Baseband Unit (BBU)

The baseband unit (BBU) is a crucial component in mobile base stations, handling tasks like signal processing, resource allocation, and protocol management to ensure efficient communication between mobile devices and networks. It also ensures security through encryption and manages interference and network operations. Connected to remote radio units (RRUs) and active antenna systems (AAS), the BBU in an O-RAN architecture optimizes resource use and network performance by centralizing control of multiple radio units, with high-speed fiber optic links supporting the system.
