The wave propagation engines PRO-U
and PRO-R of the WinProp
software package is fully integrated into ATOLL,
the radio network planning solution of Forsk. Atoll is a
windows-based radio network planning (RNP) tool that supports wireless
telecom operators during the whole network lifetime.
The WinProp plug-in for the Atoll tool includes the dominant path model as well as
the 3D IRT (Intelligent Ray Tracing)
model.
Both deterministic models are based on the evaluation of topographical (DTM) and 3D
building data (building data either derived from clutter heights or given as
3D vector data)
and allow the coverage prediction in urban scenarios incl. indoor
penetration.
Due to the deterministic approach a high accuracy is achieved which has been
verified by taking into account numerous measurement campaigns. The
computation time is in the range of minutes and therefore far below
other deterministic models. The auto-calibration of model parameters
based on measurement data is possible and ensures high accuracy in
specific scenarios.
Depending on the clutter the transition to the Atoll standard
propagation model can be utilized, i.e. prediction with WinProp model
in urban area and with the Atoll standard propagation model outside the
urban area. A corresponding polygon around the urban area is defined
automatically based on the clutter data. The interaction between both
models ensures a smooth transition.
Furthermore the dominant path
propagation model allows predictions in large areas without
building data based only on the evaluation of topographical (DTM) and land usage (clutter) data
(incl. individual heights for each clutter or clutter and
frequency-dependent attenuations).
By using the highly
accurate wave propagation models the network
design especially within dense urban environments reaches a new
quality. The Plug-In for Atoll provides sophisticated wave propagation
models
for urban, suburban, and rural scenarios.
The combination of the deterministic models (either 3D Intelligent Ray Tracing (IRT) or Urban Dominant Path Model) and
the empirical COST 231 Walfisch-Ikegami
model leads to one of the best and most accurate approaches to urban
propagation modeling.
