France has a strong academic tradition and is committed to investing in research and education. Here's what French academics make.

Conventional localization methods based on low-cost and low-complexity wireless communication standards (e.g., Long Range - IoT Lora or Sigfox systems, WiFi/BT-LE) can provide a positioning accuracy level (respectively, 500m to 1km in outdoor, 5m to 10m in indoor) that is not suitable to the needs of emerging applications, such as geo-referencing of the data produced by mobile IoT sensor nodes, or smartphone-based pedestrian navigation in public areas or office buildings.In the frame of these PhD investigations, we thus propose to rely on Artificial Intelligence on the one hand (typically, on deep learning techniques), as well as on advanced management/representation methods adapted to spatialized data on the other hand, so as to improve localization performance, while relaxing underlying technological specifications (more particularly, in terms of wireless transmission capabilities). The idea is to learn (over both space and time) and to fuse multi-parameter maps, benefitting not only from radio metrics notoriously ill-adapted to localization (e.g., received power, packet error rate...) and contributed in a participatory way by the different mobile agents on the field, but also from other available modalities depending on the application context (e.g., prior road network map/building layout, physical environmental measurements such as ambient sound, embedded inertial units, etc...).
