  1. 1. Evaluating LoRa Physical as a Radio Link Technology for use in a Remote-Controlled Electric Switch System for a Network Bridge Radio-Node

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

    Author : Abdullahi Aden Hassan; Rasmus Karlsson Källqvist; [2019]
    Keywords : LoRa; Emergency preparedness; Amateur radio; System design; Embedded system; Radio electronics; LoRa; Krisberedskap; Amatörradio; Systemdesign; Inbyggda system; Radioelektronik;

    Abstract : This report explores the design of a system for remotely switching electronics on and off within a range of at least 15 km, to be used with battery driven radio nodes for outdoor Wi-Fi network bridging. The application of the network bridges are connecting to remote networks, should Internet infrastructure fail during an emergency. READ MORE

    Abstract : With wireless signals, it is possible to send all kind of data through a communication system. Many companies today having problems implementing wireless communication system because of big areas and many obstacles that blocks the wireless signals. READ MORE

  3. 3. A Multi-Target Graph-Constrained HMM Localisation Approach using Sparse Wi-Fi Sensor Data

    University essay from KTH/Optimeringslära och systemteori; KTH/Optimeringslära och systemteori

    Author : Simon Danielsson; Jakob Flygare; [2018]
    Keywords : Hidden Markov Model; Localisation; Wi-Fi Sensors; Forward-Backward Algorithm; Baum-Welch Algorithm; Machine Learning; Time Series Analysis.; Hidden Markov Model; Lokalisering; Wi-Fi Sensorer; Forward-Backward Algoritm; Baum-Welch Algoritm; Maskinlärning; Tidsserieanalys.;

    Abstract : This thesis explored the possibilities of using a Hidden Markov Model approach for multi-target localisation in an urban environment, with observations generated from Wi-Fi sensors. The area is modelled as a network of nodes and arcs, where the arcs represent sidewalks in the area and constitutes the hidden states in the model. READ MORE
