NXP Semiconductors N.V. (today officially announced its secure fine ranging chipset, SR100T – designed to bring precise positioning performance tailored for UWB-enabled mobile devices.

With the SR100T, mobile devices will be able to communicate with connected doors, points of entry, and cars to open them once approaching. Lights, audio speakers, and any other connected device with UWB sensing capability will be able to follow users from one room to another.

The new UWB-based chipset, SR100T, delivers accuracy, even in crowded, multipath signal environments with numerous walls, people, and other obstacles. The technology also uses angle-of-arrival (AoA) technology to accurately indicate the direction of a signal for added precision.

Furthermore, the SR100T expands NXP’s mobile wallet solution to include spatial awareness for new handsfree access applications.

Features

• 6 to 9 GHz; 500 MHz bandwidth per channel
• High accuracy of AoA estimates with dual-Rx for AoA functionality
• Exceptional range accuracy in non-line-of-sight (nLOS): ±10 cm with angle accuracy (LoS): ±3°
• RF security provided through the security extension currently being specified in IEEE 802.15.4z
• Multiple integrated security mechanisms for both the protection of keys and software security
• Unified security architecture with NFC and Secure Element

NXP is a co-founder of the FiRa Consortium, a community of industry experts dedicated to the development and widespread adoption of user experiences based on the secure fine-ranging and positioning capabilities of interoperable UWB technologies.
