Installation Requirements
7.1.1 Component Location Requirements
7.1.2 Cable and Connector Requirements
NOTE: Faulty cabling is the cause of a vast majority of problems. All CATV cable
should be tested to TIA-570-B specifications.
Fusion components are intended to be installed in indoor locations only.
If outdoor installation is desired, such as a parking garage, the Fusion components
must be installed in the appropriate environmental enclosures.
Fusion equipment operates over the following:
• CATV 75 Ohm cable with F connectors
• Single-mode fiber (SMF) or multi-mode (MMF) cable with SC/APC fiber connectors throughout the fiber network, including fiber distribution panels
These cables are widely-used, industry standards for the cable TV industry. The regulations and guidelines for Fusion cable installation are identical to those specified by
the TIA/EIA 568-B standard and the TIA/EIA/570-A standards.
LGC Wireless recommends solid copper center conductor, plenum-rated CATV cable
and connectors for conformity to building codes, standards, and to ensure stated performance of maximum distance and RF specifications.
CommScope 2065V cable or equivalent is required for RG-59.
CommScope 2279V cable or equivalent is required for RG-6.
CommScope 2293K cable may also be used for RG-11.
NOTE: Refer to Appendix A for more information related to 75 Ohm
CATV.
LGC Wireless recommends connectors with fixed centerpins to ensure proper seating
and to eliminate oxidation, which occurs with bare center conductors. Recommended
connectors are as follows:
CANARE Connectors
• FP-C4F for commScope 2065V cable
• FP-C55A for CommScope 2279V cable
• FP-C71A for CommScope 2293K cable

7.2.1 Installation Guidelines
Use the following guidelines when installing LGC Wireless equipment:
1.
Provide sufficient airflow and cooling to the equipment to prevent heat build-up
from exceeding the maximum ambient air temperature specification. Do not compromise the amount of airflow required for safe operation of the equipment.
2.
If you are removing the system, turn it off and remove the power cord first. There
are no user-serviceable parts inside the components.

CONFIDENTIAL
Safety Precautions
3.
The internal power supplies have internal fuses that are not user replaceable. Consider the worst-case power consumption shown on the product labels when provisioning the equipment’s AC power source and distribution.
4.
Verify that the Hub is grounded properly using the AC power cord third wire
ground.
NOTE: Be careful with the mechanical loading of the rack mounted hub.
Mount the equipment in the rack in such a way that a hazardous condition,
due to uneven mechanical loading, does not result,.
7.2.2 General Safety Precautions
The following precautions apply to LGC Wireless products:
• The units have no user-serviceable parts. Faulty or failed units are fully replaceable
through LGC Wireless. Please contact us at:
1-800-530-9960 (U.S. only)
+1-408-952-2400 (International)
• Although modeled after an Ethernet/LAN architecture and connectivity, the units
are not intended to connect to Ethernet data hubs, routers, cards, or other similar
data equipment.
• When you connect the fiber optic cable, take the same precaution as if installing
Ethernet network equipment. All optical fiber SC/APC connectors should be
cleaned according to the cable manufacturer’s instructions.
• When you connect a radiating antenna to an RAU, firmly hand-tighten the N connector – DO NOT over-tighten the connector.
WARNING: To reduce the risk of fire or electric shock, do not
expose this equipment to rain or moisture. The components are
intended for indoor use only. Do not install the RAU outdoors. Do not
connect an RAU to an antenna that is located outdoors where it could
be subject to lightning strikes, power crosses, or wind.
• The Expansion Hub and RAU units are designed for intra-building cabling only.
Outdoor routing of any cabling to these units shall not exceed 140 feet.
NOTE: Outdoor cables farther than 140 feet must be installed with proper

Connecting the Fiber Cables to the Main Hub
Considerations:
• Before connecting the fiber cables, confirm that their optical loss does not exceed
the 3 dB optical budget.
• If you are using fiber distribution panels, confirm that the total optical loss of fiber
cable, from the Main Hub through distribution panels and patch cords to the
Expansion Hub, does not exceed the optical budget.
• Make sure the fiber cable’s connectors are SC/APC (angle-polished). Using any
other connector type will result in degraded system performance and may damage

Fusion Installation Procedures
To clean the fiber ports:
You can clean the Hub’s fiber ports using canned compressed air or isopropyl alcohol
and foam tipped swabs.
Considerations:
• If using compressed air:
• The air must be free of dust, water, and oil.
• Hold the can level during use.
• If using isopropyl alcohol and foam tipped swabs:
• Use only 98% pure or more alcohol
Procedure using compressed air:
1.
Remove the port’s dust cap.
2.
Spray the compressed air away from the unit for a few seconds to clean out the
nozzle and then blow dust particles out of each fiber port.
Procedure using isopropyl alcohol:
1.
Remove the connector’s dust cap.
2.
Dip a 2.5mm lint-free, foam-tipped swab in isopropyl alcohol and slowly insert
the tip into the connector.
3.
Gently twist the swab to clean the port.
4.
Insert a dry swab into the port to dry it.
Additionally, you can use compressed air after the alcohol has completely evaporated.
To clean the fiber ends:
Be sure that the fiber cable’s SC/APC connectors are clean and free of dust and oils.
You need lint-free cloths, isopropyl alcohol, and compressed air
1.
Moisten a lint-free cloth with isopropyl alcohol.
2.
Gently wipe the fiber end with the moistened cloth.
3.
Using a dry lint-free cloth, gently wipe the fiber end.
4.
Spray the compressed air away from the connector for a few seconds to clean out
the nozzle and then use it to completely dry the connector.
To test the fiber cables:
Perform cable testing and record the results. Test results are required for the final
As-Built Document.
To connect the fiber cables:
The fiber cable is labeled with either 1 or 2, or is color-coded. In addition to these
labels, you should add a code that identifies which port on the Main Hub is being

Connecting the Fiber Cables to the Expansion Hub
Considerations:
• Before connecting the fiber cables, confirm that their optical loss does not exceed
3 dB optical budget. RL is less than -60dB.
• If fiber distribution panels are used, confirm that the total optical loss of fiber
cable, from the Main Hub through distribution panels and patch cords to the
Expansion Hub, does not exceed the optical budget.
• Make sure the fiber cable’s connectors are SC/APC (angle-polished).Using any
other connector type will result in degraded system performance and may damage
the equipment. (You can use an SC/APC pigtail if the fiber cable’s connectors are
not SC/APC, refer to “Fusion Splicing of Fiber and Pigtail” on page 7-37, or
replace the connectors.)
NOTE: Observe all Fiber Port Safety Precautions listed in Section 7.2.3 on page 7-5.
To connect the fiber cables:
The fiber cable is labeled with either 1 or 2, or is color-coded. For proper connection

7.4.3 Installing RAUs
CAUTION: Install RAUs in indoor locations only. Do not con-
nect an antenna that is installed in an outdoor location to an RAU.
For outdoor installations, a protective enclosure is required.
Installing RAUs
Mount all RAUs in the locations marked on the floor plans.
Considerations:
• 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 7-27 for recommended 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
• 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.

D-620610-0-20 Rev A
Installing Passive Antennas
Refer to the manufacturer’s installation instructions to install passive antennas.
Location
Passive antennas are usually installed below the ceiling. If they are installed above
the ceiling, you must consider the additional loss due to the ceiling material when
estimating the antenna coverage area.
800/850 MHz Isolation Requirements
When deploying any RF system, give special attention to preventing receiver blocking 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

these situations is to provide sufficient isolation by physically separating the interfering 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 7-9 depicts these nearly contiguous bands, with arrows indicating the interfering downlink and receiving uplink
bands.
Figure 7-9
800/850 MHz Spectrum
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 downlink-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 7-10
Guideline for Unison RAU Antenna Placement
800 MHz iDEN Downlink and 850 MHz Cellular Uplink
A 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 downlink intermodulation products may fall within the 850 Cellular uplink band. In addition, 800 iDEN downlink signals near the lower edge of the band at 851 MHz may

Fusion Installation Procedures
cause the 850 Cellular uplink automatic level control (ALC) circuitry in the RAU to
engage and thereby reduce uplink gain.
To prevent either of these conditions, use the following guidelines:
• In-band 800 iDEN intermodulation products < -90dBm
• Lower frequency 800 iDEN signals < –30dBm for Fusion
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.
To prevent either of these conditions, use the following guidelines:
• In-band 850 Cellular intermodulation products < -90dBm
• Upper frequency 850 Cellular signals < –30dBm for Fusion
Given a typical DAS configuration (6 CDMA carriers for Fusion, omni-directional
antennas, line of sight), these guidelines translate to an antenna spacing (d2) of 8-14
meters.
Spacing between RAUs FSN-8519-1 and FSN-809019-1 should be in a range of from
8 to 14 meters.
Connecting the Antenna to the RAU
Connect a passive multi-band antenna to the N connector on the RAU using coaxial
cable with the least amount of loss possible.
CAUTION: Firmly hand-tighten the N connector – DO NOT
over-tighten the connector.
Connecting the CATV Cable
Considerations:
• Verify that the cable has been tested and the test results are recorded. This information is required for the As-Built Document.
• Verify that only captive centerpin 75 Ohm Type-F connectors are used on the solid
copper center conductor CATV 75 Ohm cable.
• Verify that the CATV cable is labeled with:
