GSM uses concept of cellsOne cell covers small part of networkNetwork has many cellsFrequency used in one cell can be usedin another cells

This is known as Frequency Re-use

Co-Channel ( Re-use ) Cells







Co - Channel interference

C Ic 9 dbInterference on a channel caused by another cellmobileusing the same frequencyCIc is the measure of co-channel interferenceGSM specifies the CIc threshold of 9dB for a service quality

of 04 BER on Type II bits9db also includes 2db implementation margin9db is decided considering the implementation of SFHWithout SFH the preferred threshold is 12 dB

CIc

CausesDistant Cells due to tight frequency re-use patternsDistant Cells due to errors in frequency planningMulitpath from Distant cells( strong reflector Water)CIc will degrade the EcNo so if Noise floor itself is high then evena high value of CIc can deteriorate quality

Adjacent Channel Interference

GSM receivers are designed for an Adjacent Channel Suppression ofminimum 18db at an offset of 200 Khz 50db at 400 Khz and 58db at 600Khz






ACS = 18db amp Cc = 9dbThis means if Ia is 9db above C then with 18db ACS it equals CIc

Distant Cells due to errors in frequency planningMulitpath from Distant cells( strong reflector Water)Improper Receiver filters ( low ACS )CIa will degrade the EcNo so if Noise floor itself is high then

even a low value of CIa can deteriorate quality

QA Drive Process Suggestion

-Routes should be predefined

-Test plans should be preset

-Drive Duration and Time of Day should be preplanned- Peak Traffic Hours should be used for QA tests

-Markers and Notes should be used

-Data should be preferably binned

-Use Analysis Reporter to get quick shot QA performance Report

-Thresholds should be standardized

Short Calls-Reliable CSR

-Non-Reliable Drop

Long Calls

- Non-Reliable CSR

- Reliable Drop

bullAverage User Call time should be taken ( 2mins 15 secs off)

bullCSR is more reliable on cumulative traffic basis hence focus should be more onDrop calls

bullRecommended to do Quality Drive separately or use two phones and then usecombined statistics generation

bullHandover Performance

Points to be Noted

-QA Tests and Results Model is very much local dependent

-Only certain industry international procedures and parameters can be usedas referenceWe donrsquot recommend the ldquoCtrl C amp Ctrl Vrdquo approach

-Localization of the QA procedures has to be done through model tuning

-This needs some significant hours of work at country level might be worthconsidering a consultant for this

Pl i V ifi i i h QA D i





Planning Verification with QA Drive

-It is an incorrect norm to use Planning Tools for Post Data Analysis

-Some Planning tools support import of drive test data and also do modellingbased on this data

-There are several variants in drive test data like Power Control improperhandover parameters settings etc which can hamper this modelling

-Planning Data efficiency can be achieved through modelling the Planning Toolby using Test Transmission exercises

-Significant Variance in Planning Data vs measured data can be identified by

comparing the results

-Reverting to Planning Tool should not be a part of QA team work it is theoptimization team role to use the QA data and see where the flaw is

QA Drive Best Practices





QA Drive Best PracticesData Preservation

-Centralization of Database and Reports

- All data collected after filtering the non useful file shouldbe saved on a Server which has proper identification matrix

State

- City- Zone1- Zone n

- Jan05

- helliphellip- Dec 05

- Same Structure should be repeated for Reports also- At least 18 months of data should be preferred

- No need to preserve Troubleshooting Data only QA is enough

-Third Party Browsing Software can be developed to do Report Management ApplicationsAgilent can help with this

-A Basic Server Webbased Browsing with MYSQL Queries can be easily developed within 50KUSD We can help BSNL in identifying the Vendor and also help the feature requirements specs






QStandardizing Nomenclature and Terminologies

- Log files and Report names should all be standardized- Even the folder structure on local PCrsquos should be standardized

Example

CDrivetest sd5 - Log Files

CDrivetest planfiles ndash spf Plan Files

CDrivetest Reports

Logfile names should be use default Agilent names which has date and time butuse separate sub folders for location or if u desire to put some separate identify put atthe end of the file like 06-09-2004_02-56-22 PM_ GPRS Web testSD5

Whenever a correct report is generated use SAVE AS to save it in the report folder It is good

create a folder matrix in advance and standardize that country wide so if you for servermanagement it becomes easy

bullOptimization takes data from several sources

- Power Settings Antenna Tilts Frequency Parameters

bullCoverage Holes- Adequate Coverage to Hot Spots Indoor

bullCapacity Balancing

- Cell Configuration Power Antenna

bullFeature Implementation

Optimization Challenges





Optimization in most cases is of two type

Overall Done over a wide geographySelected Done over a selected problem areabullFor Overall Drive Test is done over a larger area for verification

bullFor Selected Drive Test is done over the selected area whereoptimization work was done but the problems (specific to frequencyrelated) gets shifted to other areas

bullPre Optimization Drive Test Data is generally derived from QA Drive Testitself

bullPost Optimization Drive Test can also be undertaken by QA team in aselected zone

What keeps RF engineering and operations





Increase Revenuesand Drive Down Costs

What keeps RF engineering and operationsmanagers up at nightbull How can I maximize the return on my test

equipment investment required to install ampmaintain my 2G25G3G networks

bull How do I quickly rollout complex next-generation data networks and ensureoptimum performance

bull How can I optimize my existing and new253G networks without limited resources

bull How do I accelerate the migration of mynetwork to a new technology

Declining capital requires ways to increase revenues reduce OpEx and improve RO

What makes a RF engineering and operations
