- 4. Improvement Build up C-RAN architecture 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. It is an evolution of the current wireless communication system and uses the latest common public radio interface (CPRI) standard, coarse or dense wavelength division multiplexing (CWDM / DWDM) technology and millimeter wave (MM wave) transmission for long distance signals. The "C" in C-RAN can alternatively stand for centralized or collaborative.
