LoRa QoS Performance Analysis on Various Spreading Factor in Indonesia

Abstract

In the development and implementation of a communication system, QoS is one of the main objective that must be considered. Same goes with LoRa, which is also a communication system designed to be implemented in IoT. However, the focus of IoT is a low powered system that could handle a lot of end devices, different with other type of communication that focus on speed and bandwidth to transfer multimedia files. To be able to reach the maximum effectiveness, a LoRa system must be set with the correct Spreading Factor (SF) based on the distance between client and gateway. This study had conducted a test to analyze the best SF used in some various distance, using 925 Mhz ISM frequency band in Indonesia. Based on the measurement, SF recommendations are SF7 for maximum throughput, SF8 for a balance of high throughput and long-range capabilities, and SF11 for maximum range and optimal range for LoRa application.
