remote radio unit (RRU)

A Remote Radio Unit (RRU), also known as a Remote Radio Head (RRH), is responsible for the transmission and reception of radio signals, connecting wireless devices to the network. The RRU performs functions such as receiving, transmitting, filtering, and amplifying RF signals. Typically mounted near the antenna at the top of a base station, the RRU is connected to the Baseband Unit (BBU) through optical fiber, facilitating the conversion of digital signals to RF signals and vice versa.

Remote Radio Unit (RRU) and Remote Radio Head (RRH) are often used interchangeably, but RRH is the preferred phrase in the context of 5G.
