•RECENT EXPERIENCE: R.F Engineer - I

• TITLE:
  
• R.F Engineer -I (Sep 2007 - Present)
  
• R.F Engineering Intern (Aug 2006 - Apr 2007)
  
• COMPANY: Ericsson Inc
• COMPANY WEBSITE: www.ericsson.com
• DURATION: See above
  
• PROJECT: Ericsson was working on a project for their client "Cingular". Ericsson's RF team was responsible to tune the 3G network in various markets across US and optimize them in order to minimize parameters such as dropped calls and call set-up failures. The Plano,TX location was established as the central tuning center(CTC) for this project .
• DESCRIPTION: The drive testing team would collect data using equipment such as GPS recievers, MS (Mobile station) -Cell Phone and a scanner. This data would be logged into a computer, which would generate files called LOG files. These log files contained entire information about each and every call made by the drive testing team. The drive testing team would transfer this data over secured internet connection to the CTC from various markets around US, where the RF Engineers would analyze this data and determine reasons for any drop call, access failure, set-up failure etc and recommend any changes to the network such as antenna tilt or addition of a site etc in order to overcome any problem.
• JOB FUNCTIONS: Ericsson is using an internal tool called OMEGA for processing this data. This tool would generate some reports which would give the number of drops, set-up failures etc. In the preliminary stages, the RF intern was responsible to generate these reports using the OMEGA tool and submit them to the senior RF Engineers for analysis. Eventually the RF Interns were encouraged to start analysis of data using the TEMS tool (Ericsson). A detailed report would then be submitted to the manager explaining each and every problem. The RF intern was also responsible in assisting the OMEGA programmer in making the tool more efficient and reliable. An extensive self study was involved in order to understand the technology and the processes involved. Some other duties were designing drive routes, site verification, documentation of new changes in OMEGA tool (into the user manual) and data management.The following responsibilities were assumed as an RF Engineer -I,
  
• Responsible for design of drive test routes intended to be used by drive test teams for collection of data in a UMTS network.
• Responsible for analysis of drive test data (TEMS) for SSV (Single site verification) drives and the outputs from the analysis tool (OMEGA/Actix) to make useful inferences from it, based on Layer 3 messaging, to narrow down the problem areas. (UMTS/WCDMA)
• Validating the dropped calls, access failures, missing neighbor using TEMS to help in better analysis of KPI’s for Single Site Verification drives.
• TOOLS USED: Actix, Mapinfo, Omega, TEMS Investigation, Street & Trips, Street Atlas, Topo USA.
