5G Open RAN Evolution Path

Open RAN is an ongoing shift in mobile networks that enables telecom operators to use non-proprietary RAN components from various vendors. Specific proprietary components like the remote radio head (RRH) and baseband units (BBUs) are now disaggregated into centralized units (CU), distributed units (DU), and radio units (RU). With Open RAN, the new disaggregated functions can also be virtualized or containerized. O-RAN takes this openness further by ensuring the interfaces between the components are open and interoperable.
