  1. 16. 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
