1. 1. Evaluating Thread network performance, locating and strengthening weak radio links

   University essay from Linköpings universitet/Fysik, elektroteknik och matematik; Linköpings universitet/Tekniska fakulteten

   Author : André du Rietz; Elias Salo; [2023]
   Keywords : Internet of Things; IoT; Thread network; Evaluating Thread Network;

   Abstract : In the fast-developing world we are living in, a tech phenomenon known as the Internet of Things (IoT) has taken hold. It has seen a lot of development over the past few decades, and today there are an estimated 30 billion IoT devices active. IoT is a machine-to-machine network that senses the world with the help of sensors. READ MORE

3. 2. An evaluation of LoRa transmission parameter selection for indoor positioning

   University essay from Jönköping University/JTH, Avdelningen för datateknik och informatik

   Author : Adina Valjakka; Anton Ahlinder; [2022]
   Keywords : Accuracy; Indoor positioning; LoRa; NLOS; Precision; RSSI; Transmission parameters; Trilateration;

   Abstract : The purpose of this thesis is to investigate how the LoRa modulation configuration affects precision and accuracy when using LoRa for indoor positioning in non-line-of-sight conditions. The aim is to research if an optimum combination of spreading factor, bandwidth, and code rate factor can be found to result in the best possible positioning accuracy and precision, under certain predefined conditions.

4. 3. Telemetry System for Real-Time Monitoring of a Formula Student Electric Vehicle

   University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

   Author : Simon Richter; Joachim Larsson; [2021]
   Keywords : Telemetry; RF; CAN; 868-GHz radio; PCB design;

   Abstract : Real-time monitoring of vehicle data during testingcan drastically cut down on test times as well as improve thequality of testing by facilitating the implementation of run-timecompliance verification with expected model behavior, along withanomaly detection in both hardware and software. By providinga wireless communication link between vehicles and a monitoringbase station, this project aims to build the groundwork formore sophisticated testing proceedings in the future. READ MORE

5. 4. Design of Autonomous Underwater Vehicle’s (AUV) Antenna System

   University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

   Author : Chengzhuang Zhou; [2021]
   Keywords : AUV Antenna; Printed Dipole Antenna; Broadband Antenna; AUV antenna; Printed dipole antenna; Broadband antenna;

   Abstract : The ocean symbolizes mystery, passion, and power. However, most of the ocean, about 80 %, is unknown to humans. AUVs (Autonomous Underwater Vehicles) provide a platform where terrain mapping, the biodiversity, and the resource survey of the ocean become accessible. READ MORE

6. 5. 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. READ MORE
