There is one term in future broadcasting technology called Analog Switched Off (ASO) or Digital Switch Over (DSO). DSO is a condition in the future where all analog TV signal will be terminated and replaced by digital TV signal. ASO schedule varies over the world, but the migration itself is predicted will have been done in almost all countries by 2015. In this migration, there will be 336 MHz to be cleared, that is 470-806 MHz. Until now, no standard for digital dividend frequency allocation. Indonesia and many countries in the world are still planning this kind of standard. There are some potential applications of technology that can be applied in digital dividend spectrum, i.e. DTT (Digital Terrestrial Televison), mobile TV, PMSE (Programme-Making and Special Events) applications, cellular, BWA (Broadband Wireless Access), private mobile radio, and so on. In the future, Indonesia will probably adopt spectrum allocation standard from Europe Union and United States. One thing that can be attractive and occur while DSO transition period is channel replacing from DVB-T into mobile broadband services in upper channel of Band V UHF (channel 49-62). This transition potentially causes interference phenomena because these two kinds of technology can probably operate in the same channel (co-channel) or adjacent channel. This study is done by analyzing co-channel and adjacent-channel interference between DVB-T and E-UTRA services using SEAMCAT as the simulator. Simulation results show that the minimum required protection distance between DVB-T and E-UTRA is about 310 km for co-channel case and 9,5 km for adjacent-channel. Generally, there is no need to add any geographic separation between each transmitter when there is at least 4 MHz guard band between DVB-T and EUTRA downlink. Besides, E-UTRA uplink doesn’t seem to disturb reception performance of DVB-T, so there is no need to add any geographic separation or guard band between these two links.
