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
