Experimental Results of LoRa Network Radio Propagation Modeling in Campus Area

LoRa, a low-power technology with a large coverage area, is the IoT communication system that is now utilized most frequently. Several studies have examined the effectiveness of LoRa networks. RSSI, SNR, and PRR are the parameters that were examined. Other researchers studied radio propagation models in addition to demonstrating the performance of the LoRa network. Predicting path loss data that will subsequently be used for designing and optimizing LoRa networks requires accurate radio propagation modeling. This paper proposes a new propagation model for LoRa networks in campus areas using the log distance path loss model. The LoRa network uses point-to-point communication with the LoRa Antares Development Board with a frequency of 915 MHz. This research produces exponential path loss values in indoor and outdoor environments in both LOS and NLOS scenarios. The path loss exponent values for outdoor LOS, outdoor NLOS, indoor LOS, and indoor NLOS are 2.237, 2.486, 1.37, and 2.316, respectively.
