Centralized RAN, or C-RAN, is poised to completely transform the way Radio Access Networks are traditionally designed. C-RAN reduces OpEx, CapEx, and energy consumption while boosting overall capacity, coverage and spectral efficiency. The session starts with an introduction to C-RAN and how it solves the challenges faced by traditional RANs. The course describes the Common Packet Radio Interface (CPRI) technology and highlights its role in C-RAN operation. The session closes with a discussion of how C-RAN facilitates implementation of LTE and LTE-Advanced features such as ICIC, CoMP, and Carrier Aggregation.

A high-level technical overview to personnel involved in product management, marketing, planning, design, engineering, and operations.

After completing this course, the student will be able to:
• Compare and contrast C-RAN with traditional RAN architectures
• Identify the expected benefits of C-RAN and describe the potential challenges associated with deploying C-RAN
• Discuss the use of CPRI within the context of C-RAN
• Describe how LTE-Advanced features can leverage C-RAN
