Digital Dividend is the spectrum available from the release of very precious spectrum when full migration of analog terrestrial television transmission towards digital terrestrial television transmission has been fully undertaken. What makes Digital Dividend is extremely important is that the fact the spectrum located in lower UHF band below 1 GHz. Therefore, it is optimum in terms of the need of coverage and bandwidth. The main potential services in Digital Dividend are mobile broadband and digital terrestrial broadcasting. The objective of this study is to find out the minimum guard band and minimum distance between mobile broadband and digital terrestrial broadcasting. The interference analysis has been undertaken using SEAMCAT (Spectrum Engineering Advanced Monte-Carlo Analysis Tool) software. Several scenarios between DVB-T and E-UTRA, such as co-channel and adjacent-channel interferences, variation of distance between DVB-T and E-UTRA devices, and different directions of link have been studied. The results obtained provide some figure regarding the minimum guard-band required and minimum distance between DVB-T and E-UTRA systems.
