What is 5G protocol testing?

A 5G Protocol Testing job involves verifying and validating the functionality, performance, and compliance of 5G network protocols. It includes testing layers such as RRC, NAS, and PHY/MAC to ensure interoperability between network elements and devices. Engineers use test tools like Wireshark, UE simulators, and protocol analyzers to troubleshoot and optimize network performance. This role requires knowledge of 3GPP specifications, scripting, and automation to execute test cases and analyze log files.
