Design and Performance Analysis of IoT Based Sensor System Using LoRa,e of sight conditions. Specifically, the received signal strength indicator (RSSI) and signal to noise ratio (SNR) are studied for different distances between the sensor and gateway nodes. The results showed that RSSI of −117 dBm and SNR of −17 dB can be achieved for a distance of 300 m in non-line
