1. 16. GPS-Tracking Device with Long Range and Bluetooth Low Energy Communication

   University essay from Linköpings universitet/Elektroniska Kretsar och System

   Author : Rasmus Oliv; [2019]
   Keywords : GPS; LoRa; BLE;

   Abstract : The thesis is about the construction of a GPS-tracker that can read NFC (Near Field Communication)-tags and communicate with LoRa (Long Range) and BLE (Bluetooth low energy) and investigate which of the components in the GPS-tracker that consumes most power. The usage area for the GPS-tracker is to make the work on disaster affected sites more efficient and secure by having an operation leader that can organizing the operation with help of the information provided by the GPS-trackers that are placed on the injured people and recuing personnel.

3. 17. 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

4. 18. Integration and evaluation of LoRa sensors in GreenIoT

   University essay from Uppsala universitet/Institutionen för informationsteknologi

   Author : Giovanni Santini; [2019]
   Keywords : ;

   Abstract : The Internet of Things, usually shortened as IoT, grows every day bigger, covering more aspects of our daily life. Small devices are capable of transmitting data that allow better feedback from common services such as healthcare, urban traffic coordination, resources management as water, electricity and waste and so on.

5. 19. Towards Long-Range Backscatter Communication with Tunnel Diode Reflection Amplifiers

   University essay from Uppsala universitet/Fasta tillståndets elektronik

   Author : Gustav Eriksson; [2018]
   Keywords : Amplified backscatter tag; Reflection amplifier; Battery-free; Long-range communication; Tunnel diode; Ultra-low power consumption; RFID; Frequency shift;

   Abstract : Backscatter communication enables wireless communication at a power consumption orders of magnitude lower than conventional wireless communication. Instead of generating new RF-signals backscatter communication leverages ambient signals, such as WiFi-, Bluetooth- or TV-signals, and reflects them by changing the impedance of the antenna.
