Considered Map
Data
|
|
The map data
considered during prediction is an important factor for
achieving highly accurate results.
-
Topographical Databases: The consideration of
topography is necessary.
-
Clutter
and Land Usage: Traditionally for each clutter class
a specific loss is defined. But WinProp works
additionally with the heights of the objects in the
clutter class and the clearance around them. This
improves the accuracy of the prediction significantly
and requires less tuning.
-
Vector
Building Data: Today, wireless networks must provide
high data rates inside buildings. Therefore the actual
buildings cannot be ignored in the predictions. The
waveguiding in street canyons as well as the
diffractions at roofs and wedges are dominating the wave
propagation in urban scenarios. WinProp’s unique
Dominant Path Model (DPM) considers optionally the
vector data of the buildings to include the most
important propagation effects. This leads to a very high
accuracy.
-
Trees and
vegetation: Trees and parks attenuate the
propagation of electromagnetic waves. Vegetation areas
are considered in the prediction and characterized by
their heights and by a specific attenuation (dB/m).

Hata-Okumura Model
Four submodels
(open/suburban/medium urban/dense urban) available.
|
|
|

|
|
Two-Ray Models
Direct ray
and ground reflected ray are considered. Either
deterministic or empirical.
|
|
|
|
|
|
Knife Edge
Diffraction Extension
Based on
Hata or Two-Ray Model, but consideration of multiple diffractions due to
topography, clutter objects, and buildings between
Tx and Rx.

3D
Dominant Path Model
Semi-deterministic 3D approach for determination of
the dominant path.

Output
|
|
The main output
is the coverage map (path loss map) displayed in Aircom
Enterprise. Additionally there are a lot of further outputs
available which can be visualized in the
WinProp ProMan
software or which can be used for a further analysis of the
radio channel in other tools, e.g. Matlab.
