  1. 1. Learned Multi-Sensor Indoor Positioning of Mobile Devices

    Master-uppsats, Lunds universitet/Matematik LTH

    Författare :Christoffer Kjellson; [2021]
    Nyckelord :Indoor Positioning; Deep Learning; Fingerprinting; RSSI; Machine Learning; Pedestrian Dead Reckoning; Kaggle; Sensor Fusion; SDAE; LSTM; Technology and Engineering; Mathematics and Statistics;

    Sammanfattning : Attenuation of the microwave signal used in the Global Positioning System (GPS) due to interaction with building structures complicates the task of accurate indoor positioning. For this reason, research on alternative approaches is being performed at universities and companies worldwide. LÄS MER

  3. 2. BLE Beacon Based Indoor Positioning System in an Office Building using Machine Learning

    Master-uppsats, Blekinge Tekniska Högskola/Institutionen för datavetenskap

    Författare :Rohan Reddy Tirumalareddy; [2020]
    Nyckelord :Indoor Positioning System; Fingerprinting; Machine Learning; Bluetooth Low Energy;

    Sammanfattning : Context: Indoor positioning systems have become more widespread over the past decade, mainly due to devices such as Bluetooth Low Energy beacons which are low at cost and work effectively. The context of this thesis is to localize and help people navigate to the office equipment, meeting rooms, etc. LÄS MER

  4. 3. Multi-Factor Mobile based Access Control Solution

    Master-uppsats, Lunds universitet/Institutionen för elektro- och informationsteknik

    Författare :August Larsson; Alvin Ohlsson; [2020]
    Nyckelord :Indoor positioning Wi-Fi Fingerprinting Magnetic Fingerprinting; Technology and Engineering;

    Sammanfattning : In this thesis, alternatives for replacing an RFID card + PIN based access controlsolution for office buildings with a mobile applications are evaluated. The proposedsolutions are based on a probabilistic fingerprinting approach where distributionsof RSSI are approximated and stored in a fingerprint database during an initialoffline phase. LÄS MER

  5. 4. A Cost-Efficient Bluetooth Low Energy Based Indoor Positioning System for IoT Applications

    Master-uppsats, Linköpings universitet/Institutionen för datavetenskap

    Författare :Sanjana Vupparige Vijaykumar; [2019]
    Nyckelord :Indoor positioning system; Internet of Things; Bluetooth Low Energy technology; RSSI; fingerprinting; multilateration.;

    Sammanfattning : The indoor positioning system is a series of networking systems used to monitor/locate objects at indoor area as opposed that of GPS which does the same at outdoor. The increase in the popularity of the Internet of Things made the demand for Bluetooth Low Energy technology more and more essential due to their compatibility in the smartphones which makes it to access easier.

  7. 5. Inomhuspositionering med bredbandig radio

    Kandidat-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Oscar Gustavsson; Adam Miksits; [2019]
    Nyckelord :Indoor Localisation; WiFi-fingerprinting; k-Nearest Neighbour; RSSI; CSI;

    Sammanfattning : In this report it is evaluated whether a higher dimensional fingerprint vector increases accuracy of an algorithm for indoor localisation. Many solutions use a Received Signal Strength Indicator (RSSI) to estimate a position. It was studied if the use of the Channel State Information (CSI), i.e. LÄS MER
