eRAN TDD RRU3259 Description 1 Overview

1 OverviewThe RRU3259 is a remote radio unit. One or more RRU3259s constitute the radio frequency(RF) part of a distributed E-UTRAN NodeB (eNodeB). The RRU3259 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. RRU3259s modulate anddemodulate baseband and RF signals, process data, amplify power, and detect standing waves.

RRU is short for remote radio unit, and E-UTRAN is short for evolved universal terrestrialradio access network.
