Long-Range Emergency Communication Using LoRa Technology for Disaster Management

In this paper, the design and development of a LoRa communication system for disaster management application has been introduced. The proposed system can be used for long-range communication, and it can be used in the situation that the cellular and internet are not available, which is a time to emergency. The system is made up of an ESP32 microcontroller, LoRa module, GPS module, keypad, OLED display, and solar power source, making it a portable, low-power, and inexpensive communication system. Experimental implementation showed that the communication had a high reliability over long distances and low consumption. The proposed system provides a practical and cost-effective solution for emergency communication and has the potential to be applied to different IoT and real-world applications. It is useful for emergency response and management due to its applications in communication, tracking and alerting capabilities.
