What you’ll learn
This course covers 3gpp MAC protocol specification 36.321 layer details, including AMC PDUs MACE control Elements, BSR, SR, HARQ, DL-SCH, UL-SCH, Channel Mapping, Radio Link Failure, and other most important details of the protocol stack along with interaction with the PHY layer.
Requirements
Basic knowledge of wireless systems and protocols in the air interface domain.
Description
Whether you are beginner in MAC or an experienced Technical/Managerial person, this course will help you get a head start with the 4G MAC Protocol, which is a Layer 2 RAN protocol.For Beginners, it will provide a strong foundation in understanding the MAC features and functions as defined in the MAC 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 take this course
The instructor possesses extensive experience as an early adopter of 4G RAN protocols, having implemented them since the initial standardised specifications were introduced for 4G. Through this course, you’ll benefit from their wealth of knowledge as they provide a comprehensive explanation of MAC(Medium Access Control), a crucial aspect of 4G technology. Understanding MACis essential for grasping the intricacies of 4G 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 MAC 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.
