In 2007 the frequency band 450-470 MHz (450 MHz) was identifled in ITU Radio Regulations for use by International Mobile Telecommunications (IMT) in all three ITU Regions. The frequency band or part of it is used by many applications, e.g., Professional Mobile Radio/Public Access Mobile Radio (PMR/PAMR) in European countries. To introduce a new generation evolving public cellular networks, e.g., Long Term Evolution (LTE)/New Radio (NR) in the 450 MHz band the appropriate electromagnetic compatibility studies shall be performed. The aim of this study is to evaluate the electromagnetic compatibility of mobile service and Digital Terrestrial Television Broadcasting (DTTB) service operating in adjacent frequency channels. The minimum Coupling Loss (MCL) and Monte Carlo methods were used in order to investigate interference level. The obtained results identify the minimum separation distance required between mobile service LTE/NR stations and DVB-T and DVB-T2 in order to avoid the harmful interference.
