Rohde & Schwarz and Decawave Develop T&M Capabilities for Ultra Wideband Technologies
February 24, 2020
With this solution, both companies address manufacturers planning wireless devices using Ultra Wideband (UWB) technology to provide secure location-based services.
Rohde & Schwarz and Decawave have jointly developed test and measurement capabilities for production line testing of UWB functions in chipsets and complete devices. As part of the cooperation, Decawave provided knowledge of the required test strategy and test methods, as well as the Decawave DW3000 as test device. Rohde & Schwarz has added UWB test capabilities to their R&S CMP200 radio communication tester, making it able to provide R&D and production RF tests for both 5G FR2 and UWB functions.
UWB technology, based on the IEEE 802.15.4a and 802.15.4z standards, enables centimeter-accurate location measurements at distances up to 75 meters. UWB also includes secure data communication at rates up to 27 Mbps, with low power requirements. UWB is an ideal candidate for implementing low latency, highly accurate, reliable, and secure local area location services. UWB opens new doors in the fields of mobile communication, automotive, IoT, and industry 4.0 applications. The wide bandwidth and low power density make it possible for UWB signals to share spectrum with other narrowband and wideband systems without causing interference.
The 802.15.4a/z standards include several frequency bands, Decawave as a founding member of the UWB Alliance already supply products, using frequencies from 3.5 to 6.5 GHz. However, interest is now concentrating on the high band, with channels defined between 5.8 and 10.6 GHz, supporting higher power transmission, leading to longer range. The DW3000 chipset shall operate using UWB channels 5 and 9 in the high band, with a bandwidth of 500 MHz.
The R&S CMP200 radio communication tester is designed to meet RF test requirements for devices operating from 6 to 20 GHz in stand-alone mode, and for all essential 5G FR2 bands including 28 GHz and 39 GHz when used with the remote radio head, the R&S CMPHEAD30. This solution from Rohde & Schwarz is the only test instrument available with the necessary specification to support R&D and production test for UWB and 5G FR2 technologies in a single device.
