What is eCPRI, and why is it important for 5G and open vRAN?
Common Public Radio Interface (CPRI) has been around for quite some time. But now, enhanced CPRI (eCPRI) is becoming an important technology to understand for 5G.
Before diving into eCPRI, it’s helpful to understand some of the basic topology of the cellular network, which currently uses CPRI.
At the outer circle of a cellular network topology, remote radio units (RRUs) are distributed every few miles in cities and suburban areas. These RRUs comprise antennas and also some compute functionality.
