Ultra-Wideband Technology (UWB)

Ultra-wideband is a short-range radio technology (frequency range between 3.1 and 10.6 gigahertz). It is used, for example, to replace cable-based connections between computers and peripheral devices. Wireless transmission of audio or video signals between multimedia devices is also possible. The maximum data rate is 480 megabits per second. The transmission power is usually less than one milliwatt.

Indoor positioning

One area of application is indoor positioning in industrial environments (range up to 20, maximum 35 meters), where UWB is characterized by high accuracy. Position determination is not based on the measurement of signal strengths, but on the measurement of signal propagation times, which depend on the distance between the receiver and the transmitters (tags) on the objects. The combination of the measured values from at least three receivers allows a position to be determined with an accuracy of between ten and 30 centimeters.


Based on NXP’s ultra-wideband technology and the payment expertise of ING, the pilot aims to make peer-to-peer payments more intuitive and seamless.

NXP® has announced a further expansion of its TrimensionTM portfolio with the industry’s first single-chip solution to combine both UWB radar and fine ranging capabilities.
Industrial Trucks

The company opted for a solution consisting of UWB and RFID. Over 400 UWB tags were applied to forklifts in the factory and 60 RFID sensors were integrated at selected points on the factory floor.

NXP announced that NXP’s Secure Ultra-Wideband (UWB) fine-ranging solution, embedded SIM (eSIM) as well as Near Field Communication (NFC) and Secure Element (eSE) unit are deployed in Samsung’s new Galaxy Note20 Ultra1.
Kathrein Solutions

Starting in 2020, a German car manufacturer has opted for the UWB-based localization solution from Kathrein Solutions. The result: Vehicles and parts supply trolleys localized with an accuracy of only a few centimeters. The RTLS solution ensures the localization on three building levels.

The new real-time location system K-RTLS combines high localization accuracy in an industrial environment with unique technical features.
