Telecom Baseband Unit (BBU)
The telecom baseband unit (BBU) is the baseband processing unit of telecom systems. The BBU has the advantage of modular design, small size, high integration, low power consumption and easy deployment. A typical wireless telecom station consists of the baseband processing unit (BBU) and the RF processing unit (remote radio unit - RRU). The BBU is placed in the equipment room and connected with RRU via optical fiber. The BBU is responsible for communication through the physical interface.
