The Internet of things brings to life a new set of services that can be deployed on the mobile network operator and offered to the end user, for example, services such as: tactile Internet, augmented reality, virtual reality, medical networks, weather forecasting, smart homes and smart cities, completely automated cities with smart self-learning algorithms for managing everything. This paper considers the possibility of implementing services of the 'Smart City' concept. Based on the experience of other cities, we can conclude that the most interesting and popular will be the implementation of intelligent street lighting, that allows the municipality to save budget funds, spent on street lighting in the city. For implementing this service, using a standardized wireless technology for building a physical network and a unified service model, in future it will be possible with minimal investment to increase the number of services, adding, for example, air pollution analysis, or 'smart' waste containers. In this paper we analyze wireless technologies with low power consumption and long range. Based on the analysis was chosen the best technology, which can be used in smart city to provide a 'smart street lighting' service. In results model for providing 'smart street lighting' service was developed, which includes equipment, the scheme of the overall network organization, as well as its logical implementation in a unified service model, and also in this work we tested the network segment built using the selected wireless technology LoRa.
