Fundamentals of LTE-A: Upper Layer Functionality and Evolved Packet Core
As the demand for mobile high-speed data connectivity continues to accelerate, carriers are ramping up deployments of the next generation of LTE*, known as LTE-A (Long Term Evolution -Advanced). Given its future role and complexity, it is vital that designers of mobile devices and wireless networking systems possess a solid understanding of the underlying fundamental concepts needed to assess the performance, conformance, and interoperability functions of LTE-A wireless systems.
Starting with a brief overview of the evolution of wireless, this course will then provide a look at the overall LTE-A architecture, followed by an examination of several physical layer features of LTE-A, and upper-layer functionality, from the media access control (MAC) through to radio link control (RLC) and spectrum/bandwidth management.
We will conclude with a study of the application of these concepts to the performance, conformance, and interoperability of LTE-A systems, including an overview of various test equipment options to provide a real-world understanding of these complex wireless networking systems at various stages of development.
