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,WCDMA, iDEN Data Protocols: CDPD, EDGE, GPRS, WCDMA, CDMA2000, 1xRTT, EV-DO, and Paging D-620610-0-20 Rev B InterReach Fusion Installation, Operation, and Reference Manual 2-1 CONFIDENTIAL System Overview 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 fre-

quency combinations. Band 3 (only used for the North American FSN-809019-1 RAU) whose Band 3 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 noise figure. High downlink composite power and low uplink noise figure enables support of a large number of channels and larger coverage footprint per antenna. Software configurable Main and Expansion Hubs allow the frequency bands to be configured in the field. Either single-mode or multi-mode fiber can be used, supporting flexible cabling alternatives (in addition to standard CATV 75 Ohm cabling). You can select the cabling type to met the resident cabling infrastructure of the facility and unique building topologies. Extended system reach. Using single-mode fiber, fiber runs can be a long as 6 kilometers (creating a total system wingspan of 12 kilometers). Alternatively, with multi-mode fiber, fiber runs can be as long as 500 meters. Standard 75 Ohm CATV cable, can be run up to 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. 2-2 CONFIDENTIAL InterReach Fusion Installation, Operation, and Reference Manual D-620610-0-20 Rev B System Hardware Description VSWR check on RAU reports if there is a disconnected antenna.

19" rack-mountable Main Hub (connects to up to 4 Expansion Hubs, except for the One Port Main Hub configuration that supports 1 Expansion Hub) Converts RF signals to optical IF on the downlink; optical IF-to-RF on the uplink Microprocessor controlled (for alarms, monitoring, and control) Auto-configurable bands Simplex interface to RF source Periodically polls all downstream RAUs for system status, and automatically reports any fault or warning conditions 19 rack mountable Expansion Hub (connects to up to 8 Remote Access Units) Optical signal conversion to electrical on the downlink; electrical to optical on the uplink Microprocessor controlled (for alarms, monitoring, and control) Software configurable band (based on commands from the Main Hub) Supplies DC power to RAUs over CATV cable. Remote Access Unit (RAU) Converts IF signals to RF on the downlink; RF-to-IF on the uplink Microprocessor controlled (for alarms, monitoring, and control) Multi-band protocol independent, frequency specific units The minimum configuration of a Fusion 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 com-

bined to provide larger configurations. NOTE: The Fusion One Port Main Hub (PN: FSN-1-MH-1P) configuration is a cost reduced version of the Fusion Main Hub and supports only one D-620610-0-20 Rev B Help Hot Line (U.S. only): 1-800-530-9960 2-3 CONFIDENTIAL System Hardware Description Expansion Hub (up to 8 RAUs). The Fusion One Port Main Hub is software locked to 1 port 2 fiber ports. Additional ports are disabled internally.

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 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 Hubs front panel RJ-45 port connects directly to a PC (for local Ethernet access). The Main Hubs 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. Figure 2-3 Three Methods for OA&M Communications Use AdminBrowser to configure or monitor a local or a remote Fusion system.

The results of this monitoring are stored in memory and compared against new results. When a Main or Expansion Hub detects a change in status, it reports a fault or warn-

ing alarm. Faults are also indicated locally by red status LEDs. Both faults and warn-

ings are reported to AdminBrowser software and displayed on a PC/laptop connected to the Main Hubs RJ-45 port. Passive antennas connected to the RAUs are not moni-

tored automatically. Perform a System Test to retrieve status information about antennas. Using AdminBrowser, you can install a new system or new components, change sys-

tem parameters, and query system status. Figure 2-4 illustrates how the system reports its status to AdminBrowser. Figure 2-4 System Monitoring and Reporting Fusion Main Hub AdminBrowser Fusion Expansion Hub AdminBrowser RAU RAU The Main Hub queries status of each Expan-

sion Hub and each RAU and compares it to previously stored status. If a fault is detected, LEDs on the front panel turn red. The Expansion Hub queries the status of each RAU and compares it to the previously stored status. If a fault is detected, LEDs on the front panel turn red. Each RAU passes its status to the Hub. If a fault is detected, the ALARM LED is red. If no fault is detected, the LED is green. PC/Laptop running a standard web browser Use a standard browser to communi-

This is described in Section 7.7.1 on page 7-55. 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.

The Main Hub also combines uplink signals from the associ-

ated 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 6 MHz sub-band of the 35 MHz band and is functional only with the 800/900/1900 RAU. The system installs in a 19" equipment rack and is usually co-located with the RF source in a telecommunications closet.

This requires the following steps:

1. Determine the wireless service providers 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) D-620610-0-20 Rev B InterReach Fusion Installation, Operation, and Reference Manual 6-1 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 equip-

ment if possible. 2. Determine the downlink power per carrier from the RF source through the DAS: Refer to Section 6.3, Maximum Output Power per Carrier, on page 6-4. The maximum power per carrier is a function of modulation type, the number of RF carriers, signal quality issues, regulatory emissions requirements, and Fusions 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 6-14. 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 RAUs antenna to the wireless handset. allowable path loss = power per carrier + antenna gain design goal Satisfactory performance can be expected as long as path loss is below this level. 4. Determine the in-building environment: Refer to Section 6.5, Estimating RF Coverage, on page 6-14. 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 buildings 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 6-14. 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 6-2 CONFIDENTIAL InterReach Fusion Installation, Operation, and Reference Manual D-620610-0-20 Rev B Downlink RSSI Design Goal for a fixed antenna and making measurements with a mobile antenna throughout the area surrounding the transmitter. 6. Determine the items required to connect to the base station: Refer to Section 6.8, Connecting a Main Hub to a Base Station, on page 6-38. 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 Goal Wireless service providers typically provide a minimum downlink signal level and an associated confidence factor when specifying coverage requirements. These two fig-

ures of merit are a function of wireless handset sensitivity and margins for fading and body loss. Wireless handset sensitivity is the weakest signal that the handset can pro-

cess reliably and is a combination of the thermal noise in the channel, noise figure of the handset receiver front end and minimum required SNR. Fade margins for multi-

path fading (fast or small-scale) and log-normal shadow fading (slow or large-scale) are determined by the desired confidence factor, and other factors. Downlink RSSI design goal calculations for the GSM protocol are shown below for a 95% area cover-

age confidence factor.

Wireless service providers may choose a higher level to ensure that in-building signal dominates any macro signal that may be leaking into the building. 6.3 Maximum Output Power per Carrier The following tables show the recommended maximum power per carrier out of the RAU 50 Ohm Type-N connector for different frequencies, protocols, and numbers of carriers. These maximum levels are dictated by RF signal quality and regulatory emissions issues. In general, as the number of RF carrier increases, the maximum power per carrier decreases. If these levels are exceeded, signal quality will be degraded and/or regulator requirements will be violated. The maximum input power to the Hub is determined by subtracting the system gain from the maximum output power of the RAU. System gain is software selectable from 0 dB to 15 dB in 1 dB steps. Additionally, both the uplink and downlink gain of each RAU can be reduced by 10 dB in 1 dB steps. When connecting a Hub to a base station or repeater, attenuation on the downlink is typically required to avoid exceeding Fusions 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). 6-4 CONFIDENTIAL InterReach Fusion Installation, Operation, and Reference Manual D-620610-0-20 Rev B Maximum Output Power per Carrier CDMA WCDMA 15 11 8 6.5 5.0 16 13 11 10.0 9.0 8.0 7.5 7.0 6.3.1 850 MHz Cellular Cellular Power per Carrier No. of Carriers AMPS 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 20 30 16.5 16.5 16.5 13.5 12.0 10.5 9.5 8.5 8.0 7.0 7.0 6.5 6.0 5.5 5.5 5.0 4.0 2.0 Power per Carrier (dBm) TDMA 16.5 16.5 15.0 13 11.5 10.5 9.5 8.5 8.0 7.5 7.0 6.5 6.5 6.0 5.5 5.5 4.5 2.5 GSM 16.5 13.5 11.5 10.0 9.0 8.5 8.0 7.5 7.0 6.5 6.5 6.0 6.5 5.5 5.0 5.0 4.5 3.0 EDGE 16.5 13.5 11.5 10.0 9.0 8.5 8.0 7.5 7.0 6.5 6.5 6.0 5.5 5.5 5.0 5.0 4.0 2.0 Note: Operation at or above these output power levels may prevent Fusion from meeting RF performance specifications or FCC Part 15 and EN55022 emissions requirements.

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. 6-10 CONFIDENTIAL InterReach Fusion Installation, Operation, and Reference Manual D-620610-0-20 Rev B System Gain 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 indepen-

dently decreased by 10 dB in one dB steps 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 6-6 and Table 6-7.

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:

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 94.5 dB (6.5 dBm + 3 dBi + 85 dBm) over 95% of the area being covered. It is important to note that a design goal such as 85 dBm is usually derived taking into account multipath fading and log-normal shadowing characteristics. Thus, this design goal will only be met on average over 95% of the area being covered. At any given point, a fade may bring the sig-

nal level underneath the design goal. Note that this method of calculating a link budget is only for the downlink path. For information to calculate link budgets for both the downlink and uplink paths, refer to Section 6.6 on page 6-25. 5. Path Loss Slope: For a rough estimate, Table 6-11, Estimated Path Loss Slope for Different In-Building Environments on page 6-17, 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.

Given the RF link budget of 94.5 dB, the distance of coverage from each RAU will be 30.2 meters (99 ft). This corresponds to a coverage area of 2,868 sq. meters (30,854 sq. ft.) per RAU (refer to Section 6.5.1 for details on path loss estimation).

The end result can often be stated as a design goal in which the coverage is determined by the maximum distance from each RAU before the signal strength falls beneath that goal. One key feature of the link budget is the maximum power per carrier explained in Section 6.3. While the maximum power per carrier is important as far as emissions and signal quality requirements are concerned, it is critical that the maximum signal into the Main Hub never exceed 1W (+30 dBm). Composite power levels above this limit will cause damage to the Main Hub. WARNING: Exceeding the maximum input power of 1W (+30 dBm) could cause permanent damage to the Main Hub. NOTE: Visit the LGC Wireless customer portal at LGCWireless.com for the on-line Link Budget Tool. 6.6.1 Elements of a Link Budget for Narrowband Standards The link budget represents a typical calculation that might be used to determine how much path loss can be afforded in a Fusion 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 6-19 provides link budget considerations for narrowband systems. D-620610-0-20 Rev B Help Hot Line (U.S. only): 1-800-530-9960 6-25 CONFIDENTIAL Link Budget Analysis Consideration BTS Transmit Power Attenuation between BTS and Fusion Antenna Gain BTS Noise Figure Fusion Noise Figure Thermal Noise Table 6-19 Link Budget Considerations for Narrowband Systems Description The power per carrier transmitted from the base station output 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 inde-

pendently set the uplink and downlink attenuations between the base station and Fusion. The radiated output power includes antenna gain. For example, if you use a 3 dBi antenna at the RAU that is transmitting 0 dBm per carrier, the effective radiated power (relative to an isotropic radi-

ator) is 3 dBm per carrier. 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). This is Fusions uplink noise figure, which varies depending on the number of Expansion Hubs and RAUs, and the frequency band. Fusions 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 Hubs RAU ports are not used. This is the noise level in the signal bandwidth (BW). Thermal noise power = 174 dBm/Hz + 10Log(BW). Protocol TDMA GSM iDEN Signal Bandwidth 30 kHz 200 kHz 25 kHz Thermal Noise 129 dBm 121 dBm 130 dBm Required C/I ratio Mobile Transmit Power Multipath Fade Margin 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. The maximum power the mobile can transmit (power transmitted at highest power level setting). 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. 6-26 CONFIDENTIAL InterReach Fusion Installation, Operation, and Reference Manual D-620610-0-20 Rev B Link Budget Analysis Table 6-19 Link Budget Considerations for Narrowband Systems (continued) Consideration Log-normal Fade Margin Body Loss Minimum Received Signal Level Description 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. This accounts for RF attenuation caused by the users head and body. 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.

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 6-22 shows an example. Table 6-22 Distribution of Power within a CDMA Signal Channel Pilot Sync Primary Paging Traffic Walsh Code Number Relative Power Level 0 32 1 20%

19%

831, 3363 9% (per traffic channel) 7.0 dB 13.3 dB 7.3 dB 10.3 dB 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 is PTX + PRX = 73 dBm (for Cellular, IS-95) 6-30 CONFIDENTIAL InterReach Fusion Installation, Operation, and Reference Manual D-620610-0-20 Rev B Link Budget Analysis PTX + PRX = 76 dBm (for PCS, J-STD-008) where PTX is the mobiles 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 6-23 on page 6-31). 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) Its a good idea to keep 12 dB < P < 12 dB. Table 6-23 provides link budget considerations for CDMA systems. Table 6-23 Additional Link Budget Considerations for CDMA Consideration Multipath Fade Margin Power per car-

rier, downlink Description 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 5S/km. If the difference in fiber lengths to Expansion Hubs with overlapping coverage areas produces at least 1 chip (0.8S) delay of one path relative to the other, then the multipaths signals can be resolved and processed independently by the base stations rake receiver. A CDMA signal traveling through 163 meters of MMF cable is delayed by approximately one chip. 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 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.

Its the CDMA equivalent of sig-

nal-to-noise ratio (SNR). This figure depends on the mobiles receiver and the multipath environment. For example, the multipath delays inside a building are usually too small for a rake receiver in the mobile (or base station) to resolve and coherently combine multipath components. However, if artificial delay can be introduced by, for instance, using different lengths of cable, then the required Eb/No is lower and the mul-

tipath fade margin in the link budget can be reduced in some cases. If the receiver noise figure is NF (dB), then the receive sensitivity (dBm) is given by:

Psensitivity = NF + Eb/No + thermal noise in a 1.25 MHz band PG

= NF + Eb/No 113 (dBm/1.25 MHz) PG Noise Rise On the uplink, the noise floor is determined not only by the Fusion system, but also by the number of mobiles that are transmitting. This is because when the base station attempts to de-spread a particular mobiles 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:

Hand-off Gain 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. 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 Never combine multiple sectors (more than one CDMA signal at the same fre-

quency) into a Fusion 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 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. 6-32 CONFIDENTIAL InterReach Fusion Installation, Operation, and Reference Manual D-620610-0-20 Rev B Link Budget Analysis 6.6.4 CDMA Link Budget Analysis for a Microcell Application Table 6-24 CDMA Link Budget Analysis: Downlink Line Downlink Transmitter a. b. c. d. e. f. g. h. i. j. k. l. m. n. o. p. q. r. s. t. u. v. w.

Additional consider-

ations for such an application of Fusion are:

Sizing the gain and output power requirements for a bi-directional amplifier

(repeater). Ensuring that noise radiated on the uplink from the in-building system does not cause the outdoor base station to become desensitized to wireless handsets in the outdoor network. Filtering out signals that lie in adjacent frequency bands. For instance, if you are providing coverage for Cellular B-band operation it may be necessary to filter out the A, A and A bands which may contain strong signals from other outdoor base stations. Further information on these issues can be found in LGC Wireless application notes for re-radiation applications. 6-36 CONFIDENTIAL InterReach Fusion Installation, Operation, and Reference Manual D-620610-0-20 Rev B Optical Power Budget 6.7 Optical Power Budget Fusion 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 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. D-620610-0-20 Rev B Help Hot Line (U.S. only): 1-800-530-9960 6-37 CONFIDENTIAL Connecting a Main Hub to a Base Station 6.8 Connecting a Main Hub to a Base Station The Fusion 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 asso-

ciated 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 bands base station, the uplink system gain can be increased to as much as 15 dB to prevent a reduction in the overall system sensitivity. 6.8.1 Uplink Attenuation The attenuation between the Main Hubs uplink port and the associated bands 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 6-38 CONFIDENTIAL InterReach Fusion Installation, Operation, and Reference Manual D-620610-0-20 Rev B Connecting a Main Hub to a Base Station inputs. This SNR can not be better than the SNR of Fusion 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 is within 10 dB of the base stations sensitivity. 6.8.2 RAU Attenuation and ALC The RAU attenuation and ALC are set using the AdminBrowser Edit Unit Proper-

ties screen. Embedded within the uplink RF front-end of each Fusion 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 (1, 2, or 3) of a Fusion RAU has an uplink ALC circuit that operates as a feedback loop. A power detector measures the level of each bands uplink RF input and if that level exceeds 30 dBm, an RF attenuator is activated. The level of attenuation is equal to the amount that the input exceeds 30 dBm. The fol-

lowing sequence describes the operation of the ALC circuit, as illustrated in Figure 6-2. 1. The RF signal level into either Band of the RAU rises above the activation thresh-

old (30 dBm), causing that ALC loop to enter into the attack phase. 2. During the attack phase, the ALC loop increases the attenuation (0 to 30 dB) until the detector reading is reduced to the activation threshold. The duration of this attack phase is called the attack time. 3. After the attack time, the ALC loop enters the hold phase and maintains a fixed attenuation so long as the high-level RF signal is present. 4. The RF signal level drops below the release threshold (45 dBm) and the ALC loop enters the release phase. 5. During the release phase, the ALC loop holds the attenuation for a fixed period then quickly releases the attenuation. An important feature of the ALC loop is that in Step 3, the attenuation is maintained at a fixed level until the signal drops by a significant amount. This prevents the ALC loop from tracking variations in the RF signal itself and distorting the waveform modulation.

This is accomplished by selecting the appropriate UPLINK and/or DOWNLINK attenua-

tion for each RAU band in the Edit Unit Properties screen of AdminBrowser for the selected RAU. Downlink Attenuation: The downlink attenuator provides a mechanism to reduce the signal strength from an RAU band. For instance, this could be for an RAU band located near a window in a tall building that is causing excessive leakage to the macro-network. In such a case it is important to attenuate the downlink only. The uplink should not be attenuated. If the uplink is attenuated, the uplink sensitiv-

ity is reduced and mobile phones in the area of that RAU band will have to trans-

mit at a higher power. This would increase interference to the outdoor network from such mobiles. Uplink Attenuation: The uplink attenuator attenuates environmental noise picked up by an RAU band located in an area where heavy electrical machinery is operat-

ing. In such environments the electrical noise can be quite high and it is useful to reduce the amount of such noise that gets propagated through the distributed antenna system. Attenuating the uplink of an RAU band located in areas of high electrical noise helps preserve the sensitivity of the rest of the system. The effect of activating the uplink or downlink attenuators is to reduce the coverage area of the adjusted RAU band. The coverage radius will be reduced by roughly a fac-

tor of 2. More specifically, if d is the coverage distance without attenuation and d is the coverage radius with the attenuation, then d d

This func-

tionality is required to prevent RF signal compression caused by a single or multiple wireless devices in very close proximity to the RAU band. Compression causes signal degradation and, ultimately, dropped calls and data errors, and should be prevented. Two settings are available to optimize UL ALC performance:

Multiple Operators: Use when more than one operator and/or protocol is present in the Fusion systems 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 systems configured and adjacent frequency bands. This setting is seldom used.

Allow clearance of 76 mm (3 in.) front and rear, and 51 mm (2 in.) on both sides for air circulation. No top or bottom clearance is required. D-620610-0-20 Rev B Help Hot Line (U.S. only): 1-800-530-9960 7-11 CONFIDENTIAL Fusion Installation Procedures Figure 7-1 Flush Mounting Bracket Detail Consideration:

The Fusion Main Hub is shipped with #10-32 mounting screws. Another common rack thread is #12-24. Confirm that the mounting screws match the racks threads. Insert spring nuts into rack where needed or use existing threaded holes. To install the Hub in a rack:

1. 2. Place the Hub into the rack from the front. 3. Align the flange holes with the spring nuts installed in Step 1. 4. 5. Tighten the mounting screws. Insert the mounting screws in the appropriate positions in the rack. Installing an Optional Cable Manager in the Rack Using the screws provided, fasten the cable manager to the rack, immediately above or below the Main Hub. Installing a Main Hub Using the 12 Wall-Mounted Rack (PN 4712) Considerations:

The rack-mounting brackets on the Fusion Main Hub must be moved to the recessed mounting position (shown in Figure 7-2) to allow for the required 76 mm

(3 in.) rear clearance. 7-12 CONFIDENTIAL InterReach Fusion Installation, Operation, and Reference Manual D-620610-0-20 Rev B Fusion Installation Procedures The maximum weight the bracket can hold is 22.5 kg (50 lbs). The bracket is designed to accommodate a Fusion Main Hub (12 lbs.) or an Expan-

sion Hub (14.5 lbs.). The wall mount bracket should be securely mounted to wall, using the four key slot mounting holes on the bracket. Using the Wall Rack-Mounting Option You can flip the rack mounting brackets, as shown in Figure 7-2, so the hub can be mounted 76 mm (3 in.) forward in the rack. Figure 7-2 Bracket Detail For Wall Mount Rack (PN 4712) To install the Hub to the wall-mounted rack:

1. Attach the wall bracket (PN 4712) to wall the using #10 Pan Head wood screws, 1-1/2 minimum length for mounting in wood studs or 3/4thick plywood. The bracket must be positioned so that the Hub will be in a horizontal position when it is installed. (Refer to Figure 7-2.) NOTE: If wall stud spacing of 16 is not available, LGC recommends that 3/4 plywood be pre-installed to the wall. You can then attach the bracket to the plywood using the wood screws. 2. Remove both of the rack mounting brackets from the Hub. 3. Reattach each of the rack mounting brackets to the recessed wall mount position. 4. Install the Hub in the rack using the rack mounting screws.

Before connecting the fiber cables, confirm that their optical loss does not exceed the 3 dB optical budget. If you are using fiber distribution panels, confirm that the total optical loss of fiber cable, from the Main Hub through distribution panels and patch cords to the Expansion Hub, does not exceed the optical budget. Make sure the fiber cables connectors are SC/APC (angle-polished). Using any other connector type will result in degraded system performance and may damage the equipment. (You can use an SC/APC pigtail if the fiber cables connectors are not SC/APC. Refer toFusion Splicing of Fiber and Pigtail on page 7-42. Or, you can change the fibers connector to SC/APC.) NOTE: Observe all Fiber Port Safety Precautions listed in Section 7.2.3 on page 7-4. D-620610-0-20 Rev B Help Hot Line (U.S. only): 1-800-530-9960 7-15 CONFIDENTIAL Fusion Installation Procedures To clean the fiber ports:

You can clean the Hubs fiber ports using canned compressed air or isopropyl alcohol and foam tipped swabs. Considerations:

If using compressed air:

The air must be free of dust, water, and oil. Hold the can level during use. If using isopropyl alcohol and foam tipped swabs:

Use only 98% pure or more alcohol Procedure using compressed air:

1. Remove the ports dust cap. 2. Spray the compressed air away from the unit for a few seconds to clean out the nozzle and then blow dust particles out of each fiber port. Procedure using isopropyl alcohol:

1. Remove the connectors dust cap. 2. Dip a 2.5mm lint-free, foam-tipped swab in isopropyl alcohol and slowly insert the tip into the connector. 3. Gently twist the swab to clean the port. Insert a dry swab into the port to dry it. 4. Additionally, you can use compressed air after the alcohol has completely evapo-

rated. To clean the fiber ends:

Be sure that the fiber cables SC/APC connectors are clean and free of dust and oils. You need lint-free cloths, isopropyl alcohol, and compressed air 1. Moisten a lint-free cloth with isopropyl alcohol. 2. Gently wipe the fiber end with the moistened cloth. 3. Using a dry lint-free cloth, gently wipe the fiber end. 4. Spray the compressed air away from the connector for a few seconds to clean out the nozzle and then use it to completely dry the connector. To test the fiber cables:

Perform cable testing and record the results. Test results are required for the final As-Built Document. To connect the fiber cables:

The fiber cable is labeled with either 1 or 2, or is color-coded. In addition to these labels, you should add a code that identifies which port on the Main Hub is being 7-16 CONFIDENTIAL InterReach Fusion Installation, Operation, and Reference Manual D-620610-0-20 Rev B Fusion Installation Procedures used and which Expansion Hub the cables are intended for. This differentiates the connectors for proper connection between the Main Hub and Expansion Hubs. For example:

First pair to Main Hub port 1: 11 (uplink), 12 (downlink);

Second pair to Main Hub port 2: 21 (uplink), 22 (downlink);

Third pair to Main Hub port 3: 31 (uplink), 32 (downlink); and so on. NOTE: The Fusion One Port Main Hub (PN: FSN-1-MH-1P) configuration is a cost reduced version of the Fusion Main Hub and supports only one Expansion Hub (up to 8 RAUs). If the fiber jumper is labeled with 1 or 2:

1. Connect 1s to UPLINK ports on the Main Hub. 2. Connect 2s to DOWNLINK ports on the Main Hub. 3. Record which cable number and port number you connected to UPLINK and DOWNLINK. This information is needed when connecting the other end of the fiber cable to the Expansion Hubs fiber ports. The fiber port LEDs should be off, indicating that the Expansion Hub(s) are not connected. If the fiber jumper is color-coded (for example, blue or red):

1. Connect blue to UPLINK ports on the Main Hub. 2. Connect red to DOWNLINK ports on the Main Hub. 3. Record which color and port number you connected to UPLINK and DOWNLINK. This information is needed when connecting the other end of the fiber cable to the Expansion Hubs fiber ports. The fiber port LEDs should be off, indicating that the Expansion Hub(s) are not connected.

AC Powered Main Hub To connect AC power to a Main Hub:

1. Connect the AC power cord to the Main Hub. 2. Plug the power cord into an AC power outlet. DC Powered Main Hub and Expansion Hub WARNING: The protective earth connection should be connected before proceeding with power connections. Confirm the DC power source is powered off during installation. Damage to hubs may result if power is connected improperly. The DC powered Main Hub and Expansion Hub are intended to be powered by a

+48VDC power source. The hubs are designed for 14AWG to 6AWG wire size connections. Use only UL listed AWM wire, rated 600V and 90 degrees C. If wires larger than 6AWG are needed from the DC power source, follow local codes for reducing the wire size at hub connection point. Follow local codes for routing of power cables to power source. The unit should be connected to a DC branch circuit breaker. A suitable discon-

nect device must be provided in the DC branch, either a circuit breaker or switch, that can be employed to disconnect power to the system during servicing. To connect DC power to a Main Hub or Expansion Hub:

Insert the +48VDC wire into the compression terminal at the + location. Insert the -48VDC wire into the compression terminal at the - location. 1. Strip 5/8 (16mm) of wire insulation material off each power wire. 2. 3. 4. Bare wire ends should be fully inserted into terminal. 5. Use a flat blade screw driver to fasten the wire inside the compression terminal. 6. For the Protective Ground Wire (Figure 7-5), use 14AWG minimum wire with a

#8-32 stud size ring lug. Figure 7-5 Protective Ground Wire Connection 7-18 CONFIDENTIAL InterReach Fusion Installation, Operation, and Reference Manual D-620610-0-20 Rev B Fusion Installation Procedures WARNING: The warning color code of the power cables depends on the color coding of the DC power source installed at your site.

Connect the AC or DC power as explained in Making Power Connections on page 7-18. 7-28 CONFIDENTIAL InterReach Fusion Installation, Operation, and Reference Manual D-620610-0-20 Rev B Fusion Installation Procedures 2. Turn on the power to the Expansion Hub and check that all the LED lamps are functioning properly. Upon power-up, the LEDs blinks for five seconds as a visual check that they are functioning. After the five-second test:

The POWER and UL STATUS LEDs should be green. If the uplink fiber is not connected, the UL STATUS LED turns red indicating that there is no communication with the Main Hub. The E-HUB STATUS and DL STATUS LEDs should be red. All port LEDs should be off because no RAUs are connected yet. Connecting the Fiber Cables to the Expansion Hub Considerations:

Before connecting the fiber cables, confirm that their optical loss does not exceed 3 dB optical budget. RL is less than -60dB. If fiber distribution panels are used, confirm that the total optical loss of fiber cable, from the Main Hub through distribution panels and patch cords to the Expansion Hub, does not exceed the optical budget. Make sure the fiber cables connectors are SC/APC (angle-polished).Using any other connector type will result in degraded system performance and may damage the equipment. (You can use an SC/APC pigtail if the fiber cables connectors are not SC/APC, refer to Fusion Splicing of Fiber and Pigtail on page 7-42, or replace the connectors.) NOTE: Observe all Fiber Port Safety Precautions listed in Section 7.2.3 on page 7-4. To connect the fiber cables:

The fiber cable is labeled with either 1 or 2, or is color-coded. For proper connection between the Main Hub ports and the Expansion Hub ports, refer to the numbering or color-coded connections you recorded when installing the Main Hub(s). If the fiber jumper is labeled with 1 or 2:

1. Connect 2 to DOWNLINK on Expansion Hub. The DL STATUS LED should turn green as soon as you connect the fiber. If it does not, there is a downlink problem. Make sure you are connecting the correct cable to the port. 2. Connect 1 to UPLINK on Expansion Hub. The UL STATUS LED turns green on the first Main Hub communication. It may take up to 20 seconds to establish communication. The Expansion Hubs E-HUB STATUS LED turns green when the Main Hub sends it the frequency band command. D-620610-0-20 Rev B Help Hot Line (U.S. only): 1-800-530-9960 7-29 CONFIDENTIAL Fusion Installation Procedures If the UL STATUS and E-HUB STATUS LEDs do not turn green/green, check the Main Hub LEDs. Refer to page 7-24, item 2 in Table 7-5. If the fiber jumper is color-coded (for example, blue or red):

1. Connect red to DOWNLINK on Expansion Hub. The DL STATUS LED should turn green as soon as you connect the fiber. If it does not, there is a downlink problem. Make sure you are connecting the correct cable to the port. 2. Connect blue to UPLINK on Expansion Hub. The UL STATUS LED turns green on the first Main Hub communication. It may take up to 20 seconds to establish communication. The Expansion Hubs E-HUB STATUS LED turns green when the Main Hub sends it the frequency band command. If the UL STATUS and E-HUB STATUS LEDs do not turn green/green, check the Main Hub LEDs. See page 7-24, item 2 in Table 7-5. Connecting the 75 Ohm CATV Cables Considerations:

Verify that the cable has been tested and the test results are recorded. This informa-

tion is required for the As-Built Document. Verify that only captive centerpin F connectors are used on the solid copper center conductor CATV cable from CommScope (or equivalent). Verify that the CATV cable is labeled with:

Fusion Expansion Hub port number being used RAU identifier Carrier (for multiple operator systems) To connect the CATV cables:

1. Connect the CATV cables to the F ports according to the labels on the cables. The STATUS LEDs should be off because the RAUs are not connected at the other end of the CATV cable. 2. Record which cable you are connecting to which port (that is, from the label on the cable). This information is required for the As-Built Document. 3. Tie-off the cables or use the optional cable manager to avoid damaging the con-

nectors because of cable strain. 7-30 CONFIDENTIAL InterReach Fusion Installation, Operation, and Reference Manual D-620610-0-20 Rev B Fusion Installation Procedures Troubleshooting Expansion Hub LEDs During Installation All Expansion Hub PORT LEDs with RAUs connected should indicate Green/Red.

nect an antenna that is installed in an outdoor location to an RAU. For outdoor installations, a protective enclosure is required. Installing RAUs Mount all RAUs in the locations marked on the floor plans. Considerations:

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 7-32 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 (containing the mounting holes) against the mounting surface. Installing Passive Antennas Refer to the manufacturers installation instructions to install passive antennas. Location Passive antennas are usually installed below the ceiling. If they are installed above the ceiling, you must consider the additional loss due to the ceiling material when estimating the antenna coverage area. 800/850 MHz Isolation Requirements When 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 7-32 CONFIDENTIAL InterReach Fusion Installation, Operation, and Reference Manual D-620610-0-20 Rev B Fusion Installation Procedures these 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:806825/Rx:851870 and Tx:896901/Rx:935940), while the Cellular A and B carriers share a single 850 MHz block (Tx:869894/Rx:824849). 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 7-19 depicts these nearly con-

tiguous bands, with arrows indicating the interfering downlink and receiving uplink bands. Figure 7-19 800/850 MHz Spectrum 850 850 Installation 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.

Because of this narrow spacing, 800 iDEN down-

link intermodulation products may fall within the 850 Cellular uplink band. In addi-

Lower frequency 800 iDEN signals < 30dBm for Fusion In-band 800 iDEN intermodulation products < -90dBm Given a typical DAS configuration (4 iDEN carriers, omni-directional antennas, line of sight), these guidelines translate to an antenna spacing (d1) of 6 9 meters. 850 MHz Cellular Downlink and 900 MHz iDEN Uplink A 2 MHz frequency gap (896 894 MHz) separates the 850 Cellular downlink and 900 iDEN uplink frequency bands. 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.

ual RAUs do not interfere with each other. The 850/1900 MHz and 800/900/1900 MHz RAUs antennas must be separated by at least 8 meters (26 feet) to assure that the iDEN downlink signals do not interfere with the Cellular uplink signals. 7.4.4 Configuring the System Before the system can operate properly, use AdminBrowser to program the Fusion Main Hub with the frequency bands that are to be distributed. The Hub must be pro-

grammed with the same frequencies as the RAU used. NOTE: The frequency bands should automatically be set on power up and this step should not be required. Considerations:

D-620610-0-20 Rev B Help Hot Line (U.S. only): 1-800-530-9960 7-41 CONFIDENTIAL Splicing Fiber Optic Cable 7.5 Splicing Fiber Optic Cable The fiber cable must have SC/APC connectors for the entire run. If it does not, you can splice a pigtail, which has SC/APC connectors, to the fiber cable. LGC offers two pigtails: one for single-mode fiber (PN 4013SCAPC-3) and one for multi-mode fiber (PN 4012SCAPC-3). LGC Wireless recommends fusion splices because they have the lowest splice loss and return loss. Mechanical splices have higher losses and higher back reflection than fusion splices and are not recommended. Using a fusion splicer involves fusing together two butted and cleaved ends of fiber. The fusion splicer aligns the fibers and maintains alignment during the fusion pro-

cess. Fusion splices have very low loss (typically less than 0.05 dB) and very low back reflection (return loss). Fusion splices should be organized in a splice tray designed to store and protect the splices. Fusion Splicing of Fiber and Pigtail Before you begin, make sure the fusion splicer is set to the proper mode (that is, sin-

gle- or multi-mode). To fusion splice the fiber optic cable to the SC/APC pigtail: Option A 1. Secure both the fiber cable and the SC/APC pigtail in a splice tray that is installed immediately adjacent to the Hub. 2. Prepare the fiber end by cutting back the polyethylene jacket, the kevlar or fiber-

glass strength members, the extruded coating, and the buffer coating in order to expose the bare fiber cladding plus core. Ensure that sufficient slack is maintained in order to be able to reach the fusion splicer. 3. Clean the unclad fiber core using isopropyl alcohol and lint-free wipes. 4. Cleave the unclad fiber to the length prescribed by the fusion splicers specifica-

tion sheets. 5. Repeat steps 2 through 4 for the SC/APC pigtail. 6. Pass the splice sleeve onto the fiber strand. 7. Position both fiber ends in the fusion splicer and complete splice in accordance with the fusion splicers operation instructions. 8. Ensure that the estimated loss for the splice as measured by the fusion splicer is 0.10 dB or better. 9. Slide the fusion splicing sleeve over the point of the fusion splice. 10. Place the sleeve and fused fiber into the fusion splicers heater. 11. Allow time for the splice sleeve to cure. 7-42 CONFIDENTIAL InterReach Fusion Installation, Operation, and Reference Manual D-620610-0-20 Rev B Splicing Fiber Optic Cable 12.

After successfully testing the fiber, plug the SC/APC pigtail into the proper opti-

cal port on the Hub. To fusion splice the fiber optic cable to the SC/APC pigtail: Option B 1. Secure both the fiber cable and the SC/APC pigtail in a splice tray portion of a fiber distribution panel. 2. Prepare the fiber end by cutting back the polyethylene jacket, the kevlar or fiber-

glass strength members, the extruded coating, and the buffer coating in order to expose the bare fiber cladding plus core.

Alarm Source (refer to Section 7.7.1 on page 7-55) The Fusion Main Hub has two alarm contacts, fault (major) and warning (minor). These contacts are normally-closed (NC) and will open when an internal alarm is detected. NOTE: The contact can be changed to normally-open (NO) with Admin-

Browser. This is not recommended since no alarm would be sent if power to the Fusion Main Hub fails. Fault is activated when any faults or disconnects are detected. Warning is activated when any warning conditions are detected except lockout or when the end-to-end system test is not valid. Alarm Sense (refer to Section 7.7.2 on page 7-58) The Fusion Main Hub can monitor 3 external alarm contacts. Each port can be con-

figured for normally-open (NO) or normally-closed (NC) contacts. The interface expects a set of floating contacts, and an external voltage source is not required for this interface. Use AdminBrowser to monitor the port status. Table 7-8 lists the alarm types, equipment to which the Fusion Main Hub is con-

nected, cable(s) used, and the faults and warnings that are detected.

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. 9-4 CONFIDENTIAL InterReach Fusion Installation, Operation, and Reference Manual D-620610-0-20 Rev B Troubleshooting c. Power cycle the Fusion Main Hub. d. RAU hardware faults. Try moving a working CATV to the suspect port and verifying that the RAU comes up OK. e. Try isolating the system components:

Check to see if the whole system is effected or a portion of the system. If the whole system is effected, disconnect the DAS system from the RF source and see if the RF source is working. Continue to isolate by disabling portions of the system. Under System Con-

figuration, click SHOW SYSTEM TREE and select a component. Then click SET OUT OF SERVICE/SET IN SERVICE. 9.3.1.2 Fault/Warning/Status Indications Once all of the units are powered on and the cable connections are made, the faults from each unit can be requested using AdminBrowser. Start with the Fusion Main Hub and work downstream. Resolve all faults first and then check the warnings. Take appropriate action to resolve the faults, as indicated in the following tables. In cases where there is more than one possible cause, they are listed from the most likely to the least likely cause. Actions are listed in the order that they should be performed; not all actions may need to be done. NOTE: If you have a red STATUS LED without a fault message, it probably indicates that the unit is locked out. Refer to Appendix C for tables containing Fault, Warning, and Status messages and their meanings. 9.3.2 Troubleshooting Using LEDs The following troubleshooting guide is from the perspective that all Fusion equip-

ment is installed, their cables are connected, and they are powered on; it is assumed that the system was operating normally before the problem to be diagnosed occurred. Always use AdminBrowser, if possible, to troubleshoot the system. The Fusion Main Hub and Expansion Hub LEDs are for backup troubleshooting. The RAU LEDs prob-

ably will not provide additional information for troubleshooting.

If any LEDs are red, get status using AdminBrowser to determine the exact cause and recommen-

dations. Table 9-1 Troubleshooting Main Hub Port LEDs During Normal Operation During Normal Operation Expansion Hub Not Connected Main Hub Port LEDs PORT State Red Action If the Expansion Hub was discon-

nected accidentally, re-connect the cables. The LEDs should change to Green/Red (then Green/Green, after 20 seconds, if the Main Hub band has been programmed). When the Expansion Hub is to be removed from service permanently, use AdminBrowsers Clear All Dis-

connect Status command to clear all disconnect states to no connect states. PORT Expansion Hub Connected Red 60 ppm) Use AdminBrowser to determine the exact cause of the Main Hubs faults.

nected; the Expansion Hub uplink cable disconnected. AdminBrowser clears all disconnects caused by installation as part of the clean-up process. After installation, power cycle the Main Hub or use AdminBrowsers Clear All Discon-

nect Status command. Changes the Main Hubs port LEDs to Off/Off. Lost communication with Expansion Hub; could be Expansion Hub problem or fiber cable problem. The Expansion Hub communication problems delay MH responses to AdminBrowser commands, resulting in command time-outs. You can discon-

nect the offending Expansion Hub ini-

tially to obtain status from the rest of the system, then connect the Expansion Hub and resolve the communication problem. Degraded performance or unit may be off-line.

Operation is subject to the following two conditions: (1) this device may not cause harm-

ful interference, and (2) this device must accept any interference received, including interference that may cause undesired operation. B.2 Human Exposure to RF The U.S. Federal Communications Commission (FCC) has developed guidelines for evaluation of human exposure to RF emissions. The guidelines incorporate limits for Maximum Permissible Exposure (MPE) for power density of transmitters operating at frequencies between 300 kHz and 100 GHz. Limits have been set for portable, mobile, and fixed equipment. LGC products fall in the category of fixed equipment;

products intended to be permanently secured and exposures are evaluated for dis-

tances greater than 20cm (7 7/8). Portable devices fall into exposures of less than 20cm, are SAR evaluations are used. Antenna gain is restricted to 1.5 W ERP (2.49 W EIRP) in order to satisfy RF expo-

sure compliance requirements. If higher than 1.5 W ERP, routine MPE evaluation is needed. The antennas should be installed to provide at least 20 cm from all persons to satisfy MPE requirements of FCC Part 2, 2.1091. Basic MPE evaluation is performed by taking the maximum power output of the equipment, the gain of the antenna to be used, and distance from the antenna, refer-

enced in FCC OET Bulletin 65 Evaluation Compliance with FCC Guidelines for Human Exposure to Radio Frequency for Electric Fields. LGC products transmit well below the FCC power density limits. FCC defines power output limits at 20cm distance for various frequency ranges:

Over 300 mHz to 1.5 GHz the limit is determined by frequency/1500 Above 1.5 GHz the limit is 1mW/cm2 The basic equation for determining power density is:

S = PG / 4R2 1. Manufacturers rated output power refers to Fusions downlink P1dB. The power per carrier tables take into account this power reduction for multiple carriers. D-620610-0-20 Rev B Help Hot Line (U.S. only): 1-800-530-9960 B-3 CONFIDENTIAL Where S is power density in mW/cm2 PG, the transmitted power from the antenna identified as EIRP (Equivalent Isotropi-

cally Radiated Power), is the product of power output of device and antenna gain, in mW. R is the distance of interest from the antenna. Typical Installation Example:

Assuming an antenna is placed on a 10 foot ceiling, for a person 6 feet tall, the dis-

tance from antenna to body is 4 feet (112 cm.). For a PCS 1900 or Cell 850 remote unit, the maximum power output, according to the power table in Section 6.3 Maximum Output Power per Carrier on page 6-4, is 16.5 dB. Assuming a 7 dBi antenna is used, PG in the equation is equal to 23.5 dB (224 mW) EIRP. Using S = PG/4R2 S = 224/(4x3.14) x (122)2 = 0.001 mW/cm2 Also, assuming a minimum distance of 20 cm according to FCC regulations S = 224/(4 x 3.14) x (20)2 = 0.04 mW/cm2 B-4 CONFIDENTIAL InterReach Fusion Installation, Operation, and Reference Manual D-620610-0-20 Rev B APPENDIX C Faults, Warnings, Status Tables This appendix contains the following sections:
