In a typical distributed base station setup, the BBU is separated from the or Remote Radio Head (RRH) :
An (Baseband Unit) is a specialized telecommunications component used to process digital signals at cellular base stations. In modern network architectures like 4G LTE and 5G , the BBU acts as the "brain" of the cell site, handling data processing, resource management, and coordination between the user's device and the core network.

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:
These two units are connected via a high-speed fiber optic cable using the Common Public Radio Interface (CPRI) or eCPRI standard. Technical Specifications
