InterReach Fusion 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 smaller buildings.
Fusion 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 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 componen ts and the asso ci­ated cable infrastructure, and a host of additional capabilities.
The Fusion system supports major wireless standards and air interface protocols in use around the world, including:
• Frequencies: 700 MHz, 800 MHz, 850 MHz, 900 MHz, 1800 MHz, 1900 MHz, 2100 MHz
• Voice Protocols: AMPS, TDMA, CDMA, GSM/EGSM,WCDMA, iDEN, LTE
InterReach Fusion Installation, Operation, and Reference Manual 2-1
D-620610-0-20 Rev F CONFIDENTIAL
System Overview
• Data Protocols: CDPD, EDGE, GPRS, WCDMA, CDMA2000, 1xRTT, EV-DO, LTE, and Paging
The Fusion system supports three configurable bands:
• Band 1 in 35 MHz and can be configured for 850 MHz, or 900 MHz.
• Band 2 in 75 MHz and can be configured for 1800 MHz, 1900 MHz, or 2100 MHz
Both bands support all protocols. Fusion remote access units contain combinations of Band 1, Band 2, and Band 3
frequencies to support various world areas, that is 800 MHz/900 MHz/1900MHz for North America or 900 MHz/2100 MHz and 900 MHz/1800 MHz for Europe and Asia. Refer to Figure 2 -7 on page 2-8 for a specific list of these RAU fre­quency combinations.
• Band 3 (only used for the North American FSN-809019-2, FSN-2-708519-1, and FSN-2-758519-1 RAU) whose Band 3 (in the case of the FSN-809019-2 RAU) is a 6 MHz sub-band of the 35 MHz Band with Band 1 being an 18 MHz sub-band of the 35 MHz Band.
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 noi se fig u re.
High downlink composite power and low uplink noise figure enables support of a large number of channels and larger coverage footprint per antenna.
Softwar e 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 150 meters for RG-59 cable; 170 meters for RG-6; 275 meters for RG-11 using CommScope 2065V , 2279V, and 2293K cables.
Flexible RF conf iguration 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 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.
OA&M capabilities, including fault isolation to the field replaceable unit, report-
ing of all fault and warning conditions, and user-friendly web browser user inter­face OA&M software package.

2.3 System OA&M Capabilities Overview

InterReach Fusion 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 Main Hub, Expansion Hub, and Remote Access Unit) and the cabling infrastructure, is available. All events occurring in a system, defined as a Fusion 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.

2.3.1 System Monitoring and Reporting

Each Fusion 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.

2.4 System Connectivity

The double star architecture of the Fusion 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.

3.1 Fusion Main Hub Overview

The Fusion Main Hub (shown in Figure 3-1) distributes up to three individual (Band 1, 2, or 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 is a multi-band system. One RF source (Band 1 or RF1) goes to the 35 MHz band and the other RF source (Band 2 or RF2) goes to the 75 MHz band. Band 3 (or RF3) goes to a sub-band of the 35 MHz band and is functional only with the 800/900/1900 , 700 ABC/850/1900, and 700 UC/850/1900 RAU. The system installs in a 19" equipment rack and is usually co-located with the RF source in a telecommu­nications closet.

5.1 RAU 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 5-1.

6.1 Overview

Designing a Fusion solution is a matter of determining coverage and capacity needs. This requires the following steps:
1. Determine the wireless service provider’ s r equirements: Refer to Section6.2,
“Downlink RSSI Design Goal,” on page 6-3.
The following information is typically provided by the service provid er:
• 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)
InterReach Fusion Installation, Operation, and Reference Manual 6-1
D-620610-0-20 Rev F CONFIDENTIAL
Overview
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.
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’s RF performance. Power per carrier decreases as the number of carriers increases.
3. Develop an RF link budget: Refer to Section 6.5, “Estimating RF Coverage,”
on page 6-15.
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 envir onment: Refer to Section 6.5, “Estimating RF
Coverage,” on page 6-15.
• 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, “Estimat ing RF Coverage,” on page 6-15.
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 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.

CONFIDENTIAL D-620610-0-20 Rev F
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 6-39.
Once you know the quantities of Fusion 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 solution are explained in the following sections.
NOTE: Access the TE Customer Portal at http://www.te.com/adc for on-line dimensioning and design tools.

6.2 Downlink RSSI Design Goal

Wireless service providers t ypically 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.

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’s maximum output power recommenda­tions.
WARNING: 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 for Capacity Growth
Fusion 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 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.

D-620610-0-20 Rev F CONFIDENTIAL
System Gain
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 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 150 meters for CommScope PN 2065V.
• For RG-6 cable 170 meters for CommScope PN 2279V.
• For RG-11 cable 275 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 6-9 and Table 6-10.

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, are generally downlink-limited, this approach is applicable in the majority of deployments.

6.5.3 Examples of Design Estimates

Example Design Estimate for an 850 MHz TDMA Application
1. Design goals:
• Cellular (859 MHz = average of the lowest uplink and the highest downlink frequency in 800 MHz Cellular band)
• TDMA provider
• 12 TDMA 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 850 MHz TDMA table (on page 6-5) indicates that Fusion can support 10 carriers with a recommended maximum power per carrier of 7.0 dBm. The input power should be set to the desired output power minus the system gain.
3. Building information:
• Eight floor building with 9,290 sq. meters (100,000 sq. ft.) per floor; total 74,322 sq. meters (800,000 sq. ft.).
• Walls are sheetrock construction , suspended ceiling tiles.
• Antennas used will be omni-directional, ceiling mounted.
• Standard office environment, 50% hard wall offices and 50% 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 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 Section 6.6 on page 6-26.
5. Path Loss Slope: For a rough estimate, Tabl e 6-14, “Estimated Path Loss Slope for
Different In-Building Environments” o n page 6-18, shows that a building with 50% hard wall offices and 50% cubicles, at 859 MHz, has an approximate path loss slope (PLS) of 37.6. Given the RF link budget of 95.5 dB, the distance of coverage from each RAU will be 52 meters (170.6 ft). This corresponds to a coverage area of 8,494 sq. meters (91,425 sq. ft.) per RAU (refer to Sec t i o n 6 . 5 . 1 f o r d e t a i l s on path loss estimation). For this case we assumed a circular radiation pattern, th ough t he actual area covered depends upon the pattern of the antenna and the obstructio ns in the facility.

Estimating RF Coverage
Equipment Required: Since you know the building size, you can now estimate the Fusion equipment quantities that will be needed. Before any RF levels are tested in the building, you can estimate that two 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. 2 antennas per floor × 8 floors = 16 RAUs b. 16 RAUs ÷ 8 (maximum 8 RAUs per Expansion Hub) = 2 Expansion Hubs c. 2 Expansion Hubs ÷ 4 (maximum 4 Expansion Hubs per Main Hub) = 1 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 6-12 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 equipment quantities required for the building. The site survey measures the RF losses within the building to determine the actual PLS, which are used in the final path loss formula to determine the actual requirements of the Fusion system.

Example Design Estimate for an 1900 MHz CDMA Application
1. 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
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 (on page 6-10) indicates that Fusion 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 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.

Link Budget Analysis

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.

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 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 6-22 provides link budget considerations for narrowband systems.

Table 6-22 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
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 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 alone. Refer to Section 6.8 for ways to inde­pendently set the uplink and downlink attenuations between the base station and Fusion.
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 ef fect ive 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 effec-
tive noise floor plus a certain C/I ratio).
Fusion Noise Figure This is Fusion’s uplink noise figure, which varies depending on the number of Expansion Hubs and
RAUs, and the frequency band. Fusion’s uplink noise figure is specified for a 1-1-8 configuration. Thus, the noise figure for a Fusion 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 bandwidt h (B W).
Thermal noise power = –174 dBm/Hz + 10Log(BW).
Required C/I ratio For each wireless standard, a certain C/I (carrier to interference) r ati o 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
The maximum power the mobile can transmit (power transmitte d at highest power level setting).
Power 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 ma rgin accounts for the possibility of destructive multipath interference. In RF site surveys the effect s of multipath fading are typically not accounted for because such fading is averaged out over power level samples taken over many locations.

Consideration Description
Log-normal Fade Margin
This margin adds an allowance for RF shadowing due to objects obstructing the direct pa th 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.
