Existing technologies for long-distance data transmission in the Internet of Things are analyzed. Based on the calculations, the justification of the efficiency of LORA technology is substantiated, the energy potential of the communication line for LORA technology is given, the capacity of the LoRa network is determined. The network architecture has the best relationship between increasing the battery life of IoT devices and providing communication range. The protocol operates in a non-licensed range, and this is its uniqueness in cost and speed of implementation. Based on the study of the experience of implementing the protocol in the city of Lviv, the advantages and problems of implementation were identified.
