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
A fixed amount of traffic can be distributed across the analysis area.
information can be obtained directly from the demographic data.
layers can be created for different building levels, allowing for
modeling of multiple height effects.

the demographic data can be distributed according to morphological types,
providing a much more realistic distribution.
has incorporated Monte Carlo techniques to implement the most advanced
UMTS predictions in the market. A UMTS prediction is affected not only
by RF propagation factors, but also by the geographical distribution
of the calls. Several factors are interrelated in a UMTS 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 UMTS systems, in order to obtain precise and
Channel dBm - Graphically presents the pilot channel composite/indivdual
coverage, in dBm. The predicted signal level is calculated at the
user terminal receiver.
Channel Ec/lo - choice is done considering the best Ec/Io
ratio at that point
Forward Traffic - Prediction that represents the Eb/Io ratio
(bit energy/ interference and noise spectral density) for the traffic
channel in the forward link, that is, in the Mobile-Base direction,
in dB. This result is presented in all the points of the terrain within
the configured prediction radius.
Reverse Traffic - Prediction that represents the effective
radiated transmission power (ERP) of the mobile station required to
provide the site with the Eb/Io signal level required in the reverse
link, that is, in the Mobile-Base direction, in Watt. This result
is presented in all the points of the terrain within the configured
Reverse Traffic - Prediction that represents the lower transmission
power of the mobile unit required in each point in order to provide
a station with the Eb/Io level required in the reverse link.

system where all the RBSs use the same frequencies spectrum (frequencies
reuse factor equal to 1), not allowing the RBSs to be identified by
the frequencies used.
