1.2 Overview
The iRU4438 intelligent Remote Radio Head is based on a distributed architecture with
the following two essential elements:
• iRU4438 iRRH
• iRB1200 iBBU
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.
A block diagram of the iRU4438 iRRH is shown in Figure 1-1.
