Bosch Selects Rohde & Schwarz to Verify UWB Connectivity

By Joel Davies -

The Bosch Group has selected the R&S CMP200 radio communication tester from Rohde & Schwarz to validate automotive Ultra-Wideband (UWB) applications in manufacturing.

Because of its range, power consumption and security capabilities, ultra-wideband (UWB) is likely to feature on a range of IoT peripherals and industry 4.0 applications in the future and is expected to be a standard technology of most smartphones. In the automotive domain, UWB enables new convenience and functional safety use cases specifically for keyless vehicle access using the smartphone as a digital key. Other potential features include valet parking, occupancy detection and life sign monitoring of babies in child seats.

UWB, based on the IEEE 802.15.4a and 802.15.4z standards, enables centimetre-accurate location measurements at short distances and is most effective up to 70 metres. The technology includes secure data communication at rates up to 27 Mbps, with low power requirements. The wide bandwidth of 500 MHz, combined with a low power spectrum density makes it possible for UWB signals to share spectrum with other technologies without causing interference.

Rohde & Schwarz provides a range of UWB test solutions for R&D, certification, chipset characterisation and production that measure key parameters such as Time of Flight (ToF) and Angle of Arrival (AoA). The firm integrated UWB test capabilities into their R&S CMP200 radio communication tester, making it the only test platform on the market able to provide R&D and production RF tests for both 5G mmWave / FR2 and UWB functions.

The tester combines the capabilities of a signal analyzer and a signal generator in a single instrument. In combination with Rohde & Schwarz shielded chambers and the company’s automatization software WMT, the R&S CMP200 offers a solution for a transmitter, receiver, ToF and AoA measurements in conducted and radiated mode, compliant to IEEE 802.15.4a/z specifications.

“We’re pleased to support Bosch, the leading global supplier of technology in automotive electronics, with our wireless connectivity test solutions. Our R&S CMP200 radio communication tester together with our OTA test chambers are the right choice providing the test coverage and reliability required by the automotive industry. The system can also be used to test 5G connectivity”, said Juergen Meyer, Vice President Automotive at Rohde & Schwarz.
