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.

Technical and marketing personnel requiring an understanding of new technologies being deployed in LTE Radio Access Networks
