  1. 1. Machine Learning-based MIMO Indoor Positioning

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

    Författare :Qiyi Chen; [2023]
    Nyckelord :Technology and Engineering;

    Sammanfattning : The most widely used positioning system is Global Navigation Satellite System (GNSS), which uses traditional positioning techniques and cannot achieve satisfactory positioning performance in indoor scenarios due to Non-Line-of-Sight (NLoS) transmission. Fingerprinting is a non-traditional positioning technique that is robust to NLoS transmission in indoor scenarios. 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. Fingerprinting methods for positioning: A study on the adaptive enhanced cell identity method

    Master-uppsats, Linköpings universitet/Kommunikations- och transportsystem; Linköpings universitet/Tekniska fakulteten

    Författare :Ivan Postigo; [2018]
    Nyckelord :Fingerprinting; Positioning; AECID.;

    Sammanfattning : Fingerprinting methods for positioning is an area of great interest, this thesis presents a study on the Adaptive Enhanced Cell Identity (AECID) fingerprinting method for positioning. By creating a map of the radio characteristics in a geographical region, the AECID method is able to locate a UE by gathering information of the radio conditions of its current location. LÄS MER

  7. 5. Positional Quality of Service using Dynamic Collection Fingerprinting

    Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Datavetenskap

    Författare :Fredrik Grönlund; [2017]
    Nyckelord :quality of positioning; mining; wi-fi; wifi; fingerprinting; positioning; tunnel; underground;

    Sammanfattning : Positioning in environments where GPS is absent is a field currently under intensive research.Systems are currently being researched or designed for indoor use, often relying on ultra-wideband radio, ultrasound, fingerprinting or Wi-Fi.For underground mining, the problem is magnified, as installation of new equipment is expensive.
