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. 1.1 Exterior 1.2 Ports
