Empirical Coefficients

Compute indoor propagation using empirical coefficients.

Model Type

The propagation project is for an indoor scenario for a single-story building. The simulation is done for only a single prediction height at 1.5 m above the ground.

Sites and Antennas

There is only a single omnidirectional transmitter, situated at a height of 2 m and operating at 2 GHz.
Tip: Click Project > Edit Project Parameter and click the Sites tab to view the sites and antennas.

Computational Method

This project uses standard ray tracing without a preprocessed database.
Tip: Click Project > Edit Project Parameter and click the Computation tab to change the model.

This model uses empirical material parameters, for example, minimum loss of incident ray, the maximum loss of incident ray, and loss of diffracted ray. Empirical material properties are often easier to obtain than physical parameters.

Results

Propagation results show, at every location, the power received from the transmitting antenna. The results are shown for a prediction plane at a height of 1.5 m from the floor.
