Propagation of electromagnetic waves in large areas with
only a small density of buildings should be computed
with rural propagation models. As these models are very
flexible they can also be used if no building data is
available in urban environments
Generally, rural propagation models work perfectly if
the transmitter (basestation) is located on a hill (or
very tall building/mast) and there is nearly line of
sight (LOS) to most of the receiver locations (For NLOS
scenarios additional correction terms could be used).
This is a typical rural propagation environment.
Propagation Models
WinProp offers a wide variety of propagation models for
rural scenarios.
More information about each propagation model is
available after clicking on the corresponding links.
Databases
The topography of the scenario has a very strong
influence on the propagation of the electromagnetic
waves. Therefore a detailed topographical database is
mandatory for rural propagation models. Additionally to
the topography, the land usage (water, roads, buildings,
forest,...) influences the propagation of
electromagnetic waves. Therefore clutter (morpho)
databases can be used optionally to improve the accuracy
of the path loss predictions. Clutter databases should
have the same resolution as the topographical database
(or even finer resolutions). In WinProp the user can
define frequency dependent losses for each clutter class
- these clutter dependent losses can be calibrated
automatically with measurements. The clutter classes can
also be used to control the selection of propagation
models (e.g. selection of submodels of Hata-Okumura
model) and the electrical properties of the ground can
be defined for each clutter class to improve the
accuracy of the ground reflected ray in the
deterministic two ray model. More information concerning
the databases can be found on the
database page.
