Ericsson (January 2013 – May 2013)

Worked as an Engineering Intern with Customer Network Support Team for Metro PCS. Was involved in troubleshooting end user issues caused due to Ericsson products like eNodeB’s, OSS using different Ericsson tools to monitor performance and configuration parameters. Worked with the RF team on various RF issues, Troubleshooting and optimization. Following are the list of activities performed with the RF team and Customer Network Support:

1. Daily KPI monitoring:

Prepared daily and hourly KPI (Key Performance Indicator) Reports for various markets in Metro PCS network using Ericsson tool called ENIQ and also using moshell to manually pull the values of PM counters. Used various Performance Management Counters which are responsible for influencing Accessibility, Retainability, Handover, Throughput and Latency, which are used to determine the performance of the network. Prepared KPI reports to be sent to the customer (Metro PCS).

2. UE logs & cell traces to troubleshoot RF issues:

Assembling drive testing equipment consisting of a scanner, a testing Laptop, GPS, Antenna and the testing User Equipment. Used licensed TEMS tool to collect, view and analyze drive test logs.

Testing of a Metro PCS Volte UE’s, LG spirit and Connect, which were not yet launched in the market. Collect PCAPs and TCP Dump to be investigated by the Drive Test Team.

Assisted the Drive test team to collect logs in order to analyze the location update issue for Metro PCS. Used TEMS tool to collect and view the logs.

As part of the CNS MetroPCS team, worked with the CNS Engineers on ANR issue, MIMO issue and Nationwide HO issue by pulling up various reports and by monitoring and analyzing the performance management counters and Configuration management counters.

Collected and viewed Cell traces in order to troubleshoot various issues.

3. Parameter audits:

Collected Configuration Management Dump (CM Dump) and performed Parameter Audit by using the NeXplorer tool to compare the network configuration parameters to the Baseline values.

Was assigned a project to prepare Parameter Audit for Verizon for four of its markets, which was successfully completed and submitted.

Used Moshell in order to view the PM and CM counters and also to view cell relations.

IL&FS Engineering and Construction Company Limited

Worked in (Rural Electrification) RE project for IL&FS Engineering and Construction Company Limited, India as Electrical Engineer for a period of 1 year and 2 months. Was leading a team of 25 people consisting of supervisors, workers and contractors. Tasks included Carrying sub-station survey for erection of High Tension transformer, Line Survey for Re-conducting existing high voltage lines and new 33KV and 11KV lines, augmentation of 5MVA to 10MVA transformer. Successfully completed electrification of 2 villages. Was even responsible for designing AutoCAD layouts of 33/11KV electrical substations and lines.

Also undergone training in Project Management for a period of two months in Maytas Center for Learning and Leadership Development

ACADEMIC PROJECTS:

Lab Project using OPNET tool to create an ATM network and study how the choice of the application layer and service classes affects the performance of the applications like voice, email and FTP.

Project on ‘Combined Motor Protection Unit for Motors using PIC 16F877 Microcontroller’. The microprocessor-based protection unit protects the motor from three parameters - temperature over voltage, under voltage and thermal related faults. The peripheral interrupt control microcontroller used is microchips 16F877. The PIC microcontroller is driven by the help of MPLAB software and a programmer. All the three parameters can be controlled with the help of the same protection unit.

EXTRA CURRICULAR ACTIVITIES:

Was a Volunteer for Youth Red Cross Society for 1 year.

Was a Volunteer for Rotaract Club for 1 year.

Played a key role in organizing the technical fest of Karunya University called MINDKRAFT which involved top colleges of south India.
