Introduction
|
|
|
The
planning and design of 3G networks comes along with completely new
challenges compared with 2G network planning. Different services and
service mixes as well as dynamic network behavior (e.g. CDMA cell
breathing) and technological influences (e.g. soft handover, fast power
control) have to be considered properly at an early stage of the
network planning process. Due to the fact that these networks are
interference limited, capacity and service coverage are not
independent, and the planning tool has to cope with the mutual
influence.
The
following figure depicts the well known "cell breathing" effect in CDMA
networks.

The
most challenging areas for the deployment of 3G networks are currently urban and indoor environments.
Especially in these scenarios highly reliable propagation predictions
are required as they influence to a great extend the serving cell
assignment and the experienced interference levels. To be able to
consider handover problems due to mobility a realistic cell assignment
and therefore realistic propagation
predictions are required. Advanced propagation models as
implemented in ProMan
are therefore the necessary groundwork for any realistic system
simulation.
System simulations help to evaluate mobile network performance in
different environments with different configurations or network
layouts. Performance indicators of interest are network capacity,
service availability and also service quality from the user point of
view. System simulations are required for the network planning process
and help to come to an cost effective investment in air interface
network infrastructure. This is achieved by reducing the number of Node
B (and sites) to a minimum still fulfilling capacity and service
quality constraints.
