Design and implementation of LoRa – GSM Gateway nodes monitoring based on LoRa technology

Abstract

      LoRa (Long Range Radio) is a low-power, long-range data transmission wireless technology for M2M and IoT applications.. The authors of the article have designed and implemented a LoRa– GSM (Global System for Mobile Communications) gateway with integrated HMI (Human Machine Interface) touch screen, to communicate with the operator instead of  the LoRa server. Gateway filters and uploads data to the IoT server via GPRS/3G/4G mobile network, which is suitable for all geographical areas. The LoRa node uses an energy-saving battery-powered wireless sensor that synchronizes with the gateway. The LoRa 433 MHz product has been tested in two geographical areas: urban and rural. The results show that the gateway meets the control requirements and data transmission with high reliability and stable control decision-making; and that it can be used in industry, environmental monitoring, agriculture and smart healthcare.
