RRU5258 Product Description
1 Overview

Overview
The RRU5258 is a remote radio unit (RRU). One or more RRU5258 modules constitute the
radio frequency (RF) part of a distributed E-UTRAN NodeB (eNodeB). The RRU5258 can be
mounted onto a pole, stand, or concrete wall. It also can be installed close to antennas to
shorten the feeder length, reduce feeder loss, and improve system coverage. RRUs modulate
and demodulate baseband signals and RF signals, process data, amplify power, and detect
standing waves.
