Japan is a country where forests cover 70% of the land. Although smart forestry using IoT devices is being implemented, but its diffusion is limited due to the poor availability of power sources and the lack of mobile network base stations. Cell phone base stations require licenses and government permits for installation, and the costs of installation, operation, and removal are expensive. Even tower-type mobile base stations installed in the suburbs have a coverage area of only about 10 km, so even though the population coverage rate has already reached over 99%, the area coverage rate is still less than 70% for all carriers. The purpose of this research is to establish a method to extend Internet Protocol (IP) connectivity to non-electrified areas by patrolling autonomous vehicles using Low Power Wide Area (LPWA) communication systems, especially IEEE802.11ah as the core. and standardize new communication methods.
