INTRODUCTION Cellopt DataExchange is a powerful tool that allows you to interface Cellopt AFP with major cell planning tools, in order to export the required input data for the frequency planning process and importing plans generated by Cellopt AFP back to the cellplanning tool.

NEW

IN VERSION

2.4

Cellopt Data Exchange version 2.4 includes these features: 

NEW

Support for Forsk Atoll v.3.1.0 (Single- and MultiRAT projects). Note that backward compatibility with older Atoll versions cannot be guaranteed.

IN VERSION

2.3.1

Cellopt Data Exchange version 2.3.1 includes these features: 

Support for Forsk Atoll v.2.8.2



Cellopt License is no longer required

NEW

IN VERSION

2.3

Cellopt DataExchange version 2.3 includes these features: 

Unicode Support Support for Unicode Characters in site and sector names.

NEW

IN VERSION

2.2

Cellopt DataExchange version 2.2 includes these features:



Direct Use of Predictions Earlier versions of DataExchange used an indirect method to calculate signal values. Path loss and inclination were calculated separately by Atoll and

5

Actix Cellopt DataExchange Getting Started Guide 2.4 - Forsk Atoll

combined at a later stage. This allowed support for products that are now defunct. In DataExchange 2.2, signal values are extracted directly from the predictions. This simplification works sufficiently well for use with Cellopt AFP. This solves the following issues: - User-defined prediction models were not being used. - Predictions in the user project were invalid at the end of DataExchange runs.



Citrix Access Restrictions Earlier versions of DataExchange set Atoll parameters by writing into the atoll.ini file. This is no longer necessary, allowing DataExchange to run on a Citrix server where there is no ‘write’ access to this file. This solves the following issues: - DataExchange wrote to atoll.ini. - Error when Atoll closes down.

NEW

IN VERSION

2.1

Cellopt DataExchange version 2.1 included these features:



Atoll 2.4.1 support Cellopt DataExchange 2.1 now supports interaction with version 2.4.1 of Forsk Atoll as well as version 2.2.2 (introduced in DE version 2.0).



BSIC restrictions BSIC restrictions per sector made in Atoll are now exported to Cellopt AFP. The restrictions are set as forbidden BSIC in the AFP project.

INTRODUCED

IN VER SION

2.0

Cellopt DataExchange version 2.0 included these features:



Forsk Atoll integration Cellopt DataExchange 2.0 integrates to the Forsk Atoll planning tool. It is possible to generate a Cellopt AFP project based on the data in Atoll as well as import plan assignments (frequencies, HSN & MAIO and BSIC) back to Atoll. The computation zone is used to select the network parts to be exported to Cellopt AFP.



Cellopt AFP project export Cellopt DataExchange generates a GSM Cellopt AFP project file that is imported into Cellopt AFP. Network properties (sites, sectors and radios), spectrum assignments and frequency hopping settings and the Atollgenerated neighbour list are exported.



Interference list generation An interference list based on the planning tool predictions can be generated and included in Cellopt AFP project export. Interference list options, e.g. the C/I and C/A thresholds that define interference may be specified in the client.



Neighbour list generation A neighbour list based on the planning tool predictions may be generated and included in Cellopt AFP project export. Neighbour list options may be.



Cellopt AFP plan import The assignments (frequencies, BSIC and HSN & MAIO) optimized in Cellopt AFP can be imported back into Atoll.



Atoll focus and computation zones The sites/sectors/radios part of the focus zone are exported as the selected radios (and marked with layer Selected in the Import category) in Cellopt AFP which may be changed by the optimizer. In addition, a special category,

8

Actix Cellopt DataExchange Getting Started Guide 2.4 - Forsk Atoll

Zone, is used to mark radios belonging to the focus and computation zone, to allow loading additional selections (which will then change the layers of the “Import” category).



Atoll frozen modelling The frozen attributes in Atoll (sectors, frequencies, BSIC and HSN) are included in the Cellopt AFP project in a category called Frozen. The layers of this category indicate the property that is frozen. This is important, as Cellopt AFP cannot prevent a reassignment of a frozen element. The frozen assignment can be maintained by simply unselecting the site/sector/radio.



Atoll channel type modelling The channel type information is maintained in a category called Channel Type, included in the exported Cellopt AFP project. Possible layers of this category are: BCCH, TCH and TCH_Inner depending on what are used in Atoll.



Atoll HCS modelling The HCS layer information in Atoll (if available) is exported to a category called HCS.

GETTING STARTED

WITH

CELLOPT DATAEXCHANGE

10

Actix Cellopt DataExchange Getting Started Guide 2.4 - Forsk Atoll

INSTALL ING CELLOPT DATAEXCH ANGE 1. If you have not already done so, download the Cellopt DataExchange .zip file. 2. Extract the contents of the .zip file to a temporary directory. 3. From this directory, run the setup.exe program. The setup program may first run installers for the Microsoft .NET Framework 2.0 and/or the Visual C++ Runtime libraries, before installing Cellopt DataExchange itself. 4. Follow the instructions given by these installers.

CONFIGURING FORSK A TOLL 1. Launch Atoll. 2. Open the project that you want to work with. 3. Define the focus and computation zones. The focus zone contains the sectors that you want Cellopt AFP to optimize. For Cellopt DataExchange 2.3, your computation zone should completely encompass the region defined by the signals originating from the sectors within the focus zone. This is useful because all statistics in Atoll are based on the focus zone, while Cellopt bases its statistics on a regular bounding box containing the computation zone. 4. Make sure that all the predictions are valid and current. To do this, right-click on the "Transmitters" branch and open the "Properties" dialog. The table lists the status of the prediction files in the project. To make sure that there are no invalid propagation entries listed, press the Statistics button. If the number of transmitters to be recomputed is not zero, then the prediction

11

Actix Cellopt DataExchange Getting Started Guide 2.4 - Forsk Atoll

needs to be recalculated. Note that inactive sectors will have missing predictions - this is not a problem.

12

Actix Cellopt DataExchange Getting Started Guide 2.4 - Forsk Atoll

5. Make sure that there is at least one unlocked prediction (for example, a strongest server prediction) in the "Predictions" folder. If there are no unlocked entries in the "Predictions" branch, Atoll will not generate any data when it is instructed to do so by Cellopt.

Unlocked prediction

6. Check that Atoll correctly generates the prediction when you click the "Calculate" toolbar icon or press . 7. Cellopt can only import raster traffic based on environments. If you want to use raster traffic data with Cellopt, you need to export the traffic using the BIL format. This is done by going to the traffic data and right-clicking on the environment maps you are interested in. If you export the traffic data to a BIL file, you will need to re-save the configuration file as explained in the next section.

13

Actix Cellopt DataExchange Getting Started Guide 2.4 - Forsk Atoll

8. Export the configuration to a file. This file will be used by Cellopt to read the configuration data. The configuration file must use the same name as the Atoll project, and be in the same directory as that project. For example, for project file "C:\Atoll Projects\Demo.atl", export the configuration to the file "C:\Atoll Projects\Demo.cfg". This allows Cellopt to pick up information about the traffic grids that is not available through the API supplied by Forsk. To save the file, from Atoll, select Tools > User configuration > Export and then select the information you want to export:

Specify a signal strength Cover threshold value in dBm. Cellopt DataExchange includes a geographic bin in the calculations if the signal is greater than the sensitivity value.

Actix Cellopt DataExchange Getting Started Guide 2.4 - Forsk Atoll

I nte r fe re nc e lis t opt i ons 1. Include adjacent channel statistics between sectors. Check this to calculate adjacent channel statistics (only shown for iDEN networks).

2. Specify a C/I target value in dB. 3. Specify an Adjacent channel offset (in dB) – this is a difference between adjacent channel frequencies. 4. Specify a Standard deviation (in dB). This is used to provide a smoothing function to the probability of interference, which is useful in modelling variations in signal strength around the mean predicted for any area inside a geographic bin, as well as to account for any inaccuracies in the prediction model. Cellopt DataExchange uses the standard deviation to create a range of interference probabilities around the target C/I. As a guideline, the standard deviation of your prediction model is a reasonable value to use for this purpose. For example, given a target C/I of 12 dB and a standard deviation of 8 dB, DataExchange would assign a small probability of interference at a C/I of 20 dB, which increases to 100% at a C/I of 4 dB.

28

Actix Cellopt DataExchange Getting Started Guide 2.4 - Forsk Atoll

By contrast, a standard deviation of 0 dB would result in a 100% probability of interference at 12 dB or lower, and a 0% probability of interference at a C/I of 13 dB or higher. 5. Specify a Noise value (in dBm) – this is the amount of thermal and external interference present within the network. 6. Specify a Global bias value (in dB) - this is the amount that a second signal must be in order to be classified as a second server. Cr e at e Cel l op t Nei gh b ou r l is t 1. Create Cellopt neighbour list – check this box to export a Celloptgenerated neighbour list. Note that this list will be in addition to the Atollgenerated neighbour list, if available.

2. Handover hysteresis start – this is the minimum signal margin (in dB) that a sector can have, and be considered as a neighbour sector rather than an interferer. 3. Handover hysteresis end – this is the maximum signal margin (in dB) that a sector can have, and be considered as a neighbour sector. For example, if you set the handover hysteresis start to 3 dB and the hysteresis end to 12 dB, then all signals in the 3 to -12 dB range are considered as neighbours. In this example, signals between 0 and 3 dB are assumed to be interferers. Signals greater than -12 dB are not neighbours. 4. Once you are satisfied with the settings on this page, click Next to proceed to the Start Export page.
