Contact Us6 Frequently Asked Questions about “Connection between wind-solar hybrid RRU and BBU of communication base station”
What is the difference between BBU and RRU?
Refreshing some basic concepts. BBU (Baseband Unit): manages the whole base station, including operating maintenance as will as signal processing. RRU (Remote Radio Unit): interface with Antenna in one side and with BBU in the another side. Converts the RF signal into data signal and the vice versa. Filtering and amplification of RF signal.
How does the RRU communicate with the BBU?
The communication between the RRU and the BBU is achieved through a high-capacity digital interface, such as Common Public Radio Interface (CPRI) or Open Base Station Architecture Initiative (OBSAI) protocols. These interfaces enable the transfer of baseband data and control signals between the RRU and BBU.
What are RRU and BBU in FTTA?
RRU (Radio Remote Unit) and BBU (Building Baseband Unit) are indispensable components in base station construction and FTTA. In a distributed base station architecture, the traditional macro station equipment have two distinct units based on their functions: the BBU and the RRU.
What is the difference between RRU and baseband unit?
However, with the introduction of RRUs, the RF Unit is separated into two parts: the RRU and the Baseband Unit. The RRU is responsible for handling the radio frequency functions, including signal amplification, filtering, modulation, and demodulation, whereas the Baseband Unit takes care of the baseband processing tasks.
What is a remote radio unit (RRU)?
The main functions of the Remote Radio Unit (RRU) include: Communicating with the baseband pool (BBU) through optical fiber, including I/Q data and operation and maintenance messages. Connecting to the antenna array via RF cables to perform RF signal transmission and reception.
How does the rru3929 work with the bbu3900?
The RRU provides the CPRI port for data communication with the BBU3900. When working in GSM mode, the RRU3929 adopts the direct frequency conversion technique, which is directly implemented in the transmit channel. The RRU3929 modulates the baseband signals into GSM RF signals.
