Traffic
/ Load Analysis
CelPlanner™
can acquire information from different sources, and distribute it according
to the demographic regions. CelPlanner™
accepts multiple demographic data, represented as residential, commercial,
vehicular, and special events. To determine the positioning of calls,
the distribution of subscribers must be known.
Traffic grids can be created with different resolutions, and the source
of the demand data can be extracted in a number of different ways such
as:
-
A fixed amount of traffic can be distributed across the analysis area.
- Traffic
information can be obtained directly from the demographic data.
- Traffic
layers can be created for different building levels, allowing for
modeling of multiple height effects.For
networks in live operation, traffic
information can be obtained from the switching equipment.
Furthermore,
the demographic data can be distributed according to morphological types,
providing a much more realistic distribution.
CelPlanner™
has incorporated Monte Carlo techniques to implement the most advanced
CDMA predictions in the market. A CDMA prediction is affected not only
by RF propagation factors, but also by the geographical distribution
of the calls. Several factors are interrelated in a CDMA prediction,
including the positioning of the cell sites, the interference generated
by each call, the hand off parameters, and the number and location of
calls. These and several other elements affect the outcome of system
performance. MIMIC provides the precise calculation of load levels (total
interference power), noise rise levels, statistical distribution for
traffic channel power allocation, and the amount being attended by soft
hand-offs, so critical in CDMA systems, in order to obtain precise and
correct predictions.
