Office Building with Antenna and Radiating Cable

Compute the indoor propagation in a multi-story office building with a single antenna, and a radiating cable is placed on the ground story.

Model Type

The building has five stories, which include the ground floor. The simulation is done for only one prediction height at 1.5 m above the ground.

Sites and Antennas

There are two sites at different locations in the office building:
  • Site 1 has a dipole antenna operating at 2.4 GHz at a height of 2.5 m.
  • Site 2 has a radiating cable installed.

Computational Method

As the office building consists of several stories, the computation method is the dominant path model (DPM). DPM focuses on the most relevant path, which leads to shorter computation times compared to standard ray tracing model (SRT). The radiating cable has gaps (slots) in its outer sheath to allow the signal to radiate along its entire length. Therefore a special prediction model is used to predict wave propagation. The shortest distance model predicts the received power using the shortest geometric distance between the radiating cable and the receiving point.


Figure 2 and Figure 3 show the propagation results received at Site 1 and Site 3 from each transmitting antenna individually.
