The primary role of a BBU is to manage baseband signals—the original frequencies of a transmission before they are modulated for radio broadcast. Key functions include:
is mounted at the top of the tower near the antennas.
These two units are connected via a high-speed fiber optic cable using the Common Public Radio Interface (CPRI) or eCPRI standard. Technical Specifications empro bbu
