C-RAN (cloud radio access network) is a centralized, cloud computing-based architecture for radio access networks (RAN) that enables large-scale deployment, collaborative radio technology support, and real-time virtualization capabilities.
A RAN establishes a connection between base stations and end users. In the C-RAN architecture, baseband units (BBU) are relocated from individual base stations to a centralized control and processing station, often referred to as a BBU hotel. The BBU hotel connects to the network using high-speed optical fiber and maximizes the distance between cells.
The C-RAN is a variety of cloud computing environment built on open hardware and interface cards that dynamically handle fiber links and interconnections within the station. This architecture was developed to address 5G challenges.
One of the biggest challenges is the significant increase in base station density required by the evolution from 4G to 5G, which raises site acquisition difficulty and network construction costs. In addition, the dense deployment of base stations causes severe co-channel interference, and user experience significantly deteriorates at cell edges.
C-RAN’s centralized BBU deployment simplifies site acquisition and reduces the number of required devices and power supplies at sites, lowering costs for rentals, energy and equipment rooms. Centralized BBU collaboration significantly improves performance at cell edges. These features make C-RAN the important wireless network construction mode for carriers in the future.
The C-RAN architecture also lets operators co-execute RAN functionalities along with other network functions in a data center environment, granting them the ability to more quickly offer new services over the mobile broadband network.
Other benefits include the ability to pool resources, reuse infrastructure, simplify network operations and management, support multiple technologies, reduce energy consumption, and lower capex and opex. The network also becomes more heterogeneous and self-organizing.
Carriers hope that once implemented, the C-RAN will bring even more benefits, such as easier and faster network deployments and increased network flexibility.

C-RAN is a novel mobile network architecture that can address a number of challenges operators face while trying to support growing end-user’s needs. The main idea behind C-RAN is to pool the Baseband Units (BBUs) from multiple base stations into a centralized BBU Pool for statistical multiplexing gain, while shifting the burden to the high-speed wireline transmission of In-phase and Quadrature (IQ) data.
C-RAN enables energy efficient network operation and possible cost savings on baseband resources. Furthermore, it improves network capacity by performing load balancing and cooperative processing of signals originating from several base stations.
C-RAN Training, Cloud-RAN Training or Centralized Radio Access Network training covers C-RAN principles, architecture, components, planning and design of cloud-RAN applied to 4G and 5G mobile networks.
