extra loss/ gain at certain "attributed" areas. This will definitely improve the accuracy
of prediction. Furthermore, with accurate signal coverage, interference can be further
controlled.
Figure 4.2.8.4 shows an addition to the generic approach by applying attributes that
enable the model to be more accurate. Along this radial path, the model needs to be able
to handle many attributes. The radio wave travels over and/ or through the buildings,
the treetops, and the water, and in an open area encountering the terrain effect. The
generic path loss can be used as the baseline, but other propagation factors can be easily
added into the propagation prediction with the help of the attribute files.
