In disaster-prone regions, effective communication is vital to ensuring public safety and
addressing the needs of affected communities, especially in areas where traditional
infrastructure is damaged. The Development of an Off-Grid Communication System Using
LoRa Mesh Wireless Network aims to provide a reliable, cost-effective communication

solution for post-disaster scenarios. The prototype utilizes a LoRa module to enable long-
range, low-power communication through a mesh network, complemented by a

microcontroller for battery monitoring, LED indicators, and an external buzzer for message
notifications. A 12V rechargeable battery pack ensures continuous operation, while the
LoRa Meshenger app offers a user-friendly interface for sending and receiving messages.
The system was successfully tested across three evacuation centers in Pangasinan,
demonstrating stable communication links and usability in scenarios where conventional
infrastructure is unavailable. Evaluated by 30 personnel, such as Disaster Risk Reduction
& Management officers, Barangay officials, volunteers, and Teachers, resulted in a highly
acceptable mean score of 4.66, highlighting its functionality, reliability, and efficiency.
This project contributes to disaster preparedness by offering a sustainable, off-grid

communication network that supports emergency response efforts in underserved and high-
risk communities.
