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.

Illustrations and photos in this document are intended to show a basic installation.
They show site and equipment configurations encountered during a typical
installation. They do not show all details and exceptions, but highlight the main points
of the installation.
Altiostar Networks, Inc. will often be referred to as Altiostar Networks, or simply
Altiostar.
The Altiostar Networks iRM4451nn00-2 intelligent Remote Radio Head will often be
referred to in the generic as the iRM4451nn00-2 iRRH, iRM4451nn00-2, or simply the
iRRH. When referring to a specific model, the full model name will be used. For
example, the iRM44510300-2 (Band 3, 1.8 GHz, with GPS external connector and
Series A connectorization). Refer to “iRM4451nn00-2 available models” in the
“Preface” to this document.
The Altiostar Networks iRB7200 virtual Baseband Unit (vBBU) is a server-based
companion unit to the iRM4451nn00-2 in the Altiostar Networks LTE macro eNodeB
solution.
The Operator or Owner of the facility and equipment where the iRM4451I00-2 iRRH is
to be installed is referred to as the Operator in this document.
The Installer may be the Operator, or any other entity assigned and approved by the
Operator, to perform the installation of the iRRH at specified Operator facilities.
NOTE
This is an example of a note used in this document that denotes important
information about the text or procedure that follows it.
The iRM4451nn00-2 interconnects with compliant radio antennas and the associated
baseband unit, i.e., vBBU (or the optional iRB1200/iRB2400 iBBUs) which operate
within the RAN portion of the LTE wireless network.

Introduction
iRM4451nn00-2 iRRH Product Description and Installation Guide 1-3
The Signal Processing Module (SPM) provides single carrier, single band, single sector
LTE eNodeB operation; it is the Gigabit interface to the Altiostar base station unit
(vBBU). It also provides for 20 MHz (max) instantaneous carrier bandwidth (IBW)
support for 3GPP LTE Release 11 advanced features, L1/L2 signal conditioning, signal
protection and signal processing of the fronthaul signal inputs, as well as eNodeB
timing recovery and synchronization from either the external GPS antenna or 1588V2
extraction of timing from the Layer 2 stratum. It supports test and reference signal 
I/O for radio conformance testing (RCT), and Data and Control interface to the radio
card.
An external alarms input is located on the side of the iRM4451 unit. There are four
sets of 2-wire dry contacts that can be software-configured to be normally open or
normally closed.
Test and Debug ports (both factory use only) are provided via a mini USB port and an
HDMI port located behind an access panel on the front of the unit.

Safety requirements
2-2 iRM4451nn00-2 iRRH Product Description and Installation Guide
The power system and RET cables will have hazardous energy and voltages present.
Follow all safety warnings and practices when servicing this equipment.
This equipment must be installed, serviced, and operated only by authorized,
qualified and trained personnel who have the necessary knowledge and practical
experience with electrical equipment and who understand the hazards that can arise
when working on this type of equipment. Observe all local and national electrical,
environmental and workplace codes.
DANGER
HAZARDOUS VOLTAGES!
Hazardous voltages can be present when the system is operating. Use
caution when removing or installing equipment.
