Industry Certified 5G Wireless RAN Protocol Tester

5G Wireless Ran Protocol Testing

Description

This program trains participants in 5G NR RAN protocol testing and validation across L1, L2, and L3 for both gNB and UE. It covers protocol conformance, functional validation, log analysis, KPI measurement, and troubleshooting, aligning 3GPP standards with hands-on lab testing. A 4G RAN protocol refresh is included to strengthen fundamentals. The course prepares engineers for careers in 5G protocol testing, RAN QA, and interoperability validation.

Overview

This program focuses on the testing and validation of 5G NR Radio Access Network (RAN) protocols across L1, L2, and L3 for both gNB (base station) and UE (device). Participants gain hands-on expertise in:

• Protocol conformance testing
• Functional validation
• Log analysis & KPI measurement
• Troubleshooting & defect tracking

The course bridges 3GPP standards with practical lab testing, preparing engineers for roles in 5G protocol testing, RAN QA, and interoperability validation.
