868MHz LoRa MESH Radio Module With Self-Forming Ad Hoc Networking And Long-Range Communication
 

The LoRa MESH Radio Module 868MHz is a high-performance long-range wireless communication module designed for industrial IoT, telemetry, remote monitoring, and distributed sensor networks. Based on the SX1276 LoRa transceiver, the module combines LoRa spread-spectrum technology with an embedded MESH MANET protocol, enabling automatic self-forming and self-healing wireless ad-hoc networks. Unlike conventional wireless modules, users can deploy networked devices without modifying existing protocols or performing secondary firmware development, significantly simplifying large-scale wireless system implementation.

The module supports transparent transmission, API mode, and AT command mode, providing flexible integration options for microcontrollers, embedded systems, and industrial controllers. Advanced features such as forward error correction, frequency hopping, automatic CRC error correction, CAD signal detection, collision avoidance, and multiple handshake confirmations ensure stable and reliable communication even in noisy RF environments. With receiver sensitivity down to -148dBm, transmit power up to +20dBm, and communication distances reaching 1.5km to 2.5km in open environments, this LoRa MESH module is well-suited for long-distance wireless networking applications.
