Mentum Planet Walkthrough
Mentum Planet Walkthrough topics
Mentum Planet Walkthrough topics are intended to provide you with some understanding of
the basic concepts of network modeling using Mentum Planet in order for you to quickly and
easily familiarize yourself with the software. The project you will be working with has been
pre-configured to illustrate the steps in the workflow. You can, however, use it to further
explore the features of Mentum Planet. Ensure you have installed Mentum Planet on your
computer and set aside approximately two hours to complete all the walkthrough topics.
While no prior knowledge of Mentum Planet is required to complete the walthrough, it is
assumed that you know how to access ToolTips and shortcut menus, move and copy objects,
select multiple objects using the Shift or Ctrl key, resize dialog boxes, expand and collapse
folder trees. It is also assumed that you are using the standard Windows desktop.
The Mentum Planet interface has been designed to provide easy access to the main
workflows you follow as you design and optimize a wireless network. It consists of the
following elements:
n
n
n
Project Explorer—provides quick and easy access to Mentum Planet functionality from
a central location. By default, it is docked to the left but you can customize the location
of the Project Explorer to suit your needs.
Mentum Planet menus—provide an alternate way of accessing Mentum Planet
functionality.
Toolbars—provide an alternate way of accessing Mentum Planet functionality.
Commonly used toolbars include the Main toolbar, the Site toolbar, the Analysis
toolbar, and the Network toolbar.
A Mentum Planet project contains all of the information pertaining to a particular wireless
network. It consists of a collection of files and folders. Each project has a project (.planet)
file that defines the project structure and references the associated data (planet.dat) file. To
begin the walkthrough, you must first download the dataset.
Note: In order to complete the walthrough, you require a valid license for the
technology you are using. A walkthrough is available for LTE, WiMAX, and WCDMA. If you
do not have the appropriate license, contact Customer Support to obtain a temporary
license.

Mentum Planet Walkthrough
Defining project settings
Project settings encompass all the parameters that determine how a project is displayed and
what it contains. They define the geodata to be used, the coordinate system to adhere to as
well as the workspace associated with it. It is the MapInfo workspace (.wor) file that stores
the list of all tables, windows, and settings you are using. Using a workspace and the
autosave feature, you can ensure a project looks exactly the same every time you open it.
Workspaces enable you to work more efficiently and eliminate the need to open map layers
individually each time you view a project.
You can also define custom data definitions that can be used to add custom attributes to
project entities such as base stations, sites, sectors, repeaters, and antennas. This data is,
however, stored locally and cannot be shared using Data Manager.
In this walkthrough, you will browse project settings and associate a workspace with the
project.
Note: Before beginning the walkthrough, download the dataset. See "Mentum Planet
Walkthrough topics" on page 3 It is best to complete walkthrough topics in the order they

Placing sites automatically
Using the Automatic Site Placement Tool (ASPT), you can place sites in a defined area
quickly and easily. There are two modes that you can use with the ASPT:
n
n
Basic—the tool generates hexagons based on the criteria you define and places a site
at the center of each hexagon using either the default site configuration or the site
template you specify. If you are using a clutter file, you can exclude clutter classes
such that no sites will be placed within them.
Advanced —the tool generates complex shapes based on the planning strategy you
choose and the criteria you define (including clutter-specific criteria) and places a site
at the center of the shape using the site template you specify. Each site is given a level
of priority that determines whether it becomes a possible site candidate. In Advanced
mode, you can use a traffic map in order to generate more accurate shapes. In
addition, you can use existing and candidate sites in the site placement process.
In this walkthrough, you will use the Advanced ASPT option to place sites automatically.
Note: Before beginning the walkthrough, download the dataset. See "Mentum Planet

Assigning a propagation model
In order to model a network that is as close to the real-world network as possible, you need
to calibrate the propagation model using survey measurements.
Once you have calibrated the model, you can associate the model to other sites that share
the same type of environment, provided that the model is not overly dependent on
calibrations (empirical models generally rely heavily on calibrations).
In this walkthrough, you will assign a tuned Planet General Model to all sites in the Core
group.

Identifying sectors using flags
Flags are properties that you can use to identify sectors as having certain characteristics
(conditions). You can create multiple flags, and each flag can have multiple conditions, but
you can assign only one condition per flag to a sector. The conditions of a flag should be a
set of related but mutually exclusive values (e.g., you could have a flag called "Status" with
conditions called "On-Air", "Under Construction", "Offline").
In this walkthrough, you will use the Tabular Editor to associate the On_Air flag to the
Downtown group of sectors.
Note: Before beginning the walkthrough, download the dataset. See "Mentum Planet
Walkthrough topics" on page 3 It is best to complete walkthrough topics in the order they
are presented.

Creating a traffic map
Traffic maps provide data about the geographical distribution of subscriber traffic in a
network and are key to creating an accurate model of network performance. By using wellcrafted traffic maps, you ensure that with your network design, service is available in the
areas where it is most needed.
You can base the traffic map on various data sources including regions, vectors, classified
grid, or network data. And, in order to ensure the traffic map is as realistic as possible, you
can define a weighting value to the input data that represents how much traffic to model.
In this walkthrough, you will create a traffic map using the imported network data.
Note: Before beginning the walkthrough, download the dataset. See "Mentum Planet

Generating a Monte Carlo simulation
A Monte Carlo analysis uses Monte Carlo simulation techniques to determine the
characteristics of the network over repeated runs. A run consists of the distribution of
random numbers of subscribers throughout the simulation area in a random pattern, and an
analysis of the uplink and downlink. On the last run, operating points and discrete subscriber
information are generated. Once the runs are completed, you can view the results including
detailed reports, discrete subscriber information, and an optional service layer generated
after the Monte Carlo simulation. Monte Carlo simulation results provide you with detailed
sector loadings that you can apply to cells. You could then create a network analysis in order
to generate accurate network analysis layers based on the Monte Carlo simulation results.
In this walkthrough, you will create a Monte Carlo simulation and review the Sector/Carrier
report.

Creating and applying neighbor plans
In order to design a wireless network where users can move between sectors smoothly
with no interruption of service, you need to understand how sites influence each other and
how they can better interact with each other. To do this, you create a neighbor plan that
encompasses sector neighbor lists and using this information, you can determine the best
handover strategy for the network and make appropriate decisions about network design.
Neighbor relationship management in Mentum Planet encompasses the following basic
elements: neighbor lists and black lists, which are defined at the sector level, and neighbor
plans, which are defined at the network level.

Analyzing fixed subscribers
A fixed subscriber analysis analyzes network performance at discrete subscriber locations
defined in the fixed subscriber table. If required, for each subscriber, you can define a
unique configuration (e.g., locations, UE with integrated antenna, or UE with directional
antenna mounted at roof top). For example, at the same location, you may have multiple
subscribers but each subscriber is at a different height. This is a configuration that would be
required if subscribers, for example, in the same apartment building are located on a
different floor (i.e., at a different level).
For every subscriber, the analysis predicts the signal strengths at the location, and
determines the best parent server and the potential second best server. The downlink and
uplink performance, in terms of best available modulation, maximum achievable data rate,
coverage probability, margins, etc. are then analyzed. The analysis results of each
subscriber are stored in the fixed subscriber table.
In this walkthrough, you will analyze fixed subscribers.
Note: Before beginning the walkthrough, download the dataset. See "Mentum Planet
