1. 1. LEO Satellite Connectivity for flying vehicles

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

   Author : Jinxuan Chen; [2023]
   Keywords : LEO satellite network; satellite connectivity strategy; Nash-SAC; flying vehicles; LEO:s satellitnät; Strategi för satellitanslutning; Nash-SAC; flygande fordon;

   Abstract : Compared with the terrestrial network (TN), which can only support limited covered areas, satellite communication (SC) can provide global coverage and high survivability in case of an emergency like an earthquake. Especially low-earth orbit (LEO) satellites, as a promising technology, which is integral to achieving the goal of global seamless coverage and reliable communication, catering to 6G’s communication requirements.

   Abstract : The Internet of Things (IoT) has emerged as a powerful tool for meeting our need to collect information about and interact with our environments. One important aspect of this technology is positioning which imposes requirements on both the energy consumption and the arrangement of the systems. READ MORE

4. 3. LoRa Radio Performance Analysis Based on AVR-RSS2 and RIOT-OS for Indoor IoT Applications

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

   Author : HongShuo Yi; Duosi Dai; [2023]
   Keywords : LoRa; Indoor IoT Internet of Things ; Signal strength; Round-trip time RTT ; Goodput; LoRaWAN device classes; AVR-RSS2; RIOT-OS; LoRa; Inomhus-IoT Internet of Things ; Signalstyrka; Rundresa-tid RTT ; Goodput; LoRaWAN klasser; AVR-RSS2; RIOT-OS;

   Abstract : This thesis is dedicated to measuring the communication performance of LoRa technology in an indoor environment and providing insight into its potential application as an effective Internet of Things (IoT) communication solution in Low Power Wide Area Networks (LPWAN). Through careful experimentation and analysis, we assessed various transmission parameters such as spreading factor (SF), bandwidth (BW), Payload Length (PL), and LoRaWAN classes. READ MORE

5. 4. Reconnaissance Radar Robot

   University essay from Högskolan i Halmstad/Akademin för informationsteknologi

   Author : Filip Solkela; Jasmine Tuvesson; [2023]
   Keywords : ;

   Abstract : Educational tools in the Army can be challenging due to their size and the fact that they are often set up and used outside of traditional classroom settings. This can make it difficult for students to explore and understand the technologies they are learning about fully. READ MORE

6. 5. Antenna Implants and Feasibility of Performance Limitations : AStudy of Radiation Efficiency on Electrically Small Antenna Implants with Finite Conductivity and Size

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