    Abstract : Indoor Positioning System (IPS) are becoming more common in many areas such as retail, warehouses, smart facilities, and manufacturing.In recent years, Bluetooth Low Energy (BLE)-based IPS has become increasingly popular due to its low cost and low energy consumption. One of the more recent updates, Bluetooth 5. READ MORE

  3. 2. Hybrid Wireless Positioning

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

    Author : Phalguni Nagendra; Marco Vihelmo Velapatino Gamarra; [2022]
    Keywords : Technology and Engineering;

    Abstract : Numerous location-based services (LBS) have evolved because of the fast development of mobile Internet for use in commerce, entertainment, security, and other areas. All of these need a precise real-time location-based service with smooth indoor- outdoor transition in highly populated areas. READ MORE

    Keywords : aoa; aod; bluetooth 5.1; antenna; array; direction; finding; estimation; MUSIC; subspace; aoa; aod; bluetooth; antenn; antennmatris; riktningsestimation; riktningsidentifiering; MUSIC;

    Abstract : The new Bluetooth standard (Bluetooth 5.1) contains direction finding specifications. Specifications for received signal strength indicator(RSSI) using measures of signal strength in order to give a sense of how far away an object is has been present in earlier versions. READ MORE

  5. 4. Evaluation of Bluetooth 5.1 as an Indoor Positioning System

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : Philip Andersson; Linus Persson; [2020]
    Keywords : Indoor Positioning System; AoA; RSSI; IMU; Sensor Fusion; Multipath Propagation; Inomhus positioneringssystem; AoA; RSSI; IMU; Sensor Fusion; Flervägsutbredning;

    Abstract : There is a high demand for Indoor Positioning Systems (IPS) due to the wide application possibilities. The main issue for localization by wireless signals in an indoor environment is the multipath propagation problem. Multipath propagation occurs when signals reflects and refract from an object, changing the signals characteristics. READ MORE

  6. 5. Design of a Size Reduced Antenna Array for Angle of Arrival (AoA) Estimation for BLE 5.1

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

    Author : Felix Långberg; Jonas Thurborg; [2020]
    Keywords : Antenna; Array; Bluetooth; 5.1; Angle of arrival; optimization; Technology and Engineering;

    Abstract : Bluetooth low energy (BLE) 5.1 allows for Angle of Arrival(AoA) measurements which in turn requires antenna arrays to be used. These arrays must be low power which results in that an efficient switching pattern is applied and for greater field of view good omnidirectivity is necessary. READ MORE
