Link Labs has launched AirFinder OnSite, an Internet of Things (IoT) asset tracking platform for campus-based environments. This enterprise Real-Time Location System (RTLS) provides sub-meter accuracy by using a Bluetooth Low Energy (Bluetooth LE) radio to support both Bluetooth LE and phase ranging.
It is suitable for IoT tracking in distribution centers and warehouses. It’s also suitable for various IoT applications in manufacturing, healthcare and supply chain and logistics management, among others.
The solution features at the firmware level cover an array of technical challenges that need to be met for an enterprise grade solution—including ranging methodology, interference avoidance, location algorithm, power efficiency and scalability to high tag densities. Together, these capabilities allow asset location to be fine-tuned to the sub-meter level.
Its phase-ranging and location determination process take place on Nordic Semiconductor’s nRF52833, requiring less than 1/20th of a second. This allows use cases with very low latency requirements to be met, such as forklift tracking or fast alerting when assets leave an internally geofenced area.
