1、Optimized with high receiving sensitivity (RSSI) and strong signal‑to‑noise ratio (SNR), with powerful anti‑interference technology. 2、Point‑to‑point mode PC connected with 2 Lora modules point‑to‑point support two‑way data transmission and reception at the same frequency. 3、Address and encryption functions can be enabled, directional communication between modules, safe and reliable, to prevent data leakage. 4、The radio can realize multi‑level relay networking, which is suitable for ultra‑long distance and complex environment networking communication. 5、Strong anti‑interference, transmission distance and penetration ability are several times higher than traditional communication. 6、This function can modify the parameters of the radio remotely, which greatly reduces the cost of installation and debugging and maintenance.
