(03/2010 – 02/2012) RF Engineer – Confidential, Plano, TX

RF Design - RFDS Engineer (Confidential 9/11-1/20), Schaumburg, IL

  • Conduct cell site scoping meeting and discuss with AT&T RF engineers what devices need to be replaced/added/removed to meet the UMTS/LTE expansion process, and then update the RFDS accordingly.
  • Create new RFDS or updating old ones with devices and parameters information for multi UMTS carriers (1st, 2nd, 3rd, 4th, and 5th carriers) and LTE sites in Chicago and WI regions. Including in—building DAS sites, like Navy Pier and O’Hare Airport.
  • Create/modify plumbing diagrams showing connection between all devices used at the cell site: Antennas, TMA, AISG, MCPA, RET unit, Diplexers, and RBS(ALU, Ericsson) based on customer needs.
  • Using different configurations/solutions for adding UMTS carriers such as OBIF, antenna sharing, and LLC/duplexer solutions.
  • Confirm the final RFDS with the costumer and save it in AT&T data base.

UMTS Pre-Launch Tuning and Optimization (Confidential 6/10 – 8/11)

  • Prepare drive test routes (MapInfo and Google Earth) within the coverage area based on the design plots and confirm it with the costumer.
  • Process drive test data output files (voice and data calls) collected using Agilent or TEMS software of the tested cell or cluster using Actix and TEMS Investigation.
  • Utilize Ericsson data base and RNDCIQ for optimization and parameter changing purpose.
  • Check the existence of major problems such as swapped antenna feeders, site not transmitting, bad RF coverage, Pilot Pollution, and interference.
  • Check the existence of site alarms like VSWR and RSSI alarms.
  • Analyze drive test data to evaluate the network KPIs such as CS/PS Drop Call rate, RRC connection success rate, HSDPA/HSUPA throughput, and SHO/IRAT success rate.
  • Perform layer 3 analysis and call trace to find the cause of drop calls, access failure, and handover failure.
  • Set up cell classifications and define possible neighbors based on priority within same carrier (Intra-
    • Frequency), two different carriers (Inter-frequency), or to GSM sites (IRAT).
  • Recommendation of Azimuth, Power, Tilt, Cell/Node/RNC parameters based on drive test data and terrain to meet expected KPI.
  • Prepare GNG reports including recommendations for enhancing network performance for the customer review.
  • Optimizing in-building DAS based on walk test measurements and report to the costumer.
