Description

Whether you are a beginner in 4G Layer 2, or an experienced Technical/Managerial person, this course will help you get a head start with the 4G Radio Link Control Protocol, which is a Layer 2 RAN protocol.

For Beginners, it will provide a strong foundation in understanding the RLC features and functions as defined in the 3GPP RLC specifications.

For Experienced people, this would provide a good structured recourse, with tidbits that are not explicitly mentioned in the specification.

The FAQ list that would be available to students on completion of the course, could help in Job Interviews.

Why you want to take this course:

The instructor possesses extensive experience as an early adopter of 4G and 5G RAN protocols, having implemented them since the initial standardised specifications were introduced for 5G. Through this course, you’ll benefit from their wealth of knowledge as they provide a comprehensive explanation of RLC (Radio Link Control), a crucial aspect of 4G technology. Understanding RLC is essential for grasping the intricacies of 5G specifications, and the instructor’s expertise will greatly facilitate this process.

One notable aspect of the course structure is the careful consideration given to the duration of each sub-topic. The timing has been meticulously planned to ensure that students can maintain focus and absorb the material effectively. By breaking down complex concepts into manageable segments, the instructor creates an environment conducive to learning and comprehension.

Upon completing this hour-long session, you’ll emerge with a thorough understanding of the 4G RLC protocol. Moreover, you’ll likely find yourself inspired and motivated to further explore the vast landscape of 4G RAN technology, armed with newfound knowledge and confidence.
