Environments
Defining
For each environment, you define the:
• Slow Fading Standard Deviation • Outdoor Fast Fading Margin • Outdoor Penetration Loss • Vehicular Fast Fading Margin • Vehicular Penetration Loss • Indoor Fast Fading Margin • Indoor Penetration Loss
• Deep Indoor Fast Fading Margin • Deep Indoor Penetration Loss
Subscribers
Defining
Different types of subscribers using different
services and equipment require different subscriber definitions.
Subscriber Editor
• The characteristics of
subscribers are defined
using the nodes in the
Subscriber Settings
dialog box.
• Possibility to create a
diverse mix of
subscribers by defining
different services,
quality types, and user
equipment types and
assigning them to
subscriber types.
WCDMA Subscriber Equipment
• Body loss is specified under
service settings in tab Quality of
Service
• Radio bearers defined in
network settings are listed in a
tabular format
• R99/HSPA/HSDPA/HSPA+
terminal category can be
selected (with Ec/Nt setting
defined in network setting)
• All Bearers, can be individually
enabled/ disabled for different
equipment configurations
Subscribers
Services
Subscribers
Understanding Input Load
• The input load is amount traffic contributed by one subscriber
from using a given service
• The type of service and usage pattern determines input load
per subscriber
• The input load and traffic map together determine the
number of active subscribers in each Monte Carlo simulation
run
• Input load is quantified by Erlang per subscriber and
Throughput per subscriber
– For packet data call, input load may be determined according to its call profile
Subscribers
Understanding Activity Factors
• A packet data call consists a number of packet transmissions. The
two consecutive packets are separated by the packet inter-arrival
time. Therefore, transmission of data packets is not continuous.
• From the RF point view, the radio channel is active during packet
transmission, and, inactive during the packet inter-arrival time,
when no packet is transmitted (although from network point of
view, the user is still in active state until a timeout period is
reached).
• The activity factor is defined as the percentage of time when radio
channel transmits on downlink/uplink.
• DL and UL activity factors are used in sector throughput and
interference calculation
Subscribers
Defining DL/UL Activity Factor
• For a circuit switched voice service, the activity factor is typically
40% to 50%
• For packet switched data service, the activity factor varies with
applications and radio bearers used to support the service
• The DL/UL activity factors in the Planet service settings should be
defined according to the lowest DL/UL bearer service data rates
that are allowed for the service.
• The Planet analysis algorithm automatically scales activity factor
when the served by a higher data rate bearer.
• The asymmetry nature of the packet data service can be modeled
by specifying different DL and UL activity factors
Subscribers
Understanding Usage Weightings
• Subscribers in different environment may experience different radio signal fading and losses • Mentum Planet defines four environment types that can be assigned individually to each
clutter class
• The usage weightings determine the traffic distribution in different environment types

Layer Statistics
Generating
Changing the analysis area
Choosing your area of interest
Statistics will be calculated only within the region chosen in the Analysis Area drop-down menu.
New areas can be created by using the Areas function under the Project Data category in Project Explorer.
Ignoring invalid bins
Excluding null values
Depending on the type of statistics that want to be generated, it may be interesting not to include points where the layer being analyzed has no values populated.
In that case, the Exclude null values checkbox can be checked.
Applying filters to ignore unwanted bins
Selecting a grid to filter
The grid you query can be an existing analysis layer or a any other grid you have created/generated before.
Remember you can use the Areas function in Mentum Planet to create grids based on existing polygons.
Applying filters to ignore unwanted bins
Selecting a grid to filter
Enable the Apply area filter checkbox and browse for the grid (numeric or classified) on which you will be applying the filter.

Applying filters to ignore unwanted bins
Selecting a grid to query
The output file will exclude results for any bins where the value of the grid is “Buildings”, so that your stats reflect outdoor points only.
Viewing the stats
Sorting and exporting
In the Report Preview, results will be shown in absolute (km²) and relative (%) numbers, and can be sorted in ascending or descending order.
This report can be exported to Excel or CSV format.
Creating graphs
PDF/CDFHighlight one of the columns in the report and click the Generate
Statistics button to create a PDF or CDF of the results in that
column.
Creating graphs
X vs. YYou can also select multiple columns in the Report Previewer and click on the Show
Graph button to display a graph that will compare the multiple columns chosen.
When choosing the best server, it can be used to see the ranking of all sectors on a particular metric.
Visualizing your results
Creating Sector Display Schemes and Labels
By using the Sector Display Scheme button , you can color-code each sector based on its stats.
There is also a Label button to help you display the per-sector values on the map.
