2.1 System Overview
InterReach Fusion Wideband is an intelligent fiber optics/CATV, multi-band (fre-
quencies) wireless networking system designed to handle both wireless voice and
data communications over licensed frequencies. It provides high-quality, ubiquitous,
seamless access to the wireless network in smaller buildings.
Fusion Wideband provides RF characteristics designed for large public and private
facilities such as campus environments, airports, shopping malls, subways, conven-
tion centers, sports venues, and so on. Fusion Wideband uses microprocessors to
enable key capabilities such as software-selectable band settings, automatic gain con-
trol, ability to incrementally adjust downlink/uplink gain, end-to-end alarming of all
components and the associated cable infrastructure, and a host of additional capabili-
ties.
The Fusion Wideband system supports major wireless standards and air interface pro-
tocols in use around the world, including:
• Frequencies: 850 MHz, 900 MHz, 1800 MHz, 1900 MHz, 2100 MHz
• Voice Protocols: AMPS, TDMA, CDMA, GSM/EGSM,WCDMA
System Overview
2-2 InterReach Fusion Wideband Installation, Operation, and Reference Manual
CONFIDENTIAL D-620616-0-20 Rev A
• Data Protocols: CDPD, EDGE, GPRS, WCDMA, CDMA2000, 1xRTT, EV-DO,
and Paging
The Fusion Wideband system supports two configurable bands:
• Band 1 in 60 MHz and can be configured for 2100 MHz
• Band 2 in 75 MHz and can be configured for 1800 MHz
Both bands support all protocols.
Refer to Table 2-4 for a specific list of supported RAUs.
Key System Features
• Multi-Band, supports two full band frequencies for spectrum growth.
•Superior RF performance, particularly in the areas of IP3 and noise figure.
•High downlink composite power and low uplink noise figure enables support of
a large number of channels and larger coverage footprint per antenna.
•Software configurable Main and Expansion Hubs allow the frequency bands to
be configured in the field.
•Either single-mode or multi-mode fiber can be used, supporting flexible cabling
alternatives (in addition to standard CATV 75 Ohm cabling). You can select the
cabling type to met the resident cabling infrastructure of the facility and unique
building topologies.
•Extended system “reach.” Using single-mode fiber, fiber runs can be a long as 6
kilometers (creating a total system “wingspan” of 12 kilometers). Alternatively,
with multi-mode fiber, fiber runs can be as long as 500 meters.
•Standard 75 Ohm CATV cable, can be run up to 130 meters for RG-59 cable
(140 meters for RG-6; 235 meters for RG-11 using CommScope 2065V, 2279V,
and 2293K cables).
•Flexible RF configuration capabilities, including:
• System gain:
– Ability to manually set gain in 1 dB steps, from 0 to 15 dB, on both down-
link and uplink.
•RAU:
– RAU uplink and downlink gain can be independently attenuated 10 dB in 1
dB steps.
– Uplink level control protects the system from input overload and can be
optimized for either a single operator or multiple operators/protocols.
– VSWR check on RAU reports if there is a disconnected antenna.
•Firmware Updates are downloaded (either locally or remotely) to the system
when any modifications are made to the product, including the addition of new
software capabilities and services.

ing of all fault and warning conditions, and user-friendly web browser user inter-
face OA&M software package.
2.2 System Hardware Description
The InterReach Fusion Wideband system consists of three modular components:
• 19" rack-mountable Main Hub (connects to up to 4 Expansion Hubs, except for
the One Port Main Hub configuration that supports 1 Expansion Hub)
• Converts RF signals to optical IF on the downlink; optical IF-to-RF on the
uplink
• Microprocessor controlled (for alarms, monitoring, and control)
• Auto-configurable bands
• Simplex interface to RF source
• Periodically polls all downstream RAUs for system status, and automatically
reports any fault or warning conditions
•19” rack mountable Expansion Hub (connects to up to 8 Remote Access Units)
• Optical signal conversion to electrical on the downlink; electrical to optical on
the uplink
• Microprocessor controlled (for alarms, monitoring, and control)
• Software configurable band (based on commands from the Main Hub)
• Supplies DC power to RAUs over CATV cable.
•Remote Access Unit (RAU)
• Converts IF signals to RF on the downlink; RF-to-IF on the uplink
• Microprocessor controlled (for alarms, monitoring, and control)
• Multi-band protocol independent, frequency specific units
The minimum configuration of a Fusion Wideband system is one Main Hub, one
Expansion Hub, and one RAU (1-1-1). The maximum configuration of a system is
one Main Hub, four Expansion Hubs, and 32 RAUs (1-4-32). Multiple systems can
be combined to provide larger configurations.
NOTE: The Fusion Wideband One Port Main Hub (PN: FSN-W1-MH-1P)
configuration is a cost reduced version of the Fusion Wideband Main Hub
and supports only one Expansion Hub (up to 8 RAUs).
The Fusion Wideband One Port Main Hub is “software locked” to 1 port 2
fiber ports. Additional ports are disabled internally. Please do not attempt to

System OA&M Capabilities Overview
2.3 System OA&M Capabilities Overview
InterReach Fusion Wideband is microprocessor controlled and contains firmware to
enable much of the operations, administration, and maintenance (OA&M) functionality.
Complete alarming, down to the field replaceable unit (that is, Fusion Wideband
Main Hub, Expansion Hub, and Remote Access Unit) and the cabling infrastructure,
is available. All events occurring in a system, defined as a Fusion Wideband Main
Hub and all of its associated Expansion Hubs and Remote Access Units, are automat-
ically reported to the Main Hub. The Main Hub monitors system status and communi-
cates that status using the following methods:
• Normally closed (NC) alarm contact closures can be tied to standard NC alarm
monitoring systems or directly to a base station for basic alarm monitoring.
• Connection Methods:
• The Main Hub’s front panel RJ-45 port connects directly to a PC (for local
Ethernet access).
• The Main Hub’s front panel RS-232 serial port connects directly to a modem
(for remote access).
• Remote access is also available with an optional 100BASE-T LAN switch con-
nections to the RJ-45 port.

Each Fusion Wideband Main Hub in the system constantly monitors itself, its Expan-
sion Hubs, and their downstream RAUs for internal fault and warning conditions. The
results of this monitoring are stored in memory and compared against new results.
When a Main or Expansion Hub detects a change in status, it reports a fault or warn-
ing alarm. Faults are also indicated locally by red status LEDs. Both faults and warn-
ings are reported to AdminBrowser software and displayed on a PC/laptop connected
to the Main Hub’s RJ-45 port. Passive antennas connected to the RAUs are not moni-
tored automatically. Perform a System Test to retrieve status information about
antennas.
Using AdminBrowser, you can install a new system or new components, change sys-
tem parameters, and query system status. Figure 2-4 illustrates how the system
reports its status to AdminBrowser.

2.3.2 Using Alarm Contacts
You can connect the DB-9 female connector on the rear panel of the Fusion Wide-
band Main Hub to a local base station or to a daisy-chained series of Fusion and/or
MetroReach Focus systems.
Each RAU passes its status to
the Hub.
If a fault is detected, the
ALARM LED is red. If no fault
is detected, the LED is green.
The Expansion Hub queries
the status of each RAU and
compares it to the previously
stored status.
If a fault is detected, LEDs on
the front panel turn red.

System Connectivity
When you connect MetroReach Focus or a BTS to the Fusion Wideband, the Fusion
Wideband Main Hub outputs the alarms (alarm source) and MetroReach Focus or the
BTS receives the alarms (alarm sense). This is described in Section 7.7.1 on page
7-54.
2.4 System Connectivity
The double star architecture of the Fusion Wideband system, illustrated in Figure 2-5,
provides excellent system scalability and reliability. The system requires only one
pair of fibers for eight antenna points. This makes any system expansion, such as add-
ing an extra antenna for additional coverage, potentially as easy as pulling an extra
CATV cable.

3.1 Fusion Wideband Main Hub Overview
The Fusion Wideband Main Hub (shown in Figure 3-1) distributes two individual
(Band 1 and 2) downlink RF signals from a base station, repeater, or MetroReach
Focus system to up to four Expansion Hubs, which in turn distribute the signals to up
to 32 Remote Access Units. The Main Hub also combines uplink signals from the
associated Expansion Hubs.
Fusion Wideband is a multi-band system. One RF source (Band 1 or RF1) goes to the
60 MHz band and the other RF source (Band 2 or RF2) goes to the 75 MHz band. The
system installs in a 19" equipment rack and is usually co-located with the RF source
in a telecommunications closet.

3.2.1 Optical Fiber Uplink/Downlink Ports
The optical fiber uplink/downlink ports transmit and receive optical signals between
the Main Hub and up to four Expansion Hubs using industry-standard SMF or MMF
cable. There are four fiber ports on the front panel of the Main Hub; one port per
Expansion Hub. Each fiber port has two female SC/APC connectors:
• Optical Fiber Uplink Connector
This connector (labeled UPLINK) is used to receive the uplink optical signals from
an Expansion Hub.
• Optical Fiber Downlink Connector
This connector (labeled DOWNLINK) is used to transmit the downlink optical sig-
nals to an Expansion Hub.
CAUTION: To avoid damaging the Main Hub’s fiber connector ports,
use only SC/APC fiber cable connectors when using either single-mode
or multi-mode fiber. Additionally, it is critical to system performance
that only SC/APC fiber connectors are used throughout the fiber network, includ-
ing fiber distribution panels.
3.2.2 Communications RS-232 Serial Connector
Remote Monitoring
Use a standard serial cable to connect a modem to the 9-pin D-sub male serial con-
nector for remote monitoring or configuring. The cable typically has a DB-9 female
and a DB-9 female connector. Refer to Appendix A.6 on page A-9 for the cable
pinout diagram.
Remote monitoring is also available by connecting the RJ-45 (ADMIN/LAN) port to
a LAN switch for remote Ethernet LAN access or direct dial-up router access.
Local Monitoring
Use a crossover Ethernet cable (PN-4069-ADB) to connect a laptop or PC to the
RJ-45 female connector for local monitoring or configuring using the AdminBrowser
resident software. The cable typically has a RJ-45 male connector on both ends. Refer
to Appendix A.5 on page A-8 for the cable pinout.
3.2.3 Main Hub LED Indicators
The unit’s front panel LEDs indicate faults and commanded or fault lockouts. The
LEDs do not indicate warnings or whether the system test has been performed. Use the
LEDs to provide basic information only, or as a backup when you are not using Admin-
Browser.

Upon power up, the Main Hub goes through a 20-second test to check the LED
lamps. During this time, the LEDs blink through the states shown in Table 3-1, letting
you visually verify that the LED lamps and the firmware are functioning properly.
Upon completion of initialization, the LEDs stay in one of the first two states shown
in Table 3-1.
The Main Hub automatically sends the program bands command to all connected
RAUs. A mismatched band causes a fault message to be displayed in AdminBrowser
and places the RAU in a disabled condition.
NOTE: Refer to Section 9.3.2 for troubleshooting using the LEDs.
NOTE: AdminBrowser should be used for troubleshooting the system.
Only use LEDs for backup or confirmation. However, if there are communi-
cation problems within the system, the LEDs may provide additional infor-
mation that is not available using AdminBrowser.

RAU
Downlink Path: The Expansion Hub receives downlink (Band1 and 2) optical signals from the Main Hub using fiber optic
cable. It converts the signals to electrical and sends them to up to eight Remote Access Units (RAUs) using CATV cables.
The Expansion Hub also receives configuration information from the Main Hub using the fiber optic cable and relays it to
the RAUs using CATV cable.
Uplink Path: The Expansion Hub receives uplink (Band1 and 2) IF signals from up to eight RAUs using CATV cables. It
converts the signals to optical and sends them to a Main Hub using fiber optic cable.
The Expansion Hub also receives RAU status information using CATV cable and sends it and its own status information to
the Main Hub using the fiber optic cable.

4.2.1 75 Ohm Type F Connectors
The eight type F connectors on the Expansion Hub are for the CATV cables used to
transmit and receive signals to and from RAUs. Use only 75 ohm type F connectors
on the CATV cable.
The CATV cable also delivers DC electrical power to the RAUs. The Expansion
Hub’s DC voltage output is 54V DC nominal. A current limiting circuit protects the
Hub if any port draws excessive power.
NOTE: For system performance, it is important to use only low loss solid cop-
per center conductor CATV cable with quality type F connectors that use captive
centerpin connectors. Refer to Appendix A for approved cables and connectors.

5.1 RAU Overview
The Remote Access Unit (RAU) is an active transceiver that connects to an Expan-
sion Hub using industry-standard CATV cable, which delivers RF signals, configura-
tion information, and electrical power to the RAU.
An RAU passes converted 1F to RF (Downlink) and converted RF to 1F (Uplink) sig-
nals between an Expansion Hub and an attached passive antenna where the signals
are transmitted to wireless devices as shown in Figure 5-1.

6.1 Overview
Designing a Fusion Wideband solution is a matter of determining coverage and
capacity needs. This requires the following steps:
1. Determine the wireless service provider’s requirements: Refer to Section 6.2,
“Downlink RSSI Design Goal,” on page 6-3.
The following information is typically provided by the service provider:
• Frequency (for example, 1900 MHz)
• Band (for example, “A-F” band in the PCS spectrum)
• Protocol (for example, CDMA, GSM, 1xRTT, GPRS, and so on)
• Number of sectors and peak capacity per sector (translates to the number of RF
carriers that the system will have to transmit)
• Downlink RSSI design goal (RSSI, received signal strength at the wireless
handset, for example, –85 dBm)
Overview
6-2 InterReach Fusion Wideband Installation, Operation, and Reference Manual
CONFIDENTIAL D-620616-0-20 Rev A
The design goal is always a stronger signal than the mobile phone needs. It
includes inherent factors which affect performance.
• RF source (base station or bidirectional amplifier or repeater), type of equip-
ment if possible.
2. Determine the downlink power per carrier from the RF source through the
DAS: Refer to Section 6.3, “Maximum Output Power per Carrier,” on page
6-4.
The maximum power per carrier is a function of modulation type, the number of
RF carriers, signal quality issues, regulatory emissions requirements, and Fusion
Wideband’s RF performance. Power per carrier decreases as the number of carri-
ers increases.
3. Develop an RF link budget: Refer to Section 6.5, “Estimating RF Coverage,”
on page 6-8.
Knowing both the power per carrier and RSSI design goal, you can develop an RF
downlink link budget which estimates the allowable path loss from an RAU’s
antenna to the wireless handset.
allowable path loss = power per carrier + antenna gain – design goal
Satisfactory performance can be expected as long as path loss is below this level.
4. Determine the in-building environment: Refer to Section 6.5, “Estimating
RF Coverage,” on page 6-8.
• Determine which areas of the building require coverage (entire building, public
areas, parking levels, and so on.)
• Obtain floor plans to determine floor space of building and the wall layout of
the proposed areas to be covered. Floor plans are also useful when you are
selecting antenna locations.
• If possible, determine the building’s construction materials (sheetrock, metal,
concrete, and so on.)
• Determine the type of environment:
– Open layout (for example, a convention center)
– Dense, close walls (for example, a hospital)
– Mixed use (for example, an office building with hard wall offices and cubi-
cles)
5. Determine the appropriate estimated path loss slope that corresponds to the
type of building and its layout, and estimate the coverage distance for each
RAU: Refer to Section 6.5, “Estimating RF Coverage,” on page 6-8.
Use the path loss slope (PLS), which gives a value to the RF propagation charac-
teristics within the building, to convert the RF link budget into an estimate of the
coverage distance per antenna. This helps establish the quantities of Fusion Wide-
band equipment you need. The actual path loss slope that corresponds to the spe-
cific RF environment inside the building can also be determined empirically by
performing an RF site-survey of the building. This involves transmitting a cali-

Downlink RSSI Design Goal
brated tone for a fixed antenna and making measurements with a mobile antenna
throughout the area surrounding the transmitter.
6. Determine the items required to connect to the base station: Refer to
Section 6.8, “Connecting a Main Hub to a Base Station,” on page 6-27.
Once you know the quantities of Fusion Wideband equipment to be used, you can
determine the accessories (combiners/dividers, surge suppressors, repeaters,
attenuators, circulators, and so on.) required to connect the system to the base sta-
tion.
The individual elements that must be considered in designing a Fusion Wideband
solution are explained in the following sections.
NOTE: Access the LGC Wireless Customer Portal at LGCWireless.com
for on-line dimensioning and design tools.
6.2 Downlink RSSI Design Goal
Wireless service providers typically provide a minimum downlink signal level and an
associated confidence factor when specifying coverage requirements. These two fig-
ures of merit are a function of wireless handset sensitivity and margins for fading and
body loss. Wireless handset sensitivity is the weakest signal that the handset can pro-
cess reliably and is a combination of the thermal noise in the channel, noise figure of
the handset receiver front end and minimum required SNR. Fade margins for multi-
path fading (fast or small-scale) and log-normal shadow fading (slow or large-scale)
are determined by the desired confidence factor, and other factors. Downlink RSSI
design goal calculations for the GSM protocol are shown below for a 95% area cover-
age confidence factor.

Downlink design goals on the order of –85 dBm are typical for protocols, such as
GSM. Wireless service providers may choose a higher level to ensure that in-building
signal dominates any macro signal that may be leaking into the building.
6.3 Maximum Output Power per Carrier
The following tables show the recommended maximum power per carrier out of the
RAU 50 Ohm Type-N connector for different frequencies, protocols, and numbers of
carriers. These maximum levels are dictated by RF signal quality and regulatory
emissions issues. In general, as the number of RF carrier increases, the maximum
power per carrier decreases. If these levels are exceeded, signal quality will be
degraded and/or regulator requirements will be violated. The maximum input power
to the Hub is determined by subtracting the system gain from the maximum output
power of the RAU. System gain is software selectable from 0 dB to 15 dB in 1 dB
steps. Additionally, both the uplink and downlink gain of each RAU can be reduced
by 10 dB in 1 dB steps.
When connecting a Hub to a base station or repeater, attenuation on the downlink is
typically required to avoid exceeding Fusion Wideband’s maximum output power
recommendations.
WARNING: Exceeding the maximum input power may cause perma-
nent damage to the Hub. Do not exceed the maximum composite input
power of 1W (+30 dBm) to the Hub at any time.
NOTE: These specifications are for downlink power at the RAU output (excluding
antenna).

Designing for Capacity Growth
Fusion Wideband systems are deployed to enhance in-building coverage and/or to
off-load capacity from a macro cell site. In many instances, subscriber usage
increases with time and the wireless provider responds by increasing the load on the
installed Fusion Wideband system. For example, the initial deployment might only
require two RF carriers, but four RF carriers may be needed in the future based on
capacity growth forecasts. There are two options for dealing with this scenario:
1. Design the initial coverage with a maximum power per carrier for four RF carri-
ers. This will likely result in additional RAUs.
2. Design the initial coverage for two RF carriers, but reserve RAU ports on the Hub
for future use. These ports can be used to fill potential coverage holes once the
power per carrier is lowered to accommodate the two additional carriers.

6.4 System Gain
The system gain of the Fusion Wideband defaults to 0 dB or can be set up to 15 dB in
1 dB increments. In addition, uplink and downlink gains of each RAU can be inde-
pendently decreased by 10 dB in one dB steps using AdminBrowser.
The recommended maximum lengths of CATV cable are as follows:
• For RG-59 cable 130 meters for CommScope PN 2065V.
• For RG-6 cable 140 meters for CommScope PN 2279V.
• For RG-11 cable 235 meters for CommScope PN 2293K.
If the maximum distance is not required, then copper-clad over steel center-conductor
cable may be use to reduce cable costs.
If the CATV cable is longer than the recommended distance per cable type, the gain
of the system will decrease, as shown in Table 6-2.

6.5 Estimating RF Coverage
The maximum output power per carrier (based on the number and type of RF carriers
being transmitted) and the minimum acceptable received power at the wireless device
(that is, the RSSI design goal) essentially establish the RF downlink budget and, con-
sequently, the maximum allowable path loss (APL) between the RAU’s antenna and
the wireless device. Since in-building systems, such as the Fusion Wideband, are gen-
erally downlink-limited, this approach is applicable in the majority of deployments.
Figure 6-1 Determining APL between the Antenna and the Wireless Device
APL = (P – Lcoax + G) – RSSI (1)
where:
• APL = the maximum allowable path loss in dB
• P = the power per carrier transmitted by the RAU in dBm
•L
coax = the coaxial cable loss between the RAU and passive antenna in dB
• G = the gain of the passive antenna in dBi
Coaxial cable is used to connect the RAU to an antenna. Table 6-3 lists coaxial cable
loss for various cable lengths.
You can calculate the distance, d, corresponding to the maximum allowable path loss
using equations introduced in the following sections.

6.5.1 Path Loss Equation
In-building path loss obeys the distance power law1 in equation (2):
PL = 20log10(4πd0f/c) + 10nlog10(d/d0) + Χs(2)
where:
• PL is the path loss at a distance, d, from the antenna
• d = the distance expressed in meters
•d
0 = free-space path loss distance in meters
• f = the operating frequency in Hertz.
• c = the speed of light in a vacuum (3.0 × 108 m/sec).
•n = the path loss exponent and depends on the building “clutter” and frequency
of operation
•Χs = a normal random variable that depends on partition material and geome-
tries inside the building and is accounted for by the log-normal fade margin
used in the downlink RSSI design goal calculation
As a reference, Table 6-4 provides estimates of signal loss for some RF barriers1.

6.5.3 Examples of Design Estimates
Example Design Estimate for an 1900 MHz CDMA Application
1. Design goals:
• PCS (1920 MHz = average of the lowest uplink and the highest downlink fre-
quency in 1900 MHz PCS band)
• CDMA provider
• 8 CDMA carriers in the system
• –85 dBm design goal (to 95% of the building) — the minimum received power
at the wireless device
• Base station with simplex RF connections
2. Power Per Carrier: The tables in Section 6.3, “Maximum Output Power per Car-
rier,” on page 6-4 provide maximum power per carrier information. The 1900
MHz CDMA table indicates that Fusion Wideband can support eight carriers with
a recommended maximum power per carrier of 6.5 dBm. The input power should
be set to the desired output power minus the system gain.
3. Building information:
• 16 floor building with 9,290 sq. meters (100,000 sq. ft.) per floor; total
148,640 sq. meters (1,600,000 sq. ft.).
• Walls are sheetrock construction, suspended ceiling tiles.
• Antennas used are omni-directional, ceiling mounted.
• Standard office environment, 80% hard wall offices and 20% cubicles.
4. Link Budget: In this example, a design goal of –85 dBm is used. Suppose 3 dBi
omni-directional antennas are used in the design. Then, the maximum RF propa-
gation loss should be no more than 94.5 dB (6.5 dBm + 3 dBi + 85 dBm) over
95% of the area being covered. It is important to note that a design goal such as
–85 dBm is usually derived taking into account multipath fading and log-normal
shadowing characteristics. Thus, this design goal will only be met “on average”
over 95% of the area being covered. At any given point, a fade may bring the sig-
nal level underneath the design goal.
Note that this method of calculating a link budget is only for the downlink path.
For information to calculate link budgets for both the downlink and uplink paths,
refer to Section 6.6 on page 6-14.
5. Path Loss Slope: For a rough estimate, Table 6-6, “Estimated Path Loss Slope for
Different In-Building Environments” on page 6-10, shows that a building with 80%
hard wall offices and 20% cubicles, at 1920 MHz, has an approximate path loss
slope (PLS) of 38.1. Given the RF link budget of 94.5 dB, the distance of coverage
from each RAU will be 30.2 meters (99 ft). This corresponds to a coverage area
of 2,868 sq. meters (30,854 sq. ft.) per RAU (refer to Section 6.5.1 for details on
path loss estimation). For this case we assumed a circular radiation pattern, though
the actual area covered depends upon the pattern of the antenna and the obstructions
in the facility.

6. Equipment Required: Since you know the building size, you can now estimate
the Fusion Wideband equipment quantities needed. Before you test any RF levels
in the building, you can estimate that four antennas per level will be needed. This
assumes no propagation between floors. If there is propagation, you may not need
antennas on every floor.
a. 4 antennas per floor × 16 floors = 64 RAUs
b. 64 RAUs ÷ 8 (maximum 8 RAUs per Expansion Hub) = 8 Expansion Hubs
c. 8 Expansion Hubs ÷ 4 (maximum 4 Expansion Hubs per Main Hub) = 2 Main
Hubs
Check that the fiber and CATV cable distances are as recommended. If the dis-
tances differ, use the tables in Section 6.4, “System Gain,” on page 6-6 to deter-
mine system gains or losses. The path loss may need to be recalculated to assure
adequate signal levels in the required coverage distance.
The above estimates assume that all cable length requirements are met. If Expansion
Hubs cannot be placed so that the RAUs are within the distance requirement, addi-
tional Expansion Hubs may need to be placed closer to the required RAUs locations.
An RF Site Survey and Building Evaluation is required to accurately establish the
Fusion Wideband equipment quantities required for the building. The site survey
measures the RF losses within the building to determine the actual PLS, used in the
final path loss formula to determine the actual requirements of the Fusion Wideband
system.

6.6 Link Budget Analysis
A link budget is a methodical way to account for the gains and losses in an RF system
so that the quality of coverage can be predicted. The end result can often be stated as
a “design goal” in which the coverage is determined by the maximum distance from
each RAU before the signal strength falls beneath that goal.
One key feature of the link budget is the maximum power per carrier explained in
Section 6.3. While the maximum power per carrier is important as far as emissions
and signal quality requirements are concerned, it is critical that the maximum signal
into the Main Hub never exceed 1W (+30 dBm). Composite power levels above this
limit will cause damage to the Main Hub.
WARNING: Exceeding the maximum input power of 1W (+30 dBm)
could cause permanent damage to the Main Hub.
NOTE: Visit the LGC Wireless customer portal at LGCWireless.com for
the on-line Link Budget Tool.
6.6.1 Elements of a Link Budget for Narrowband Standards
The link budget represents a typical calculation that might be used to determine how
much path loss can be afforded in a Fusion Wideband design. This link budget ana-
lyzes both the downlink and uplink paths. For most configurations, the downlink
requires lower path loss and is therefore the limiting factor in the system design. It is
for this reason that a predetermined “design goal” for the downlink is sufficient to
predict coverage distance.
The link budget is organized in a simple manner: the transmitted power is calculated,
the airlink losses due to fading and body loss are summed, and the receiver sensitivity
(minimum level a signal can be received for acceptable call quality) is calculated. The
maximum allowable path loss (in dB) is the difference between the transmitted
power, less the airlink losses, and the receiver sensitivity. From the path loss, the
maximum coverage distance can be estimated using the path loss formula presented
in Section 6.5.1.
Table 6-9 provides link budget considerations for narrowband systems.

Consideration Description
BTS Transmit Power The power per carrier transmitted from the base station output
Attenuation between
BTS and Fusion
Wideband
This includes all losses: cable, attenuator, splitter/combiner, and so forth.
On the downlink, attenuation must be chosen so that the maximum power per carrier going into the
Main Hub does not exceed the levels given in Section 6.3.
On the uplink, attenuation is chosen to keep the maximum uplink signal and noise level low enough
to prevent base station alarms but small enough not to cause degradation in the system sensitivity.
If the Fusion Wideband noise figure minus the attenuation is at least 10 dB higher than the BTS
noise figure, the system noise figure is approximately that of Fusion Wideband alone. Refer to Sec-
tion 6.8 for ways to independently set the uplink and downlink attenuations between the base station
and Fusion Wideband.
Antenna Gain The radiated output power includes antenna gain. For example, if you use a 3 dBi antenna at the
RAU that is transmitting 0 dBm per carrier, the effective radiated power (relative to an isotropic radi-
ator) is 3 dBm per carrier.
BTS Noise Figure This is the effective noise floor of the base station input (usually base station sensitivity is this effec-
tive noise floor plus a certain C/I ratio).
Fusion Wideband
Noise Figure This is Fusion Wideband’s uplink noise figure, which varies depending on the number of Expansion
Hubs and RAUs, and the frequency band. Fusion Wideband’s uplink noise figure is specified for a
1-1-8 configuration. Thus, the noise figure for a Fusion Wideband system (or multiple systems
whose uplink ports are power combined) is NF(1-1-8) + 10*log(# of Expansion Hubs). This repre-
sents an upper-bound because the noise figure is lower if any of the Expansion Hub’s RAU ports are
not used.
Thermal Noise This is the noise level in the signal bandwidth (BW).
Thermal noise power = –174 dBm/Hz + 10Log(BW).
Required C/I ratio For each wireless standard, a certain C/I (carrier to interference) ratio is needed to obtain acceptable
demodulation performance. For narrowband systems, (TDMA, GSM, EDGE, iDEN, AMPS) this
level varies from about 9 dB to 20 dB.
Mobile Transmit
Power The maximum power the mobile can transmit (power transmitted at highest power level setting).
Multipath Fade
Margin This margin allows for a certain level of fading due to multipath interference. Inside buildings there
is often one or more fairly strong signals and many weaker signals arriving from reflections and dif-
fraction. Signals arriving from multiple paths add constructively or destructively. This margin
accounts for the possibility of destructive multipath interference. In RF site surveys the effects of
multipath fading are typically not accounted for because such fading is averaged out over power
level samples taken over many locations.

Log-normal Fade
Margin This margin adds an allowance for RF shadowing due to objects obstructing the direct path between
the mobile equipment and the RAU. In RF site surveys, the effects of shadowing are partially
accounted for since it is characterized by relatively slow changes in power level.
Body Loss This accounts for RF attenuation caused by the user’s head and body.
Minimum Received
Signal Level This is also referred to as the “design goal”. The link budget says that you can achieve adequate cov-
erage if the signal level is, on average, above this level over 95% of the area covered, for example.

6.6.3 Elements of a Link Budget for CDMA Standards
A CDMA link budget is slightly more complicated because you must consider the
spread spectrum nature of CDMA. Unlike narrowband standards such as TDMA and
GSM, CDMA signals are spread over a relatively wide frequency band. Upon recep-
tion, the CDMA signal is de-spread. In the de-spreading process the power in the
received signal becomes concentrated into a narrow band, whereas the noise level
remains unchanged. Hence, the signal-to-noise ratio of the de-spread signal is higher
than that of the CDMA signal before de-spreading. This increase is called processing
gain. For IS-95 and J-STD-008, the processing gain is 21 dB or 19 dB depending on
the user data rate (9.6 Kbps for rate set 1 and 14.4 Kbps for rate set 2, respectively).
Because of the processing gain, a CDMA signal (comprising one Walsh code channel
within the composite CDMA signal) can be received at a lower level than that
required for narrowband signals. A reasonable level is –95 dBm, which results in
about –85 dBm composite as shown below.
An important issue to keep in mind is that the downlink CDMA signal is composed of
many orthogonal channels: pilot, paging, sync, and traffic. The composite power
level is the sum of the powers from the individual channels. Table 6-12 shows an
example.
This table assumes that there are 15 active traffic channels operating with 50% voice
activity (so that the total power adds up to 100%). Notice that the pilot and sync chan-
nels together contribute about 25% of the power. When measuring the power in a
CDMA signal you must be aware that if only the pilot and sync channels are active,
the power level will be about 6 to 7 dB lower than the maximum power level you can
expect when all voice channels are active. The implication is that if only the pilot and
sync channels are active, and the maximum power per carrier table says that you
should not exceed 10 dBm for a CDMA signal, for example, then you should set the
attenuation between the base station and the Main Hub so that the Main Hub receives
3 dBm (assuming 0 dB system gain).
An additional consideration for CDMA systems is that the uplink and downlink paths
should be gain and noise balanced. This is required for proper operation of soft-hand-
off to the outdoor network as well as preventing excess interference that is caused by
mobiles on the indoor system transmitting at power levels that are not coordinated
with the outdoor mobiles. This balance is achieved if the power level transmitted by
the mobiles under close-loop power control is similar to the power level transmitted
under open-loop power control.
Table 6-12 Distribution of Power within a CDMA Signal
Channel Walsh Code Number Relative Power Level
Pilot 0 20% –7.0 dB
Sync 32 5% –13.3 dB
Primary Paging 1 19% –7.3 dB
Traffic 8–31, 33–63 9% (per traffic channel) –10.3 dB

PTX + PRX = –73 dBm (for Cellular, IS-95)
PTX + PRX = –76 dBm (for PCS, J-STD-008)
where PTX is the mobile’s transmitted power and PRX is the power received by the
mobile.
The power level transmitted under closed-loop power control is adjusted by the base
station to achieve a certain Eb/N0 (explained in Table 6-13 on page 6-20). The differ-
ence between these power levels, ΔP, can be estimated by comparing the power radi-
ated from the RAU, Pdownink, to the minimum received signal, Puplink, at the RAU:
ΔP = Pdownink + Puplink + 73 dBm (for Cellular)
ΔP = Pdownink + Puplink + 76 dBm (for PCS)
It’s a good idea to keep –12 dB < ΔP < 12 dB.

Table 6-13 Additional Link Budget Considerations for CDMA
Consideration Description
Multipath Fade
Margin The multipath fade margin can be reduced (by at least 3 dB) by using different lengths of optical fiber (this
is called “delay diversity”). The delay over fiber is approximately 5µS/km. If the difference in fiber
lengths to Expansion Hubs with overlapping coverage areas produces at least 1 chip (0.8µS) delay of one
path relative to the other, then the multipaths’ signals can be resolved and processed independently by the
base station’s rake receiver. A CDMA signal traveling through 163 meters of MMF cable is delayed by
approximately one chip.
Power per car-
rier, downlink This depends on how many channels are active. For example, the signal is about 7 dB lower if only the
pilot, sync, and paging channels are active compared to a fully-loaded CDMA signal. Furthermore, in the
CDMA forward link, voice channels are turned off when the user is not speaking. On average this is
assumed to be about 50% of the time. So, in the spreadsheet, both the power per Walsh code channel (rep-
resenting how much signal a mobile will receive on the Walsh code that it is de-spreading) and the total
power are used.
The channel power is needed to determine the maximum path loss, and the total power is needed to deter-
mine how hard the Fusion Wideband system is being driven.
The total power for a fully-loaded CDMA signal is given by (approximately):
total power = voice channel power + 13 dB + 10log10 (50%)
= voice channel power + 10 dB
Information Rate This is simply
10log10(9.6 Kbps) = 40 dB for rate set 1
10log10(14.4 Kbps) = 42 dB for rate set 2

Other CDMA Issues
• Never combine multiple sectors (more than one CDMA signal at the same fre-
quency) into a Fusion Wideband system. The combined CDMA signals will inter-
fere with each other.
• Try to minimize overlap between in-building coverage areas that utilize different
sectors, as well as in-building coverage and outdoor coverage areas. This is impor-
tant because any area in which more than one dominant pilot signal (at the same
frequency) is measured by the mobile will result in soft-handoff. Soft-handoff
decreases the overall network capacity by allocating multiple channel resources to
a single mobile phone.
Process Gain The process of de-spreading the desired signal boosts that signal relative to the noise and interference.
This gain needs to be included in the link budget. In the following formulas, PG = process gain:
PG = 10log10(1.25 MHz / 9.6 Kbps) = 21 dB rate set 1
PG = 10log10(1.25 MHz / 14.4 Kbps) = 19 dB rate set 2
Note that the process gain can also be expressed as 10log10 (CDMA bandwidth) minus the information
rate.
Eb/No This is the energy-per-bit divided by the received noise and interference. It’s the CDMA equivalent of sig-
nal-to-noise ratio (SNR). This figure depends on the mobile’s receiver and the multipath environment. For
example, the multipath delays inside a building are usually too small for a rake receiver in the mobile (or
base station) to resolve and coherently combine multipath components. However, if artificial delay can be
introduced by, for instance, using different lengths of cable, then the required Eb/No is lower and the mul-
tipath fade margin in the link budget can be reduced in some cases.
If the receiver noise figure is NF (dB), then the receive sensitivity (dBm) is given by:
Psensitivity = NF + Eb/No + thermal noise in a 1.25 MHz band – PG
= NF + Eb/No – 113 (dBm/1.25 MHz) – PG
Noise Rise On the uplink, the noise floor is determined not only by the Fusion Wideband system, but also by the num-
ber of mobiles that are transmitting. This is because when the base station attempts to de-spread a particu-
lar mobile’s signal, all other mobile signals appear to be noise. Because the noise floor rises as more
mobiles try to communicate with a base station, the more mobiles there are, the more power they have to
transmit. Hence, the noise floor rises rapidly:
noise rise = 10log10(1 / (1 – loading))
where loading is the number of users as a percentage of the theoretical maximum number of users.
Typically, a base station is set to limit the loading to 75%. This noise ratio must be included in the link
budget as a worst-case condition for uplink sensitivity. If there are less users than 75% of the maximum,
then the uplink coverage will be better than predicted.
Hand-off Gain CDMA supports soft hand-off, a process by which the mobile communicates simultaneously with more
than one base station or more than one sector of a base station. Soft hand-off provides improved receive
sensitivity because there are two or more receivers or transmitters involved. A line for hand-off gain is
included in the CDMA link budgets worksheet although the gain is set to 0 dB because the in-building
system will probably be designed to limit soft-handoff.

6.6.5 Considerations for Re-Radiation (Over-the-Air) Systems
Fusion Wideband can be used to extend the coverage of the outdoor network by con-
necting to a roof-top donor antenna pointed toward an outdoor base station. Addi-
tional considerations for such an application of Fusion Wideband are:
• Sizing the gain and output power requirements for a bi-directional amplifier
(repeater).
• Ensuring that noise radiated on the uplink from the in-building system does not
cause the outdoor base station to become desensitized to wireless handsets in the
outdoor network.
• Filtering out signals that lie in adjacent frequency bands. For instance, if you are
providing coverage for Cellular B-band operation it may be necessary to filter out
the A, A’ and A” bands which may contain strong signals from other outdoor base
stations.
Further information on these issues can be found in LGC Wireless’ application notes
for re-radiation applications.

CONFIDENTIAL D-620616-0-20 Rev A
6.7 Optical Power Budget
Fusion Wideband uses SC/APC connectors. The connector losses associated with
mating to these connectors is accounted for in the design and should not be included
as elements of the optical power budget. The reason is that when the optical power
budget is defined, measurements are taken with these connectors in place.
The Fusion Wideband optical power budget for both multi-mode and sin-
gle-mode fiber cable is 3.0 dB (optical).
The maximum loss through the fiber can not exceed 3 dB (optical). The maximum
lengths of the fiber cable should not exceed 500m (1,640 ft) for multi-mode and 6 km
(19,685 ft) for single-mode. Both the optical budget and the maximum cable length
must be taken into consideration when designing the system.
NOTE: It is critical to system performance that only SC/APC fiber connectors are
used throughout the fiber network, including fiber distribution panels.

Connecting a Main Hub to a Base Station
6.8 Connecting a Main Hub to a Base Station
The Fusion Wideband system supports up to two RF sources: one for Band 1, and one
for Band 2. This section explains how each band can be connected to its associated
base station.
Each Fusion Main Hub band has separate system gain parameters. For example, Band
1 can be set for +5 dB of downlink system gain while Band 2 can have +15 dB of
downlink system gain. Thus, each band can be configured as a separate system to
allow for full integration to its associated base station.
When connecting each of the Fusion Main Hub bands to its base station, the follow-
ing equipment may be required: circulators, filter diplexers, directional couplers,
combiner/splitters, attenuators, coax cables, and connectors. In addition, use the fol-
lowing considerations to achieve optimal performance:
1. The downlink power from the base stations must be attenuated enough so that the
power radiated by the RAU does not exceed the maximum power per carrier listed
in Section 6.3, “Maximum Output Power per Carrier,” on page 6-4.
2. The uplink attenuation should be small enough that the sensitivity of the overall
system is limited by Fusion Wideband, not by the attenuator. However, some base
stations trigger alarms if the noise or signal levels are too high. In this case the
attenuation must be large enough to prevent this from happening.
CAUTION:The UPLINK and DOWNLINK ports cannot handle a DC power
feed from a BTS. If DC power is present, a DC block must be used or the
Fusion Wideband Main Hub may be damaged.
If, in an area covered by Fusion Wideband, a mobile phone indicates good signal
strength but consistently has difficulty completing calls, it is possible that the attenua-
tion between Fusion Wideband and the base station needs to be adjusted. In other
words, it is possible that if the uplink is over-attenuated, the downlink power will pro-
vide good coverage, but the uplink coverage distance will be small.
When there is an excessive amount of loss between the Fusion Wideband Main Hub
uplink and its associated band’s base station, the uplink system gain can be increased
to as much as 15 dB to prevent a reduction in the overall system sensitivity.
6.8.1 Uplink Attenuation
The attenuation between the Main Hub’s uplink port and the associated band’s base
station reduces both the noise level and the desired signals out of Fusion Wideband.
Setting the attenuation on the uplink is a trade-off between keeping the noise and
maximum signal levels transmitted from Fusion Wideband to the base station
receiver low while not reducing the SNR (signal-to-noise ratio) of the path from the
Connecting a Main Hub to a Base Station
6-28 InterReach Fusion Wideband Installation, Operation, and Reference Manual
CONFIDENTIAL D-620616-0-20 Rev A
RAU inputs to the base station inputs. This SNR can not be better than the SNR of
Fusion Wideband by itself, although it can be significantly worse.
A good rule of thumb is to set the uplink attenuation such that the noise level out of
Fusion Wideband is within 10 dB of the base station’s sensitivity.
6.8.2 RAU Attenuation and ALC
The RAU attenuation and ALC are set using the AdminBrowser Edit Unit Proper-
ties screen.
Embedded within the uplink RF front-end of each Fusion Wideband RAU band is an
ALC circuit. This ALC circuit protects the Fusion Wideband system from overload
and excessive intermodulation products due to high-powered mobiles or other signal
sources that are within the supported frequency band and are in close proximity to the
RAU.
Each individual Band (1or 2) of a Fusion Wideband RAU has an uplink ALC circuit
that operates as a feedback loop. A power detector measures the level of each band’s
uplink RF input and if that level exceeds –30 dBm, an RF attenuator is activated. The
level of attenuation is equal to the amount that the input exceeds –30 dBm. The fol-
lowing sequence describes the operation of the ALC circuit, as illustrated in
Figure 6-2.
1. The RF signal level into either Band of the RAU rises above the activation thresh-
old (–30 dBm), causing that ALC loop to enter into the attack phase.
2. During the attack phase, the ALC loop increases the attenuation (0 to 30 dB) until
the detector reading is reduced to the activation threshold. The duration of this
attack phase is called the attack time.
3. After the attack time, the ALC loop enters the hold phase and maintains a fixed
attenuation so long as the high-level RF signal is present.
4. The RF signal level drops below the release threshold (–45 dBm) and the ALC
loop enters the release phase.
5. During the release phase, the ALC loop holds the attenuation for a fixed period
then quickly releases the attenuation.
An important feature of the ALC loop is that in Step 3, the attenuation is maintained
at a fixed level until the signal drops by a significant amount. This prevents the ALC
loop from tracking variations in the RF signal itself and distorting the waveform
modulation.

Figure 6-2 ALC Operation
6.8.2.1 Using the RAU 10 dB Attenuation Setting
Each RAU band can, independently of the other RAUs in a system, have its uplink or
downlink gain attenuated by 10dB in 1dB steps for each RAU band (1 or 2). This is
accomplished by selecting the appropriate UPLINK and/or DOWNLINK attenuation
for each RAU band in the Edit Unit Properties screen of AdminBrowser for the
selected RAU.
•Downlink Attenuation: The downlink attenuator provides a mechanism to reduce
the signal strength from an RAU band. For instance, this could be for an RAU
band located near a window in a tall building that is causing excessive leakage to
the macro-network. In such a case it is important to attenuate the downlink only.
The uplink should not be attenuated. If the uplink is attenuated, the uplink sensitiv-
ity is reduced and mobile phones in the area of that RAU band will have to trans-
mit at a higher power. This would increase interference to the outdoor network
from such mobiles.
•Uplink Attenuation: The uplink attenuator attenuates environmental noise picked
up by an RAU band located in an area where heavy electrical machinery is operat-
ing. In such environments the electrical noise can be quite high and it is useful to
reduce the amount of such noise that gets propagated through the distributed
antenna system. Attenuating the uplink of an RAU band located in areas of high
electrical noise helps preserve the sensitivity of the rest of the system.
The effect of activating the uplink or downlink attenuators is to reduce the coverage
area of the adjusted RAU band. The coverage radius will be reduced by roughly a fac-
tor of 2. More specifically, if d is the coverage distance without attenuation and d’ is
the coverage radius with the attenuation, then
where PLS is path loss slope (dBm).

6.8.2.2 Using the Uplink ALC Setting
Uplink automatic level control (UL ALC) circuitry for each band within the RAU
provides automatic level control on high-power signals in the uplink path. This func-
tionality is required to prevent RF signal compression caused by a single or multiple
wireless devices in very close proximity to the RAU band. Compression causes signal
degradation and, ultimately, dropped calls and data errors, and should be prevented.
Two settings are available to optimize UL ALC performance:
•Multiple Operators: Use when more than one operator and/or protocol is present
in the Fusion Wideband system’s band frequency or adjacent frequency bands.
This setting is most commonly used.
•Single Operator and Protocol: Use when only one operator and protocol is
on-the-air within the Fusion Wideband system’s configured and adjacent fre-
quency bands. This setting is seldom used.

NOTE: Faulty cabling is the cause of a vast majority of problems. All CATV cable
should be tested to TIA-570-B specifications.
7.1.1 Component Location Requirements
Fusion Wideband components are intended to be installed in indoor locations only.
If outdoor installation is desired, such as a parking garage, the Fusion Wideband com-
ponents must be installed in the appropriate environmental enclosures.
7.1.2 Cable and Connector Requirements
Fusion Wideband equipment operates over the following:
• CATV 75 Ohm cable with F connectors
• Single-mode fiber (SMF) or multi-mode (MMF) cable with SC/APC fiber connec-
tors throughout the fiber network, including fiber distribution panels
These cables are widely-used, industry standards for the cable TV industry. The regu-
lations and guidelines for Fusion Wideband cable installation are identical to those
specified by the TIA/EIA 568-B standard and the TIA/EIA/570-A standards.
LGC Wireless recommends solid copper center conductor, plenum-rated CATV
cable and connectors for conformity to building codes, standards, and to ensure stated
performance of maximum distance and RF specifications.
CommScope 2065V cable or equivalent is required for RG-59.
CommScope 2279V cable or equivalent is required for RG-6.
CommScope 2293K cable may also be used for RG-11.
NOTE: Refer to Appendix A for more information related to 75 Ohm
CATV.
LGC Wireless recommends connectors with fixed centerpins to ensure proper seating
and to eliminate oxidation, which occurs with bare center conductors. Recommended
connectors are as follows:

Safety Precautions
WARNING: Observe the following warning about viewing fiber
ends in ports. Do not stare with unprotected eyes at the connector
ends of the fibers or the ports of the hubs. Invisible infrared radia-
tion is present at the front panel of the Main Hub and the Expansion
Hub. Do not remove the fiber port dust caps unless the port is going
to be used. Do not stare directly into a fiber port.
•Test fiber cables: When you test fiber optic cables, connect the optical power
source last and disconnect it first. Use Class 1 test equipment.
•Fiber ends: Cover any unconnected fiber ends with an approved cap. Do not use
tape.
•Broken fiber cables: Do not stare with unprotected eyes at any broken ends of the
fibers. Laser light emitted from fiber sources can cause eye injury. Avoid contact
with broken fibers; they are sharp and can pierce the skin. Report any broken fiber
cables and have them replaced.
•Cleaning: Be sure the connectors are clean and free of dust or oils. Use only
approved methods for cleaning optical fiber connectors.
•Modifications: Do not make any unauthorized modifications to this fiber optic
system or associated equipment.
•Live work: Live work is permitted because LGC Wireless equipment is a Class 1
hazard.
•Signs: No warning signs are required.
•Class 1 laser product: The system meets the criteria for a Class 1 laser product

Connecting the Fiber Cables to the Main Hub
Considerations:
• Before connecting the fiber cables, confirm that their optical loss does not exceed
the 3 dB optical budget.
• If you are using fiber distribution panels, confirm that the total optical loss of fiber
cable, from the Main Hub through distribution panels and patch cords to the
Expansion Hub, does not exceed the optical budget.
• Make sure the fiber cable’s connectors are SC/APC (angle-polished). Using any
other connector type will result in degraded system performance and may damage
the equipment. (You can use an SC/APC pigtail if the fiber cable’s connectors are
not SC/APC. Refer to“Fusion Splicing of Fiber and Pigtail” on page 7-40. Or, you
can change the fiber’s connector to SC/APC.)
NOTE: Observe all Fiber Port Safety Precautions listed in Section 7.2.3 on page 7-4.

To clean the fiber ports:
You can clean the Hub’s fiber ports using canned compressed air or isopropyl alcohol
and foam tipped swabs.
Considerations:
• If using compressed air:
• The air must be free of dust, water, and oil.
• Hold the can level during use.
• If using isopropyl alcohol and foam tipped swabs:
• Use only 98% pure or more alcohol
Procedure using compressed air:
1. Remove the port’s dust cap.
2. Spray the compressed air away from the unit for a few seconds to clean out the
nozzle and then blow dust particles out of each fiber port.
Procedure using isopropyl alcohol:
1. Remove the connector’s dust cap.
2. Dip a 2.5mm lint-free, foam-tipped swab in isopropyl alcohol and slowly insert
the tip into the connector.
3. Gently twist the swab to clean the port.
4. Insert a dry swab into the port to dry it.
Additionally, you can use compressed air after the alcohol has completely evapo-
rated.
To clean the fiber ends:
Be sure that the fiber cable’s SC/APC connectors are clean and free of dust and oils.
You need lint-free cloths, isopropyl alcohol, and compressed air
1. Moisten a lint-free cloth with isopropyl alcohol.
2. Gently wipe the fiber end with the moistened cloth.
3. Using a dry lint-free cloth, gently wipe the fiber end.
4. Spray the compressed air away from the connector for a few seconds to clean out
the nozzle and then use it to completely dry the connector.
To test the fiber cables:
Perform cable testing and record the results. Test results are required for the final
As-Built Document.
To connect the fiber cables:
The fiber cable is labeled with either 1 or 2, or is color-coded. In addition to these
labels, you should add a code that identifies which port on the Main Hub is being
Help Hot Line (U.S. only): 1-800-530-9960 7-17
D-620616-0-20 Rev A CONFIDENTIAL
Fusion Wideband Installation Procedures
used and which Expansion Hub the cables are intended for. This differentiates the
connectors for proper connection between the Main Hub and Expansion Hubs.
For example:
First pair to Main Hub port 1: 11 (uplink), 12 (downlink);
Second pair to Main Hub port 2: 21 (uplink), 22 (downlink);
Third pair to Main Hub port 3: 31 (uplink), 32 (downlink); and so on.
NOTE: The Fusion Wideband One Port Main Hub (PN: FSN-1-MH-1P)
configuration is a cost reduced version of the Fusion Wideband Main Hub
and supports only one Expansion Hub (up to 8 RAUs).
If the fiber jumper is labeled with 1 or 2:
1. Connect 1s to UPLINK ports on the Main Hub.
2. Connect 2s to DOWNLINK ports on the Main Hub.
3. Record which cable number and port number you connected to UPLINK and
DOWNLINK.
This information is needed when connecting the other end of the fiber cable to the
Expansion Hub’s fiber ports.
The fiber port LEDs should be off, indicating that the Expansion Hub(s) are not
connected.
If the fiber jumper is color-coded (for example, “blue” or “red”):
1. Connect “blue” to UPLINK ports on the Main Hub.
2. Connect “red” to DOWNLINK ports on the Main Hub.
3. Record which color and port number you connected to UPLINK and DOWNLINK.
This information is needed when connecting the other end of the fiber cable to the
Expansion Hub’s fiber ports.
The fiber port LEDs should be off, indicating that the Expansion Hub(s) are not
connected.

Fusion Wideband Installation Procedures
2. Turn on the power to the Expansion Hub and check that all the LED lamps are
functioning properly.
Upon power-up, the LEDs blinks for five seconds as a visual check that they are
functioning. After the five-second test:
• The POWER and UL STATUS LEDs should be green.
– If the uplink fiber is not connected, the UL STATUS LED turns red indicating
that there is no communication with the Main Hub.
• The E-HUB STATUS and DL STATUS LEDs should be red.
• All port LEDs should be off because no RAUs are connected yet.
Connecting the Fiber Cables to the Expansion Hub
Considerations:
• Before connecting the fiber cables, confirm that their optical loss does not exceed
3 dB optical budget. RL is less than -60dB.
• If fiber distribution panels are used, confirm that the total optical loss of fiber
cable, from the Main Hub through distribution panels and patch cords to the
Expansion Hub, does not exceed the optical budget.
• Make sure the fiber cable’s connectors are SC/APC (angle-polished).Using any
other connector type will result in degraded system performance and may damage
the equipment. (You can use an SC/APC pigtail if the fiber cable’s connectors are
not SC/APC, refer to “Fusion Splicing of Fiber and Pigtail” on page 7-40, or
replace the connectors.)
NOTE: Observe all Fiber Port Safety Precautions listed in Section 7.2.3 on page 7-4.
To connect the fiber cables:
The fiber cable is labeled with either 1 or 2, or is color-coded. For proper connection
between the Main Hub ports and the Expansion Hub ports, refer to the numbering or
color-coded connections you recorded when installing the Main Hub(s).
If the fiber jumper is labeled with 1 or 2:
1. Connect 2 to DOWNLINK on Expansion Hub.
The DL STATUS LED should turn green as soon as you connect the fiber. If it does
not, there is a downlink problem. Make sure you are connecting the correct cable
to the port.
2. Connect 1 to UPLINK on Expansion Hub.
The UL STATUS LED turns green on the first Main Hub communication. It may
take up to 20 seconds to establish communication.
The Expansion Hub’s E-HUB STATUS LED turns green when the Main Hub sends
it the frequency band command.
Fusion Wideband Installation Procedures
7-30 InterReach Fusion Wideband Installation, Operation, and Reference Manual
CONFIDENTIAL D-620616-0-20 Rev A
If the UL STATUS and E-HUB STATUS LEDs do not turn green/green, check the
Main Hub LEDs. Refer to page 7-24, item 2 in Table 7-5.
If the fiber jumper is color-coded (for example, “blue” or “red”):
1. Connect “red” to DOWNLINK on Expansion Hub.
The DL STATUS LED should turn green as soon as you connect the fiber. If it does
not, there is a downlink problem. Make sure you are connecting the correct cable
to the port.
2. Connect “blue” to UPLINK on Expansion Hub.
The UL STATUS LED turns green on the first Main Hub communication. It may
take up to 20 seconds to establish communication.
The Expansion Hub’s E-HUB STATUS LED turns green when the Main Hub sends
it the frequency band command.
If the UL STATUS and E-HUB STATUS LEDs do not turn green/green, check the
Main Hub LEDs. See page 7-24, item 2 in Table 7-5.
Connecting the 75 Ohm CATV Cables
Considerations:
• Verify that the cable has been tested and the test results are recorded. This informa-
tion is required for the As-Built Document.
• Verify that only captive centerpin F connectors are used on the solid copper center
conductor CATV cable from CommScope (or equivalent).
• Verify that the CATV cable is labeled with:
• Fusion Wideband Expansion Hub port number being used
• RAU identifier
• Carrier (for multiple operator systems)
To connect the CATV cables:
1. Connect the CATV cables to the F ports according to the labels on the cables.
The STATUS LEDs should be off because the RAUs are not connected at the other
end of the CATV cable.
2. Record which cable you are connecting to which port (that is, from the label on
the cable).
This information is required for the As-Built Document.
3. Tie-off the cables or use the optional cable manager to avoid damaging the con-
nectors because of cable strain.

7.4.3 Installing RAUs
CAUTION: Install RAUs in indoor locations only. Do not con-
nect an antenna that is installed in an outdoor location to an RAU.
For outdoor installations, a protective enclosure is required.
Installing RAUs
Mount all RAUs in the locations marked on the floor plans.
Considerations:
• You can place the unit, 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. For mounting to
other locations (that is, walls, ceilings, poles) the RAU must be securely mounted
using the 4 slotted mounting holes provided with #6 diameter fasteners. This
method of mounting must securely hold a minimum of 7 lbs. load.
• Attach the RAU securely to a stationary object (that is, a wall, pole, or ceiling tile).
• For proper ventilation:
• Keep at least 76 mm (3 in.) clearance around the RAU to ensure proper venting.
• 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.
Installing Passive Antennas
Refer to the manufacturer’s installation instructions to install passive antennas.
Location
Passive antennas are usually installed below the ceiling. If they are installed above
the ceiling, you must consider the additional loss due to the ceiling material when
estimating the antenna coverage area.
Connecting the Antenna to the RAU
Connect a passive multi-band antenna to the N connector on the RAU using coaxial
cable with the least amount of loss possible.
CAUTION: Firmly hand-tighten the N connector – DO NOT
over-tighten the connector.

sanctions of the national jurisdiction involved. Ownership of LGC Wireless
equipment carries no automatic right of use.
7.5 Splicing Fiber Optic Cable
The fiber cable must have SC/APC connectors for the entire run. If it does not, you
can splice a pigtail, which has SC/APC connectors, to the fiber cable.
LGC offers two pigtails: one for single-mode fiber (PN 4013SCAPC-3) and one for
multi-mode fiber (PN 4012SCAPC-3).
LGC Wireless recommends fusion splices because they have the lowest splice loss
and return loss. Mechanical splices have higher losses and higher back reflection than
fusion splices and are not recommended.
Using a fusion splicer involves fusing together two butted and cleaved ends of fiber.
The fusion splicer aligns the fibers and maintains alignment during the fusion pro-
cess. fusion splices have very low loss (typically less than 0.05 dB) and very low
back reflection (return loss). Fusion splices should be organized in a splice tray
designed to store and protect the splices.
Fusion Splicing of Fiber and Pigtail
Before you begin, make sure the fusion splicer is set to the proper mode (that is,
single- or multi-mode).
To fusion splice the fiber optic cable to the SC/APC pigtail: Option A
1. Secure both the fiber cable and the SC/APC pigtail in a splice tray that is installed
immediately adjacent to the Hub.
2. Prepare the fiber end by cutting back the polyethylene jacket, the kevlar or fiber-
glass strength members, the extruded coating, and the buffer coating in order to
expose the “bare fiber” – cladding plus core.
Ensure that sufficient slack is maintained in order to be able to reach the fusion
splicer.
3. Clean the unclad fiber core using isopropyl alcohol and lint-free wipes.
4. Cleave the unclad fiber to the length prescribed by the fusion splicer’s specifica-
tion sheets.
5. Repeat steps 2 through 4 for the SC/APC pigtail.
6. Pass the splice sleeve onto the fiber strand.
7. Position both fiber ends in the fusion splicer and complete splice in accordance
with the fusion splicer’s operation instructions.

8. Ensure that the estimated loss for the splice as measured by the fusion splicer is
0.10 dB or better.
9. Slide the fusion splicing sleeve over the point of the fusion splice.
10. Place the sleeve and fused fiber into the fusion splicer’s heater.
11. Allow time for the splice sleeve to cure.
12. Return fiber splice to the splice tray, store the sleeve in a splice holder within the
tray, and store excess cable length in accordance with the tray manufacture’s
directions.
After successfully testing the fiber, plug the SC/APC pigtail into the proper opti-
cal port on the Hub.
To fusion splice the fiber optic cable to the SC/APC pigtail: Option B
1. Secure both the fiber cable and the SC/APC pigtail in a splice tray portion of a
fiber distribution panel.
2. Prepare the fiber end by cutting back the polyethylene jacket, the kevlar or fiber-
glass strength members, the extruded coating, and the buffer coating in order to
expose the “bare fiber” – cladding plus core.
Ensure that sufficient slack is maintained in order to be able to reach the fusion
splicer.
3. Clean the unclad fiber core using isopropyl alcohol and lint-free wipes.
4. Cleave the unclad fiber to the length prescribed by the fusion splicer’s specifica-
tion sheets.
5. Repeat steps 2 through 4 for the SC/APC pigtail.
6. Pass the splice sleeve onto the fiber strand.
7. Position both fiber ends in the fusion splicer and complete splice in accordance
with the fusion splicer’s operation instructions.
8. Ensure that the estimated loss for the splice as measured by the fusion splicer is
0.10 dB or better.
9. Slide the fusion splicing sleeve over the point of the fusion splice.
10. Place the sleeve and fused fiber into the fusion splicer’s heater.
11. Allow time for the splice sleeve to cure.
12. Return fiber splice to the splice tray, store the sleeve in a splice holder within the
tray, and store excess cable length in accordance with the tray manufacture’s
directions.
13. After successfully testing the fiber cable, plug the SC/APC pigtail into the back
side of the SC/APC bulkhead in the Fiber Distribution Panel.
Install a SC/APC patch cord between the front side of the SC/APC bulkhead and
the proper optical port on the Hub.

7.7 Connecting Contact Alarms to a Fusion Wideband
System
The Fusion Wideband Main Hub can generate (source) two contact alarms as well as
sense three external contact alarm.
• Alarm Source (refer to Section 7.7.1 on page 7-54)
The Fusion Wideband Main Hub has two alarm contacts, fault (major) and warn-
ing (minor). These contacts are normally-closed (NC) and will open when an inter-
nal alarm is detected.
NOTE: The contact can be changed to normally-open (NO) with Admin-
Browser. This is not recommended since no alarm would be sent if power to
the Fusion Wideband Main Hub fails.
• Fault is activated when any faults or disconnects are detected.
• Warning is activated when any warning conditions are detected except lockout
or when the end-to-end system test is not valid.
• Alarm Sense (refer to Section 7.7.2 on page 7-57)
The Fusion Wideband Main Hub can monitor 3 external alarm contacts. Each port
can be configured for normally-open (NO) or normally-closed (NC) contacts. The
interface expects a set of floating contacts, and an external voltage source is not
required for this interface. Use AdminBrowser to monitor the port status.
Table 7-8 lists the alarm types, equipment to which the Fusion Wideband Main Hub
is connected, cable(s) used, and the faults and warnings that are detected.

Using a Base Station to Monitor Fusion Wideband
NOTE: The BTS must be configured, by the carrier, for contact closure monitoring
prior to connecting a Fusion Wideband Main Hub to it.
When you connect a BTS to Fusion Wideband, the Fusion Wideband Main Hub is the
output of the alarms (alarm source) and the BTS is the input (alarm sense), as shown
in Figure 7-31. An interface cable is required between the daisy-chain cable and the
BTS. Because BTS alarm interface pinouts and Fusion Wideband-to-BTS distances
vary, this cable is often custom and wired on-site. Refer to Section 3.2.1 for Alarm
Contact details (Normally Closed).
Figure 7-31 Using a BTS to Monitor Fusion Wideband

Use AdminBrowser to enable the Fusion Wideband system for “alarm sense” when
connecting to the contact closure of Unison Main Hubs or other external alarms (refer
to Set Contact Sense Properties in the AdminBrowser User Manual).
Using Fusion Wideband to Monitor Unison
When you connect Unison to Fusion Wideband, the Fusion Wideband Main Hub is
the input of the alarms (alarm sense) and the Unison is the output (alarm source), as
shown in Figure 7-33. The input alarm sense needs to be set to normally closed (NC).
Figure 7-33 Using Fusion Wideband to Monitor Unison
Unison supports only faults. You must use the Alarm Sense Adapter Cable (refer to
page 7-60) to interface the daisy-chain cable to Fusion Wideband. The adapter cable
is required because it translates the Unison fault pinout to the sense input pins on the
Fusion Wideband Main Hub.

1. The RAU’s LINK and ALARM LEDs should blink (green/red) on power up.
• If the LEDs do not blink on power up, replace the RAU.
2. After several seconds both LEDs should change to green, which indicates that the
unit has been successfully replaced, there is communication with the Hub, and the
RAU band is correct.
a. If the LINK LED remains green and the ALARM LED remains red, verify that
the RAU model is correct for the intended frequency band.
– Disconnect the cable and then reconnect it once; doing this more than once
will not change the result.
b. If both LEDs still don’t change to green, use AdminBrowser to determine the
exact nature of the fault and see a recommendation of how to correct it.
c. If both LEDs turn red (after 90 seconds), the Hub has terminated communica-
tions.

9.3.1 Troubleshooting Using AdminBrowser
Use AdminBrowser software to determine the current faults and warnings for all of
the units in the system. To troubleshoot, start with the Fusion Wideband Main Hub’s
faults AND warnings, then proceed to each of the Expansion Hubs, finishing with
each of the RAUs.
NOTE: AdminBrowser v1.00 displays events (faults, warnings, or status
messages) depending on your view preference. To change your view prefer-
ence, refer to Section 3.3.2, “View Preference,” on page 3-10.
System Troubleshooting
Using AdminBrowser, click SYSTEM INFORMATION, then click GET FAULTS, WARNINGS
AND STATUSES. This gives the present status of the system, depending upon View
Preferences for all components.
Faults usually impact service; warnings may impact service; status messages contain
information that should not be ignored, but indicate conditions that do not generally
impact service.
NOTE: System commands can take longer to execute compared to compo-
nent commands.
NOTE: This RAU icon indicates there is fault on the RAU. This icon
indicates a disconnected device. You cannot request status on a discon-
nected device.
9.3.1.1 Troubleshooting Recommendations
Some actions that you can take, depending on the device fault or warning include, are
as follows:
a. Hardware faults on Expansion Hub.
– Try swapping fiber with another Expansion Hub at the Main Hub.
– Try cleaning the fiber and the fiber ports with alcohol foam tip swab and
compressed air. See Section , “To clean the fiber ports:,” on page -2.
– Power cycle the Expansion Hub.

Troubleshooting
b. Under Alarms, click CLEAR ALL DISCONNECTS at the Fusion Wideband Main
Hub.
c. Power cycle the Fusion Wideband Main Hub.
d. RAU hardware faults. Try moving a working CATV to the suspect port and
verifying that the RAU comes up OK.
e. Try isolating the system components:
– Check to see if the whole system is effected or a portion of the system.
– If the whole system is effected, disconnect the DAS system from the RF
source and see if the RF source is working.
– Continue to isolate by disabling portions of the system. Under System Con-
figuration, click SHOW SYSTEM TREE and select a component. Then click SET
OUT OF SERVICE/SET IN SERVICE.
9.3.1.2 Fault/Warning/Status Indications
Once all of the units are powered on and the cable connections are made, the faults
from each unit can be requested using AdminBrowser. Start with the Fusion Wide-
band Main Hub and work downstream.
Resolve all faults first and then check the warnings. Take appropriate action to
resolve the faults, as indicated in the following tables. In cases where there is more
than one possible cause, they are listed from the “most likely” to the “least likely”
cause. Actions are listed in the order that they should be performed; not all actions
may need to be done.
NOTE: If you have a red STATUS LED without a fault message, it probably
indicates that the unit is locked out.
Refer to Appendix C for tables containing Fault, Warning, and Status messages and
their meanings.
9.3.2 Troubleshooting Using LEDs
The following troubleshooting guide is from the perspective that all Fusion Wideband
equipment is installed, their cables are connected, and they are powered on; it is
assumed that the system was operating normally before the problem to be diagnosed
occurred.
Always use AdminBrowser, if possible, to troubleshoot the system. The Fusion Wide-
band Main Hub and Expansion Hub LEDs are for backup troubleshooting. The RAU
LEDs probably will not provide additional information for troubleshooting.

CONFIDENTIAL D-620616-0-20 Rev A
NOTE: For Canadian customers, the Manufacturer’s rated output power1 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: This device complies with Part 15 of the FCC Rules. Operation is
subject to the following two conditions: (1) this device may not cause harm-
ful interference, and (2) this device must accept any interference received,
including interference that may cause undesired operation.
B.2 Human Exposure to RF
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 transmitters operating
at frequencies between 300 kHz and 100 GHz. Limits have been set for portable,
mobile, and fixed equipment. LGC products fall in the category of fixed equipment;
products intended to be permanently secured and exposures are evaluated for dis-
tances greater than 20cm (7 7/8”). Portable devices fall into exposures of less than
20cm, are SAR evaluations are used.
Antenna gain is restricted to 1.5 W ERP (2.49 W EIRP) in order to satisfy RF expo-
sure compliance requirements. If higher than 1.5 W ERP, routine MPE evaluation is
needed. The antennas should be installed to provide at least 20 cm from all persons to
satisfy MPE requirements of FCC Part 2, 2.1091.
Basic MPE evaluation is performed by taking the maximum power output of the
equipment, the gain of the antenna to be used, and distance from the antenna, refer-
enced in FCC OET Bulletin 65 “Evaluation Compliance with FCC Guidelines for
Human Exposure to Radio Frequency for Electric Fields”.
LGC products transmit well below the FCC power density limits. FCC defines power
output limits
at 20cm distance for various frequency ranges:
• Over 300 mHz to 1.5 GHz the limit is determined by frequency/1500
1. “Manufacturer’s rated output power” refers to Fusion Wideband’s downlink P1dB. The power per carrier tables take into
account this power reduction for multiple carriers.
Help Hot Line (U.S. only): 1-800-530-9960 B-3
D-620616-0-20 Rev A CONFIDENTIAL
• Above 1.5 GHz the limit is 1mW/cm2
The basic equation for determining power density is:
S = PG / 4πR2
Where S is power density in mW/cm2
PG, the transmitted power from the antenna identified as EIRP (Equivalent Isotropi-
cally Radiated Power), is the product of power output of device and antenna gain, in
mW.
R is the distance of interest from the antenna.
Typical Installation Example:
Assuming an antenna is placed on a 10 foot ceiling, for a person 6 feet tall, the dis-
tance from antenna to body is 4 feet (112 cm.).
For a PCS 1900 remote unit, the maximum power output, according to the power
table in Section 6.3 Maximum Output Power per Carrier on page 6-4, is 16.5 dB.
Assuming a 7 dBi antenna is used, PG in the equation is equal to 23.5 dB (224 mW)
EIRP.
Using S = PG/4πR2
S = 224/(4x3.14) x (122)2 = 0.001 mW/cm2
Also, assuming a minimum distance of 20 cm according to FCC regulations”
S = 224/(4 x 3.14) x (20)2 = 0.04 mW/cm2

Once all of the units are powered on and the cable connections are made, the faults
from each unit can be requested using AdminBrowser. Start with the Fusion Wide-
band Main Hub and work downstream.
Resolve all faults first and then check the warnings. Take appropriate action to
resolve the faults, as indicated in the following tables. In cases where there is more
than one possible cause, they are listed from the “most likely” to the “least likely”
