Innovation Strategy 2019-2030, the Digital Czech Republic concept, Action Plan 2.0 and others. Thus, many measures are already approved and being implemented. Furthermore, an analysis of the state of development of high-speed networks in the Czech Republic is currently being finalised, which will form the basis for the preparation of a new National Plan for the Development of Very-High-Capacity Networks. However, it is already clear that it will require the spending of tens of millions to billions of crowns in the national budget to support the construction and utilisation of 5G networks. The costs of the construction and utilisation of these networks will have to be incurred by business entities, and will amount to up to tens of billions of crowns. This document is linked to the Innovation Strategy of the Czech Republic 2019-2030: IV. The Digitisation pillar and the Digital Czech Republic strategy, together with the second pillar “Digital Economy and Society” and its objectives No. 04 PROMOTING CONNECTIVITY AND INFRASTRUCTURE OF DIGITAL ECONOMY AND SOCIETY, namely the first point 4.01 Construction of electronic communications networks. At the same time, it is desirable to continuously perceive the process of identifying key factors, research requirements, scientific routing and fundamental experimental issues related to the development of other mobile systems, such as the 6G system. Wireless intelligence in these mobile systems will not only concern data transmission, but will become the framework of communication services. Specific intelligent user operations will be transferred to smart, high-capacity data centres built on state-of-the-art technologies, and the integration of mobility-related scanning, imaging and high-precision positional capabilities will represent new visions for future applications and services. 2 5G Network Technology 2.1 Prerequisites for the construction of 5G networks A prerequisite for successful implementation of 5G networks is the existence of high-capacity connection of base stations (so-called mobile backhaul). Research in the field of 5G networks shows that, in view of the demands on these connections, it is essential to implement them mainly with fibre optic transmission systems. Therefore, optical connections will be presumably utilised from the lowest to the highest network level with a capacity dimensioned with a view to further development. In order to successfully implement high-speed electronic communications networks, it is necessary, among other things, to implement the measures included in the Government-approved “Action Plan 2.0 to implement the non-subsidised measures to support the planning and construction of electronic communications networks” submitted by the Ministry of Industry and Trade. 2.2 Deployment of 5G networks Development around the world and Europe shows, that the deployment of 5G networks will take place in two phases. The fourth generation of mobile networks will be used in the first phase, based mainly on LTE technology, which will be modified mainly to apply the 5G network deployment scenario for eMBB, the “improved highspeed and high-capacity mobile networks and services”. This will increase network capacity and speed while gradually reducing latency. This means that even though some operators today refer to their networks and services as 5G, they are actually in this first phase, also known as Non-Standalone (NSA). In the Czech Republic, this has already been tested and implemented in certain selected places. Greater deployment can be expected from 2020. The situation in the Czech Republic is also in line with the global development, because at present, only NSA networks have been deployed around the world. 6
