WORK HISTORY
Ran Transport Designer @Virgin Media O2
Own end-to-end RAN transport design and support evolving RAN architecture requirements (Ericsson and Nokia), delivering HLD/LLD solutions for 2G, 4G, and 5G (NSA/SA) deployments.• Act as design authority for synchronization architecture, optimising TDD-based networks using PTP as an assisting reference to improve resilience during GNSS outages.• Assess Ericsson hardware/software capabilities and design implications for shared-node, cascaded, and multi-operator deployment scenarios.• Develop and maintain reference designs, low-level configurations, and design standards for new site builds, ensuring scalability, consistency, and compliance with deployment guidelines.• Align transport designs with multi-operator requirements, site constraints, and interface dependencies across RAN and transport domains.• Validate designs in lab and test environments prior to deployment, ensuring operational acceptance, performance, and resilience across IP/Ethernet networks.• Collaborate with cross-functional teams to support integration, troubleshooting, and continuous improvement of design baselines.

SKILLS
ABOUT ALI NIKFAL
I’m a Senior Network Architect with 16+ years of experience delivering multi-vendor mobile network solutions across 2G–5G (NSA/SA), with growing focus on 5G Advanced, O-RAN, and future network evolution. My experience spans end-to-end network design, integration, and large-scale deployment across both the UK and international markets. I have led national 5G rollout programmes, advanced transport modernisation, and pre-commercial 5G trials, combining strong technical depth with practical delivery experience. I specialise in RAN and transport architecture, including synchronization (PTP, SyncE, GNSS), backhaul design, and multi-vendor integration (Ericsson, Nokia). My work bridges design and operations — translating complex technical requirements, vendor capabilities, and evolving network demands into scalable, standards-compliant solutions.Technical Focus: • End-to-end network design: 4G/5G (NSA/SA), RAN, transport, and core integration • RAN architecture: Macro, small cell, IBS, FWA, O-RAN and emerging concepts • Transport & Synchronization: IP/MPLS, optical, microwave, 1588v2, SyncE, GNSS • Performance & Validation: Feature validation, system integration, and deployment readiness • Tools & Automation: Atoll, Nemo, Wireshark, Grafana, InfluxDB, Python/BashLeadership & Delivery:• End-to-end ownership of HLD/LLD design, validation, and deployment readiness • Strong stakeholder engagement across engineering, vendors, and delivery teams • Proven ability to translate vendor roadmaps and technical features into design direction • 10+ years of technical training and mentoring across mobile network technologiesI’m particularly interested in roles that sit at the intersection of RAN architecture, vendor strategy, and network evolution — including design authority, roadmap, and advanced RAN solutions.
