Dependence of Electric Field Strength Prediction Model Accuracy on Database Resolution

A macrocell electric field strength prediction model directly depends on accuracy of used terrain and clutter databases, which, on the other hand, directly depend on their resolution. It is difficult to find exact mathematical model of this dependence because many factors influence on it, like particularity of a specific environment and irregularities of terrain. In order to find a proper dependence, an experimental analysis was carried out in the region of Belgrade. The conclusions are based on extensive electric field strength measurements that were carried out in the 900 MHz frequency band
