[For Smart Meters] 429MHz Band LoRa Compact Wireless Module

Realizing data transmission of smart meters over long distances exceeding 10 km.

In the energy industry, it is essential to collect accurate usage data from smart meters to enable efficient power supply and demand forecasting. Particularly, data collection from smart meters installed in areas away from urban centers or in locations where radio waves are difficult to reach requires stable communication. Our 429MHz band narrowband LoRa small wireless module achieves long-distance communication and low power consumption, streamlining data collection from smart meters. 【Use Cases】 - Installation of smart meters in areas where communication infrastructure is not developed, such as mountainous regions or remote islands - Data collection in places where radio waves are easily obstructed, such as within buildings or underground facilities - Remote monitoring of widely distributed smart meters 【Benefits of Implementation】 - Data collection over a wide area through long-distance communication of over 10 km - Extended battery life due to low power consumption - Easy integration into existing systems via UART interface

Applications/Examples of results

**Applications** Ideal for IoT implementation in **"areas where wireless signals have not reached until now,"** such as monitoring water levels in 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 2.4GHz and 920MHz bands are easily obstructed. With low power consumption and the ability to be battery-operated, it is perfect 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 that covers wide areas.
