iv iRU4438 iRRH Product Description and Installation Guide
Overview
The iRU4438 intelligent Remote Radio Head is based on a distributed architecture with the
following two essential elements:
• iRU4438 iRRH
• iRB1200 iBBU or vBBU
The iRU4438 iRRH is a compact, outdoor microcell radio head with integrated baseband for
use in the AWS band. The iRU4438 iRRH is connected to the iRB1200 iBBU through a gigabit
Ethernet (GigE) connection compliant with the Common Public Radio Interface (CPRI)
standard. Connection to other compliant fronthaul devices can also be facilitated using the
Ethernet fronthaul port.
The iRU4438 iRRH interconnects with compliant radio antennas and the iRB1200 iBBU which
operates within the RAN portion of the LTE wireless network.
