What in the world is the 5G protocol stack? Communication technologies are often discussed in terms of constructs called protocol stacks, which outline the distinct mechanisms working together to accomplish communication. 5G is no different! The 5G protocol stack is a complex monster - difficult to understand even for seasoned network engineers. Taking a step back to examine the good old Open Systems Interconnection (OSI) model is an excellent way to further familiarize ourselves with protocol stacks as a concept and begin to understand the 5G protocol stack. Use this course to examine the OSI model and see how 5G fits into the picture. Then, use the OSI model to further appreciate some of the 5G protocol stack components and their purposes and operation. Upon completion of the course, you'll have a deeper understanding of the inner workings of the remarkable 5G protocol stack.
