On September 17, 2019, NXP Semiconductors N.V. officially launched the SR100T, a secure precision ranging chipset that provides tailored, high-precision positioning performance for the next generation of UWB-enabled mobile devices. With the SR100T, mobile terminals will be able to communicate with smart doors, entrances and cars. Smart luminaires, smart speakers and any other connected device with UWB sensing capabilities can sense the movement of users in different rooms, and smart connected technologies can be intuitively integrated into people's lives.

NXP's expertise in connectivity and mobile ecosystems and proven security architectures are already widely used in many popular mobile devices with NFC and SE hardware, and the new chipset SR100T with UWB technology is based on this a further breakthrough. The new UWB feature brings new relative positioning connectivity to a wide range of indoor and outdoor devices with virtually no interference. In addition, UWB technology delivers outstanding accuracy even in crowded, multi-channel signal environments where walls, people and other obstacles are numerous. End users can experience the functionality and connectivity that the solution provides without having to remove the mobile device from their pocket. The technology also features Angle Positioning (AoA) technology, which accurately indicates the direction of the signal and further improves accuracy.

In addition, the SR100T extends the NXP mobile wallet solution to provide spatial awareness for new non-inductive access applications.

Rafael Sotomayor, senior vice president of NXP's mobile business, said: "UWB technology is the most anticipated development in the connection field, and NXP is the first to bring a seamless, interoperable experience through a mobile terminal integration solution. Today, NXP Mobile's mobile solutions have benefited millions of consumers around the world. The SR100T is a major advancement in our secure Internet products that complement existing standards such as Bluetooth and Wi-Fi. This step greatly helps developers worldwide. Users provide a ubiquitous UWB experience."

SR100T product performance is the industry standard for robust wireless accuracy and positioning:
6 to 9 GHz;
500 MHz bandwidth per channel;
High accuracy estimation of AoA based on double Rx;
Excellent range accuracy in non-line of sight (nLOS): ±10 cm, angular accuracy (LoS): ±3°.

Multi-layer security method:
Provides excellent RF security through the security extensions currently specified in IEEE 802.15.4z;
Multiple integrated security mechanisms to protect both key and software security;
A unified security architecture with NFC and secure components.
