ABSTRACT
Smart city services nowadays are gaining popularity worldwide. Russia is not an exception. Since early 2000’s smart city market is growing steadily and, according to forecasts, will continue to grow. Today, the possible applications of smart city services cover a wide range of sectors – from energy production, distribution and consumption to sustainable mobility and waste management. All the innovative services require millions of monitoring sensors and control devices to be connected between each other and to a management platform. Hence, new types of wireless communication networks that meet the specific requirements of smart city services are needed. LoRaWAN is the most promising M2M (Machine-to-Machine) communication technology among other LPWANs such as NB-IoT and SigFox. Conducted field study of LoRaWAN gateway coverage in different conditions shows the LoRaWAN attenuation coefficient in conditions of city center and outskirt and reveals the factors on which the signal attenuation coefficient depends.
