4 FAQs about RRU base station communication uplink and downlink channel composition

What is a remote radio unit (RRU)?

To address this, RUs were placed on the mast, close to antennas, and in such architectures became known as Remote Radio Units (RRU) or Remote Radio Heads (RRH). Optical signals are sent to the RRU from the BBU via a fibre optic cable, referred to as Fronthaul. In 5G, the BBU is split into the Distributed Unit (DU) and the Centralised Unit (CU).

What are RRU & BBU?

RRU and BBU are crucial components in base station construction, enabling a distributed architecture that improves efficiency and reliability. RRU (Radio Remote Unit) and BBU (Building Baseband Unit) are indispensable components in base station construction and FTTA.

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.

How does RRU connect to BBU?

Via optical fiber The RRU connects to the BBU, forming a new “distributed At the base of the tower locates BBU while the RRU is at the top of the tower. The RRU is further connected to the antennas via coaxial cables and power dividers (couplers), with the main trunk using optical fiber and the branch lines using coaxial cables.
