Baseband Unit Fundamental for Communication Signal Processing

The base band unit (BBU) is the main processing element of a wireless communication base station. It acts as the control unit of the base station performing baseband operations such as signal processing, protocol stack functions, and data flow control. The BBU utilizes mobile communication devices with radio frequency (RF) units, eg. RRUs, to provide wireless communication facilities. It is responsible for accepting the digital signals from the core network and transforms them for wireless transmission. Also, it translates signals from the mobile devices and sends the information to the core network which is fundamental for providing continuous communication services.
