    Opis:
    In the paper, 5G communication technologies implemented for Intelligent Transport Systems are discussed. Firstly, the essence of the 5G system concept is presented, and the problem of network functions virtualization (NFV) is analyzed. Moreover, the principle of virtualization is explained. Secondly, the analysis of network slicing is performed, from the point of view of transport systems implementation in the future 5G networks. The important part is the analysis of architecture proposals for the 5G communications system, implemented as ITS, for various scenarios of its work. The aim of this paper is the study on practice architecture of the 5G communication network for the ITS system, introduced as physical radio-informatics system implementation.

    Opis:
    The article intends to discuss the impact of the development of IT and logistics systems on the development of ICT networks in the context of practical application in the area of transport, especially in the area of railway transport in Poland. At present, PKP PLK is involved in the construction of a teletransmission network, to be used mainly with ERTMS. According to the author, development of the network should be planned in such a way that this network is able to satisfy the current and future needs of all railway companies in the area of data transmission, making it possible for such railway companies to extend their range of ICT services to include other forms of transport. Systems of railway traffic control should be established within a physically isolated fibre-optic network (isolated fi bres in fibre-optic cables).

    Opis:
    The article aims to explain the importance of 5G technology in pursuing power and shaping the international competition between two superpowers: the USA and China. Accordingly, the research focus of this article is to explain how and why 5G technology is being used by China and the U.S. as a key instrument in their growing geopolitical rivalry. The study is framed within the theoretical approach of offensive realism. It is based on the primary assumption that superpowers like China and the United States tend to increase their power not only by expanding their armed forces and territorial conquests but also by using every possible opportunity to do so. The article researches two questions. What is the importance of 5G technology in the rivalry between China and the U.S.? How has the development of communication technologies influenced countries and their ability to shape the international environment? 5G technology is considered more than just the next generation of wireless connectivity, as it goes beyond traditional forms of use and addresses a new category of users. It is a structure intended to facilitate a new category of goods and services: smart cities, autonomous vehicles, automated factories, digital services, and robotization of decision-making processes.

    Opis:
    Thanks to the availability of mobile devices and the spread of broadband access around the world, the number of network users continues to grow. This has raised user awareness when it comes to the quality of content they consume. Many service providers and operators focus on monitoring QoN (Quality of Network) and QoS (Quality of Service) parameters, particularly those influenced by bandwidth and latency. However, for most end-users, quality is understood as the subjective QoE (Quality of Experience), a mixture of several individual factors. This paper presents a QoN evaluation, carried out under real-time operating conditions at a university campus, considering the overall performance of the cellular network. The study involved 50 mobile devices, i.e., smartphones, used by students during their typical activity throughout a week. The results were gathered on the eve of 5G, using a custom-built Android application. This application enabled the acquisition of valuable data about the wireless link, including download and upload speed, latency (pink), the ID of the serving base station, and type of cellular connection. This approach can be used to detect the strengths and weaknesses of back-end networks.

    Opis:
    The COVID-19 pandemic has significantly limited user mobility, not least among students. Remote learning had a particular impact on resource allocation in relation to using terrestrial cellular networks, especially 4G systems in urban agglomerations. This paper presents the results of a quality evaluation of an outdoor environment, carried out between 2019 and 2021 on the campus of a technical university. Annual studies are conducted using our own custom-built mobile application, installed on 50 mobile devices (i.e., smartphones) running Android OS. This study aims to determine the impact of reduced user mobility on access parameters in mobile networks, that is, both download and upload throughput as well as delay (ping), with a particular focus on serving base transceiver stations (BTSs). This research scenario involves long-term evolution (LTE) compatible user equipment (UE) that operates under four Polish mobile network operators (MNO), which includes roaming connections and the newly launched 5G standard.
