1. 21. Design of Cellular and GNSS Antenna for IoT Edge Device

   University essay from Högskolan i Halmstad/Akademin för informationsteknologi

   Author : Ioannis Broumas; [2019]
   Keywords : IoT; Internet of Things; Edge device; LTE; 4G; LTE-M1; Antenna; Antenna System; Narrow Band IoT; NB-IoT; Plannar Antennas; GPS; PCB; multiband antenna;

   Abstract : Antennas are one of the most sensitive elements in any wireless communication equipment. Designing small-profile, multiband and wideband internal antennas with a simple structure has become a necessary challenge. READ MORE

3. 22. Using BLE mesh network for indoor tracking

   University essay from Malmö universitet/Fakulteten för teknik och samhälle (TS)

   Author : Ali Hassan; Anna Ahlquist; [2019]

4. 23. Non-Coherent Radio-Based Positioning

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

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

   Abstract : 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. READ MORE

5. 24. Positioning and parking analysis for an indoor positioning system : A comparative study between Bluetooth Low Energy and Ultra Wideband technology

   University essay from KTH/Hälsoinformatik och logistik

   Author : August Brodin Kont; [2019]
   Keywords : radio technology; real-time-localization-service; indoor positioning system; Bluetooth Low Energy; Ultra Wideband; accuracy; precision; sensepoint; radioteknologi; realtidslokaliseringstjänst; inomhuspositioneringssystem; Bluetooth Low Energy; Ultra Wideband; noggrannhet; precision; sensepoint;

   Abstract : The work done in this report as requested by H&D Wireless is performed by using an already developed real time positioning system called Griffin Enterprise Positioning Service and integratingit with ultrasound sensors for presence detection in order to enable assets to park in a visualized environment being actualized by tagging the asset with radio technology hardware. The testing environment was deployed with radio technology hardware equipped for transmitting and receiving radio signals for position estimation of tagged objects where hardware tags emits radio signals being received by sensing radio technology chips called sensepoints which also serves as communication links for further data processing.
