These radios are realized in different ways Standalone Radio , BBU (Base Band Unit) and RRH (Remote Radio Head), O-RAN CU (Central Unit) DU (Distributed Unit) and RU (Radio Unit). In deployments RU/RRH are deployed on top of the tower and BBU/CU-DU at bottom. The RU/RRH key functionality is to convert base band signals to RF and also amplify signal to higher power.
