Anotace: This paper is concerned with the analysis of adjacent channel interference of the Long Term Evolution (LTE) mobile system operating in the Digital Dividend into Digital Video Broadcasting – Terrestrial (DVB–T) system. Field measurements in the real LTE network have been conducted in order to define the most significant scenarios and for each of these, Protection Ratios have been quantified. Variable load on the LTE base station has been taken into consideration. Therefore, Protection Ratios for the LTE base station in idle state, and fully dedicated mode have been calculated. Interference mitigation techniques have been reviewed, and an effective deployment method has been proposed.
