Preface
About the document
This document covers the basic installation of the Altiostar Networks, Inc., iRM4451nn00-2
intelligent Remote Radio Head (iRRH) on towers, walls, roof or other structures inaccessible
to the general public.
Connections to external interfaces, including signaling, grounding, and power are described.
Descriptions of the iRM4451nn00-2 macro-cellular intelligent Remote Radio Head indicators
are also provided.
The iRB7200 virtual Baseband Unit (vBBU), the iRB1200 intelligent Baseband Unit and the
iRB2400 intelligent Baseband Unit are companion products. Refer to the Altiostar Networks
iRB1200 intelligent Baseband Unit Product Description and Installation Guide, document
number 240-00-0007, for related information.
Intended Users
The target audience for this document is installation and engineering personnel. It assumes
personnel have a basic understanding of wireless telecommunications terminology, and
experience in installing wireless telecommunications equipment.
Overview
The iRM4451nn00-2 intelligent Remote Radio Head is an energy-efficient outdoor macrocell
radio head with integrated baseband for use in several select frequency bands. Connection to
a vBBU, or the optional iRB1200 iBBU or iRB2400 iBBU, is through a Gigabit Ethernet (GigE)
connection. Connection to other compliant fronthaul devices can also be facilitated using the
Ethernet fronthaul port.
The iRM4451nn00-2 intelligent Remote Radio Head is based on a distributed architecture
with the following two essential elements:
• iRM4451nn00-2 iRRH
• iRB7200 vBBU, iRB1200 iBBU, or iRB2400 iBBU
The iRM4451nn00-2 iRRH is connected to the vBBU through a Gigabit Ethernet (GigE)
connection. Connection to other compliant fronthaul devices can also be facilitated using the
Ethernet fronthaul port.
The iRM4451nn00-2 iRRH interconnects with the described Altiostar baseband units which
operate within the RAN portion of the LTE wireless network.
