What is CPRI?

CPRI (Common Public Radio Interface) is a specification for the interface between Radio Equipment Control (REC) and Radio Equipment (RE) in wireless communication systems. It defines the data format and control mechanisms for transporting radio frequency (RF) data over a digital link, typically fiber optic cables. CPRI is commonly used in cellular base stations to connect the baseband unit (BBU) to the remote radio head (RRH), enabling centralized baseband processing and flexible radio deployment.
