Vehicle Access Control (UWB, BLE)

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).

Your challenges

  • Ensure interoperability with UEs and correct operation of automotive UWB applications such as keyless vehicle access and start
  • Demanding requirement to generate and analyze very wideband and low power of UWB signals
  • Very accurate (+/- 100ps) Time-of-Flight (ToF) measurements capability to enable the verification and calibration of components
  • Compliance with IEEE 802.15.4z standard and FiRa & CCC certification program
  • Obligation to ensure compliance with regional / local telecommunications authority regulations

Features of Rohde & Schwarz solutions

  • Able to measure ToF and AoA Rx and Tx parameters in conducted and radiated mode in a single instrument
  • Compliant to IEEE 802.15.4a/z specifications and support of FiRa pre-conformance and conformance tests
  • Very convenient pre-conformance and conformance testing for R&D
  • Optimized production with automated and shielded OTA measurements using dedicated UWB PHY test suite
  • Comprehensive suite of solutions from radio communication testers to oscilloscopes, signal generators and analyzers

Benefits of Rohde & Schwarz solutions

  • Consistency by using same test equipment from R&D to large-scale production
  • Complete test portfolio from one hand provides cost and time efficiencies
  • Cost reduction by reuse of CMP200 for both 5G mmW / FR2 and UWB functions
  • Risk reduction by using R&S expert, standards-compliant OTA test solutions to precisely validate ToF and AoA

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
