Increasing the ERP from 50 dBm to 70 dBm results in a reduction of the guard distance up to 20 km for both hTV=100 m (from 70 km to 50 km) and hTV=200 m (from 60 km to 40 km).
In this section we analyse the effect of the DVB-T transmitter on the mobile network assuming that the two systems operate on the same channel and at a distance equal to the guard distance defined and computed in the previous sub-section.
Obviously worst cases are obtained for higher DVB-T transmitter ERP and antenna heights, as this causes the increase of the interferer signal strength and the reduction of the guard distance, and for a percentage of time equal to 1%, as this corresponds to lower attenuation values in the ITU-R P1546 propagation model.
