WORK HISTORY
Technical Architect - Engineering Support @Mavenir
Gurugram, IN
5G Test Architect with strong expertise in Open RAN / vRAN feature and performance validation across O-RU, O-DU, and O-CU (O-RAN 7.2 split) supporting 5G NR (SA/NSA), VoNR, LTE, VoLTE, FWA, Cat-M and NB-IoT. Proven experience in feature testing, end-to-end system validation, and multi-vendor interoperability testing for disaggregated RAN deployments. Skilled in L1/L2/L3 protocol analysis (PHY, MAC, RLC, RRC, NGAP, XnAP, S1AP) and VoNR validation across UE–gNB–5GC–IMS. Expert in 5G performance engineering, user-plane troubleshooting, and network optimization using tools such as QXDM, XCAL, Wireshark and iPerf. Delivered production-ready 5G performance for Tier-1 operators across North America, Europe, Middle East and India while ensuring strict operator KPIs for latency, throughput, mobility, and call quality.

SKILLS
ABOUT CHOB SINGH
I specialize in making 5G/LTE and Open RAN networks perform in the real world — where latency, throughput, call stability, and interoperability actually matter.• With 15+ years in telecom R&D, system integration, and network validation, I have led performance engineering for 500+ live 5G sites across the US, Canada, UK, India, the Middle East, and Latin America, helping Tier-1 operators take networks from lab readiness to commercial-grade reliability and scale.• At Mavenir, I work on cloud-native Open RAN and 5G architectures, focusing on O-RAN 7.2x, CU/DU/RU performance, Open Fronthaul optimization, and multi-vendor interoperability. My work ensures that disaggregated RAN ecosystems deliver carrier-grade KPIs for latency, throughput, mobility, VoNR quality, and session stability.• I bring deep hands-on expertise in 5G SA & NSA, VoNR, mMIMO, mmWave, LTE-Advanced, and full-stack protocol analysis (L1/L2/L3) — including PHY, MAC/RLC, RRC, NGAP, XnAP, and S1AP — to identify and eliminate the bottlenecks that limit real-world network performance.• I design and validate cloud-native RAN platforms using Kubernetes, Docker, OpenStack, CI/CD, and Linux-based automation, enabling high-throughput, low-latency, and highly available 5G deployments at scale.• Over my career at Mavenir, Ericsson, Samsung, and Huawei, I have led performance tuning, optimization, and production rollout for operators including Airtel, Boost Mobile, Bell, STC, Quickline, and Optus, delivering stable VoNR, high-capacity FWA, and reliable mobility across multi-vendor networks.• My focus: turning complex 5G and Open RAN systems into fast, stable, and scalable networks operators can depend on.Core strengths: 5G SA/NSA, O-RAN, vRAN, CU-DU-RU integration VoNR, DSS, ENDC, mMIMO, Mobility (Xn, X2, NG) KPI, performance & interoperability validation Cloud-native RAN (Kubernetes, Docker, Linux, OpenStack) L1/L2/L3 protocol analysis & root-cause debuggingTools & Platforms: Wireshark, QXDM, QCAT, XCAL, Iperf, XCAP, Actix, TEMS, Ericsson OSS/ENM, Huawei Samsung ActixOne, Linux, Docker, Kubernetes, OpenStack, Jira.
