This paper focuses on the implementation of Meshtastic firmware, showcasing its effectiveness in establishing a decentralized mesh network for communication and location tracking in areas where internet connectivity is unreliable. A thorough analysis of the system's features, including real-time device tracking and secure messaging, highlights its significant potential for military and surveillance applications in remote or off-grid settings. The decentralized mesh framework enhances resilience in dynamic environments, providing a versatile communication solution where conventional infrastructure is lacking or compromised. The experiments successfully demonstrate the real-world application of LoRa communication technology in urban settings, achieving dependable communication between sender and receiver boards over distances of up to 2 kilometers, even in the presence of potential urban interference. Additionally, this research highlights security protocols and ethical considerations relevant to the deployment of Meshtastic firmware in military and surveillance scenarios, offering insightful guidance for future studies and practical implementations.
