Two types of messages, identified below, appear in the InterReach Spectrum user

documentation:

CAUTION! Caution text indicates operations or steps that could cause personal injury, induce a safety

problem in a managed device, destroy or corrupt information, or interrupt or stop services.

NOTE: Note text contains information about special circumstances.

Standards Certification

FCC: This equipment complies with the applicable sections of Title 47 CFR, Part 22

(800 MHz Cellular), Part 24 (1900 MHz - PCS), Part 90 (800/900 - SMR), and Part

27 (700 MHz, 2100 MHz - AWS).

IC: This equipment complies with the applicable sections of RSS-131 (800/900 –

SMR), RSS-132 (800 - Cellular), and RSS-133 (1900 – PCS). The term “IC:” before

the radio certification number only signifies that Industry Canada Technical

Specifications were met.

The Manufacturer's rated output power of this equipment is for single carrier

operation. For situations when multiple carrier signals are present, the rating

would have to be reduced by 3.5 dB, especially where the output signal is

re-radiated and can cause interference to adjacent band users. This power

reduction is to be by means of input power or gain reduction and not by an

attenuator at the output of the device.

NOTE: The U.S. Federal Communications Commission (FCC) has developed guidelines for evaluation of

human exposure to RF emissions. The guidelines incorporate limits for Maximum Permissible

Exposure (MPE) for power density of transmitter operating at frequencies between 300 kHz and 100

GHz. Limits have been set for portable, mobile, and fixed equipment. ADC products fall in the

category of fixed equipment; products intended to be permanently secured and exposures are

evaluated for distances greater than 20cm (7-7/8”). Portable devices fall into exposures of less

than 20cm, where SAR evaluations are used.

Antenna gain is restricted to 1.5 W ERP (2.49 W EIRP) in order to satisfy RF exposure

compliance requirements. If higher than 1.5 W ERP, routine MPE evaluation is needed.

The antennas should be installed to provide at least 20cm from all persons to satisfy MPE

requirements of FCC Part 2, 2.1091.

UL/CUL: This will be installed in a restricted access location. This equipment

complies, per UL and CUL 50, Standard for Enclosures for Electrical Equipment.

Product Overview

InterReach Spectrum Remote Access Unit Installation Guide - Preliminary Update for Issue 3 Page 5

PRODUCT OVERVIEW

InterReach Spectrum supports up to eight frequency bands in a single system.

Each antenna location supports those bands in modular, group pairings. Each

location includes a Main Remote Access Unit (MRAU), which can power up to three

additional Secondary Remote Access Units (SRAUs). An MRAU supports two

frequency bands, and each SRAU can support up to two frequency bands, for a

total of up to eight frequency bands. MRAUs and SRAUs are grouped logically,

based on common service provider groupings and include, as an example:

•850/1900

•700/700 MIMO

•800/900 SMR

•1900/AWS.

To add more frequency bands, you connect an SRAU to the existing MRAU.

Figure 1 illustrates how RF and IF signals are sent between Spectrum units and

modules.

Install the RAUs and Antennas

InterReach Spectrum Remote Access Unit Installation Guide - Preliminary Update for Issue 3 Page 11

INSTALL THE RAUS AND ANTENNAS

Follow the steps in the order provided to install the RAUs and antennas.

Mount the RAUs and Antennas

General Safety Precautions

CAUTION! Wet conditions increase the potential for receiving an electrical shock when installing or using

electrically powered equipment. To prevent electrical shock, never install or use electrical

equipment in a wet location or during a lightning storm.

CAUTION! This system is a RF Transmitter and continuously emits RF energy. Maintain a minimum 8-inch

(20 cm) clearance from the antenna while the system is operating. Whenever possible, shut down

the RAN before servicing the antenna.

NOTE: RAUs are suitable for use in environmental air space in accordance with Section 300-22(c) of the

National Electrical Code, and Sections 2-128, 12-010(3) and 12-100 of the Canadian Electrical

Code, Part 1, CSA C22.1.

CAUTION! Install RAUs in indoor locations only. Do not connect an antenna installed in an outdoor location

to a RAU, unless it is in an approved AOC weatherproof NEMA4 housing.

CAUTION! Attach all RAUs securely to a stationary object (that is, a wall, pole, or ceiling brackets). To mount

a RAU securely to a wall, ceiling bracket, or pole, use #6 diameter fasteners in the four slotted

mounting holes.

CAUTION! Do the following to maintain proper ventilation:

• Keep at least 76 mm (3-inch) clearance around the RAU.

• Do not stack RAUs on top of each other.

• Always mount the RAU with the solid face (containing the mounting holes) against the

mounting surface.

NOTE: You can place the RAU, without its fastening hardware, on a flat surface, such as a shelf, desk,

cabinet, or any other horizontal surface that allows stable placement, with the mounting base

facing down to the mounting surface.

CAUTION! If installing the RAU on a flat surface, the surface must be able to hold a minimum 7-pound load

securely.

Install the RAUs and Antennas

Page 12 InterReach Spectrum Remote Access Unit Installation Guide - Preliminary Update for Issue 3

Do the following, in the order presented, to mount the RAUs and antennas:

1Mount all MRAU and SRAUs in the locations marked on the floor plans.

2Install the passive antennas according to the manufacturer’s installation

instructions.

NOTE: It is common practice to install passive antennas below the ceiling. If you install a passive antenna

above the ceiling, when estimating the antenna coverage area, account for additional loss due to

the ceiling material.

3Connect a passive multi-band antenna to the N connector on each RAU using

coaxial cable with the least amount of loss possible. (See “Appendix C: Omni

Antenna” on page 23 for information on the Omni Antenna ports.)

4Follow these rules for the CATV cables when connecting the IFEU to the MRAU:

•The FWD and REV cables should be close to the same length.

•The FWD and REV cables should be the same cable type (both RG6 or both

RG11).

•A pair of CATV cables connects each MRAU to the IFEU. The IFEU REV

Module IF IN port and the IFEU FWD Module IF OUT port must match. For

example, if IFEU REV Module IF IN Port 3 is used, use IFEU FWD Module IF

OUT Port 3.

•Refer to “Appendix B: 75-Ohm CATV Cable” on page 18 for information on

maximum RG-6 or RG-11 CATV cable lengths.

Appendix B: 75-Ohm CATV Cable

InterReach Spectrum Remote Access Unit Installation Guide - Preliminary Update for Issue 3 Page 19

APPENDIX B: 75-OHM CATV CABLE

The 75-Ohm CATV Cable:

•connects the IFEU to MRAU(s) and the MRAU(s) to the SRAU(s)

•transmits (FWD) multiband and receives (REV) IF signals

•delivers DC electrical power to the RAUs. The Spectrum IFEU DC voltage output

is +54Vdc nominal. If the IFEU reaches its current limit, a current-limiting

circuit protects it.

•carries configuration and status information

•uses 75 type-F connectors with captive center pins.

CATV Cable Requirements

Belden CATV cable or equivalent is required (see Figure 2).

•For the RG-6 cable, use a Belden 1695A Coax.

•For the RG-11 cable, use a Belden 7732A Coax.
