credential sharing using a Digital Key, handsfree payment and parking assistance. Further in the future, UWB applications could also include in-car child presence detection, health monitoring and gesture recognition. Testing fundamental parameters such as Time-of-Flight (ToF) and Angle-of-Arrival (AoA) is critical to ensure the correct operation of UWB-based functions in modern vehicles.

Rohde & Schwarz offers a complete suite of UWB testing solutions and supports global cross-industry standards for UWB with active membership of FiRa and the Car Connectivity Consortium (CCC).

For handsfree vehicle access control, these wireless technologies are required:

BLE is for data exchange
UWB is for precise ranging
SE (Secure Element) provides the required keys
NFC is used as back-up
