Features
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.
The manipulation of this traffic data is a unique feature within CelPlanner™.
The software can generate either statistical random or regular call
patterns, accurately simulating real systems behaviour. This unique
and powerful combination results in an unprecedented capability in predicting
wireless systems behaviour when facing different patterns of traffic
load. As such, the traffic simulation can determine the precise number
of traffic channels required in each sector for ANALOG and TDMA systems
for a pre-defined GOS.
Predictions
Accurate
and detailed predictions can be generated to illustrate the network's
coverage and performance. Predictions provide important information
for the RF Engineer on his daily tasks in order to improve his effectiveness.
Some of the predictions are listed below:
- Individual Forward
and Reverse Signal Levels
- Composite
Signal Level
- Best
Server
- BER
- Adjacent,
Co-Channel, and Composite Interference
- Simultaneous
Service Classes
- Handoff
Frequency
Planning
CelPlan®
provides the tools to perform an efficient frequency or resource (DVCC)
planning, with any cellular reuse pattern. Hexagon grids can easily
be generated and manipulated to aid the design process.
