LoRa-Powered IoT Messaging System for Internet-Free Communication

Abstract

Abstract: This paper describes a novel message system that makes use of LoRa technology and the ESP32 IoT chip to deliver dependable communication in places with spotty internet access. The ESP32 module is integrated into the system architecture as an access point, and WebSocket protocol is used to enable messaging services. As a key center for communication, the ESP32- based access point facilitates flawless message exchanges between users. The key innovation lies in its incorporation of the LoRa RA-02 module, which enables RF-based communication among devices. The messaging system guarantees connectivity even in remote locations or areas with inadequate internet infrastructure by utilizing LoRa technology. This capability is especially helpful in situations when regular internet connectivity is unavailable or inconsistent, including in low-resource contexts, rural populations, or areas affected by disasters. Because of the messaging system's easy-to-use and accessible architecture, users can communicate without an internet connection. This lessens the need for internet connections and lowers related expenses, improving communication accessibility and affordability for marginalized communities.
