N2 - In this study, the behavior of interference is investigated for cellular mobile radio networks. More explicitly, this work focuses on examining how interference evolves with respect to time under long and short term fading together for the uplink of an FDD system. The results show that decorrelation distance of shadowing plays a crucial role in predicting future interference conditions. Given the initial interference measurement, it is shown that the future interference levels are highly dependent on maintaining the decorrelation distance through the observation interval. On the one hand, if the observation interval is kept too short in a mobile environment, then a drastic deviation in the new interference level from the previous one is not expected. On the other hand, if the observation interval is kept too long, then spatial correlation of shadowing loses its significance and drastic deviations are more likely in the new interference levels; furthermore, path loss might dominate the interference status due to longer displacements.
