429MHz Band Wireless Modem for Public Infrastructure

For remote monitoring of infrastructure facilities. Achieving reliable data transmission with stable communication.

In the public infrastructure industry, it is important to monitor infrastructure facilities such as bridges and dams remotely to grasp the operational status and abnormalities of the equipment in real-time. Particularly, data transmission in harsh environments requires stable communication, as communication interruptions can lead to serious accidents. The 429MHz band specific low-power serial data transmission wireless modem is more resistant to obstacles compared to the 2.4GHz band, ensuring stable communication distances. With a UART interface, it enables easy wireless implementation without specialized knowledge, contributing to cost reduction in wiring work by replacing existing wired systems with wireless ones. 【Use Cases】 - Monitoring various sensors for bridges and tunnels - Remote monitoring of dams and power plants - Monitoring the operational status of water supply and sewage facilities 【Benefits of Implementation】 - Early detection of equipment abnormalities through stable data transmission - Reduction of costs and labor through decreased wiring work - Rapid response through real-time monitoring from remote locations

MU-3-429

Applications/Examples of results

[Applications] Ideal for industrial applications where "reliable communication" is the top priority, such as sensor monitoring within factories, communication with mobile entities (AGVs and cranes), underground facility monitoring, and environmental control in greenhouses. It is useful for bulk data collection in existing factories where wiring work is difficult, as well as for monitoring the status of equipment scattered across various floors of a building. Due to its low voltage and low power consumption design, it is also suitable for integration into battery-operated measuring devices and portable terminals, making it a trusted module that has been chosen in many sites for many years.
