  1. 16. Beamformed Channel Matrix Positioning using 5G Testbench CSI data with a Deep-Learning Pipeline

    University essay from Lunds universitet/Institutionen för elektro- och informationsteknik

    Author : Andre Ráth; [2022]
    Keywords : 5G; Deep Learning; Positioning; Channel State Information; CSI; Deep-learning; neural-network; particle-filter; particle; filter; Channel Matrix; Beamformed Channel Matrix; localization; real-world; data-driven; 5G testbench; basestation; Technology and Engineering;

    Abstract : 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.

  3. 17. Simulation of Radio Propagation Path in Indoor Environment

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Minu Revathikumar; [2022]
    Keywords : Indoor 3D propagation model; millimeter waves mmWaves ; 5G; Basic propagation mechanism; Excess loss; Inomhus 3Dspridnings modell; millimeter vågor mmVågor ; 5G; Grundläggande spridnings mekanism; Överskotts förlust;

    Abstract : Several propagation channel models are designed to verify signal behavior in specific environments for future 5G cellular networks. Hence, with the massive development and demand of indoor wireless systems, a suitable design prior to deployment is required for energy and cost-efficient implementations. READ MORE

  4. 18. Analysis of radio surveillance in search of missing persons - An empirical study of Bluetooth Low Energy and Wi-Fi characteristics

    University essay from Linköpings universitet/Kommunikations- och transportsystem; Linköpings universitet/Tekniska fakulteten

    Author : Mikael Fredriksson; [2022]
    Keywords : Search and rescue; Wi-Fi; Bluetooth Low Energy; Wi-Fi probes; Bluetooth Low Energy advertisements; wireless sniffing; smartphones; antenna directivity;

    Abstract : Development of technical and methodological support has been identified as a key area for future research and development within the search and rescue (SAR) of missing persons in Sweden. Previous studies have demonstrated the feasibility of using Wi-Fi signals to locate a missing person, and also developed hardware and software for SAR systems based around Unmanned Aerial Vehicles (UAV).

  5. 19. 2D Orientation Estimation Using Machine Learning With Multiple 5G Base Stations

    University essay from Linköpings universitet/Reglerteknik; Linköpings universitet/Tekniska fakulteten

    Author : Jianxin Qu; Nikil Johny Kunnappallil; [2022]
    Keywords : ;

    Abstract : 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.

  6. 20. Challenges Within V2X : A cybersecurity risk assessment for V2X use cases

    University essay from Högskolan i Halmstad/Akademin för informationsteknologi

    Author : Adrian Brorsson; [2022]
    Keywords : Automotive cybersecurity; V2X cybersecurity; V2X use cases; ETSI ITS; ETSI TVRA; V2X risk assessment;

    Abstract : Vehicle-to-Everything (V2X) is referred to as the technology enabling communication and data exchange between vehicles and is considered a significant milestone within automotive. By enabling inter-vehicle communication, the vehicles will be more aware of their surroundings—including things outside their current line-of-sight (LOS). READ MORE
