Rohde & Schwarz has joined the FiRa Consortium as an associate member. FiRa, short for "fine ranging", is an organization dedicated to growing the ultra-wideband (UWB) ecosystem by ensuring interoperability between multiple devices through compliance and certification programs. The FiRa Consortium focuses on three core UWB services: hands-free access control, location based services, and device-to-device services. These rely on the latest UWB-based secure ranging technology specified by the IEEE 802.15.4z.
The advantages of the UWB standard include centimeter-accurate location measurements, allowing for doors to open when approached with a UWB device or bringing positioning functionality to indoor environments. UWB also features secure device-to-device data communications with very low power requirements. The very wide bandwidth and very low power density make it easy for UWB signals to share spectrum with other narrowband and wideband systems without causing interference.
The R&S CMP200 radio communication tester from Rohde & Schwarz, for instance, is ideal for solving UWB challenges in production as well as in R&D. It combines the capabilities of a signal analyzer and generator in a single instrument. In combination with the Rohde & Schwarz WMT software service to implement automated wireless manufacturing testing and a wide portfolio of shielded chambers, the R&S CMP200 offers a complete solution for transmitter, receiver, ToF and AoA measurements in conducted and radiated mode, compliant to IEEE 802.15.4a/z specifications. The R&S SMM100A is a midrange vector signal generator covering up to 44 GHz, and the only in its class to offer a maximum RF modulation bandwidth of 1 GHz, thus meeting the requirements to generate broadband signals used by UWB devices in R&D and production.
