Rohde & Schwarz Joins FiRa Alliance to Accelerate Ultra-Wideband (UWB) Ecosystem

As a device manufacturer with extensive expertise in the field of mobile device testing and certification, Rohde & Schwarz recently announced that it has joined the FiRa Alliance and will contribute to the organization’s establishment of an Ultra-Wideband (UWB) device certification program.

FiRa, short for “Precision Ranging,” is committed to ensuring interoperability among multiple devices through compliance and certification programs to grow the Ultra-Wideband (UWB) ecosystem. The FiRa Alliance focuses on three core UWB services: hands-free access control, location-based services, and device-to-device services, all based on the latest UWB secure ranging technology defined by IEEE 802.15.4z.

The biggest advantage of the UWB standard is the centimeter-accurate position measurement, allowing automatic opening of entrances or the introduction of positioning capabilities into indoor environments when a UWB device approaches. UWB also features secure device-to-device data communication with very low power consumption. The extremely high bandwidth and extremely low power density make it easy for UWB signals to share spectrum with other narrowband and wideband systems without causing interference.

As a leader in wireless device testing, Rohde & Schwarz works with industry partners to develop UWB test solutions for R&D, certification and production, including Time of Flight (ToF) and Angle of Arrival (AoA) measurements as well as device calibration steps etc. Alexander Pabst, Vice President Wireless Communications Marketing at Rohde & Schwarz, said: “We fully recognize the power of secure and reliable UWB technology and are delighted to further strengthen our collaboration with members of the FiRa Alliance to establish a robust certification framework. “

The R&S CMP200 wireless comprehensive tester from Rohde & Schwarz is ideal for helping users meet UWB challenges in production and R&D. Combining the functions of a signal analyzer and signal generator to support automated wireless manufacturing test in combination with Rohde & Schwarz WMT software services, the R&S CMP200 provides transmitter, receiver, ToF and AoA measurements in conducted and radiated modes A complete solution is compliant with the IEEE 802.15.4a/z standard. The R&S SMM100A is a vector signal generator that covers up to 44 GHz and is the only product of its kind that offers a 1 GHz RF modulation bandwidth, so it can meet the requirements of wideband signals used in UWB devices, and is compatible with R&D and different stages of production.
