Professional Experience
RF Engineer
Further Enterprise Solutions, Cherry Hill – NJ
Project: VoLTE Optimization - T-Mobile, New Mexico January 2015 – Present
• Create cluster definition & drive routes in MapInfo based on the worst offender list as per Drop Call Rate
• Implement tilt and parameter changes at cluster level to improve CINR coverage & mitigate DCR
• Recommend parameter and threshold adjustment for events such as Handovers: A2/A3, IRAT/SRVCC: B1/B2
• Ensure VOLTE call continuity via SRVCC to UTRA/GERAN by tuning SRVCC parameters
• Generate propagation plots in ASSET to confirm no leakage occurs after tilt recommendations
• Investigate and resolve VOLTE drops such as RTP timeout, SIP release, missing handover, new invite
• Provide in-depth cause analysis for VOLTE drop calls based on Layer 3, Actix & TEMS drive test logs
• Monitor for KPIs in T-Mobile Performance and Information Manager (TPIM) after tilts & parameter changes
• Improve customer VOLTE experience by improving Accessibility, Connectivity & Mobility KPIs through optimization
Environment: ACTIX One, TEMS, MapInfo, Excel, Asset, TPIM
Project: AT&T LTE Optimization July 2014 – December 2014
• Analyze signaling flow and layer 3 messages to investigate call setup failures, and dropped calls
• Generate metrics and scanner reports of SSVs and Cluster data using AT&T GNG package in ACTIX Analyzer
• Monitor for swapped sectors, lack of dominance, handover problems, and pilot pollution
• Perform pre-launch site level and cluster optimization for NY-NJ and WABA AT&T markets
• Develop SSV and Cluster drive routes in MapInfo based on propagation plots
• Provide antenna tilt recommendations to obtain required signal coverage
• Define intra frequency, inter frequency and inter IRAT neighbors for newly launched sites
• Verify successful call origination and handoff between sectors of a node and neighboring nodes
Environment: ACTIX Analyzer, MapInfo, Excel, Macro
Project: RF Design - T-Mobile LA, NC November 2013 – June 2014
• Review Site Close-out Package for changes in antenna configurations for planned sites
• Verify System Return Loss and Distance to Fault using Anritsu Sweepmasters for T-Mobile
• Create RFDS for different antenna configurations per client request
• Calculate Link Budget Analysis for ERP and EIRP of the sites
• Create coverage plots and E911 plots using ASSET and MapInfo as part of New Site Design
• Update the necessary databases ASSET, SORT and Homer to bring monitored sites on air
Environment: Asset, Homer, MapInfo, Excel, Google Earth
