Monitoring System in Lora Network Architecture using Smart Gateway in Simple LoRa Protocol

LoRa is a low power wide area network communication that has ability to transmit data in a long range with a low power. Lora Alliance has designed a network architecture that usually used, called LoRaWan. The implementation of LoRaWan itself has not meet the requirement of LoRa as one of the LPWAN protocol because it still depend on the internet in processing and displaying data. To meet the purpose of Low Power Wide Area Network (LPWAN) such as simple implementation, low cost, and simple architecture, this research using Simple LoRa Protocol (SLP) with Raspberry Pi 3b+ as the smart gateway. The module used is Dragino LoRa that work in 868 MHz with Spreading Factor 7 and Arduino UNO for the client. The architecture build used in this research implemented to a monitoring system. The system build only to access a Local Area Network. Result showed that the smart gateway could handle the LoRa communication and the monitoring information system together. It also showed that the system average throughput is 489 bit/s and has packet loss 26% at 1-meter distance.
