Open a new Project
•
Define the Co-ordinate system of the map
(WGS84/UTM zone zone 44) in the Tools/Options •
Import the Digital map File/Import/Select the map select index file of Clutter and import it
Change the colors of the clutter for different clutters for easy identification File/Import/Select the map select index file of Heights and import it for getting the Digital Terrain
File/Import/Select the map select index file of Vectors and import it Change the colors of the Vectors for different Vectors for easy identification
Planning tool •
Import the Antennas
•
Import the Propagation Models
•
In the Predictions Right click and create new coverage by signal level Change the values and colors in the Legend for easy identification Right click and create new coverage by C/I level
Change the values and colors in the Legend for easy identification Right click and create new coverage by Transmitters •
Create a template for 3sector site Create a template for 1sector site by giving the filling the required information
Creating sites •
•
•
•
•
Select the icon adjacent to Site template and click in the map. Change the Latitude and Longitude. Give the site name. Double click on the sector and changes in the sector may be incorporated. Create the sites as above Run for Coverage by signal to get the coverage maps of all sites. Run for Coverage by Transmitter to get the coverage maps Cell wise.
Frequency Plan •
•
•
•
•
Group the Total frequencies in to TWO groups for BCCH and TCH allotment. Double click on the sector and assign the BCCH frequencies. Run for signal by coverage by C/I to get the interference levels of all sites. Change the BCCH accordingly to get better C/I Assign BSIC
Frequency Plan •
Subgroup the TCH frequencies in to 6 groups.
•
Group 1
64,111,118
•
Group 2
80, 112,119
•
Group 3
81,113,120
•
Group 4
82, 115, 122
•
Group 5
87, 116, 123
•
Group 6
88, 117, 124
•
Assign each group to different cells for assigning the TCH Frequencies
•

•
Assign HSN for each site/Cell
•
Assign BSIC for each sector

Defining Coordinate system •
•
Click on Tools/ Options Select the Coordinate system in the Projections and Display
Propagation Model Select the propagation Model in the Explorer window. In the Pop down menu select the type of propagation model to be used and double click it to get the property window. Change the values of K1, K2 etc and clutter losses to get the propagation model

Import
•
Browse the Map folder
•
Select the Clutter and import clutter data
•
•
Select the Heights and import Terrain data Select the Vectors and import Vector data
Import the digital maps •
In Explorer window Select and Right click the Clutter classes and Select Centre in the Map to view the Map
•
Double click the clutter classes and change the colors of different clutter classes for easy identification
Import the digital maps •
Open POP Down menu in Vectors and Select each vector , Right click it and select the color and select the style for easy identification of each vector
Importing the Antennas •
Import all the Antenna models used in the field by importing individually each Antenna file supplied by the Manufacturer
Creating a Site Template •
In the Template POP Down menu select the required Template and select the Manage template then Station Template Properties window will appear. Select the properties then Properties window will appear. Change the properties in the window as per the model of the site. Click OK for creating Template. Select the number of templates as required.
Creating a Site Template
Creating Sites and Cells (Transmitters) •
Select the Site Icon and click it in the Map window for crating the site. Double click the site and enter the Latitude and Longitudes of the site. Enter the site name. The site will be moved to the required location.
Creating Sites and Cells (Transmitters) •
Select the Transmitter/ Cell and double click it. Cell property dialog box will appear. Click the different tabs available in the box and changes may be made by changing the required values. For changing the height, azimuth, tilt, Power, Propagation model, calculation radius, BCCH, TCH Freq, BSIC and more of sector may be changed by modifying.
Creating Sites and Cells (Transmitters) •
Double click on the sites in explorer window to get sites list. The content can be copied and pasted into EXCLE sheet. The sites can also be created by copying the site data in the same format from EXCEL sheet.
Creating Sites and Cells (Transmitters) •
Similarly double click on the Transmitters in explorer window to get Transmitter list. The content can be copied and pasted into EXCLE sheet. The Transmitters can also be created by copying the Transmitters data in the same format from EXCEL sheet.
Coverage predictions •
For creating the Coverage predictions, right click the predictions. Study type box will appear. Click on Coverage by signal level and change the intervals of the coverage levels. Change the colors for easy indications. Similarly Click on Coverage by Transmitter. Change the colors for easy indications. Click on Coverage by C/I level and change the intervals of the levels for Interference levels. Change the colors for easy indications.
