ABSTRACT
This work addresses the feasibility of extreme long distance links based on LoRa technology. We developed a specialized low-cost and highly sensitive hardware based on the LoRa chipset and deployed it in a 316km long link. Received signal strength, signal to noise ratio, and packet reception rate were measured at two different frequency bands: 434MHz and 868MHz. Results clearly show that the link is feasible at both frequencies even with omni directional antennas. In addition, we provide details on the planning of the experiments, as well as procedure employed to find the suitable test bed for such a long distance link. These types of wireless systems are quite useful for disaster mitigation applications in sparsely populated areas.
