Professional Experience

ATEC Wireless, NJ, USA

Apr 2014- Till

Position: Senior RF Engineer

Major activities:

Optimized LTE sites based on coverage RSRP, Quality RSRQ, missing

neighbors and IRAT Handover

using drive test and OSS data.

Improved RSRQ by improving RSRP of dominant cells and reducing coverage

(Interference) of less

dominant sectors through azimuth, antenna Tilt changes and thus

rectified the overshooting sectors

issue.

Analyzed neighbor relation and added missing 4G-4G, 4G-3G, 3G-3G, 3G-

2G,2G-2G

neighbors and deleted the long neighbors using scanner measurement and

OSS.

Analyzed Drive Test log and field collected data for single site

verification and cluster optimization

and prepare the report for KPI optimization.

Monitor cell performance as well as cluster performance of GSM/UMTS/LTE

and analyze to find the

root cause of any drop calls and find out the solution to fix the

problem.

Prepared the RND CIQ and verify the RFDS for the new sites.

Star Link, Bangladesh Jan 2013- Jan

2014

Position: Senior RNO Engineer

Major activities:

Optimized UMTS sites based on coverage RSCP, Quality Ec/Io, Pilot

pollution, missing neighbors,

Soft Handovers and IRAT Handover using drive test data.

Improved Ec/Io (Reduce Pilot Pollution) by improving RSCP of dominant

cells and reducing coverage

(Interference) of less dominant sectors through azimuth, antenna Tilt

changes

and thus rectified the overshooting sectors issue.

Analyzed neighbor relation and added missing 3G-3G, 3G-2G neighbors and

deleted the long

neighbors using scanner measurement and OSS.

Reduced the Inter-RAT Handovers to reduce the time spent in the

compressed mode and hence

improve the UE performance (in terms of call failure problem due to

network related issues).

Analyzed the HSDPA data in terms of CQI, No of HS-DSCH codes, UE

category, the changing

modulation type, the Transport Block size depending upon the modulation

and CQI value, BLER value

Analyzed Drive Test log and field collected data for single site

verification and cluster optimization

and prepare the report for KPI optimization.

RingTech Limited, Bangladesh Nov 2009-

Dec 2012

Position: Senior RF Engineer

Major activities:

Responsible for nominal design for improvement of coverage as well as

capacity of network elements

Defined detailed RF parameter as well as site specific parameters., Performed frequency planning/scrambling codes and prepared site data

fill in XLS form.

Performed network optimization for voice and data traffic to meet the KPIs

of network.

Monitored and analyzed the performance of voice and data network to

improve network quality.

Defined neighbor relation and adding/delete 3G-3G, 3G-2G neighbors as

per requirement.

Responsible for improvement of UE performance by reducing the Inter-RAT

handovers in the

compressed mode.

Analyzed drive test log and data for single site for optimized cluster

as well as KPI.

Team lead for new site selection, site design, RF modernization and new

site acceptance.

Performed RFI to check interference in the network using spectrum

analyzer.

Grameenphone Limited, Bangladesh Nov 2000-

May 2009

Position: Superintendent Engineer, RAN Performance

Major activities:

Monitored and Analyzed daily and weekly cell statistics reports & KPI

trend for accessibility,

retainability, mobility and integrity and take necessary measures to

resolve.

Analyzed cell performance to find out the root cause of SDCCH, PDCCH,

TCH congestion, call drop,

handoff drop.

Analysis drive test log and take necessary measures to improve the bad

situation regarding signal

strength and voice quality.

Responsible to resolve the customer complain regarding the radio

network problem for GSM/UMTS.

Configured, modified of RBS, Cell and TRU in BSC.

Integrated extension cabinet in BSC for increase capacity.

Defined under laid, over laid cell for 900 and 1800 band.
