Introduction
|
Combined Network Planning (CNP) is one of the outstanding features of
WinProp.
Each radio network plannin tool offers various propagation models for
rural,
urban, or indoor
environments. But all these models are dedicated to a single scenario.
But which model should be used in case of an hybrid
scenario like
- rural <=> urban
What should be done if the vector building data is only available for a
part of the coverage area?
Pixel based
propagation models will not be accurate enough in the city
center and the urban vector-based
models will not be able to predict such large areas
required for the determination of the interference around the city
center.
Either use CNP
or neglect the
vector building data and use the clutter data for the whole area (also
where vector data would be
available).
- urban <=> indoor
How to determine the coverage of outdoor transmitters inside complex
multi-floor buildings?
How to consider the radiation of indoor base stations in the
interference and coverage prediction around the buildings?
Either use CNP
or neglect the indoor walls and limit the prediction on the outdoor
building data (even if the indoor building data would be
available).
- suburban <=> urban <=> indoor
How can indoor building data be integrated into a prediction in a
suburban scenario?
Either use CNP
or neglect the buildings and walls inside the buildings (even if the
data would be available).
For all these questions, WinProp offers the perfect solution to close
the gaps between the different scenarios:
The multi
scenario models based on WinProp's innovative combined network planning
(CNP).

CNP
Modules
|
|
CNP modules are required for two different transitions between
scenarios:
|
|
|
The
transition between urban and indoor propagation models is very
important for
-
the penetration of
buildings
-
the analysis of the
interference between indoor and outdoor transmitters.
WinProp
offers now a very flexible interface to handle the transition
from urban to indoor and vice versa.

The
transition between rural and urban propagation models is very
important fo
-
the coverage of urban
urban city centers from transmitters located on hills outside the city
-
the coverage of rural
areas outside the city with transmitters located in the city
-
the analysis of the
interference between rural and urban transmitters.
WinProp
offers now a very flexible interface to handle the transition
from rural to urban and vice versa.
