The Long Range (LoRa) technology was first developed by SemTech Company. LoRa is a wireless technology developed for long-range, low-power, low-bit rate and chirp spread spectrum (CSS) radio modulation technology, it also provides the ability to connect to sensors more than 15-30 miles away in rural areas.In this study, we present the LoRa system architecture with the functionality of each component and several typical application scenarios of LoRa network.LoRa is widely used into many applications, such as smart metering, factory monitoring and also it can be used to provide sensor information to communities to provide disaster alerts. LoRa networks allow for very long wireless links that can connect villages and towns. LoRa network is emerging as one of the most promising Low Power Wide Area networks (LPWAN).LPWANs represent a new trend in the evolution of the wireless communication designed to enable broad range of Internet of Things (IoT) applications.

Media Access

In low-power wide area networks (LPWAN), a considerable number of end devices (EDs) communicate with the gateway in a certain area, whereas for transmitted data, a low data rate and high latency are allowed. Long-range (LoRa), as one of the LPWAN technologies, considers pure ALOHA and chirp spread spectrum (CSS) in the media access control (MAC) and physical (PHY) layers such that it can improve the energy efficiency while mitigating inter-cell interference (ICI). This paper investigates the system throughput of LoRa networks under the assumption that the interferences between EDs for exclusive regions are ignored using CSS. In order to establish an analytical model for the performance of LoRa, we introduce the pure ALOHA capture model, which is the power threshold model. For this model, we assume that the interfering power is proportional to the length of the time overlapped. In addition, we discuss LoRa gain by comparing the total throughput of LoRa with that of non-CSS.

Radio Communication System

The manner of efficiency and effective of power usage is the main objective in electricity consumption, one major steps to control the usage is by providing a monitoring to aim the power usage data and process it to information needed. Internet of Things benefit in power and electricity has involved sensors to work as data reader continuously.  LoRa or well known as Long Range radio communication system work with chirp spread spectrum which work from 920 to 923 Mhz in Indonesia. This paper presents implementation of LoRa system to support the prototype of energy monitoring in Solar Home System off-grid

AbstractRecently, low power wide area networks are attracting a lot of attention by the research community. They are wireless technologies characterized by large coverage area, low bandwidth and long battery life. One of these low power wide area networks technologies, the long range wide area network, can be used for different monitoring applications for health, agriculture, traffic, smart city.In this paper, different simulations and experiments are conducted to implement a low-cost long-range wide area network environmental monitoring application for Tirana city in Albania. Simulation and experimental data are compared and similar results were obtained. In the low-cost implemented system, the gateway can communicate with the sensors placed in strategic positions with long distance covered also using Radio Mobile software.
