摘要

The 694-790 MHz band (700 MHz) known also as the second digital dividend was allocated to the mobile, except aeronautical mobile, service on a co-primary basis with other services to which this band is allocated on a primary basis in Region 1 and identified to International Mobile Telecommunications (IMT) by the 2012 World Radiocommunication Conference (WRC-12). The allocation of mobile service in Europe and in other countries of Region 1 in 700 MHz band got effective after the 2015 World Radiocommunication Conference (WRC-15). Countries of Region 1 will be able to plan and use these frequencies for mobile services including IMT. The objective of this paper is to assess the electromagnetic compatibility of Digital Video Broadcasting-Terrestrial (DVB-T/DVB-T2) and mobile broadband (LTE) operating both in 700 MHz band. The research contains an assumption of a preferred frequency division duplex (FDD) channelling arrangement 703-733 MHz (uplink) and 758-788 MHz (downlink). The model consists of two elements, a DVB-T/DVB-T2 system and LTE network. Cochannel scenario was analyzed in this paper, and possible impact of DVB-T/DVB-T2 to LTE base stations receivers. The Monte Carlo simulations within SEAMCAT software were used for interference analysis. The Monte Carlo method provides more relaxed electromagnetic compatibility scenario. For SEAMCAT simulations was used Recommendation ITU-R P.1546-5 propagation model. The results obtained provide the minimum coupling distance required between DVB-T/DVB-T2 and LTE networks in the 700 MHz band to maintain the necessary performance level of the LTE system.
