Implementation of the 5G network in the operations of Hrvatski Telekom d.d. (HT) represents a turning point in the development of telecommunications infrastructure in Croatia. This project has far-reaching effects on technological progress, economic growth, social inclusion and overall competitiveness of HT in the telecommunications market. The introduction of 5G technology brings significant improvements in data transfer speed, reduction of latency and network capacity. 5G enables faster and more reliable internet, which is essential to support advanced applications such as autonomous vehicles, smart cities, telemedicine and augmented reality. Hrvatski Telekom uses advanced technologies such as Massive MIMO (Multiple Input Multiple Output) and edge computing to optimize network performance and ensure high quality of service. The implementation of the 5G network provides HT with numerous business advantages. First, it enables the diversification of services by offering advanced applications such as 4K/8K video streaming, cloud gaming and IoT services. Second, improved network infrastructure increases user satisfaction and reduces the number of service quality complaints, which positively affects user experience and loyalty. Third, 5G enables HT to reduce operational costs through automation and optimization of network operations. Hrvatski Telekom has ambitious plans for further development and expansion of the 5G network. Plans include further optimization of network performance, expansion of coverage to the whole of Croatia and application of new technologies such as artificial intelligence (AI) and blockchain. HT also plans to collaborate with academic institutions and technology partners on research and development of new applications and services that will further improve user experience and support digital transformation.
