WinProp is a complete suite of tools in the domain of wireless propagation and radio network planning. With applications
ranging from satellite to terrestrial, from rural via urban to indoor radio links, WinProp’s innovative wave propagation models combine accuracy with short computation time.
View the typical workflows when working with propagation simulations in specific scenarios, how to add a network planning
to a propagation simulation, include a receiver pattern, set up a time-variant scenario, include multiple-input multiple-output
(MIMO) at both the base station and the mobile station, connectivity analysis of sensor networks and optimization.
Use AMan to generate, edit and analyze a single antenna. Superimpose multiple antennas radiating similar signals to determine
the actual antenna pattern while taking into consideration the local environment.
WinProp includes empirical and semi-empirical models (calibration with measurements possible), rigorous 3D ray-tracing models
as well as the unique dominant path model (DPM).
In WinProp various air interfaces and applications are pre-defined: broadcasting, cellular, wireless access, WiFi, sensor networks,
ICNIRP and EM compliance.
Calculate rural satellite coverage from a geostationary communications
satellite.
Model Type
The geometry is described by topography (elevation) and clutter/morpho (land
usage).
Sites and Antennas
A single site, denoted Satellite 1, is located at a height of 36000 km and is
a geostationary satellite. The antenna has an EIRP1 of 90 dBm at a
carrier frequency of 2 GHz.
Tip: Click Project > Edit Project Parameter and click the Sites tab to view the
antenna settings.
Computational Method
The coverage is computed with the empirical two-ray model
(ETR) model. For pixels in
shadow areas, knife-edge diffraction is added for improved accuracy. Without this
addition, ETR would compute the path
loss to each pixel assuming that the direct ray and the ground-reflected ray exist,
which would be incorrect in shadow areas.
Tip: Click Project > Edit Project Parameter and click the Computation tab to change
the model.
Results
Propagation results are computed at a prediction height of 1.5 m and include power
coverage of each transmitting antenna and path loss. The power coverage (power
received by a hypothetical isotropic antenna) is shown in Figure 3.
