Compute the indoor propagation in a multi-story office building with an antenna
placed on the fourth story and two antennas placed on the third story.
Model Type
The building has five stories, which include the ground floor. Three different
prediction planes are used for result visualization.
Sites and Antennas
There are three sites at different locations in the office building for better
coverage:
Site 1 has an omnidirectional transmitter antenna operating at 2 GHz and is
located on level 4 in the building (antenna height 17.30 m above ground
level).
Site 2 and Site 3 have transmitter antennas operating at the same carrier
frequency of 2 GHz. These two sites are located on level 3 of the building
at 13.6 m above ground level.

Computational Method
As the model is a large multi-story building, the computation method used for such
models is the dominant path model (DPM). DPM focuses on the most relevant path, which
leads to shorter computation times compared standard ray tracing model (SRT).
Tip: Click Project > Edit Project Parameter and click the Computation tab to change
the model.
Results
Figure 2 shows the
propagation results received at Site 3 from each transmitting antenna
individually.
