InterReach Fusion Wideband System Description
SYSTEM OVERVIEW
InterReach Fusion Wideband is an intelligent fiber optics/CATV, multi‐band (frequencies)
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 larger buildings.
Fusion Wideband provides RF characteristics designed for large public and private facilities such
as campus environments, airports, shopping malls, subways, convention centers, sports venues,
and so on. Fusion Wideband uses microprocessors to enable key capabilities such as
software‐selectable band settings, automatic gain control, ability to incrementally adjust
downlink/uplink gain, end‐to‐end alarming of all components and the associated cable
infrastructure, and a host of additional capabilities.
The Fusion Wideband system supports major wireless standards and air interface protocols in
use around the world, including:
•
Frequencies: 700 MHz, 800 MHz, 850 MHz, 1700 MHz, 1800 MHz, 1900 MHz, 2100 MHz, 2500
MHz, 2600 MHz.
•
Voice Protocols: AMPS, TDMA, CDMA, GSM/EGSM, WCDMA, LTE, WiMAX
•
Data Protocols: CDPD, EDGE, GPRS, WCDMA, CDMA2000, 1xRTT, EV‐DO, LTE, Paging, and
WiMAX
The Fusion Wideband system supports three configurable bands:
•
Band 1 in 60 MHz and can be configured for 700 MHz, 800 MHz, 1900 MHz, 2100 MHz, 2500
MHz, or 2600 MHz
•
Band 2 in 75 MHz and can be configured for 1700 MHz, 1800 MHz, 1900 MHz, 2100 MHz,
2500 MHz, or 2600 MHz
Both bands support all protocols.
Fusion Wideband remote access units (RAUs) contain combinations of Band 1, Band 2, and
Band 3 frequencies to support various world areas. These frequencies are 1800 MHz/2100
MHz for Europe, the Middle East, and Asia, or
800 MHz/850 MHz/1900 MHz for North America. Refer to Table 4 on page 19 for a specific
list of supported RAUs.
•
Band 3 (only used for North America: FSN‐W2‐808519‐1, FSN‐W2‐7021‐1, FSN‐W2‐7070‐1,
FSN‐W2‐7575‐1, FSN‐W4‐702121‐1‐HP, FSN‐W4‐752121‐1‐HP, and
FSN‐W5‐851921‐1‐HP). For example, the FSN‐W2‐808519‐1 RAU Band 3 is a 25 MHz
sub‐band of the 60 MHz Band and Band 1 is an 18 MHz sub‐band of the 60 MHz Band.
The Fusion Wideband system has the following key system features
•
Multi‐Band, supports two or more 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

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 downlink
and uplink.
– RAU:

RAU uplink and downlink gain can be independently attenuated 0 or 10 dB.

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.
•

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‐2‐1P, FSN‐W2‐MH‐3‐1P,
FSN‐W3‐MH‐1P, FSN‐W4‐MH‐1P, and FSN‐W5‐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 remove the front
panel fiber port plate, since doing so will void the product warranty.

InterReach Fusion Wideband System Description
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 automatically reported to the Main Hub. The Main Hub
monitors system status and communicates 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 connections to
the RJ‐45 port.
Use AdminBrowser to configure or monitor a local or remote Fusion Wideband system.

System OA&M Capabilities Overview
AdminBrowser OA&M software runs on the Fusion Wideband Main Hub microprocessor and
communicates to its downstream Expansion Hubs and associated RAUs. Using AdminBrowser,
you can perform the following from any standard web browser (Internet Explorer) running on
your PC/laptop system:
•
Configure a newly installed system
•
Change system parameters
•
Perform an end‐to‐end system test
•
Query system status
Refer to the AdminBrowser User Manual (D‐620607‐0‐20) for information about installing and
using AdminBrowser software.
System Monitoring and Reporting
Each Fusion Wideband Main Hub in the system constantly monitors itself, its Expansion 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 warning alarm.
Faults are also indicated locally by red status LEDs. Both faults and warnings 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 monitored automatically. Perform a System Test
to retrieve status information about antennas.
Using AdminBrowser, you can install a new system or new components, change system
parameters, and query system status. Figure 2‐4 illustrates how the system reports its status to
AdminBrowser.

Using Alarm Contacts
You can connect the DB‐9 female connector on the rear panel of the Fusion Wideband Main Hub
to a local base station or to a daisy‐chained series of Fusion and/or FlexWave Focus systems.
When you connect FlexWave Focus or a BTS to the Fusion Wideband, the Fusion Wideband Main
Hub outputs the alarms (alarm source) and FlexWave Focus or the BTS receives the alarms
(alarm sense). This is described in Section 7.7.1 on page 7‐59.

System Connectivity
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 adding an extra antenna for additional
coverage, potentially as easy as pulling an extra CATV cable.

Fusion Wideband Main Hub
FUSION WIDEBAND MAIN HUB OVERVIEW
The Fusion Wideband Main Hub (shown in Figure 8) distributes up to three individual (Band 1, 2,
and 3) downlink RF signals from a base station, repeater, or FlexWave 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. Band 3 (or RF3) goes to a 25
MHz sub‐band of the 60 MHz band and is functional only with the 800/850/1900, 700/AWS,
700/700 (Upper C) MIMO, 700/700 (Lower ABC) MIMO, 700 ABC/AWS HP/AWS HP, 700
UC/AWS HP/AWS HP, and 850/1900 HP/AWS HP RAU. The system installs in a 19" equipment
rack and is usually co‐located with the RF source in a telecommunications closet.
Downlink Path: The Main Hub receives up to 3 individual (Band1, 2, or 3) downlink RF signals from a base station, repeater,
or FlexWave Focus system using 50 Ohm coaxial cable. It converts the signals to IF then to optical and sends them to up to
four Expansion Hubs using fiber optic cable.
The Main Hub also sends OA&M communication to the Expansion Hubs using the fiber optic cable. The Expansion Hubs,
in turn, communicate the OA&M information to the RAUs using CATV cable.

Uplink Path: The Main Hub receives uplink optical signals from up to four Expansion Hubs using fiber optic cables. It converts
the signals to IF then to RF and sends them to the respective Band1, 2, or 3 base station, repeater, or FlexWave Focus system
using 50 Ohm coaxial cable.
The Main Hub also receives status information from the Expansion Hubs and all RAUs using the fiber optic cable.
Figure 8. Main Hub in a Fusion Wideband System
Figure 9 on page 31 shows a detailed view of the major RF and optical functional blocks of the
Main Hub.
The Fusion Wideband One Port Main Hub (PNs: FSN‐W1‐MH‐2‐1P, FSN‐W2‐MH‐3‐1P,
FSN‐W3‐MH‐1P, FSN‐W4‐MH‐1P, and FSN‐W5‐MH‐1P) configuration is a cost reduced version of
the Fusion Wideband Main Hub and supports only one Expansion Hub (up to 8 RAUs).

Fusion Wideband Main Hub Front Panel
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 signals 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, including
fiber distribution panels.
Communications RS‐232 Serial Connector
•
Remote Monitoring—Use a standard serial cable to connect a modem to the 9‐pin D‐sub
male serial connector for remote monitoring or configuring. The cable typically has a DB‐9
female and a DB‐9 female connector. Refer “DB‐9 to DB‐9 Null Modem Cable” on page 201 to
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
“TCP/IP Cross‐Over Cable” on page 200 for the cable pinout.
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 AdminBrowser.
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 “Troubleshooting Using LEDs” on page 186 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 communication problems within the system, the LEDs may
provide additional information that is not available using AdminBrowser.

Fusion Wideband Expansion Hub
EXPANSION HUB OVERVIEW
The Expansion Hub acts an interface between the Main Hub and the Remote Access Unit(s) by
converting optical signals to electrical signals and vice versa, as shown in Figure 13. It also
supplies control signals and DC power to operate the Remote Access Unit(s) as well as passing
status information from the RAUs to the Main Hub.
Downlink Path: The Expansion Hub receives downlink (Band 1, 2, and 3) 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.

Expansion Hub Overview
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 copper center conductor CATV
cable with quality type F connectors that use captive centerpin connectors. Refer to “Appendix
A: Cables and Connectors” on page 191 for approved cables and connectors.
Manufacturing RS‐232 Serial Connector
Console Port
This console port is only used by TE manufacturing test purposes. DO NOT CONNECT ANYTHING
TO IT.
Local Monitoring
Use a crossover Ethernet cable (PN‐4069‐ADB) to directly connect a laptop or PC to the RJ‐45
female connector for local monitoring or configuring the Expansion Hub and associated RAUs
using the AdminBrowser‐EH resident software. The cable typically has a RJ‐45 male connector on
both ends. Refer to “TCP/IP Cross‐Over Cable” on page 200 for the cable pinout and the
AdminBrowser manual.
Optical Fiber Uplink/Downlink Connectors
The optical fiber uplink/downlink port transmits and receives optical signals between the
Expansion Hub and the Main Hub using industry‐standard SMF or MMF cable. The fiber port has
two female SC/APC connectors:
•
Optical Fiber Uplink Connector—This connector (labeled UPLINK) is used to transmit
(output) uplink optical signals to the Main Hub.
•
Optical Fiber Downlink Connector—This connector (labeled DOWNLINK) is used to receive
(input) downlink optical signals from the Main Hub.
CAUTION!
To avoid damaging the Expansion Hub’s fiber connector ports, use only SC/APC fiber cable
connectors. Additionally, use only SC/APC fiber connectors throughout the fiber network,
including fiber distribution panels. This is critical for ensuring system performance.

Remote Access Unit
OVERVIEW
The Remote Access Unit (RAU) is an active transceiver that connects to an Expansion Hub using
industry‐standard CATV cable, which delivers RF signals, configuration information, and
electrical power to the RAU.
An RAU passes converted 1F to RF (Downlink) and converted RF to 1F (Uplink) signals between
an Expansion Hub and an attached passive antenna where the signals are transmitted to wireless
devices as shown in Figure 17.
Downlink Path: The RAU receives downlink IF signals from a Fusion Wideband Hub using 75 Ohm CATV cable. It converts
the signals to RF and sends them to a passive RF antenna using 50 Ohm coaxial cable. Also, the RAU receives configuration
information from the Fusion Wideband Hub using the 75 Ohm CATV cable.

Designing a Fusion Wideband Solution
OVERVIEW
Designing a Fusion Wideband solution is a matter of determining coverage and capacity needs.
This requires the following steps:
Determine the wireless service provider’s requirements; refer to “Downlink RSSI
Design Goal” on page 64.
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)
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 equipment if
possible.
Determine the downlink power per carrier from the RF source through the DAS; refer
to “Maximum Output Power per Carrier” on page 65.
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 carriers increases.
Develop an RF link budget; refer to “Estimating RF Coverage” on page 82.
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.

Overview
Determine the in‐building environment; refer to “Estimating RF Coverage” on page 82.
•
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 cubicles)
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
“Estimating RF Coverage” on page 82.
Use the path loss slope (PLS), which gives a value to the RF propagation characteristics 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 Wideband equipment you need. The
actual path loss slope that corresponds to the specific RF environment inside the building can
also be determined empirically by performing an RF site‐survey of the building. This involves
transmitting a calibrated tone for a fixed antenna and making measurements with a mobile
antenna throughout the area surrounding the transmitter.
Determine the items required to connect to the base station; refer to “Connecting a
Main Hub to a Base Station” on page 101.
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 station.
The individual elements that must be considered in designing a Fusion Wideband solution are
explained in the following sections.

Designing a Fusion Wideband Solution
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 figures 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 process 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 multipath 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
coverage confidence factor.

Signal level received by wireless handset at edge of coverage area
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.

Maximum Output Power per Carrier
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 attenuated 0 or 10 dB.
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.
CAUTION!
Exceeding the maximum input power may cause permanent 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 a Fusion Wideband Solution
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:
Design the initial coverage with a maximum power per carrier for four RF carriers. This will
likely result in additional RAUs.
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.

System Gain
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 independently attenuated
by 0 or 10 dB 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 6‐18.

Designing a Fusion Wideband Solution
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, consequently, 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 generally downlink‐limited, this approach is
applicable in the majority of deployments.

Estimating RF Coverage
You can calculate the distance, d, corresponding to the maximum allowable path loss using
equations introduced in the following sections.
Equation 2—Path Loss Equation
In‐building path loss obeys the distance power law in Equation 2:
PL = 20log10(40f/c) + 10nlog10(d/d0) + Xs
where:
•
PL is the path loss at a distance, d, from the antenna
•
d = the distance expressed in meters
•
d0 = 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
•
Xs = a normal random variable that depends on partition material and geometries 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 66 provides estimates of signal loss for some RF barriers1.

Estimating RF Coverage
Equation 4—Path Loss Equation
By setting the path loss to the maximum allowable level (PL = APL), Equation 3 can be used to
estimate the maximum coverage distance of an antenna connected to an RAU, for a given
frequency and type of in‐building environment, which is Equation 4.
d = 10^((APL ‐ 20log10(4/c))/PLS)
For reference, Table 69 through Table 75 on page 87 show the distance covered by an antenna for
various in‐building environments, in which the following assumptions were made:
•
Path Loss Equation 4
•
6 dBm output per carrier at the RAU output
•
3 dBi antenna gain
•
RSSI design goal is equal to –85 dBm, which is typical for narrowband protocols, but not for
spread‐spectrum protocols.

Example Design Estimate for an 1900 MHz CDMA Application
Design goals:
•
PCS (1920 MHz = average of the lowest uplink and the highest downlink frequency 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.
Power Per Carrier: The tables in “Maximum Output Power per Carrier” on page 65 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.
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.
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 propagation 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 signal 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 “Link
Budget Analysis” on page 89.

Designing a Fusion Wideband Solution
Path Loss Slope: For a rough estimate, Table 68 on page 84 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 “Equation 2—Path Loss Equation” on page 83 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.
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.
•
4 antennas per floor × 16 floors = 64 RAUs
•
64 RAUs ÷ 8 = 8 Expansion Hubs, as there is a maximum of 8 RAUs per Expansion Hub
•
8 Expansion Hubs ÷ 4 = 2 Main Hubs, as there is a maximum of 4 Expansion Hubs per Main
Hub
Check that the fiber and CATV cable distances are as recommended. If the distances differ, use
the tables in Section 6.4, “System Gain,” on page 6‐16 to determine 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, additional 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.

Link Budget Analysis
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.
CAUTION!
Exceeding the maximum input power of 1W (+30 dBm) could cause permanent damage to the
Main Hub.
NOTE:
Visit the TE customer portal for the on‐line Link Budget Tool; see “TE Customer Portal” on page 3.
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 analyzes 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 76 on page 90 provides link budget considerations for narrowband systems.

Designing a Fusion Wideband Solution
Table 76.
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
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 “Maximum Output Power per Carrier” on page 65.
This includes all losses: cable, attenuator, splitter/combiner, and so forth.
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 “Connecting a
Main Hub to a Base Station” on page 101 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 radiator) 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 effective
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 represents 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 diffraction.
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 coverage
if the signal level is, on average, above this level over 95% of the area covered, for example.

Link Budget Analysis
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 reception, 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 79 shows an example.
Table 79.

Traffic

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 channels 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‐handoff 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.
The open‐loop power control equation is as follows:
for Cellular, IS‐95:
PTX + PRX = –73 dBm
for PCS, J‐STD‐008:
PTX + PRX = –76 dBm
where PTX is the mobile’s transmitted power and PRX is the power received by the mobile.

Designing a Fusion Wideband Solution
The power level transmitted under closed‐loop power control is adjusted by the base station to
achieve a certain Eb/N0 (explained in Table 6‐34 on page 6‐32). The difference between these
power levels, P, can be estimated by comparing the power radiated from the RAU, Pdownink, to the
minimum received signal, Puplink, at the RAU:
for Cellular:
P = Pdownink + Puplink + 73 dBm
for PCS:
P = Pdownink + Puplink + 76 dBm
It’s a good idea to keep –12 dB < P < 12 dB.
Table 80 provides link budget considerations for CDMA systems.
Table 80.
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 carrier,
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 (representing 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
determine 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
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
signal-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 multipath
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

Additional Link Budget Considerations for CDMA (Cont.)
Consideration
Description
Noise Rise
On the uplink, the noise floor is determined not only by the Fusion Wideband system, but also by the number
of mobiles that are transmitting. This is because when the base station attempts to de-spread a particular
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.
Other CDMA Issues
Other CDMA issues are as follows:
•
Never combine multiple sectors (more than one CDMA signal at the same frequency) into a
Fusion Wideband system. The combined CDMA signals will interfere 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 important 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.

Considerations for Re‐Radiation (Over‐the‐Air) Systems
Fusion Wideband can be used to extend the coverage of the outdoor network by connecting to a
roof‐top donor antenna pointed toward an outdoor base station. Additional 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 TE application notes for re‐radiation
applications.

Designing a Fusion Wideband Solution
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 single‐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
CONNECTING A MAIN HUB TO A BASE STATION
The Fusion Wideband system supports up to three RF sources: one for Band 1, one for Band 2 and
one for Band 3. 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 Wideband Main Hub bands to its base station, the following
equipment may be required:
•
circulators
•
filter diplexers
•
directional couplers
•
combiner/splitters
•
attenuators
•
coax cables
•
connectors.
In addition, use the following considerations to achieve optimal performance:
•
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.
•
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 attenuation 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 provide 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.

Designing a Fusion Wideband Solution
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 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.
RAU Attenuation and ALC
The RAU attenuation and ALC are set using the AdminBrowser Edit Unit Properties 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 following sequence describes the operation of the
ALC circuit, as illustrated in Figure 6‐2.
The RF signal level into either Band of the RAU rises above the activation threshold (–30
dBm), causing that ALC loop to enter into the attack phase.
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.
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.
The RF signal level drops below the release threshold (–45 dBm) and the ALC loop enters the
release phase.
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.

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 0 or 10 dB for each RAU band (1, 2 or 3). 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 sensitivity is reduced and mobile phones in the area of that
RAU band will have to transmit 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 operating. 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.

Designing a Fusion Wideband Solution
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 factor 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).
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 functionality 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 frequency bands. This setting is
seldom used.
