The Internet Of Things

The launch of the new mobile network technology has paved the way for advanced and more productive industrial applications based on high-speed and low latency services offered by 5G. One of the key success points of the 5G network is the available diversity of cell deployment modes and the flexibility in radio resources allocation based on user’s needs. The concept of Pico cells will become the future of 5G as they increase the capacity and improve the network coverage at a low deployment cost. In addition, the short-range wireless transmission of this type of cells uses little energy and will allow dense applications for the internet of things. In this contribution, we present the advantages of using Pico cells and the characteristics of this type of cells in 5G networks. Then, we will do a simulation study of the interferences impact in uplink transmission in the case of PICO cells densified deployment. Finally, we will propose a solution for interference avoidance between pico cells that also allows flexible management of bands allocated to the users in uplink according to user’s density and bandwidth demand.

The issue of the expanding access to the high-speed Internet through 4G wireless mobile network has been studied in the article. The purpose of the research was to determine the vectors for the development of Internet access through mobile devices in the world and the stage of implementation of these technologies in Ukraine by the case of Dnipropetrovsk region.The methodological basis of the study was the comparative analysis and the Foresight methodology. Documents of international organizations, open source data on the use of 3G / 4G technology by mobile network providers in the territory of Dnipropetrovsk region, expert surveys of specialists of governing bodies in the united territorial communities have been used as information sources. Speeds of mobile Internet networks in countries around the world have been reviewed by authors, paying attention to the current availability of 4G network coverage using mobile devices with the required operating frequency ranges and high requirements to network speeds. The result of the paper became the determination of relations between the spread of 3G / 4G mobile network and development of the e-governance in the studied territories. In particular, this includes the level of development and functioning of local governments’ web portals, ensuring the access of population to the public information and electronic public services. A comparative analysis of the open statistic data on Internet access through mobile devices in the EU and Ukraine has been made. The basic stages of mobile 3G, 4G and 5G generations networks implementation in Ukraine have been described. The available possibilities for mobile devices made for use on 4G networks have been presented.The research of the state of 3G / 4G network coverage in territories of 60 united territorial communities of Dnepropetrovsk region has been carried out and the data on aggregated integrated coverage indicators of 3G / 4G network have been systematized. It has been proven that the use of 3G / 4G technology creates opportunities for the digital inequality’s overcoming and further development of the e-governance in Ukraine. A number of concrete directions of optimization of public administration bodies’ activity in this sphere have been suggested.
