  1. This Course is more focused towards L2 Testing.
    1. No. Of Hours can be increased or decreased as per content. 3- All Topics are designed as per industry requirements


1. What is this course about?

Answer: – This Course will be more concentrated towards Layer 2(MAC+RLC+Physical) testing of 5G Network side (gNB Protocol stack).This course start with 4G overview and slowly enter into 5G technologies with test case writing and validating them.

2. Who can join course?

Answer:-Anyone we want to increase knowledge on 5G for personal and professional aspect.

Anyone from telecom background (RF Engineers, OSS & BSS Engineers, Optimization Engineers, O&M Engineers & Technical support Engineers) wants to switch career into Protocols Testing

3. What are benefits?

Answer: – After completion of this course you will gain 5G protocol level knowledge .Growth in career and can switch domain.

4. What practical involved?

Answer: – In practical we will learn about complete testing framework which is followed in industries and R&D centres like writing test cases, executing test cases, analysing Logs and raising issues +re-execution after issues resolved.
