Hilly Terrain

Calculate propagation in rural/suburban scenario for hilly terrain.

Model Type

The geometry is described by topography (elevation) as well as clutter, see Figure 1. The Database tree enables you to change between topography (terrain elevation at every pixel) and clutter view.

Figure 1. Clutter (land usage).

Sites and Antennas

There are two antenna sites in this scenario. Site 1 has two directional antennas at a height of 25 m, and Site 2 has an omnidirectional antenna at a height of 50 m.

Tip: Click Project > Edit Project Parameter and click the Sites tab to view the sites and antennas.

Computational Method

The method is set to the Hata-Okumura model. Land usage is taken into account under the settings of the Hata-Okumura model.
Tip: Click Project > Edit Project Parameter and click the Computation tab to select the method and change its settings.


Results are computed for each transmitter at a prediction plane of 1.5 m.

Propagation results include power coverage for each transmitting antenna of all sites. This is the power that an isotropic receiver at a given position would receive from the transmitter. Propagation results also include field strength, path loss, and line-of-sight results. The LOS results for Site 2 Antenna 1 and Site 1 Antenna 2 are given in Figure 2 and Figure 3.

Figure 2. Line-of-sight results for Site-1.

Figure 3. Line-of-sight results for Site-1.

Results for received power are shown in Figure 4. Note the low power levels in non-line-of-sight areas. The Hata-Okumura model on its own would over-estimate the received power in such areas, while the addition of knife-edge diffraction produces more realistic results.
