Hrvatski Telekom Uses DSS to Test 5G in Croatia

Hrvatski Telekom tested the technology that enabled fast coverage with 5G services in larger areas in Croatia's Samobor. It is a dynamic spectrum sharing technology - DSS (Dynamic Spectrum Sharing), the application of which is crucial for the rapid implementation of 5G technology.

HT has enabled 5G technology on ten base stations in the 2.1 GHz frequency band in the Samobor area, with five base stations in the 3.5 GHz band, which allows for the largest 5G area in terms of speed and coverage in Croatia.

The application of DSS technology enables the current use of existing frequencies for 5G and reduces the need for new base stations and locations on specific 5G frequencies. The 5G technology is crucial for connecting many sensors, industrial devices, drones, and autonomous vehicles, where the reliability of the connection is even more important than the data transfer speed.

It can only be guaranteed by a quality radio signal using frequencies in the so-called medium band 1.8-2.1 Ghz. A commercially available Samsung S20 5G terminal was used to test the 5G functionality.

"By applying dynamic spectrum sharing technology, we tested the largest 5G coverage area by combining 5G technology in separate (3.5 GHz) and shared 4G/5G spectrum (2.1 GHz) and thus made the biggest breakthrough in the development of 5G technology in Croatia. We have once again proven that we have the leading network in Croatia ", Boris Drilo, Member of the Management Board and CTIO of Hrvatski Telekom, pointed out.

Simple and fast implementation of dynamic spectrum sharing technology, which allows existing frequency resources to be dynamically shared between 4G and 5G technology, is possible thanks to the recent modernization of Hrvatski Telekom's entire mobile network. The project, which lasted more than two years, is the most significant private infrastructure investment in Croatia in 2019, and it introduced the cutting-edge 5G ready equipment and advanced services of the future.
