Abstract
Understanding the limitations of the long-range (LoRa) network to similar communication technologies providing greater insight into how these constraints might affect implementations and strategies that use a LoRa network. This paper is supported by several testing for the analysis in two different areas that verifies the signal strength of a LoRa network. LoRa network will get affected by physical and environmental attributes such as height, distance, and crowded level of surrounding by measuring the Received Signal Strength Index (RSSI), Signal to Noise Ratio (SNR), and Packet Reception Rate (PRR). The signal strength of LoRa in the straight road from 0m until the signal is breakdown also discussed. The experiments are conducted by using two RFM95W LoRa transceivers as the gateway and receiver, at UTeM Kampus Induk environments. The findings are that the LoRa network is suitable for small-scale projects with low gateway elevation and a large distance communication range. This is because the obstruction of the signal makes the message is broken and unusable levels at around 150m in a residential area and 300m in an open space. In conclusion, to make the line of sight free by elevation the LoRa hardware has to increase the PRR and reduce the noise.
