Real scenario tests were performed and images, at distances up to 2.5 km from node to gateway in urban environment, were transmitted and correctly decoded. The obtained results show the effectiveness of a low-power wide-area (LPWAN) technology prototype for long distance image transmission in applications without delay constraints and where other wireless technologies are not available.engLoRaWANlow rate image transmissionIoT visual sensor nodesmart agricultureconference object2023-04-24cv-prod-324310610.1109/ntic55069.2022.10100422
