End-to-end positioning system enables accurate and more power-efficient asset tracking

onsemi has released an end-to-end positioning system that allows the simpler and faster development of more accurate, cost- and power-efficient asset tracking solutions. The system is based on the company's RSL15 MCU, the industry's lowest power Bluetooth 5.2 MCU, and includes software algorithms and components supplied by Unikie and CoreHW, producing a fully integrated solution with components optimised to work together.

The new Bluetooth LE solution allows tags to be employed for tracking objects or persons with sub-metre accuracy in defined closed spaces such as warehouses, stores or other buildings. It is scalable to large volumes of tracked objects in terms of performance and cost while lowering the amount of development effort and time-to-market.

With several new advanced features, the device is excellent for various industrial automation applications, including asset tracking, smart retail and IoT edge nodes.

The MCU supports longer range, higher data transmissions and localisation through AoA and AoD.

The company's innovative smart sensing feature permits the Arm Cortex-M33 processor to remain in deep sleep while continuing to monitor sensor interfaces.

The device is designed with Arm TrustZone and Arm CryptoCell-312 technology to establish a device's root of trust and to protect code and data authenticity, integrity and confidentiality. PSA Level 1 certified, this design improves the security measures already provided in the Bluetooth protocol for assurance at the data and application levels.
