  1. 1. Localization of eNodeBs with a Large Set of Measurements from Train Routers

    Master-uppsats, Karlstads universitet/Institutionen för matematik och datavetenskap (from 2013)

    Författare :Simon Sundberg; [2019]
    Nyckelord :Localization; Positioning; LTE; eNodeB; base stations; Received Signal Strength; RSS;

    Sammanfattning : This master thesis investigates the possibility of locating LTE base stations, known as eNodeBs, using signal measurements collected by routers on trains. Four existing algorithms for transmitter localization are adopted: the centroid, strongest signal, Monte Carlo path loss simulation and power difference of arrival (PDoA) methods. LÄS MER

  3. 2. Non-Coherent Radio-Based Positioning

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

    Författare :Farshid Rezaei; Mohamad Abou Nasa; [2019]
    Nyckelord :target localization and tracking; wireless sensor network WSN ; hybrid measurements; received signal strength RSS ; angle of arrival AoA ; Technology and Engineering;

    Sammanfattning : In this thesis, a new Angle-of-Arrival (AoA) technique is used to determine the direction of a target in an outdoor environment using Radio Frequency (RF) signals. This technique estimates the AoA based on the difference between the Received Signal Strength Indicators (RSSI) from two/four directive antennas. LÄS MER

  4. 3. Indoor Positioning Using WLAN

    Uppsats för yrkesexamina på grundnivå, Örebro universitet/Institutionen för naturvetenskap och teknik

    Författare :Pierre Andersson; Arvid Norlander; [2012]
    Nyckelord :Indoor Positioning; WLAN; Fingerprinting; RSS; Signal Strength; RSS Difference; Cell Phone; Mobile Phone; Android; Radio Map; WiFi; 802.11; Wireless; Indoor; Positioning; Localisation; Localization; inomhuspositionering; WLAN; fingeravtryck; RSS; signalstyrka; RSS skillnad; mobiltelefon; Android; radiokarta; WiFi; 802.11; trådlös; inomhus; positionering; lokalisering;

    Sammanfattning : This report evaluates various methods that can be used to position a smartphone running the Android platform, without the use of any special hardware or infrastructure and in conditions where GPS is unavailable or unreliable; such as indoors. Furthermore, it covers the implementation of such a system with the use of a deterministic fingerprinting method that is reasonably device independent, a method which involves measuring a series of reference points, called fingerprints, in an area and using those to locate the user.

  5. 4. Potential of existing UMTS Signaling Data for Cell Phone Positioning

    Master-uppsats, Institutionen för teknik och naturvetenskap

    Författare :Awais Akram; Hamad Ahmad; [2011]
    Nyckelord :Positioning; UMTS; SFN-SFN Observe Time Difference; SFN-SFN OTD; SFN-SFN; RSCP; RSS;

    Sammanfattning : In the current era of telecommunication the usage of cellular network has increased rapidly. Number of different new services are introduced i.e. navigation, friend finder, internet browsing, nearby filling stations, shopping centers, traffic information and emergency services. LÄS MER

  7. 5. Pårørende til personer med demens : Evaluering av en psykoedukativ intervensjon rettet mot pårørende

    Master-uppsats, Nordiska ministerrådet/Nordic School of Public Health NHV

    Författare :Aud Johannessen; [2006]
    Nyckelord :Dementia; Relatives; Intervention; Stress; Demens; pårørende; intervensjon; stress;

    Sammanfattning : Bakgrunn: ”Demens i familien” er en intervensjonsstudie hvor psykoedukativ metode ble benyttet for å redusere stress hos pårørende, og for å redusere psykiatriske tilleggssymptomer hos personer med demens. Studien pågikk i Norge fra 2001-2004. Denne MPH- oppgaven er en delstudie av”Demens i familien”. LÄS MER
