Learning Mentum Planet for WCDMA

Using the tutorials, you can quickly and easily familiarize yourself with Mentum

Planet. 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. Itconsists of the following elements:

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.

n Mentum Planet menus—provide an alternate way of accessing

Mentum Planet functionality.

n Toolbars—provide an alternate way of accessing Mentum Planet

functionality. Commonly used toolbars include the Main toolbar, theSite 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.

Downloading the tutorial project

The project you will be working with has been pre-configured to illustrate the steps inthe tutorial workflow. You can, however, use it to further explore the features of

Mentum Planet.

CAUTION: In order to complete the tutorial, you require a valid WCDMA license. If

you do not have one, contact Customer Care to obtain a temporary license.

In this lesson, you will download and open the project. You need a valid product ID

number in order to access the Customer Care section of the Mentum website.

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 MapInfoworkspace (.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.

In this lesson, you will browse project settings and associate a workspace with the

project.

To associate a workspace with the project

1 With the WCDMA tutorial project open inMentum Planet, do one of the

following:

n Choose Edit Project Settings.

n Click the Project Settings button on the Network toolbar.

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. Theconditions 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 lesson, you will use the Tabular Editor to associate the On_Air flag to the

Downtown group of sectors.

To identify sectors using flags


2 In the Project Explorer, in the Sites category, expand the Sites node.

3 Double-click the C2750 site.

4 In the tree view, choose sector 4.

5 On the General tab, in the Flags section, choose the On_Air condition

for the Status flag.

6 Repeat Step 4 for sectors 5 and 6.

7 Click OK.

When you click OK, your changes are applied and the dialog box is closed.

When you click Apply, your changes are applied but the dialog box remains

open so that you can make further changes.

All sectors at the site are now tagged as being On_Air. To change the status of

all the sites in the Downtown group in a similar fashion would be very time

consuming. Using the Tabular Editor, you can apply flags and conditions

quickly to a group of sites.

8 Expand the Groups node, and then expand the Shared node.

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 lesson, you will assign a tuned Planet General Model to all sites in the

Downtown_UMTS group.

To assign the tuned model


2 In the Project Explorer, in the Sites category, expand the Groups

node, and expand the Shared node.

3 Right-click the Downtown_UMTS group and open the Tabular Editor.

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

well-crafted traffic maps, you ensure that with your network design, service isavailable 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 lesson, you will create a traffic map using the imported network data.

To create a traffic map1 Open the WCDMA tutorial project if it is not already open.

2 In the Project Explorer, in the Project Data category, right-click the

Traffic Maps node and choose New.

Editing subscribers

The characteristics of subscribers are defined using the nodes in the Subscriber

Settings dialog box. The nodes within the Subscriber Settings dialog box represent

building blocks for subscriber types: Equipment Types, Services, and SubscriberTypes. You can create a diverse mix of subscribers by defining different services,

quality types, and user equipment types and assigning them to subscriber types.

Subscriber types are used with Monte Carlo simulations. Nominal analyses only

require the definition of equipment types.

In this lesson, you will modify subscriber settings to use the traffic map you created

in the previous lesson.

To edit subscribers1 Open the WCDMA tutorial project if it is not already open.

Generating and viewing a network analysis

In Mentum Planet, you can generate an analysis with nothing more than the

equipment type defined in the subscriber settings. This decreases the time required

to prepare for network analysis and results in less time being required to generatethe analysis layers; however, this type of analysis does not generate detailed

subscriber information. The analysis runs only once and generates analysis layers

automatically.

In this lesson, you will learn how to define default layer settings, generate three

layers, and view layers side by side.

To generate a network analysis

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 lesson, 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 aneighbor 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.

In this lesson, you will create a neighbor plan and apply it to the Downtown_UMTS

group.

Creating an Interference Matrix

A histogram interference matrix is generated on-the-fly based on predictions. Each

interference matrix consists of histograms of C/I. There is one C/I histogram for each

server-interferer pair and each histogram represents the distribution of C/I betweena server/interferer pair if they were assigned the same carrier.

In this lesson, you will create a histogram interference matrix.

To create an interference matrix


2 In the Project Explorer, in the RF Tools category, right-click the

Interference Matrices node and choose New Downlink.

3 In the Sector Selectiondialog box, choose the Downtown_UMTS

group, and click OK.

Planning scrambling codes

Using the Scrambling Code Planning tool, you can allocate scrambling codes

automatically based on distance or interference. When you create a scrambling code

plan, each sector is assigned a scrambling code. The scrambling code is made up of agroup code, which is the primary scrambling code, and a secondary code. There are

512 primary scrambling codes available for each carrier. For each primary code, there

are 15 secondary codes.

Before planning scrambling codes, you must define the scrambling code exceptions

and triplets in the network settings.

To plan scrambling codes

1 On the Network toolbar, click the Network Settings button.

2 In the tree view, expand the Network Technologies node, and choose

WCDMA.

3 Click the Scrambling Code Exceptions tab.

4 Scroll to the bottom of the list and enable the check boxes for all codes

in rows 62, 63, and 64.

5 Click the Scrambling Code Triplets tab.

6 Click Create.

7 In the Create Scrambling Code Regions And Triplets, in the Step

box, type 8 and click OK.

8 In the Network Settings dialog box, click OK.

9 Choose Optimization Scrambling Code Planning.

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 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.

n 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 sitecandidate. 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 lesson, you will use the Advanced ASPT option to place sites automatically.

To place sites automatically

1 Choose Optimization Automatic Site Placement.

2 In the Automatic Site Placement dialog box, on the General tab, do

the following:

n Choose the Advanced option.

n In the Region section, choose the Area option and ensure

CoreCluster_Area is selected.

3 Click the Site Templates tab.

Optimizing a single site

When you make changes to sector settings and want to understand the impact these

changes have, you can optimize a single site and view coverage and interference

layers (i.e., the best server signal strength layer and the C/(N+I) layer).

In single site optimization, predictions are generated along radials that span 170

degrees (ignoring the antenna backlobe). Points spread along the radials are then

optimized using the defined criteria and layers are generated.

In this lesson, you will optimize a site.

To optimize a single site


2 In the Project Explorer, in the Sites category, expand the Sites node.

3 Click the Sites node.

A filter box is displayed.

4 In the box, type Site.

Only the newly generated sites are displayed.

5 Expand the Site_1 site.

6 Right-click the WCDMA base station and choose Optimize.

7 In the Sector Selection, accept the default values, and click Select.

8 In the Site Optimization Tool dialog box, on the General tab, enable

the Use A Traffic Map check box and, from the associated list, choose

Ott_Traffic.

9 Click the Optimization tab.

10 Choose the Use Generic Goals option.

11 Clear the Optimize CPICH Ec Coverage check box.
