Allocating radio resources and managing mobility (handovers) as users move between cell sectors.
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:
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. Core Functions of the BBU
Handling encryption and decryption protocols, such as AES and ZUC, to protect user data. Architecture: BBU and RRU
In a typical distributed base station setup, the BBU is separated from the or Remote Radio Head (RRH) :
is usually housed in an indoor equipment room or a cabinet at the base of a tower.
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
