Applications/Examples of results
**Applications** Ideal for IoT implementation in **"areas where wireless signals have not reached until now,"** such as water level monitoring of rivers and dams, data transmission from inside manholes, environmental management of greenhouses, and infrastructure diagnostics. It is particularly effective for data collection from buildings, mountainous areas, and underground facilities where signals in the 2.4GHz and 920MHz bands are easily obstructed. With low power consumption and the capability for battery operation, it is optimal for telemetry in fields where long-term maintenance is difficult, as well as serving as the core of smart agriculture and disaster prevention monitoring infrastructure covering wide areas.
