6. Beamformed Channel Matrix Positioning using 5G Testbench CSI data with a Deep-Learning Pipeline
University essay from Lunds universitet/Institutionen för elektro- och informationsteknikAbstract : Within the telecommunications industry, a positioning system for estimating user equipment (UE) location using purely information available for the basestation has an enormous number of potential uses. The link between physical position and the network channel state enables potential positioning systems to function by under- standing the network channel state dependency on location, using a model-based, data-based, or a combined approach.

9. 2D Orientation Estimation Using Machine Learning With Multiple 5G Base Stations
University essay from Linköpings universitet/Reglerteknik; Linköpings universitet/Tekniska fakultetenAbstract : Localization of mobile devices has implications on a multitude of use cases such as estimating the location of the user originating an emergency call, localization of devices to enable autonomous operation required by industrial Internet of Things (IoT) use cases, etc. In futuristic use cases such as Augmented Reality (AR), Virtual Reality (VR), Extended Reality (XR), autonomous navigation of Unmanned Aerial Vehicles (UAVs), we will require the capability of estimating orientation in addition to position of such devices for efficient and effective provisioning of these services to the end-users.

10. An evaluation of LoRa transmission parameter selection for indoor positioning
University essay from Jönköping University/JTH, Avdelningen för datateknik och informatikAbstract : The purpose of this thesis is to investigate how the LoRa modulation configuration affects precision and accuracy when using LoRa for indoor positioning in non-line-of-sight conditions. The aim is to research if an optimum combination of spreading factor, bandwidth, and code rate factor can be found to result in the best possible positioning accuracy and precision, under certain predefined conditions.
