  1. 21. UWB-TWR performance comparison in a hybrid node network

    University essay from Luleå tekniska universitet/Institutionen för system- och rymdteknik

    Author : Oskar Sundin; [2021]
    Keywords : UWB; TWR; CSMA; Token ring;

    Abstract : This thesis investigated the performance of a positioning system that utilised UWB technology where devices regularly shifts between acting as an initiator and as a responder for distance measurements between each other. The goal was to investigate existing positional techniques and to implement a novel network where devices initiates and responds to distance measurement exchanges. READ MORE
