AWS IoT Core for Device Location adds Confidence Level Configuration and Measurement Type support

AWS IoT Core for Device Location now supports two enhancements that give developers greater control over location resolution and richer metadata for resolved device locations.

Customers using the Cell ID, Wi-Fi, or Cell+Wi-Fi solvers can now specify a desired confidence level between 50% and 99% when resolving device locations. The confidence level represents the statistical probability that the actual device location falls within the reported accuracy radius. A higher confidence level (for example, 95%) increases certainty that the device falls within the reported radius but produces a larger accuracy radius. A lower confidence level (for example, 50%) yields a smaller radius with less certainty. Customers can now configure this value to balance accuracy and confidence based on their specific requirements. This feature is currently supported for HTTP-based location resolution.

This update also introduces a measurement type field in resolved location metadata, giving developers greater visibility into how each device location was determined — whether through GNSS, Wi-Fi or BLE location resolvers. This make it easier to assess location data quality, debug positioning issues, and make more informed decisions based on how each location was determined.

These updates are available in all AWS IoT Core for Device Location supported regions. For detailed guidance and implementation instructions, visit the AWS IoT Core Device Location and IoT Wireless Developer Guide .
