Description

5G is Here!As network operators and vendors are working round-the-clock to develop and build 5G networks it is necessary for (us) Network Engineers to understand the 5G network architecture(s), concepts and practical deployment considerations. I have curated this course by carefully analyzing and researching each topic and the current industry-trends to give you all the necessary resources/tools/pointers to successfully build and operate 5G networks. 5G is quite different from 4G and it is necessary to understand the underlying 5G cloud-native technologies to fully embrace and understand 5G. This course is for all levels of expertise. It starts from the basics by introducing the motivation for 5G, enabling technologies including cloud-native principles and then builds on top of these concepts as we explore the 5G Core concepts in depth. 4G is going to around for quite a while and both 4G and 5G networks will need to co-exist for many years. This course covers practical deployment considerations for such 4G/5G co-existence scenarios as well.This is by-far the most comprehensive course on 5G Core networks on Udemy since all concepts are covered in-depth.  I have included easy to follow diagrams in the slides, along with references to 3GPP documents where appropriate.
