To identify the capability of the LoRa wireless communication and coverage predic-
tion, a CloudRF
®
simulator was used. CloudRF
®
is an online radio planning tool that can
perform link budget and coverage prediction by considering the surrounding effect.
CloudRF
®
also offers configurable options to simulate the conditions and characteristics
