Abstract: Long-range (LoRa) nodes, which work in the sub-GHz frequency bands, are used in IoT applications and in vehicular environments. Deployment of these low-power long-range sensor nodes requires better analysis of the link quality and weather and environmental conditions. In literature very little information is available about the impact of weather conditions on the performance of LoRa-based applications. The impact of the height and the shaded region will also impact the link quality. The suburban and urban environment is considered in this paper to evaluate the performance of the several link qualities under the weather conditions such as fog, humidity, temperature, shaded region and the impact of height. Regular pattern of RSSI is analysed and PDR values are presented to understand the impact of the weather conditions and other effects on the link quality. Real outdoor test bed experimentation was performed to validate the results. We have observed that increase in temperature degrades the RSSI value which further lowers the PDR. These two parameters can be improved by increasing SF value. Humidity and height of node also affect the RSSI value. The given work can help in outdoor LoRa node deployment for various modes of vehicular communications.
