Objective

• Know How To Drive Test Initial Tuning• Know Software for Initial Tuning : mcom ,

katherein scala, static analyzer• Know Initial Tuning Report

INITIAL TUNING

Preparation• Software :

- Tems Investigation 4- Map Info- MCOM- Kathrein Scala (additional)- Static Analyzer (additional)

• Tools :- 2 Tems MS (T68)- GPS- Laptop- Camera- Other ( inverter, rigger tools)

Preparation

• Basic Knowledge :– GSM Generally– Drive Test (plus Scanning Freq n Time Slot Check)

• Data :– Map– CDD + MO (dump + process) - daily Update– Kathrein Analog– STS database – daily update (additional)

About MCOM• Create New Project• Import new mcom site• Import CDD dump (neigbor+carrier) – CDD Should be updated daily• Check BCCH and interference• Check neighbor• MCOM workspace will be used as MapInfo workspace

About MCOM• Check BCCH and Interference sample

About MCOM• Check Neighboring sample

About Kathrein Scala & Katalog• Know antenna type and specification• Know how antenna downtilt affects coverage area in Kathrein Scala

About Static Analyzer• Check Performance Site – Basic KPI Statistic (drop rate, SDCCH success

rate, handover success rate)• Database Should be Updated Daily

About Static Analyzer• Sample 1 : TCH Drop Rate

BAD GOOD

About Static Analyzer• Sample 1 : SDCCH Success Rate

BAD GOOD

About Static Analyzer• Sample 1 : Hand Over Success Rate

BAD GOOD

About CDD n MO• Cell Design Data (contain data such as frequency, neighboring, etc)• Management Object (contain data such as site config, alarm, etc)

Initial Tuning Activity• Preparation (tools and site data)• Site + Neighbors Audit and Change (Coordinate, tilt, orientation/bearing,

panorama, antenna type, height, area)• Drive Test

Tuning Site Band 900: First : MS1 = Dedicated Lock 900, MS2 : Idle Locked to BCCH, Second : MS1 = Dedicated Normal, MS2 : Idle Locked to BCCH,TS Check, Freq ScanningTuning Site Band 1800:MS1 = Dedicated Normal, MS2 : Idle Locked to BCCH,TS Check, Freq Scanning

• Report…..

TimeSlot Check and Freq Scan

• How?5 minutes for Freq Scan each cells / sector

15 minutes for Time Slot Check each cells / sector using Tems Layer 3 Control

• Telkomsel Freq Scan : 50-88 (900 band)576 – 820 (1800 band)

Target

• Target Drive Test– No Blocked Call, No HandOver Fail, No Dropped Call– Good CI plot– Rx Lev, Rx Qual, SQI– Idle Rx Lev vs TCP Plot

• Target KPI Statistik- DCR, HOSR, SDSUCC

Problems• Site Down (Power?, Transmisi?) -- call Tuning Engineer / Coordinator• Site On but not Servin -- call Tuning Engineer / Coordinator• Cannot making call -- call Tuning Engineer / Coordinator• Cannot HO (Neighbor Relation not created yet) – call Tuning Engineer / Coordinator• HO Failure (Interference, Co BSIC, Congestion), need parameter / frequency

changing -- call Tuning Engineer / Coordinator• Pingpong HO (Cross feeder, orientation problem) -- call Tuning Engineer /

Coordinator• Difficult HO DCS (Layer 6) to GSM (Layer 7) -- call Tuning Engineer / Coordinator• Bad Quality (Interference), need frequency changing -- call Tuning Engineer /

Coordinator.• Low signal strength (wrong tilt / orientation)• Installation Problem (cross feeder, antenna tilt n orientation), take any logfiles /

photos -- call Tuning Engineer / Coordinator• Coordinate problem, different between planned coordinate and actual coordinate --

need any changing -- call Tuning Engineer / Coordinator• Drive Test Route Problem• Community Problem, Cannot access to site – call Tuning Engineer / Coordinator• Dll…

Making Report• Export Logfiles• KPI calculation (optional using macro)• Plot in Map Info• Others……….
