The predictions of our model are based on the knowledge of topography, clutter type, and height information. Many different configurations (influence of vegetation, modeling of urban areas, large scale effects, water zones, etc. and combinations of all of these) have been investigated, and the result takes into consideration theoretical and empirical approaches.

Some comparisons between TOM Predict TM performances and those of some classical models can be found in the following paragraph.


Holland, 1800 MHz

The Okumura and COST-Hata models used here are extended versions, that can be used for a frequency of 1800 MHz.
