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 components and the associ-ated 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: 800 MHz, 850 MHz, 900 MHz, 1800 MHz, 1900 MHz, 2100 MHz• Voice Protocols: AMPS, TDMA, CDMA, GSM/EGSM• Data Protocols: CDPD, EDGE, GPRS, WCDMA, CDMA2000, 1xRTT, EV-DO, and Paging
System Overview2-2 InterReach Fusion Installation, Operation, and Reference ManualCONFIDENTIAL D-620TBD-0-20 Rev AThe Fusion system supports two 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 MHzBoth bands support all protocols.Fusion remote access units contain combinations of Band 1 and Band 2 frequencies to support various world areas, that is 850 MHz/1900MHz for North America or 900 MHz/2100 MHz for Europe and Asia. Refer to Figure 4-3 on page 4-6 for a specific list of these RAU frequency combinations.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 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 74 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 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.

All events occurring in a system, defined as a Fusion Main Hub and all of its associ-ated 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 con-nections to the RJ-45 port.

Using AdminBrowser, you can perform the following:• Configure a newly installed system• Change system parameters• Perform an end-to-end system test• Query system status from any standard web browser (Internet Explorer) running on your PC/laptop system.Refer to the AdminBrowser User Manual (D-620607-0-20 Rev A) for information about installing and using AdminBrowser software.2.3.1 System Monitoring and ReportingEach Fusion Hub in the system constantly monitors itself and its downstream RAUs for internal fault and warning conditions. The results of this monitoring are stored in memory and compared against new results.When a 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 Hub’s RJ-45 port. Passive antennas connected to the RAUs are not monitored automatically. Per-form 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.

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)
Overview6-2 InterReach Fusion Installation, Operation, and Reference ManualCONFIDENTIAL D-6206TBD-0-20 Rev AThe design goal is always a stronger signal than the mobile phone needs. It includes inherent factors which affect performance.• RF source (base station or BDA), 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 6-13.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 goalSatisfactory 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 6-13.• 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 6-13.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 equip-ment you need. The actual path loss slope that corresponds to the specific RF environment inside the building can also be determined empirically by perform-ing 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.
Help Hot Line (U.S. only): 1-800-530-9960 6-3D-6206TBD-0-20 Rev A CONFIDENTIALDownlink RSSI Design Goal6. 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 6-37.Once you know the quantities of Fusion equipment to be used, you can determine the accessories (combiners/dividers, surge suppressors, repeaters, attenuators, cir-culators, 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 LGC Wireless Customer Portal at LGCWireless.com for on-line dimensioning and design tools.6.2 Downlink RSSI Design GoalWireless 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 GSMA protocol are shown below for a 95% area cov-erage confidence factor.Downlink design goals on the order of –85 dBm are typical for protocols, such as GSM and iDEN. 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.Noise Power10 Log (KT)+10 Log (200 KHz); K=1.38X10–23, T=300 degrees Kelvin–121 dBmWireless Handset Noise Figure 8 dBRequired SNR 9 dBMultipath Fade Margin95% Reliability for Rician K=6 dB6dBLog-normal Fade Margin95% Area/87% Edge Reliability for 35 dB PLS and 9 dB Sigma10 dBBody Attenuation + 3 dBDownlink RSSI Design Goal (PDesignGoal)Signal level received by wireless handset at edge of coverage area–85 dBm
Maximum Output Power per Carrier6-4 InterReach Fusion Installation, Operation, and Reference ManualCONFIDENTIAL D-6206TBD-0-20 Rev A6.3 Maximum Output Power per CarrierThe 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’s maximum output power recommenda-tions.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).

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.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.Table 6-5 UMTS Power per CarrierNo. ofCarriersPower per Carrier (dBm)WCDMA115.0211.038.046.555.064.073.0Note: measurements taken with no baseband clipping.Note: Operation at or above these output power levels may prevent Fusion from meet-ing RF performance specifications or FCC Part 15 and EN55022 emissions require-ments.

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 12 carriers with a recommended maximum power per carrier of 7.5 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 propa-gation loss should be no more than 95.5 dB (7.5 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 6-24.5. Path Loss Slope: For a rough estimate, Table 6-10, “Estimated Path Loss Slope for Different In-Building Environments” on page 6-16, 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 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.

Link Budget Analysis6-24 InterReach Fusion Installation, Operation, and Reference ManualCONFIDENTIAL D-6206TBD-0-20 Rev A6.6 Link Budget AnalysisA 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 StandardsThe 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 6-18 provides link budget considerations for narrowband systems.

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 inde-pendently 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 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 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 com-bined) 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 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.Protocol Signal Bandwidth Thermal NoiseTDMA 30 kHz –129 dBmGSM 200 kHz –121 dBmiDEN 25 kHz –130 dBm

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.Table 6-18 Link Budget Considerations for Narrowband Systems (continued)Consideration Description

Help Hot Line (U.S. only): 1-800-530-9960 6-29D-6206TBD-0-20 Rev A CONFIDENTIALLink Budget Analysis6.6.3 Elements of a Link Budget for CDMA StandardsA 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 6-21 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. The open-loop power control equation isPTX + PRX = –73 dBm (for Cellular, IS-95)Table 6-21 Distribution of Power within a CDMA SignalChannel Walsh Code Number Relative Power LevelPilot 0 20% –7.0 dBSync 32 5% –13.3 dBPrimary Paging 1 19% –7.3 dBTraffic 8–31, 33–63 9% (per traffic channel) –10.3 dB
Link Budget Analysis6-30 InterReach Fusion Installation, Operation, and Reference ManualCONFIDENTIAL D-6206TBD-0-20 Rev APTX + 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 6-22 on page 6-30). The differ-ence between these power levels, ∆P, can be estimated by comparing the power radi-ated from the RAU, Pdownink, to the minimum received signal, Puplink, at the RAU:∆P = Pdownink + Puplink + 73 dBm (for Cellular)∆P = Pdownink + Puplink + 76 dBm (for PCS)It’s a good idea to keep –12 dB < ∆P < 12 dB.Table 6-22 provides link budget considerations for CDMA systems.Table 6-22 Additional Link Budget Considerations for CDMAConsideration DescriptionMultipath 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 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 dBInformation Rate This is simply 10log10(9.6 Kbps) = 40 dB for rate set 110log10(14.4 Kbps) = 42 dB for rate set 2Process 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 1PG = 10log10(1.25 MHz / 14.4 Kbps) = 19 dB rate set 2Note that the process gain can also be expressed as 10log10 (CDMA bandwidth) minus the information rate.

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 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.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) – PGNoise Rise On the uplink, the noise floor is determined not only by the Fusion 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.Table 6-22 Additional Link Budget Considerations for CDMA (continued)Consideration Description

The connector losses associated with mating to these connectors is accounted for in the design and should not be included as ele-ments 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 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.
Help Hot Line (U.S. only): 1-800-530-9960 6-37D-6206TBD-0-20 Rev A CONFIDENTIALConnecting a Main Hub to a Base Station6.8 Connecting a Main Hub to a Base StationThe Fusion system supports 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, 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 main hub may be damaged.If, in an area covered by Fusion, a mobile phone indicates good signal strength but consistently has difficulty completing calls, it is possible that the attenuation between Fusion 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 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 AttenuationThe 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. Setting the attenuation on the uplink is a trade-off between keeping the noise and maximum sig-nal levels transmitted from Fusion 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 by itself, although it can be significantly worse.
Connecting a Main Hub to a Base Station6-38 InterReach Fusion Installation, Operation, and Reference ManualCONFIDENTIAL D-6206TBD-0-20 Rev AA good rule of thumb is to set the uplink attenuation such that the noise level out of Fusion is within 10 dB of the base station’s sensitivity.6.8.2 RAU Attenuation and ALCThe RAU attenuation and ALC are set using the AdminBrowser Advanced RAU Set-tings command.Embedded within the uplink RF front-end of each Fusion RAU band is an ALC cir-cuit. This ALC circuit protects the Fusion system from overload and excessive inter-modulation 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 of the Fusion has an uplink ALC circuit that operates as a feed-back 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 6-2.1. 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.

This is accom-plished by selecting the check boxes in the Advanced RAU Settings dialog box. There are two check boxes: one for setting the downlink attenuation and another for setting the uplink attenuation for each band.•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, thenwhere PLS is path loss slope (dBm).Input SignalLevelActivationLevel-30dBmReleaseLevel-45dBmOutput SignalLevelTimeHoldPhaseReleasePhaseAttackPhase12345PLSdBdd/1010'=

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 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 system’s configured and adjacent frequency bands. This setting is seldom used.

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 RAUsMount all RAUs in the locations marked on the floor plans.Considerations:• Install 800 iDEN and 850/1900 MHz RAUs so that their antennas will be separated by enough space to reduce signal interference between the 800 and 850 bands. Refer to Section , “800/850 MHz Isolation Requirements,” on page 7-25 for rec-ommended distance between antennas.• 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 against the mounting surface.Installing Passive AntennasRefer to the manufacturer’s installation instructions to install passive antennas.LocationPassive 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.800/850 MHz Isolation RequirementsWhen deploying any RF system, give special attention to preventing receiver block-ing or desensitization by out-of-band transmitters. Typically, sharp filters in the receiver front-end will reduce the interfering transmitters to tolerable levels. In select cases, the interferers may occupy a frequency band that is directly adjacent to the receiving band and cannot be adequately rejected by filtering. The only recourse in
Fusion Installation Procedures7-26 InterReach Fusion Installation, Operation, and Reference ManualCONFIDENTIAL D-620TBD-0-20 Rev Athese situations is to provide sufficient isolation by physically separating the interfer-ing transmitters and receivers.iDEN occupies spectrum at both 800 MHz and 900 MHz (Tx:806–825/Rx:851–870 and Tx:896–901/Rx:935–940), while the Cellular A and B carriers share a single 850 MHz block (Tx:869–894/Rx:824–849). The combination of these frequency bands, 800/900 MHz iDEN and 850 MHz Cellular, result in uplink (BTS receive) bands that are adjacent to downlink (BTS transmit) bands. Figure 7-5 depicts these nearly con-tiguous bands, with arrows indicating the interfering downlink and receiving uplink bands.Figure 7-5 800/850 MHz SpectrumInstallation of an in-building distributed antenna system (DAS) to provide coverage for both 800/900 MHz iDEN and 850 MHz Cellular must account for these down-link-to-uplink interference issues and provide adequate isolation. LGC offers the following guidelines toward achieving the proper amount of isolation when deploying LGC Wireless Unison DAS products.Figure 7-6 Guideline for Unison RAU Antenna Placement800 MHz iDEN Downlink and 850 MHz Cellular UplinkA 2 MHz frequency gap (851 – 849 MHz) separates the 800 iDEN downlink and 850 Cellular uplink frequency bands. Because of this narrow spacing, 800 iDEN down-link intermodulation products may fall within the 850 Cellular uplink band. In addi-tion, 800 iDEN downlink signals near the lower edge of the band at 851 MHz may cause the 850 Cellular uplink automatic level control (ALC) circuitry in the RAU to engage and thereby reduce uplink gain.850 850

Because of this narrow spacing, 850 Cellular downlink intermodulation products may fall within the 900 iDEN uplink band. In addition, 850 Cellular downlink signals near the upper edge of the band at 894 MHz may cause the 900 iDEN uplink ALC to engage and thereby reduce uplink gain.To prevent either of these conditions, use the following guidelines:• In-band 850 Cellular intermodulation products < -90dBm• Upper frequency 850 Cellular signals < –30dBm for UnisonGiven a typical DAS configuration (6 CDMA carriers for Unison, omni-directional antennas, line of sight), these guidelines translate to an antenna spacing (d2) of 8-14 meters.Connecting the Antenna to the RAUConnect 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.Connecting the CATV CableConsiderations:• Verify that the cable has been tested and the test results are recorded.

Ownership of LGC Wireless equipment carries no automatic right of use. 7.5 Splicing Fiber Optic CableThe 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.7.5.1 Fusion SplicesUsing 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 PigtailBefore you begin, make sure the fusion splicer is set to the proper mode (that is, sin-gle- or multi-mode).To fusion splice the fiber optic cable to the SC/APC pigtail: Option A1. 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.

Troubleshooting9-4 InterReach Fusion Installation, Operation, and Reference ManualCONFIDENTIAL D-620TBD-0-20 Rev A9.3.1 Troubleshooting Using AdminBrowserUse AdminBrowser software to determine the current faults and warnings for all of the units in the system. To troubleshoot, start with the Fusion 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 TroubleshootingUsing 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 RecommendationsSome 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.b. Under Alarms, click CLEAR ALL DISCONNECTS at the Fusion Main Hub.

Help Hot Line (U.S. only): 1-800-530-9960 B-3D-620TBD-0-20 Rev A CONFIDENTIALB.2 Human Exposure to RFThe U.S. Federal Communications Commission (FCC) has adopted limits of human exposure to radio frequency (RF) emissions from portable or fixed RF systems that are regulated by the FCC. The exposure limits on the incident electric and magnetic fields and power densities are based on ANSI/IEEE and NCRP RF Safety Guidelines. The limits are also prescribed in terms of the mass-normalized rates of internal energy absorption by tissues (specific absorption rates or SARs) which should not exceed 0.08 W/kg as averaged over the whole body and 1.6 W/kg for any 1-g of tissue.Similarly, the U.K. National Radiological Protection Board (NRPB) and the Interna-tional Commission on Non-Ionizing Radiation Protection (ICNIRP) have both estab-lished guidelines for maximum RF exposure levels that are likely to not pose health risks. For the general public, ICNIRP recommends maximum exposure levels of 2.0 W/kg for any 10-g of tissue. This recommendation is 5 times lower than that of NRPB.The specific absorption rate (SAR) was measured for a radiated power of 20 dBm (100 mW) which is the maximum radiated for both of the antennas. The highest SAR regions for each of the antennas for separation distances of 0, 1, 2, and 3 cm to the tis-sue-simulant model were determined in the first instance by using a coarser sampling with a step size of 8.0 mm over three overlapping scan areas for a total scan area of 8.0 × 9.6 cm. After identifying the regions of the highest SAR for each of the cases, the SAR distributions were measured with a resolution of 2 mm in order to obtain the peak 1 cm 3 or 1-g SAR.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.

A-13The following tables contain messages for all versions of firmware, but all messages are not displayed by a given firmware version.C.1 Fault Messages Reported by HubsFaults indicate service-impacting conditions and should be given immediate atten-tion.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 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.
