ATOLL Planning Process‐prediction plots, Neighbor plan and Frequency plan

ATOLL Planning‐‐‐‐‐‐‐

Open ATOLL tool‐‐‐‐‐‐‐‐‐ File ‐‐‐‐‐‐‐‐‐‐ New project‐‐‐‐‐‐‐‐‐ select GPS/GPRS/EGPRS

This is the new project for ur work.

Than go the ‐‐ tool ‐‐‐ options ‐‐‐ than one window will be open than u have to select the UTM zones (universe transverse mercator) Select the coordinate zones as UTM/ZONE 43N for INDIA in projection as shown in following window) than select display format as WGS 84 than u will select the display Lat/Long format for the export. U can change the units also in unit window.

Now go for uploading the maps in the tool. Atoll will support the ASSET format and the file name index will be import in the tool. Or u can import mapinfo TAB files for the vectors.

Go to the file ‐‐ import ‐‐‐‐‐‐‐‐ than select the path of the map file u want upload.

After selecting the path tool will ask u the data type as shown in the following window.

Classification for the data to import‐‐‐‐‐‐‐‐‐

Clutter ‐‐‐‐‐‐ In Clutter classes

Heights (AMSL OF tarrain)‐‐‐‐‐‐ in ALTITUDES or ELEVATION

Vectors ‐‐ in VECTORS

Confidential [MANVENDRA SINGH] [ATOLL process doc]


Places ‐‐‐ In TEXT DATA

Heights of the Clutter (Building heights etc)‐‐‐‐‐ CLUTTER HEIGHTS

As shown in the following Window.

After Importing the Data (Maps, Files ) u can find these data on the map in GEO as shown in the following Window—

Map will be seen as follows .

Go to the GEO‐‐‐‐‐‐‐‐‐‐‐‐ Clutter Classes for the clutter data (Terrain data)

Digital terrain model for elevation (Altitudes) can say AMSL

Text data for places and for any comments

Clutter heights‐‐‐‐‐‐‐ heights of the Clutter like(Buildings)



This above map shows the Clutter heights.

After setting the map datum, Coordinates and importing the map we will import the site within a specific format as in tool.

Shown below‐



U can add the field in as u required by RIGHT CLICK on table and go to table fields as shown in following figure.

You have to specify the name and the size of the column. After making all the columns as required u will import the file in the same columns by browsing the (.txt or .CSV) file format.

‐ if u want to Add some more sites than u can import file again or add with the help of the site creator in the tool bar.



After that u have to import transmitters (Sectors). Go to the DATA‐‐‐‐‐‐‐‐ Transmitter than double click on the transmitter and import the file in the table.

Transmitter will be imported as the above figure.

After importing the transmitters and fixing the antenna type and Propagation model. We will go to the prediction‐‐‐‐‐‐‐‐‐ right click‐‐‐‐‐‐ new A table will open and u fix all the Level criteria As Customer required. After that



Go to the DATA‐‐‐‐‐‐‐ Prediction‐‐‐ right click‐‐‐‐‐‐‐‐‐‐ calculate it will generate the prediction plots . as u required

Than go to new ‐

Than go by Coverage by signal level‐‐‐‐‐‐‐



Fill the above table and go to the prediction again‐‐‐‐‐‐‐‐‐‐‐‐ right click‐‐‐‐‐ calculate.

Than it will show u the prediction plots as u want‐



Again if u want to take interference prediction then again go to the prediction‐‐‐‐‐

Go to DATA‐‐‐ Prediction‐‐‐‐‐‐‐‐ new ‐‐‐ new window STUDY TYPES (One window will open than select in the window coverage by C/I levels)‐‐‐‐‐‐‐‐‐‐‐‐‐ than filled the condition in the given window (Following).

Than filled the condition‐



After filling this window go to the

DATA‐‐‐‐‐‐‐‐‐ Prediction‐‐‐‐‐‐‐‐ Calculate

After this C/I prediction will be plotted on the map as shown in the following map window:‐‐‐‐



Neighbor plan‐‐‐‐‐

After taking Coverage Prediction we can make the neighbor plan for the Active transmitters if the transmitter is not active than it would not come in the calculations. Only the active transmitter come into the picture.

So kindly make sure only those transmitter are active for which u want the Neighbor plan.

NOTE:‐‐ For creating the neighbor plan it is necessary that coverage prediction plot must be calculated.

For making neighbor plan go to‐‐‐‐‐‐‐‐‐

DATA‐‐‐‐‐‐‐‐‐‐‐‐‐‐ Transmitter‐‐‐‐‐‐‐‐‐‐‐‐‐ Neighbor‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐ Automatic Calculation As Shown in the following window:



After This one window will be open fill the neighbor criteria‐

See in the above window



Max inter site distance based on the clutter and the distances between sites. Use 10000m.

Max no of neighbors depend on the frequency band allotted. USE 12 .

Signal level BCCH>‐110dBm

Hand Over Start= 0 dBm

Hand Over end = 6 dBm

% min covered Area=2%

Click on “force Neighbor Symmetry” for both way neighbors.

These above given fields to be filled before calculating the neighbours.

After filling these fields can calculate the neighbor plan.

Than go to the “RUN “ and tool will calculate the neighbors.

After completion of “RUN “ command click on the “COMMIT” button.

After commit u can export the neighbor plan from go to‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐

DATA‐‐‐‐‐‐‐‐ TRANSMITTER‐‐‐‐‐‐‐‐‐‐‐‐ Neighbor‐‐‐‐‐‐‐‐‐‐‐‐‐ Intra Techno Neighbor (Click)

As shown in window:



Than window will open as follows:‐‐‐‐‐‐‐‐‐‐‐‐‐‐

RIGHT CLICK (on window)‐‐‐‐‐‐‐‐‐‐‐ EXPORT ‐‐‐‐‐‐‐‐‐ EXPORT‐‐‐‐‐‐‐‐‐‐‐‐ give the path of the folder where u want to save the neighbor list.



Finally now u can use the neighbor file from the folder where u saved it.

Frequency Plan:‐‐‐‐‐‐‐‐

After completing all above the process, we will make the frequency plan.

First we set the DOMAIN, BAND, group of the frequencies as shown in the following figures.

Go to DATA‐‐‐‐‐‐‐‐‐ TRANSMETERS‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐ Network settings ‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐ Frequencies‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐ domains

‐‐‐‐‐‐‐‐‐‐ Bands

‐‐‐‐‐‐‐‐‐‐ groups



The following window will open for DOMAINS:‐‐‐

The domain in which u r working must be in the domain list showing in the window.

e.g.‐‐‐‐‐

we are working at 1800 domain than the domain 1800 must be in the sheet.

The selecting raw is showing the 1800 domain.



Than go to bands:‐

In this window yours channel must be exist or select yours channels in the above table.



Than go to GROUPS:‐

Select the groups and set the frequencies allotted to the working network and set in the following window.

Put the starting frequency and frequency and step for that.

Now yours frequency setup is ok.

But Before making the frequency plan we will run the interference MATRIX.

For running the INTERFERENCE MATRIX go to: ‐‐‐‐‐‐‐‐‐‐‐

Go to DATA‐‐‐‐‐‐‐‐‐‐‐‐‐ TRANSMITTERS‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐ INTERFERENCE MATRIX‐‐‐‐‐‐‐‐‐‐ CALCILATE

As shown in the given window.



After saving the interference Matrix .

We will run the frequency plan as:‐‐‐‐‐‐‐‐‐‐‐

Go to the DATA‐‐‐‐‐‐‐‐‐‐‐‐ TRANSMITTERS‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐ FREQUENCY PLAN ‐‐‐‐‐‐‐‐‐‐‐ Automatic Allocation (click)



Than window will open as following:‐‐

Select Channels than click next than the window will open as follows:



Than put the separation between channels as follows:

CO‐Transmitter‐‐‐‐all to all ‐‐‐‐‐‐‐‐‐difference‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐2

CO‐Site‐‐‐‐‐‐‐‐‐‐‐‐‐‐all to all‐‐‐‐‐‐‐‐‐‐difference‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐2

Neighbor ‐‐‐‐‐‐‐‐‐‐‐all to all‐‐‐‐‐‐‐‐‐‐difference‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐2

After completing this go to next:‐‐‐‐‐‐‐

Window will open as follows‐‐‐‐



Than click “VALIDATE”

After validation one window will open as follows:‐‐‐‐‐‐‐‐‐

In the following window put the time limit for the frequency planning (depend on How many iterations u want). Monitor continuously the cost and when cost goes stable u can close the iterations mannualy.



After clicking the run window will open as follows:‐‐‐‐‐‐‐‐‐‐‐‐‐

U can monitor the cost of the project continuously with the help of the window.



When cost goes on stable and frequency has been completed.

Than commit the frequency plan. As shown in the following window:‐‐‐‐‐‐

If u want to use this plan than commit this plan and take the export of the Transmitter data .

Channels shown in the transmitter data is ur frequency plan.

If u want to check it on paper than take the export of the run file but not commit till u verified it.




Above is the complete process for prediction, Neighbor plan and Frequency plan.
