Network Engineer

✅ 1. End-to-End RAN Testing & Optimization

• 4G LTE / 5G NR Testing & Validation

• Network Performance Optimization (KPI, Throughput, Mobility)

• Drive Test / Log Analysis (TEMS, QXDM, Wireshark)

• Call Flow Analysis (Attach, HO, VoLTE, ENDC)

👉 This ensures the candidate can handle real network performance + field issues

✅ 2. Strong Log Analysis & Protocol Knowledge

• UE Log Analysis (QXDM, QCAT, Shannon DM)

• Protocol Stack Knowledge (L1, L2, L3 – RRC, MAC, PDCP)

• 3GPP Specs Understanding & Debugging

• Issue Troubleshooting (Call Drop, HO Failure, RLF)

👉 This is critical for deep technical troubleshooting roles

✅ 3. 5G Use Cases + Multi-Vendor Exposure

• 5G NSA/SA, ENDC, CA, MIMO (Massive MIMO)

• Multi-vendor Experience (Ericsson, Huawei, Nokia, ORAN)

• Feature Testing (MU-MIMO, UL/DL Throughput, SRS, PUCCH)

• Lab + Field Testing (Callbox, iPerf, Automation)
