摘要: In this paper the coverage and capacity of SigFox, LoRa, GPRS, NB-IoT is compared using a real site deployment covering 8000 km2 in Northern Denmark. Using existing Telenor cellular grid it shown that four technologies have more than 99 % outdoor coverage, while GPRS challenged for indoor coverage. Furthermore, study analyzes assuming traffic growth from 1 to 10 IoT device per user. The conclusion 95 %-tile uplink failure rate users below 5 all technologies. For only provides downlink connectivity with less rate, SigFox able provide an unacknowledged data service about 12 rate. Both LoRa struggle sufficient capacity.
