The Bosch Group has selected the R&S CMP200 radio communication tester from Rohde & Schwarz to validate automotive ultra-wideband (UWB) applications in production. The project is part of the long-term cooperation between Bosch and Rohde & Schwarz in the field of wireless connectivity.

Rohde & Schwarz has added UWB test functions to its R&S CMP200 radio tester.

Thanks to its excellent characteristics in terms of position determination, consumption and transfer security, it is likely that in the future, Ultra-Wideband (UWB) will be included in a wide variety of IoT peripherals and Industry 4.0 applications, as well as on most smartphones as standard technology. In the automotive sector, UWB technology opens up new application possibilities to increase convenience and security, for example for keyless access to the vehicle with the help of a smartphone as a digital key. Other advanced features include valet parking, occupancy detection, and even monitoring vital signs of children in an infant seat.

UWB technology is based on the IEEE 802.15.4a and 802.15.4z standards, and allows position determination with centimeter precision over short distances, especially up to 70 meters. This technology offers secure data communications at speeds of up to 27 Mbps, with very low consumption. Thanks to its wide bandwidth of more than 500 MHz and its low spectral density, UWB signals can share the spectrum with other technologies without causing interference.

It is important to test the performance of UWB devices both in the laboratory and on the production line to ensure regulatory compliance, correct operation, and position determination accuracy. As a leading provider of test and measurement equipment for wireless devices, Rohde & Schwarz provides a complete range of UWB test solutions for research and development, certification, chipset characterization, and production that enable accurate measurement of key parameters such as runtime, flight (ToF) and angle of arrival (AoA). In addition, as a member of the FIRa Consortium and the Car Connectivity Consortium, Rohde & Schwarz supports global inter-professional standards for UWB interoperability.

Rohde & Schwarz has integrated UWB test capabilities into its R&S CMP200 radio tester, making it the only platform on the market capable of providing RF testing for R&D and production, both in the mmWave/ 2G FR5 as in UWB. It is the ideal solution to solve the challenges associated with UWB testing, both in mass production and in R&D. The tester combines the functions of a signal analyzer and a signal generator in a single instrument. In combination with Rohde & Schwarz anechoic chambers and the company's WMT automation software, the R&S CMP200 offers a complete solution for transmitter, receiver, ToF and AoA measurements in conducted or radiated mode in accordance with IEEE 802.15.4a specifications. /z.

“We are pleased to help Bosch, the leading global provider of technology in the automotive electronics sector, with our wireless connectivity test solutions. Our R&S CMP200 radio tester together with our OTA (over the air) anechoic chambers are the perfect solution to provide the test coverage and reliability required by the automotive sector. The system can also be used to test 5G connectivity,” says Jürgen Meyer, Vice President Automotive Market Segment at Rohde & Schwarz.

Markus Hetzel, manufacturing engineer at Bosch, comments: “This cooperation promotes industry standards such as UWB for communications between vehicles and smartphones. It is important to test the performance of UWB devices both in the lab and on the production line to ensure compatibility and correct operation."
