Lesson 1



Gaia Projects Introduction

The first step in using Gaia is to set up a project and configuration.

A Gaia project relates to all information required by Gaia for the network. This includes:

• Mapping• Site database

• Network files and configuration

• Equipment files

• Properties, such as color profiles, for the analysis layers that you will generate

• System settings, such as power units, height, and distance

At start-up, Gaia needs a minimum of a Mapping folder (containing Heights and Clutter data

inappropriate folders), a Network folder, and Equipment folder. Several other files and folders are

essential requirements for Gaia operation, but Gaia will generate default files in appropriate folders

if data does not already exist.

Once you have defined a project and run analyses, you can create new projects by copying folders

in new locations. In this way, you can make changes while retaining the original data. You can

create one project for one network, or you can create multiple projects for one network in order to

see the effects of changing the network configuration

Lesson 1



For example, you could create a project that includes only sites for a network that covers a

particular geographic area. Then you could create a second project that uses the same network

settings, equipment and models, but that covers a network that is geographically adjacent to the

first one.

• You must retain the file structure within the Mapping, Equipment and Network folders. If you move these folders you must change the file paths in the configuration file to reflect those changes.

Files and folder structure

The majority of the files are stored in three folders;

the Network folder , the Equipment folder , and the

Mapping folder . The location of these folders isdefined in the configuration file.

The configuration filename convention is

<filename>.config. The default filename for the Gaia

configuration file is Gaia.config.

The simplest way to start Gaia is from a shortcut on

the Windows desktop or Start menu. The path to the

configuration file can be specified in the Target field

in the properties of the shortcut, where the syntax

used is <Gaia Executable path> <Configuration file

path>.

Lesson 1



<NetworkFolder>C:\Gaia\GaiaApplication\Gaia\Tunisia\Network\</NetworkFolder>

<EquipFolder>C:\Gaia\GaiaApplication\Gaia\Tunisi

a\Equipment\</EquipFolder>

<MapFolder>C:\Gaia\GaiaApplication\Gaia\Tunisia

\Mapping\</MapFolder>

The paths can be:

• absolute: e.g. C:\Gaia

Application\Gaia\\Tunisia\Network\

• Relative paths are to the folder containing the

Gaia.config file, not the Gaia executable

The configuration file is in XML format and can be edited by any text editor. The path to the 3

main folders used by Gaia are specified amongst the very first entries in the file, and must be

specified correctly e.g.

Lesson 1



Network Folder

The Database tag defines how the data is stored: <Database>MS Access</Database>

Formats supported are:

Tag :

– MS Access – XML – Zipped XML

Mapping Folder

Including the size of the mapping data tiles, the extent limits of the overview map, the projection information, and the land usage index of the values in the clutter data.

The following table gives details of sub-folders contained within the Mapping folder:

3D Objects: – Height – Clutter – Vector – Text – Overview.bmp

Equipment folder

This folder contains all the files relating to the equipment used by the project:

Antenna/ Base Station/ Feeder/ Mobile/ ModelServices

Lesson 1



Workflow for creating a project

To set up a Gaia project, complete the following tasks.

• Step 1: Source appropriate Mapping data (with Heights, Clutter and mapping.config as a

minimum)

• Step 2: Create the Equipment and Network folders

• Step 3: Copy the gaia.config file from the folder containing the Gaia executable

• Step 4: Edit the copy of the gaia.config file to specify the following:

• Database type – Edit the database tag e.g. <Database>MS Access</Database>

• File paths for Network, Equipment and Mapping folders, e.g.

<NetworkFolder>C:\Gaia\GaiaApplication\Gaia\Tunisia\Network\</NetworkFolder>

<EquipFolder>C:\Gaia\GaiaApplication\Gaia\Tunisia\Equipment\</EquipFolder>

<MapFolder>C:\Gaia\GaiaApplication\Gaia\Tunisia\Mapping\</MapFolder>

• Step 5: Save the configuration file with a new name.

• Step 6: Create a desktop shortcut to the Gaia executable.

• Step 7: Specify the path to the configuration file in the desktop shortcut, and save the changes.

• Step 8: Start Gaia from the desktop shortcut.

• Step 9: Gaia should start without prompting for file paths.

• Step 10: To close the project Choose File ♦ Exit.

Lesson 1



Saving Projects

The project settings are separate from the project or network/site data, is saved as the project

configuration and is stored in the configuration file. This includes the map items currently

displayed in the map window, as well as project options settings, such as contour settings, network

settings, WCDMA settings etc.

The configuration is saved by selecting File ♦ Save Configuration.

The project data (network and sites information) is stored separately. Network, equipment,

antennas, models etc are stored in their respective files in the Equipment and Network folders.

The site information is stored in the site database.To save the site data select File ♦ Save Configuration.



Lesson 2



Gaia Project Display Settings and Options Introduction

The left panel contains information about the activesites, site data, and legend. The right panel containsthe map tab, 3D view tab, site data tab, and a number of snap tabs.

Map View

The color of the site/antenna is defined in the Optionswindow located under the Tools menu. Clicking on asite makes that site the selected site, thus displaying itin one of the Site Data tabs.

The status bar at the bottom of Gaia’s window willdisplay the current coordinates of the mouse pointer inthe map, and also the ground height at that point.

The map context menu contains the following functions – Copy – View Path Loss – Signal Strength – Neighbors – Co-Channel – Zoom

– Center On – Measure / Measure Profile – Show/Hide Profile – Snapshot – Visible Items

Lesson 2



• The map tab toolbar contains the following functions:Zoom In

• Zoom Out

• Select

• Pan

• Measure / Measure Profile

• Snap Measure To Site

• Show / Hide Profile

• Map Snapshot

• Visible Items

Lesson 2



Map Profile

The Profile sub-panel of the map displays a cross-section of the terrain. The profile panel is displayeeither by clicking the Show Profile button on the map’s toolbar, or by choosing the option on themap’s context menu.

Drawing the profile is achieved by either:

i) Clicking on the Measure Profile icon on the map toolbar and then clicking on the startand end points.

ii) Selecting Measure Profile from the map’s context menu and then clicking on the startand end points.

While drawing the profile, the end point shows the distance and azimuth from the start point.

Lesson 2



3D view

This tab page provides a real world view of the sites in the network. This can help visualize the

layout of the terrain and give an indication of where is likely to have line of sight to an antenna.

The display of antenna patterns allows a sanity check of whether a reasonable downtilt has been

selected.

The height and direction of the viewpoint (indicated in the panel at top left) can be adjusted by

clicking the mouse at appropriate edge of the view. Alternatively, the view can also be adjusted by

dragging it with the mouse.

Lesson 2



Legend and Overview

The overview map indicates the current location of the Map,or where the viewpoint of the 3D View is. A mouse click onthe overview map will also move the Map or 3D View to the

relevant location.The legend gives a key to the clutter, vectors and layersdisplayed on the map. Each key can be collapsed by clickingon the key title, thus freeing up the legend area for other keys.

Legend

If the Mouse Information checkbox is ticked, when themouse is moved over the map the legend is replaced by a listof the layers on the map and their value at the current mouse position.

Lesson 2



Options

The Options window allows the customization of several aspects of Gaia, including the colors and

size of items displayed on the Map and 3D View. The window is divided over 10 tab pages,

General, Contours, Profile, WCDMA, Frequency, Sites, Mapping, Text, Vectors and Clutter. The

settings defined in the options window can be stored for future sessions by selecting File, SaveConfiguration.

Lesson 3

Workflow for placing sites

(Optional) Analyze Current Network Coverage.

It is usually useful to know what the network

coverage is without the new site.

Step 1: On the map, zoom to the area of interest and

then on the main menu select View♦ GSM

Serving Signal.

Step 2:Click OK and wait as the coverage is

calculated. The Gaia status bar will show the

cell being calculated.

Step 3: In the Map tab page select Visible Items from

the context menu, click on the layer and then

un-tick the box next to the layer.

Step 4Click OK and the coverage will have been

hidden from view.

Lesson 3

Create a new site



Step 1:In the menu select File ♦ New ♦Site

Step 2: In the Sites data window; you now have the choice of creating the site by using the currentlyselected site as a template and click OK.

Step 3:The New Site dialog box opens.

Step 4:To create a new empty site, click OK on the list box and select Empty Site

Step 5:Gaia will show a hexagon at the cursor to indicate to indicate the approximate coverage of the site.(If the site is a copy of a complete site then Gaia will provide an on-the-fly prediction of coverage).

Step 6:The site is now positioned at these coordinates and the ground height is displayed.

Lesson 3

For site copies steps 7 to 14 are not required, make changes only as required.



Step 7:We can now add an Antenna System to the site

Step 8:Select Antenna System from the menu: File ♦ New ♦ Antenna

Step 9:The first Antenna System has been now added on the site

Step 10:Change any parameter such as Antenna Type, Azimuth, Feeder, Model or Tilt

Step 11:For a three-sector site, add two more Antenna Systems on the site: File ♦ New ♦ Antenna

Step 12:Add a new Base Station: File ♦ New ♦ Base station

Step 13:Define the type of equipment and Parent BSC

Step 14:Make the connection between the cells and each Antenna System, by selecting the antenna entry in the cell,and selecting the appropriate antenna in the cell antenna system window cells

Step 15:To check coverage with the new site select View ♦ GSM Serving Signal.

Step 16:To save, select File ♦ Save Sites from the menu, or by clicking on the button on Gaia’s toolbar.

Lesson 1



Antenna Details

The Antenna Details window provides information about the antennas used in the network. It is

accessed:

– Through the Network menu;

– Or by double clicking on an antenna type in the site data panel.

Both the horizontal and vertical antenna pattern can be viewed, as well as a 3D representation of

the two patterns combined.

The viewing angle of the 3D pattern can be adjusted by left-clicking and hold then dragging the

mouse cursor up or down.

Lesson 3



Model Details

The Model Details window provides information about the models used in the network. It is

accessed

– Through the Network menu

– Or by double clicking on antenna system model in the site data panel

A set of model parameters can be defined for each of the frequency bands used by the network.

Lesson 1



Base Station Details

The Base Station Details window provides information about the base station equipment used in

the network. It is accessed

– Through the Network menu

– Or by double clicking on base station equipment in the site data panel

The base station equipment defines how the cells behave and are displayed. Each base station

equipment must be given a technology (GSM, WCDMA etc) and a frequency band designation

from those contained in the network.

Lesson 4



Lesson 4



Traffic Introduction

The traffic functionality is designed to predict the amount of traffic using each cell in the network,

and thus allow the user to assign the correct number of TRX’s to a cell before it experiences any

congestion.

At the heart of the traffic functionality is the traffic grid. This represents a rectangular portion of the network’s service area, and defines the amount of traffic generated at regular points over that

area. A traffic grid is generated from the current cell traffic (or clutter if no network data is

available).

Lesson 4



In the GSM analysis it can be used to predict

the amount of traffic using each cell in the

network, and thus allow the user to assign the

correct number of TRX’s to a cell before it

experiences any congestion.In the WCDMA analysis it can be used to

determine the distribution of services across

the network, and hence the load on the various

parts of the network, the consequence of which

is the interference across the network and also

consequential demand on network resources.

Gaia’s traffic functionality can also be used asan input to pollution table creation, and

consequently influences the results of tools that

are using the pollution table as an input. For

example Automatic Frequency Planning,

Neighbour planning and Scrambling Code

Planning.

Lesson 4



• Step 1: Select area of interest

• Step 2: Tool ♦ Traffic♦ Create Grid ♦

From Clutter,

• Step 3: Add the amount of traffic that is

defined for each clutter type.• Step 4: Click Save will then store the grid,

which will be in an ESRI ASCII grid format.

To view the traffic on the map, tick the check

box at the bottom of the window. The

window is extended to display a preview

panel and the definition of four contours.

The traffic is displayed on the map after it is

saved.

Lesson 4



Scale Grid

This increases the amount of traffic in each pixel of the traffic grid. Clutter is used to scale the grid,

thus allowing different growth rates in various areas of the network. If the network is in the design

stage, no cell traffic data is available. In this case creating a traffic grid from clutter can give a useful

estimate.

GSM Analysis

A GSM analysis calculates the amount of traffic in each cell and the number of TRX’s that are requireto serve that amount of traffic. After the analysis is performed, the site data can then be updated with

the new TRX requirements.

The traffic analysis tool calculates the amount of traffic in each cell and the number of TRX’s that are

required to serve that amount of traffic. The analysis is performed for the GSM cells only.

After choosing the appropriate traffic grid, it is displayed and the user can choose to calculate for the

cells in visible map area or just in the selected area.

After selecting OK, the cell areas are calculated and the amount of traffic they could potentially

capture. The results for each cell are then presented in a new window.

Lesson 1

Th bl i h i d di l h



The table in the window displays the:

• Cell id’s,

• Number of TRX’s currently on the cells

• Number of timeslots capable of carrying

traffic

• Resulting capacity of the cells

• Amount of traffic generated in the cell

• How many timeslots are required

• And resulting the number of TRX’s required

The two buttons “Remove TRX’s” and “Add

TRX’s” update the site data with the

calculated number of TRX’s. Care must be

taken here as the changes are made globally

for all appropriate cells in the table.

The Erlang Table button opens the Erlang B table window.

The Options button opens the Traffic Options window, where it is possible to specify

the required number Timeslots and TRXs for the analysis.

Lesson 5



Lesson 5

Neighbor lists are a f ndamental req irement for all net orks in order to pro ide mobiles ith



Neighbor lists are a fundamental requirement for all networks, in order to provide mobiles with

sufficient information for handover between cells. The Neighbor list is also an input to frequency

planning.

Pollution tables are used in the production of neighbour lists, as well as for frequency plans.

A pollution table defines how much each cell would

interfere with each other cell if they were on the

same frequency. This information is used in the

AFP, to reduce the interference in the network. It is

also used in the creation of the Neighbor relations as

the most polluting cells are the neighbor cells

The Pollution Threshold defines the difference in

received signal strength that must exist in an

individual map pixel before a cell is considered a

polluter to the serving cell.

Once calculated, the table is saved to disk in XML

format.

For every cell, the file lists the:

- Total coverage area;- A list of polluting cells;

- The amount area that would suffer from a

C/I less than the pollution threshold

if the polluting cell had the same

frequency

Lesson 5



Workflow for creating a Pollution Table

• Step 1: Select area of interest

• Step 2: Choose Tools♦Pollution table

• Step 3: Click OK

• Step 4: Save file (*. pollution) to disk

Lesson 5

Neighbor Calculator allows the automatic creation of neighbour definitions. The calculation is based on a

pollution table as the polluting cells are also likely to be the neighbours.

The Neighbor Calculator creates neighbor definitions for each of the cells in the visible map area or in the

selected area. The neighbors are calculated as those cells that pollute the serving cell and are added in the

order of biggest polluter first until the maximum number of neighbors for the base station equipment isachieved.

Workflow for Neighbor list creationTo create neighbor definitions using the Neighbor Calculator:

Step 1: Create a pollution table for the whole area of interest at the

desired frequency band. Save this to disk when prompted.

Step 2: Optionally draw the selection box around the sites that you

want to plan the neighbors for.

Step 3: Choose Tools ♦ Neighbor Calculator.

Step 4: Click on the button next to the Pollution Table text box andopen the pollution table created in step 1.

Step 5: Click OK.

The neighbor definitions can be viewed geographically be choosing

View Neighbors in the Map context menu.

If the ‘Delete current neighbor definitions’ box is ticked, the neighbor lists are calculated from

scratch, otherwise they are just appended to.

File formats supported by Gaia:

XML built into the main Gaia executable file;

XML Schema (.XSD) - writes an XML Schema file which defines the XML file format;

Microsoft Access (.mdb) - writes the site database to a Microsoft Access file;

All Equipment (XML) Exports all the equipment data used in the project to an XML file format (Base

Station, Mobile Equipment, Antennas, Feeders, Services and Models).

Mi ft E l (XLS) S th l i d t

Import - Export



Microsoft Excel (XLS) - Saves the planning data

and each site component is written to a separate

.xls worksheet;

Frequency Plan (.FREQ) - XML format file also

enabling this data to be shared with 3rd party tools;

Google Earth (.KML) - Exports the site data to a

Google Earth KML file format;

MapInfo Sites A MapInfo Interchange Format

(MIF) file is exported containing point data for all of the sites in the network;

The associated MID enabling MapInfo to label thesites or color code them via a thematic map.

Measurement Data



• Support for Surveys and test mobile;

• Measurements are colour coded and plotted as circles onto the map;

• The displayed data can represent a wide variety of measurements, for example signal

strength, quality and timing advance;

• Non-numeric information such as handovers and call drops can be displayed by number

representing the event;

• Survey needs to be converted to a file formatted as comma-separated value (CSV);

• Development if required.

Efficiency



• Typical prediction time – 30 km prediction;

• 100 site (300 sector) analysis – GSM & WCDMA ;

• 300 sector Pollution table;

• 300 sector Frequency plan;

• 300 sector neighbour generation.

Propagation Modelling



• Planet propagation model supported;

• APIs for support of alternative models including microcell models;

• Development if required.

Traffic Planning



• Support for traffic grids;

• Grids can be created from Clutter and from Cell Data;

• GSM traffic analysis: – Traffic capacity calculation – Hardware requirements determination.

• WCDMA : –

spread traffic from traffic grids – sector based traffic loads, – network loads.

Gaia Frequency Planning Tool is compromised of:

Frequency Planning-AFP



• Automatic Frequency planning;

• Manual Frequency planning;

• Pollution Tables;

• The configuration of the AFP (the frequencies and cost factors) can be saved to disk ;

• The file “Frequency Plan.config” is automatically loaded the first time the AFP is started, but other

configurations can be saved and loaded to allow for differences in various areas of the network.

AFP results show:

• List of the transceivers (TRX’s)

Frequency Planning-AFP



• Violation table values

• Co-channel interference values

• Selecting an alternative frequency updates the list of TRX’s, recalculating the violations and

interference.

MFP Mechanical Frequency Planning

Using the MFP is an iterative technique, so at different stages Gaia’s update site data and then the

interference viewed on the map in order to show the process is progressing.

Changing any cell configuration the pollution table needs to be recalculated.

Neighbour Planning



• Neighbor Calculator creates neighbor

definitions for each of the cells in the visible

map;

• Neighbors calculations shows pollution atserving cells;

• Pollution table results are added in the order of

biggest polluter first until the maximum number

of neighbors for the base station equipment is

achieved;

• Create pollution table for the area of interest at

the desired frequency band;

• Different neighbors scenarios are possible,depends of the user preferences;

• Displaying maximum number of neighbors;

• View neighbor show cell data in new neighbors

tab;

• Analyses neighbors statistics for each cell.

Neighbour Planning



Multi add of the neighbors:

5. Graphically Add Neighbor On Map;

6. Add Neighbor Cell Id;

3G simulator (R99 & HSPA) and analysis of results



To create a WCDMA Monte Carlo analysis:

• Easy pre setting Map window for WCDMA

analysis;

• Run Monte Carlo simulation window from

the tools menu;

• Desired naming convention is available for

each analysis;

• Availability to specify desired analysis

resolution and snapshots to run;

• Automatically update of Traffic Power %'and 'Target. Noise Rise dB' values form

MC simulation;

• Ability to specify traffic grid scaling for eachservice included within analysis.

Generating analysis of different layers:




• Specific and desired services;

• Curriers;

• Downlink and Uplink layers for every combination of carrier, service and selected downlink or

uplink layer.

The WCDMA Monte Carlo results are presented:

S




• Statistically;

• Graphically.

•The WCDMA Monte Carlo Results dialog will browse all completed analyses, select layers to display and

view statistical results;

•CPICH and Handover layers are only generated for the service that was specified when the Monte Carlo

analysis was generated.

3G layers



3G layers



Intersystem Planning



• Multiple technologies supported in same project and session;

• Inter RAB Neighbour planning is supported.

AFP/ACP integrated or interfaces



• Open APIs provide simple support for third party products;

• AFPs;

• ACPs;

• Propagation Models including microcell.
