What is RRU and BBU
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 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.
These transceivers connect wireless devices with wireless networks. RRUs have become one of the most important subsystems of today's new distributed base stations. The RRU contains the base station's RF circuitry plus analog-to-digital/digital-to-analog
1. RRU stands for Radio Remote Unit and is the distributed frequency unit that connects to an operator's network and user equipment like cell phones. It is installed below antennas on towers. 2.
