A baseband unit (BBU) is a device that interprets Baseband frequencies in telecom systems including computer networks, the internet, phone networks and radio broadcasting systems. A baseband frequency is a transmission at its original frequency, before it has been altered or modulated, and it usually has a frequency range close to zero.

2023年3月2日 · The BBU is responsible for converting the analog radio signal into a digital format, which can then be processed by the digital signal processor (DSP) to extract the information carried by the signal. The BBU then processes the information and sends it to the wired network infrastructure for further processing, storage, and distribution.

2024年7月3日 · The Baseband Unit (BBU) block diagram in telecommunication networks, particularly in the context of 5G, involves several key components and configurations. They enable efficient signal processing, communication, and control functions.

2024年12月11日 · BBU in telecom stands for Baseband Unit. It is a crucial component in a mobile network infrastructure, particularly in the context of LTE (Long-Term Evolution) and 5G networks. The BBU is responsible for processing and managing the baseband signals that carry user data in a cellular network.

2019年6月7日 · Functions of BBU: 1) Provides common public radio interface (CPRI) ports or optical links for communication with RRUs and processes uplink and downlink baseband signals. 2) Provides S1 ports for communication between an E-UTRAN NodeB (eNodeB) and an MME/S-GW, and X2 ports for communication between eNodeBs.
