Study on Balloon Network Using LoRa Mesh Communication System

LoRa wireless communication needs to be installed as high as possible in order to fully demonstrate its communication distance. However, in times of disasters, there are not necessarily high structures that can be conveniently installed. Therefore, in this research, by attaching the LoRa mesh network system developed by NICT to helium balloon and drone, it will make network emergency restoration more realistic in the event of a disaster. We aim to operate 72 h after the occurrence of a disaster, and promote power saving and weight saving.
