NXP Introduces UWB Fine Ranging Chipset for Mobile Device Deployment

By Ken Briodagh

In a recent release, NXP Semiconductors officially announced its secure fine ranging chipset, SR100T, which is designed to bring precise positioning performance for UWB-enabled mobile devices. The company said that mobile devices will be able to communicate with connected doors, points of entry, and cars, while lights, audio speakers, and other connected devices will be able to follow users from one room to another.

The new chipset is designed to amplify and build on NXP’s connectivity, mobile ecosystem, and security architecture found in many of today’s popular mobile payment-enabled devices featuring NFC and SE hardware. The technology reportedly also uses angle-of-arrival (AoA) technology to accurately indicate the direction of a signal for added precision.

“UWB technology is one of the most highly anticipated developments in connectivity and NXP is the first out of the gate to bring seamless, interoperable experiences with an all-in-one solution for mobile devices,” said Rafael Sotomayor, SVP, Mobile, NXP. “Today, NXP’s mobile solutions already impact millions of consumers around the world. The SR100T is an evolution of our secure connected offerings and is designed to complement existing standards like Bluetooth and Wi-Fi. This is a major step forward in allowing developers to deliver ubiquitous UWB experiences to people around the globe.”
