Coverage and Capacity Analysis of Sigfox, LoRa, GPRS, and NB-IoT [PDF]
2017 IEEE 85th Vehicular Technology Conference (VTC Spring), 2017 In this paper the coverage and capacity of SigFox, LoRa, GPRS, and NB-IoT is compared using a real site deployment covering 8000 km2 in Northern Denmark. Using the existing Telenor cellular site grid it is shown that the four technologies have more than 99 % outdoor coverage, while GPRS is challenged for indoor coverage. Furthermore, the study analyzes
