The 2012 World Radiocommunication Conference (WRC-12) allocated the 694-790 MHz (700 MHz) band for the mobile service on a co-primary basis with other services including digital terrestrial television service in Region 1. Countries of Region 1 will also be able to continue the use of these frequencies for their digital terrestrial television services. This allocation of mobile service in Region 1 in 700 MHz band became effective after the WRC-15. The objective of this article is to assess the electromagnetic compatibility of mobile broadband (LTE) and Digital Video Broadcasting - Terrestrial (DVB-T and DVB-T2) operating both in 700 MHz band. The study contains an assumption of a preferred frequency division duplex (FDD) channelling arrangement which contains confined 2x30 MHz block: 703-733 MHz (uplink) and 758-788 MHz (downlink). The model consists of two elements, LTE network and DVB-T / DVB-T2 (DVB-T/T2) system. Co-channel scenario was analyzed in this paper, and possible impact of LTE base stations to DVB-T/T2 fixed outdoor reception receivers. The Minimum Coupling Loss (MCL) method and Monte Carlo simulation within SEAMCAT software was used for interference analysis. The MCL method was chosen to show single interferer scenario of LTE base station, the GE06 predetermined trigger field strength value was also used in this study. The Monte Carlo simulations investigated cumulative effect of LTE network. During simulations the propagation model was used Recommendation ITU-R P.1546-5. The results obtained provide the minimum coupling distance required between LTE and DVB-T and DVB-T2 in the 700 MHz band to maintain the necessary performance level of the DVB-T/T2 systems.
