The project aims to develop, fine-tune and test a high-precision geolocation system (5-50m depending on the technology) and very low energy consumption, operating both indoors and outdoors. This system targets connected objects (IoT) by reducing the size of their battery and/or extending its lifespan (up to 10 years for certain applications).
The main objectives are:
- To combine information from the different standards supported by an object (LoRa, LTE-M) but also (BLE, Wi-Fi, GPS), as well as from different sensors (barometer, accelerometer) to improve the precision of geolocation (data fusion ) while controlling consumption.
- In addition to the first objective, to improve existing techniques, for example LTE OTDOA (Observed Time Difference Of Arrival).
- To use geolocation information to improve MU-MIMO (Multi-User MIMO) techniques in a 5G perspective.
- To minimize the overall consumption of the infrastructure and the IoT terminal.
