Professional Experience:

RF Engineer with Engineering Network International Inc. (Nov2010 - Present)

Responsibilities:

• Currently involved in Pre-launch Optimization (AT&T) for UMTS 1 st & 2nd Carrier in MI/MN

market

• Responsibilities include preparing site lists, initial neighbor list; neighbor lists verification,

creating cellrefs, mapper and drive routes verifications/modifications using MapInfo.

• Analyze cluster drive data and market drive data using Actix, MapInfo.

• Preparing Neighbor List for Intra, Inter, IRAT, IRAT Core & Border & Assigning Priorities.

• In call analysis for call drops (CS and PS), Pilot pollution analysis, parameter configuration,

scrambling code offset changes, IRAT neighbor analysis and UMTS neighbor analysis.

• RF Coverage optimization using antenna tilt and azimuth fine tuning for optimal coverage

overlap and reduction of pilot pollution by Ec/No and RSCP improvements.

• Neighbor list optimization and identification of missing neighbors list to maintain call

completion success rate.

• Troubleshoot alarm issues and worked on issues related to dropped calls.

• Inter-RNC and Inter RAT handover monitoring, analysis and fixing the issues to meet the

thresholds.

• Voice & Data key analysis for Sector and Cluster KPI reporting for 3G networks.

• Co-ordinate drive teams and provide technical assistance.

• Extensive use of MapInfo, Google earth & MS Excel.

Jr RF Engineer with TTS Wireless Inc. (Oct 2010 – Nov 2010)

Client: Verizon (LTE)

• Performing shake down tests using Data Pro to conduct throughput/data testing relating

to site integration testing as well as cluster optimization testing.

• Processing the data using Wind Catcher tool and making necessary recommendations for

optimization and parameter changes.

Associate RF Engineer with QuadGen Wireless Solutions Inc. ( Feb 2010 – July 2010)

Client: AT&T & T-mobile

• My responsibilities include collecting drive test data for 3G UMTS network, IRAT handover

testing, stationary drive data collection and comparing throughput between Edge and HSDPA

phones, Report generation.

• Analyzing and verifying drive test data with Map info and TEMS.

• Processing & preparing AT&T GNG Cluster KPI reports for UMTS multicarrier expansion,

growth sites and cluster sites.

• Perform IRAT neighbor Analysis, parameter configurations and pilot pollution Analysis.

• Monitor & Analyze the Layer3 UMTS protocol in Agilent.

• Coordinate and assist the drive team in kit setup ( TEMS & Agilent) and ensure proper data

collection.

ACADEMIC PROJECTS:

• Digital Communication System: Worked on the physical layer simulation reference system for

a digital communication system (fixed WLAN). Designed a channel equalizer using MLSE

(Viterbi algorithm) for a multi-path channel (introducing inter-symbol interferences) with BPSK

modulation based on the assumption that the channel can be perfectly estimated at the receiver.

• Wireless Communications: System level design for Mobile wireless user terminal using

MATLAB. Performance of the system was observed by implementing Diversity scheme (MRC),

Viterbi Encoder-decoder, Puncturing and Interleaving.

• Advanced Wireless Communications: Implemented Space time coding (like space time block

coding or space time trellis code) in MIMO communication system for different combination of

transmitter and receiver such as 2 X 1, 2 X 2, 4 X 1 and 4 X 4.
