AMDOCS Senior RF Engineer Radio Access Network Telcel - Mexico City Dec 2015 – July 2024
• 5G NSA Features Audit & Analysis:
• Evaluated mandatory features (e.g., Massive MIMO, LTE-NR DL/UL Aggregation, LTE-NR Dual Connectivity, Basic Intelligent Connectivity, etc.) and parameters like cell range, subcarrier spacing, SSB logical configurations, bsChannelBwDl/Ul, rachPreambleFormat, endcAllowedPlmnList, endcDataUsageReportEnabled, nRPCI, nRTAC, dl256QamEnabled, etc., ensuring optimal 5G NSA deployment.
• Issue Resolutions:
• Fixed six regions VoLTE accessibility issues after the 5G launch due to parameter mismatches.
• Addressed inter-SGNB PSCell change issues and low 5G accessibility caused by misconfigurations and manual definition.
• Solved traffic disruptions from undefined MOs and optimized 5G settings to resolve accessibility issues (e.g., SFP design, nRPCI clashes, undefined GUtranCellRelation).
• Device-Specific Optimization:
• Improved six regions 5G accessibility by temporary blacklisting problematic OPPO devices and adjusting settings isEndcAllowed to a specific relation.
• Improved six regions 4G accessibility by temporary blacklisting problematic Category M devices by setting catm1SupportEnabled to FALSE from TRUE.
• Network Optimization:
• Developed fault management soft alarms to automate detection and resolution of RF path issues, coverage holes, PCI conflicts, and MIMO misconfigurations, high RSSI, improper VSWR, etc.
• Provided with a checklist contains parameters, configurations, features, power license and grantedCapacityLevel for migrating to 10 MHz from 5 MHz
• Audited six regions from SRVCC issues due to PSC clashes by changing to a new PSC and issue from congestion to a specific band by changing voicePrio value.
• Provided strategies for CA uplink issues with unsupported band combination and addressed global CA impacts from incorrect settings of the pdcchCfiMode.
• Identified low VoLTE accessibility through RCA using Pearson correlation coefficient analysis to examine relationships with other VoLTE metrics. The root cause was found to be dimensioning issues.
• Delivered RCA for robotic audio and silent call due to unsupported hardware and features.
• Implemented global MIMO strategy to change numberOfAntennasTx/Rx for the sites with high load situation for throughput improvement.
• Operational Excellence:
• Managed daily operations and VIP customer complaints, ensuring high service quality and customer satisfaction.

• Network Deployment:
• Created comprehensive documentation for deploying a 42 Mbps network for GCI Alaska, including baseline parameters, configurations, counters, and KPIs.
• Developed technical guidelines aim to provide a comprehensive approach to achieving efficient and reliable network installation and performance optimization for the MPT Myanmar project.
• Testing and Benchmarking:
• Organized and trained third party drive test engineer to collect data with the required test methodology.
• Trained Ericsson Myanmar local staff to analyze drive test logs and generate KPIs report.
• Project Contribution:
• Supported U.S. customers (e.g., AT&T, Alltel, MPCS, GCI Alaska, and T-Mobile) in resolving RSSI, VSWR, and VoLTE issues.
• Delivered radio capacity solutions for Mobilicity Canada and contributed to special event KPI monitoring and network improvements.
• Issue Resolution:
• Conducted comprehensive fault diagnosis and applied corrective measures to improve customer experience and network performance.
• Knowledge Sharing:
• Mentored junior engineers and facilitated software upgrades, ensuring continuous team development and seamless project execution.
