Amazon Web Services (AWS) has added confidence level configuration and measurement type support to its IoT Core for Device Location.

The two enhancements give developers more control over location resolution and richer metadata for resolved device locations.

Those using the cell ID, wifi or cell-plus-wifi 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 such as 95% increases certainty that the device falls within the reported radius but produces a larger accuracy radius. A lower confidence level such as 50% yields a smaller radius with less certainty.

Users can now configure this value to balance accuracy and confidence based on their specific requirements. This feature is supported for HTTP-based location resolution.

The 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, wifi or Bluetooth Low Energy 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.
