Problem addressed

Lack of highly scalable and cost effective indoor and outdoor map service for HK industry. Typical mapping tools are weak at indoor capability and are not optimized for users’ requirements. Massive real time telemetry spatial IoT data is not visualized geographically over a scalable system. BLE device management is insecure, costly and power consuming in large area.

  • Map Server is used to manage telemetry spatial IoT data and serves image map request for interactive map application.
  • Distributed cache is used to improve overall cache hit rate and offload large amount of data traffic from the centralized Map Server
  • Route server combines corridors across multiple buildings and outdoor pedestrian paths to provide shortest navigation route
  • Smart positioning algorithm design can help the user to navigate between different locations (both indoor and outdoor)
  • BLE Broadcast Network is used for large scale BLE device deployment in a secure, cost effective, and power efficient manner
Key impact
  • Enhance the operating performance of map service
  • Connect massive telemetry spatial data with a scalable GIS
  • Enhance the pedestrian navigation experience
  • Protect broadcasted data from unauthorized access
  • Indoor location/navigation application
  • BLE IoT data collection
  • BLE device management
  • Smart city application
