In recent years, the use of wireless networks that can transmit data over long distances with low energy consumption has increased (e.g., LoRaWAN). Currently, the advantages of the networks cannot yet be fully exploited in location-based services, since the calculation of the location on the end device causes a high energy demand. However, in many use cases, knowledge of the current location on the device is not necessary (e.g., in the area of asset tracking), so the costly computation can be externalized.
The goal of this work is to investigate different methods that allow the GNSS raw data to be forwarded to external systems using low-power radio networks, which compute the current location, and to implement this prototypically if necessary.
