Analysis of Frequency Arrangement for the 600MHz Band

The frequency band 470–694 MHz is harmonised with respect to terrestrial television broadcasting services in ITU Region 1 and has been utilised for this service for several decades. At the same time, it is essential to consistently leverage technological advancements to enhance spectrum efficiency and improve spectrum access. Frequencies below 1 GHz play a crucial role in coverage-dependent services, such as broadcasting and mobile services, owing to the favourable propagation properties of radio waves within this radio frequency range. Mobile service operating in lower frequency bands offer higher coverage, greater availability, and improved indoor service quality. This paper analyses potential options of frequency arrangement for implementing mobile service within a portion of the <tex xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">$470-694 \text{MHz}$</tex> spectrum, i.e., in the frequency band 600 MHz. To maximize the utilisation of the frequency band for mobile communication systems (<tex xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">$5 \mathrm{G}, 6 \mathrm{G}$</tex> etc.), a radio frequency channel arrangement is to be considered that optimises the accessible frequency spectrum, consequently also diminishing a possible radio interference with current radio communication systems.
