Interdisciplinary Description of Complex Systems, 2022

A number of technological application factors can be highlighted in smart city solutions, where small data and long-range transmission are of primary consideration. These include monitoring energy consumption, operating a smart waste management system, monitoring, and tracking traffic, having smart parking systems, monitoring public lighting, and even detecting various malfunctions. Such smart city systems use IoT technology for data collection. An essential aspect of urban solutions is to ensure the coverage of large areas, both outdoors and indoors, low energy consumption, as well as modularity and mobility. LPWAN technologies can meet these conditions. LPWAN technologies include LTE-M, NB-IoT, LoRaWAN, and Sigfox. Using LoRaWAN technology can be the right solution for these cases. As with any application, it is crucial to clarify the challenges of the application with LoRaWAN. The present study addresses the categorization of LoRaWAN devices and the challenges of technology in smart city solutions. LoRaWAN products used in smart city solutions can be grouped according to several aspects. This article deals with the creation of classifications that facilitate further testing. Smart city application challenge studies are applied to the specified categories. The challenges of the solutions cover several areas. These include technological aspects, aspects of specifications, and aspects of the nature of the application. Another area represents the information security aspects, which is, however, not addressed by this invention.

Analysis of the use of LoRaWan technology in a Large-Scale Smart City Demonstrator

This paper presents analysis of the use of LoRaWan in a large-scale demonstrator of the Smart City, which is conducted at the Scientific Campus of the University of Lille in the North of France. LoRa is used to create a local network to exchange data between sensors and the server, which hosts the smart city management platform. Prior to the installation of this network, a field study was conducted to explore the performances of LoRaWan in the campus. This paper presents the results of this field study. It shows that this technology is well adapted for smart campus projects.

Long Range Wide Area Network (LoRaWAN): An overview and its importance in the world of IoT

The main issues faced by the low power communication standards are its inability to communicate over a fairly long distance. This paper focuses on a fairly new connectivity protocol known as the LoRa which is gaining importance in the world of IoT for its capability to communicate over a long range while exploiting the low power advantages of the conventional LPWAN(Low Power Wide Area Network) protocol. We have discussed the LoRa standard here along with its advantages over other protocols like Zigbee, Bluetooth, Z-wave which till now are reigning the low power wireless connectivity domain.

On the Performance of LoRaWAN in Smart City: End-Device Design and Communication Coverage

DCCN, 2019

Expected communication scenarios within the emerging landscape of Internet of Things (IoT) bring the growth of smart devices connected in the communication network. The communication technologies of greatest interest for IoT are known as Low-Power Wide-Area Networks (LPWANs). Today, there are LPWA technologies (Sigfox, Long-Range Wide Area Network (LoRaWAN), and Narrowband IoT (NB-IoT)) capable to provide energy efficient communication as well as extended communication coverage. This paper provides an analysis of LPWA technologies and describes experimental evaluation of LoRaWAN technology in real conditions. The LoRaWAN technology provides over 150 dB Maximum Coupling Loss (MCL), which together with maximum transmission power (TX) 14 dBm and spreading factor 7 results in theoretical communication distance in units of kilometers. The obtained results from field-deployment in the city of Brno, Czech Republic confirm the initial expectations as it was possible to establish reliable communication between low-end LoRaWAN device and LoRaWAN gateway on the distance up to 6 km.

Applied Sciences, 2020

The application of the most recent advances of the Internet-of-Things (IoT) technology to the automation of buildings is emerging as a promising solution to achieve greater efficiencies in energy consumption, and to allow the realization of sustainable models. The application of IoT has been demonstrated as effective in many fields, such as confirmed, for instance, by the Industry 4.0 concepts, which are revolutionizing modern production chains. By following this approach, the use of distributed control architectures and of IoT technologies (both wired and wireless) would result in effective solutions for the management of smart environments composed of groups of buildings, such as campuses. In this case, heterogeneous IoT solutions are typically adopted to satisfy the requirements of the very diverse possible scenarios (e.g., indoor versus outdoor coverage, mobile versus fixed nodes, just to mention a few), making their large-scale integration cumbersome. To cope with this issue, t...
