Project history

01/2014 - 11/2015
Assistant Manager RF-Optimization
Ufone-Etisalat

* 3G-2G Cluster Optimization owner of Islamabad City.
* Conducted multiple sector splits from 65 degree to 35 degree antenna to improve cell load and
user experience.
* Optimization of RAB/RRC/I-RAT HOSR/SHSR/Power Congestion/CE Congestion and other routine
optimization through Physical/Soft Parametric optimization (like Call Admission Control
Thresholds optimization and Power increase to cater power congestion. Improving IRAT HSR with
Parametric optimization like Target Rat, TimetoTrig for verify, PENALTYTIMEFORPHYCHFAIL,CIO
Offset changes.
* Improving UL CE Congestion by triggering 10ms TTI timely from 2ms TTI to reduce CE Congestion.
When remaining CE are limited and cell has high utilization
* Improving Congestion by triggering LDR actions like Best Effort rate reducation,CS IRAT
Handover Triggering ,Code Adjacement and further increasing RAB number for increasing LDR
actions to reduce Congestion on cell including BE Rate reduction, IRAT Handovers.
* Triggering 2D/2F Parameters changes as per requirement to timely or delaying IRAT handovers
along with change in CIO offset for routine optimization changes.
* Conducting New Trials like Fast WCDMA Cell Reselection after CS call ended on 2G due to IRAT,
Ec No improvement by decreasing Power of control channel Parameters like AICH,PICH,PSCH,SSCH
PCH Power and HS-SCCH decrease to increase HS-PDSCH codes Usage of all 15 SF16 codes to
improve Throughput with support of regional NPM Teams in assigned 3G Clusters.
* Improving Drop rate with Parametric/Physical changes like neighbor addition
* Resolution of 3G Complaints in City through routine parametric/Physical optimization.
* Conducted Cluster Acceptance for New 3G Sites Rollout in Islamabad City and getting spot
testing of HSDPA and HSUPA and resolving Call drop issues by Soft/Hard optimization
* Escalating High RTWP due to external Interference issues with Regulator for Jammer removal for
RTWP/KPI Improvement.
* Getting Cell unavailability issues resolved from BSS OPS Team and their continuous follow-up
for urgent resolution.
* Monitoring at same time both 3G-2G KPIs of Islamabad city to ensure timely addressing of any
degradation
* Maintaining External Interference Tracker and POC for conducting Jammer removal activities in
Region and Escalating New Jammer Cases with PTA.
* Providing technical support to team members and resolving customer/Sales Team Complaints.
* Providing explanation on 2G-3G Network KPI to Network performance team for any regional
degradation on Major KPI's.
* Resolving critical issues/VIP Complaints of Islamabad City like Call Muting (Investigating
Number of Mute calls on TRX/Timeslot level and immediately locking TRX Timeslots to resolve
Complaints and taking issue with BSS Team for checking Timeslot Mapping of E1 against TRX
Timeslot.
* Investigating TRX contributing abnormal Radio link failure call drop and getting them locked
till replacement.
* Analyzing single user GCHR traces and PCHR Logs of 3G to identify issues like RAB Failures due
to single UE and other issues faced by customer and their remedial action like necessary
optimization to address weak indoor issue.

01/2012 - 12/2013
Senior Executive Engineer RF
Optimization-Ufone-Etisalat

* Managing 9 Clusters including clusters of Capital City Islamabad for all optimization
activities. Working in coordination with Huawei NPM Teams for all optimization, parametric
changes and physical activities.
* KPI improvement such as DCR, HSR, CSSR.
* Conducting drive test activities using TEMS & Analysis of Radio conditions through TEMS
analyzer
* Performing post DT analysis using Map info to address the coverage and quality issues by
performing possible optimization, tilts adjustment(electrical, mechanical) ,Orientation
redesigning and other parametric changes(Power control changes for improving uplink, downlink
level drops , Shifting traffic to DCS/GSM layer whichever has low Noise floor by Under
laid/Overlaid Handover Margins, Working on Radio link failures per TA in order to reduce DCR
by physical changes to reduce overshoots, Removing discrepancy of TRX Power mismatch,
Improving IASR by shifting SDCCH to BCCH TRX, Analysis of Path balance of TRX, etc.
* Proposing Expansions on cells with increased Blocking(TCH/Mobility/SDCCH) and their follow-up
with concerned department
* Reserving Timeslots channels for Mobility Blocking for highways to avoid call drops,
Increasing SDCCH/8 channels to accommodate SDCCH Blocking, Increasing TCH Timeslots to
accommodate TCH Blocking.
* Monitoring of Stats and analysis of degraded KPIs along with Trx level stats analysis for any
degradation.
* Timely resolution of VIP/Normal Complaints such as call drops/Voice distortion/Echo/Call mute
and coordination with concerned departments for their timely resolution along with conducting
detailed drive test , call testing and conducting on spot optimization activities such as
parametric changes and Physical Audit Tilt Azimuth redesigns
* Maintaining Nationwide External Interference Tracker & Preparing Bi-monthly Reports for higher
management.
* Coordination with Frequency allocation board/Regulatory affairs department for External
interference cases timely escalations and identification of unknown sources for timely
removing jammer devices.
* Responsible for conducting regular drive tests in assigned clusters to maintain a good quality
network.
* Responsible for taking hardware /Persistent TCH Fluctuations /low efficiency TRX performance
with Access Network Operations and follow-up for their timely resolution.

10/2008 - 12/2011
Executive Engineer RF
Planning-Ufone

* Carrying out RF acceptance (Site Integration) of new sites in existing network and all
related issues.
* Preparing Redesign proposals for existing network with the launch of new coverage and
capacity sites.
* Planned Outdoor/Indoor Micro (DAS solution) for big Hospitals, Corporate setups. Along
with link budget designing to cater losses at each distributed antenna and repeater
solutions to optimize the coverage and quality situation.
* Addressing customer complaints and proposing coverage solutions.
* Planned Ufone Phase 7,8,9 and 10 Coverage and capacity sites in rural and urban areas of
North Region.
* Conducted Technical site surveys, Validation of candidates through Asset (Air com tool)
for coverage prediction.
* Preparation of candidate identification reports and Technical site survey reports.
* Tuning of Repeater Donor location (if possible)to reduce the cost of micro deployment in
big cities where we do not have good quality server.
* Routine Optimization of new sites through parametric and physical redesign.
