Miguel Adrian Pintor

RF Optimization Engineer who led a 300-node 5G NR deployment to 99% site acceptance while managing a 30-person team across Telcel Mexico and AT&T USA — 14+ years turning underperforming networks into measurable KPI wins. End-to-end experience across 2G, 3G, LTE, VoLTE, and 5G NR (NSA) on large-scale Ericsson networks, progressing from the Ericsson Graduates Program through cluster owner, consultant, and team lead roles. Led 5+ major projects across the US and Mexico, including nationwide 5G NR deployments across Regions 1–4, 6, and 9 of Telcel.

MBA graduate combining deep RF expertise with project, budget, and team leadership.

NPM, Team Lead & Senior RF Optimization Engineer — 5G NR Initial Tuning at Ericsson — Telcel Mexico (2022-01 – Present)

• Delivered 99% site acceptance across a 300-node 5G NR (NSA) deployment (Regions 1–4, 6, 9) — full ownership of node parametrization, commissioning, neighbor design, and feature activation.
• Managed and mentored 11–20 RF engineers plus subcontractors — workforce planning, budget oversight, drive test vendor evaluation, and individual development plans.
• Cut rework and delivery delays by 10–20% through workflow redesign; served as primary technical escalation point in daily customer meetings.
• Tuned 5G/LTE parameters and activated features (Massive MIMO, Beamforming, DSS, Carrier Aggregation, SON), validating results with TEMS Investigation and Actix.
• Investigated KPI degradation using OPI/KPI counters and OSS-based root cause analysis, correlating parameter changes with performance trends.

RF Optimization Consultant, VIP Cases & Cluster Owner — Multi-Technology at Ericsson — Telcel Mexico (2015-01 – 2022-01)

• Progressed from Cluster Owner to VIP Cases Engineer to R9F Consultant over 7 years at Telcel, covering 2G, 3G, 4G, and VoLTE.
• As R9F Consultant, delivered measurable KPI gains on a mature, high-density network: 5% throughput, 3% accessibility, 0.5% retainability.
• Resolved executive escalations (30-minute SLA) via call trace and signaling analysis; performed protocol-level Layer 3 troubleshooting (RRC, SIP, Diameter, X2) with Wireshark and ANRITSU.
• Owned neighbor relations, layer management, and capacity analysis across 3G/4G clusters — implementing parameter and feature changes (MIMO, Carrier Aggregation, Beamforming, ETILT/Mtilt/azimuth, SON) to relieve congestion and balance coverage, quality, and interference.
• Improved VoLTE quality and mobility performance — reduced drop call rate (DCR) through handover optimization, and analyzed packet loss, jitter, and MOS to resolve voice quality degradation.
• Mentored Telcel engineers on Ericsson tools and presented weekly KPI performance reviews to optimization leadership.

RF Optimization Team Lead & Engineer — Pre-Launch & Post-Launch 3G/4G LTE at Ericsson — AT&T USA (2010-01 – 2015-01)

• Promoted to Team Lead after 4 months — led 15–30 engineers and served as primary customer point of contact, presenting utilization reports and driving Pre-Launch process improvements across multiple US markets.
• Conducted Iub interface congestion analysis and hardware fault troubleshooting in coordination with transmission and core network teams, resolving End-to-End performance issues beyond the RAN domain.
• Drove Post-Launch 3G/LTE worst-offender resolution in Texas — achieved sustained gains in CSSR, DCR, and HOSR — including a 4-month onsite assignment monitoring Houston, San Antonio, and Austin.
• Achieved 99% ACC/RET KPI compliance during WCDMA Post-Launch optimization — combining neighbor analysis, capacity management, and parameter audits to relieve Node B traffic congestion.
