1. 1. Ultra-wideband location tracking of mobile devices

   University essay from Uppsala universitet/Signaler och system

   Author : Daniel Hietarinta; [2022]
   Keywords : UWB; ultra-wideband; GPS; tracking; locating; wireless communication; low-power; embedded systems; mobile devices; OTG; sensors; sensor fusion; mobile app; Android; dynamic anchors; ranging; C; Python;

   Abstract : Today’s most widely used tracking solutions for consumers involve the Global Positioning System (GPS) which meets most needs when it comes to rough estimation of location. GPS however is limited in accuracy with a horizontal error of around 5 meters and cannot be used in the areas where the satellites cannot provide a strong enough signal e.g. READ MORE

3. 2. Unlicensed and licensed low-power wide area networks : Exploring the candidates for massive IoT

   University essay from KTH/Radio Systems Laboratory (RS Lab)

   Author : Daniel Sjöström; [2017]
   Keywords : LPWA; LPWAN; IoT; massive IoT; NB-IoT; eMTC; EC-GSM-IoT; SigFox; LoRa; LoRaWAN; LoRa Alliance;

   Abstract : In the Internet of things (IoT), many applications will require low-power and low-cost to achieve long lifetime and scale (respectively). These types of applications are referred to as massive IoT, as opposed to critical IoT, which emphasizes ultra-high reliability and availability and low latency. READ MORE
