This paper presents the preliminary results of a field measurement campaign for the digital terrestrial television DVB-T2 signal in Seoul. This includes an analysis of its horizontal and vertical variations as well as the major link budget factors in planning digital terrestrial television networks for indoor reception, such as height loss and standard deviation of the location correction factor. By modeling the values measured from the obtained parameters as a log-normal distribution, the efficacy of indoor service coverage can be predicted from the target data rate.
