Installation Overview
RTI repeaters are designed for indoor or outdoor installation, and can be mounted on
either a wall or a pole. The unit's compact cabinet simplifies installation, and its aesthetically-acceptable design means that it conforms to zoning standards in many locations.
NOTE: Two people are recommended for mounting the repeater.
NOTE: Only qualified service or technical personnel should install the repeater.
Figure 2-1 shows a typical repeater installation with a Back-Up Power System (BUPS).
NOTE: RTI Repeaters are not intended for mobile operation and should be placed in a
fixed location.

Reference Manual
Wall Mounting
Customer supplied hardware for wall-mounting a repeater includes the following:
• Four(4) lag (hexagonal-head) bolts
• Four(4) flat washers
• Four(4) split-lock washers
To mount the repeater on a wall:
1. Separate the rear mounting bracket from the repeater by removing the security bolts
and washers.
To do this, use either a ratchet or a 1/4" hex driver, and the 7/32" pin-in-socket driver
that is provided in the accessory kit.
2. Using the mounting hardware (hex-head lag bolts, split-lock washers, and flat washers), secure the bracket to a wall.
3. To set the repeater into the bracket, align the top of the repeater cabinet just above the
top of the mounting bracket so that the mounting bracket will fit inside the left and
right walls of the repeater cabinet.
4. Slide the repeater cabinet downward so that the guide bolt (on the repeater cabinet)
slips into the guide slot (on the mounting bracket), as shown in Figure 2-3.
5. Replace the security bolts and washers that were removed in Step 1.

Reference Manual
Pole Mounting
NOTE: Two people are recommended for pole-mounting the repeater.
RTI offers optional pole-mounting equipment that you can order with the repeater.
Pole installation requires the following materials:
• Pole mounting kit (available from RTI). See Table 2-1.
• Banding kit (purchased separately; available from McMaster-Carr) for mounting
the repeater on a concrete or metal pole. See Table 2-1.
• Class A - Pole Line Hardware for bolting the Pole Mounting Bracket to a wood
pole.
• Class A - Pole Line Hardware is a telephone term. It specifies bolts and screws
that have a heavy electro-galvanized plating so they do not rust. This type of rugged hardware typically is available from telephone equipment distributors such
as Graybar Electric, ALLTEL Supply, Spring-North Supply, PowerTel Supply, and
so on. The same type of hardware is also available from antenna suppliers and
from tower erector companies.
The Pole Mounting Channel is designed so that the repeater is squarely mounted on the
pole and does not wobble.
When mounting the repeater onto a concrete or metal pole, use the Banding Kit. You ordinarily would not drill a mounting hole through the center of a concrete pole. Similarly,
because metal poles might have cables running up the center, drilling is not recommended. In both cases, banding is preferred over drilling.
However, wood telephone-type poles are easier to drill, so you can use lag screws or
through-pole bolts to fasten the pole-mounting channel.
Table 2-1 describes the Pole Mounting and Banding Kits. Because the Banding Kits
includes 100 feet of band, you do not need to purchase a separate kit with every repeater.
The banding kit is available from McMaster Carr Supply Co, Los Angeles, CA USA, telephone# (562)692-5911.

Connecting Primary Power to the Repeater
Reference Manual
The following steps describe how to power a BUPS and connect it to a repeater:
NOTE: Before wiring the repeater, verify that all input power is OFF and all circuit
breakers in the repeater and BUPS are in the OFF position.
1. Route AC power to the BUPS using 1/2" liquid tight flexible conduit, and the appropriate liquid tight conduit fittings. Access holes are located at the bottom of the
repeater for convenience. For indoor installations, normal 1/2" metal conduit may be
used.
2. Wire the BUPS using #10 AWG or larger stranded PVC wire. Connect the neutral, hot
and ground leads to the rectifier front panel. Figure 3-4 shows the front panel of the
BUPS Charger-Rectifier. Connect the BUPS to an AC power source using a dedicated
15 Amp fuse or circuit breaker. Typical BUPS-25/80 input voltage and current specifications are:
115 Volts AC @ 10 Amps
230 Volts AC @ 5 Amps
3. Install the two 12-volt Gel Cell batteries.
4. Use the wires provided with the BUPS to connect the batteries to the rectifier.
5. Verify the battery voltage at the BUPS Rectifier terminal block, using a multi-meter.
The multi-meter should read approximately 25 to 27 Volts.
6. Wire the BUPS to the repeater as shown Figure 3-5. The RTI BUPS-25/80 includes the
1/2" Liquidtight flexible steel conduit, the power and alarm wiring, and the necessary Liquidtight conduit fittings to connect the BUPS to the repeater.
7. Close the BUPS AC Input circuit breaker.
8. Close the BUPS Charger circuit breaker.
9. Close the Battery circuit breaker.
10. Verify the voltage using the BUPS Test Terminals. The multi-meter should read
approximately 27 Volts.
11. Close the repeater DC circuit breaker.
12. Observe the Repeater load in Amps using the BUPS Load Test Terminals. Under normal conditions, the load should be approximately 9 - 15 Amps depending on the
repeater model. Reference Table 3-1

Connecting Primary Power to the Repeater
Grounding
Connecting input power to the repeater includes installing the standard electrical service
grounds. However, you must also make sure that the repeater and any associated equipment is properly grounded to a water pipe or earth ground. For more information about
grounding repeaters, consult the RTI Application Note titled Installation Standards for
Ground Requirements, Document Number 650-0002-01, Rev. 2.
The repeater cabinet includes one external ground lug as shown in Figure 3-6.
1. Connect number 6 AWG minimum solid copper wire to the repeater ground lug.
2. Carefully dress the wire along cabinet, and the mounting surface, to the Repeater
Grounding System or the Ground Rod.
NOTE: When dressing the ground wire, and forming it around corners, avoid making
sharp bends in the wire. Use a generous radius for each wire bend.
3. Connect the ground wire to a suitable earth ground - for example, to a copper
ground rod, copper pipe, grounded steel building frame, or similar ground point. see Figure 3-7
4. Ground all other cabinets, enclosures, antennas, and coaxial cables used for installation, to reduce any damage from a lightning strike or power surge.

Moisture Protection for Antenna Connections
NOTE: This should be done after the repeater has been fully configured, functionally setup and further work is not required.
The bottom of the repeater cabinet has N-type (7/16" DIN is optional) connections for
donor and subscriber antennas, as shown in Figure 4-1. RTI recommends that before
installing the repeater and connecting it to the antennas, you apply a tar-like Vapor Wrap,
to seal these antenna connections against rain or other water sources (See Figure 4-2).
1. Wrap the threads of the N-type antenna connectors, with electrical tape. This protects
the connector threads from the sticky Vapor Wrap substance.
2. Thoroughly coat the outside of the electrical tape with the Vapor Wrap putty.
3. Wrap another layer of electrical tape over the Vapor Wrap to seal the Vapor Wrap
into place.
After you complete this procedure for all N-type antenna connectors, moisture should
not adversely affect the connections between the repeater cabinet, and the donor and subscriber antennas.

Antenna Configurations
RTI repeaters can use any one of following antenna configurations:
• Donor antenna, and one dual polarized subscriber antenna (see Figure 4-3)
• Donor antenna, and two vertically polarized subscriber antennas (see Figure 4-4)
• Donor antenna, and two dual polarized subscriber antennas-back beam configuration (see Figure 4-5)
• Donor antenna, and one vertically polarized subscriber antenna (see Figure 4-6)
• Donor antenna, and two dual polarized subscriber antennas-dual direction configuration (see figure Figure 4-7)
NOTE: When included in a CDMA network, an RTI repeater can use a back-beam
antenna, to transmit energy from the repeater, back towards the donor base station. A
back-beam antenna increases the allowable distance between the donor BTS and the
repeater site.

Installing Antennas
Antenna Cables
A repeater uses the same type of RF cabling as a base station does. Usually, the top and
bottom jumper cables are made from flexible, 1/2" air dielectric coaxial cable, and the
feeder lines are made from 7/8" to 1-5/8" foam dielectric coaxial cable.
Diversity repeater configurations (see Figure 4-3, Figure 4-4, and Figure 4-5) require
three(3) RF lines:
• One for the donor antenna
• One for the main subscriber antenna
• One for the diversity subscriber antenna
4.3
Lightning Protection
RTI strongly recommends installing lightning arrestors on all feeder cables to the
repeater. A direct lightning strike can damage any electronic equipment. Damage
resulting from a lightning strike is not covered under the RTI manufacturer's warranty,
whether or not you use lightning arrestors. However, using lightning arrestors can minimize the risk of damaging a repeater, and of losing cellular phone coverage, during lightning storms.
Use lightning arrestors that attach directly to the large-diameter feeder cables, and not to
the repeater itself. Do not use screw-on lightning arrestors, because they attach to the
repeater's antenna terminals. Shunt the lightning to the ground, as far away from the
repeater as possible.
For additional lightning protection of the power and telecommunication lines, please
contact RTI.

Installing Antennas
Back-Beam Antennas and Directional Couplers
A back-beam antenna transmits a portion of the repeater's power back toward the donor
base station (BTS). This technique is helpful on long rural routes, where two repeaters are
cascaded. In suburban or rural areas, this type of antenna can provide additional signal
capability, in the area between the donor BTS and the repeater site.
As shown in Figure 4-5, power from the repeater is applied to a directional coupler (or
power divider), which divides the power proportionately to both the main-beam and
back-beam antennas. These couplers are available in several power division ratios:
• 50/50
• 60/40
• 75/25
• 80/20
• 90/10
These ratios represent the percentage of total power that the repeater channels either to
the direct port (the higher number) or the coupled port (the lower number). For example,
if the repeater uses a 75/25 coupler, the repeater sends 75% of its power to the main-beam
subscriber antenna, and the remaining 25% to the back-beam antenna.
4.5
Measuring Antenna Isolation
Measure the actual isolation between the antennas, to ensure that the donor (base station)
antenna is sufficiently isolated from the subscriber (mobile) antenna. See Figure 4-9 and
Figure 4-10.
WARNING: This is a crucial step in all repeater installations.
If the isolation is not sufficient, the repeater might oscillate, or it might operate with less
gain (signal amplification). In the first case, the repeater can introduce spurious emissions
into the network. The second case, reduces the range of the repeater's coverage area.

Measuring antenna isolation requires a signal generator and a spectrum analyzer. The
generator transmits a signal from the donor antenna, and the spectrum analyzer measures the same signal as the subscriber antenna receives it. Figure 4-9 shows the equipment set-up for each antenna configuration.

Installing Antennas
Figure 4-9 shows four simplified setups. They show only the overall configuration for
measuring antenna isolation. Isolation must take into account all cables that will be
attached when the repeater is in operation. You must measure isolation with all jumpers
and feeder lines in place. The only other cables present, that are not part of the actual isolation measurement, should be the one from the signal generator, and the one to the spectrum analyzer. Figure 4-10 shows all cables and equipment in place for measuring actual
antenna isolation. Isolation should be measured as close as possible to the carrier frequency but not in the carrier itself.

NOTE: If the repeater uses a back-beam antenna, you must measure antenna isolation
from both ports of both antennas (four measurements). If the repeater uses only one
antenna, only two isolation measurements are needed: one from the left port, and one
from the right port, of the subscriber antenna.
In all cases, measure antenna isolation with all cables, connectors, and lightning arrestors
in place. Record all measurements for future reference.
The equation for antenna isolation is

Installing Antennas
Sweeping Antenna Cables
RTI recommends sweeping all RF cables for the repeater, using a network analyzer or a
time-domain reflectometer. This procedure is similar to the sweeping required for a normal base station. At a minimum, record the following data, for each cable or cable assembly:
• Return Loss (dB): the ratio of power transmitted to, versus reflected from, the
cable.
• Voltage Standing Wave Ratio (VSWR): a factor in measuring the cable's impedance.
• Insertion Loss (dB): the ratio of power delivered with the cable, versus without
the cable.
• Distance (in feet or meters) from one end of the cable, to a detected fault.
CAUTION: If the sweep finds any faults, correct them before placing the repeater into
service.

RepeaterNet Craft Software
The RepeaterNet Craft Software provides configuration management and alarm monitoring capabilities for individual repeaters from RTI. It also dynamically manages repeater
maintenance sessions in real time through one of the following connections:
• Direct Connection - A laptop computer with a direct connection to the repeaters a technician can visit repeater sites and connect to a repeater directly, using the
serial port on the laptop.
• Remote Connection (optional) - A laptop or desktop computer with a modem
connection to the repeater - a technician can use the modem to connect to a
repeater, without visiting the physical repeater site.
The Craft software can operate under either Windows 95, 98, ME, Windows NT4, or Windows 2000. The Craft user interface varies, depending on the model of repeater that the
software is configured for monitoring.

Status Reporting
After configuring the repeater, you can use the subsystem Status screens to monitor and
control repeater system functions. For example, when a repeater alarm triggers, the
appropriate subsystem icon for the type of alarm changes appearance, and starts blinking.
1. Click on the subsystem icon for the type of alarm that triggered.
The appropriate status screen opens. The icon stops blinking and the audible alarm
stops. This acknowledges that you are aware of the alarm condition. However, the
icon remains the color of the alarm condition.
2. Fix the problem that triggered the alarm.
After you clear the alarm condition the display of the icon reverts to normal.
The display of the Forward PA and Reverse PA icons indicate the operational status of the
Power Amplifiers. If a PA is Off, a circle with a slash is displayed over the associated icon.

When an alarm is triggered, the icon color of the affected subsystem changes, from green
(normal), to the color of the alarm definition, and the icon blinks.
RepeaterNet also offers two optional alarm features:
The Color Independent Icons feature is provided for operators who are unable to distinguish color.
If an individual subsystem triggers more than one alarm, the Main Control Screen reports
the higher-severity alarm, in both the color and color-independent icons.
For example, if both a major and a minor Reverse PA alarm trigger, a yellow subsystem
icon is reported. If you clear the major alarm while the minor alarm remains active, a blue
subsystem icon is reported.
When a subsystem alarm triggers, click the icon (to open the status screen). This action
terminates the icon blinking feature, and silences the audible alarm. However, icon color
continues to report, and a color-independent icon (if applicable) continues to display
until you clear the condition that triggered the alarm.

5.11.4 Pager Setting Tab
The Pager Setting tab allows the Repeater to dial a pager when an alarm occurs. It also
assigns a specified minimum severity level to the alarm. Table 5-3 describes the Alarm
Severity settings.
NOTE: Use the most basic service for the pager.
RepeaterNet generates a page if the summary alarm severity is greater than or equal to
the selected Minimum Severity setting. The page format consists of the repeater number,
followed by the severity level. For example:
1920-2
where 1920 is the repeater number and 2 is the severity level of the alarm.
If RepeaterNet detects a change in the current alarm severity, it does the following:
• If you set the Minimum Severity to Major, the RepeaterNet software generates a
page with a severity of 2.
• If the RepeaterNet software detects a Critical alarm, it generates a new page with
a severity of 3.
• If you clear the Major alarm, but the Critical alarm remains, the RepeaterNet software generates a new page with a severity level of 1, indicating that the Critical
alarm remains.
• If you then clear the Critical alarm, the RepeaterNet software generates a page
with a severity of 0.
• If the RepeaterNet software detects a Minor or Event alarm, it does not generate a
page.
NOTE: Repeater pager function dials a specified number. When the remote connection
answers it goes off hook. The repeater outputs the alarm and disconnects. It is a one-way
communication.

Overview
This chapter describes how to connect external alarms and relays.
• Use the connector labeled UPS to wire alarms from the Back-Up Power Supply
(BUPS) to the repeater.
• Use the connector labeled IN/OUT for digital inputs to custom external alarms,
or for digital outputs to remotely-controlled devices at the repeater site.
• The connector labeled USER RELAY provides two independently-controlled dry
contact relays, each with standard 1C contact sets. RepeaterNet software can use
these relays to control devices at the repeater site.
• The connector labeled ALARM RELAY provides three independent relays, each
with contact sets in standard 1C form (SPDT). Each relay is driven by specific
summary alarms that the repeater generates. For example, one relay might activate whenever the repeater generates a critical alarm. Similarly, a second relay
might activate whenever the repeater generates a major alarm, and a third might
activate on a minor alarm
Table 6-1 lists all of the input and output connections, pin numbers, and functions, for all
repeater's external alarm connectors.
NOTE: The ground reference for IN/OUT and BUPS inputs and/or outputs is the chassis ground terminal.

You can use the alarm control relay contacts to activate external alarms or other equipment in the event of a repeater alarm.
Whenever the repeater generates an alarm, it also generates a summary alarm for that
severity. For example, if the repeater generates a critical alarm, it also generates a critical
summary alarm. The repeater generates similar summary alarms for major and minor
alarms.
Each summary alarm is connected to a relay. Figure 6-9 shows the basic internal circuit.
When the repeater generates an alarm, the transistor saturates and energizes the relay as

Link Engineering Considerations
7.0.1
Ensuring Adequate Isolation for a Repeater Application
Compare the maximum forward and reverse gain settings, to the available isolation.
• If the available isolation is at least 15 dB higher than the maximum gain setting, then
the repeater will operate with good stability.
• If the isolation is less than 15 dB higher than the maximum gain setting, then some
oscillation might result.
For CDMA systems, pre-oscillation begins at about 15 dB margin over gain, and becomes
very problematic at about 10 dB margin-over-gain. Therefore, you should strictly follow
the 15 dB margin-over-gain rule.
7.1
System Timing Issues
7.1.1
Worst-case Position for Active Search Window Width
This process estimates the required width setting for the active search window, to ensure
that the repeater properly covers a transition zone (between the base station and the
repeater).
The typical value required for SRCH_WIN_A=8. This value is more than sufficient for
most applications, where the repeater is less than three miles from the donor site, and the
repeater radius is two miles or less.
For additional information regarding system timing issues, call RTI.

7.1.2
Reference Manual
Worst-case Position for Neighbor Search Window Width
This process estimates the required width setting for the neighbor search window, to
ensure that the repeater properly covers a soft hand-off zone (between the base station
and the repeater).
The worst-case position is wherever the greatest differential delay exists, between the cell
that the mobile uses for timing and a hand-off candidate cell.
NOTE: This relationship is symmetrical and reciprocal for neighboring cells, if those
cells are candidates for the donor sector. That is, the neighbor cells also need wider search
windows.
Wider search windows can search the TOA (Time Of Arrival) of the specific pilot that is
associated with the donor sector (the pilot is accessible via the repeater).
The following equation calculates the differential delay:
∆(Chips)
= D+R+S-N(Chips)
Where:
∆(Chips)
= Differential_Delay(Chips)
= Donor_Path_Length(Chips)
= Repeater_Delay(Chips)
= Subscriber_Path_Length(Chips)
= Neighbor_Path_Length(Chips)
The typical process is:
1. Determine the place where the differential delay is greatest and where a mobile is
likely to be operating.
2. Calculate the differential delay.
This worst-case differential delay determines the SRCH_WIN_N parameter setting.
The typical value required for SRCH_WIN_N (for repeater operation in the transition
zone) is about ± 40 chips. This corresponds to SRCH_WIN_N = 9. This value is more than
sufficient for most applications where the repeater is less than three miles from the donor
site and the repeater radius is two miles or less.

Final Testing and Optimization
Channel Search Window Width for Reverse Link Access
The mobile station searches the forward link TOA probability space for new pilot offsets.
A similar search process occurs at the base station.
The base station modem chip (CSM) also contains a searcher. Both the access channel and
the traffic channel use this searcher to determine the TOA of the mobile's energy. Because
the access channel does not know how far an originating mobile is from the base station,
it must search the entire TOA probability space associated with the cell's maximum
radius.
For example, if the cell has a maximum radius of 20 chips, then the searcher must search
the range of relative TOA, from near zero chip delay (for very close mobiles), to delays as
great as 40 chips.
NOTE: The round trip delay is the important variable, because the mobile is "phase
locked" to the PN sequence of the down-link (forward link) path. Also, the TOA (roundtrip delay) of the base station is twice the one-way delay.
The cell radius plays a central role in determining the required width for the access-channel search window. Most CDMA network manufacturers derive all of the required search
window parameters from a simple parameter, called Cell_Radius or something similar.
Usually, if you set this parameter to the maximum cell radius, the Method Of Repeater
Engineering (M.O.R.E.) automatically calculates and updates all corresponding parameters (such as preamble size, PROBE_RAN_N, and so on).
NOTE: You must set this parameter properly. An incorrect setting can limit the range of
access to the base station via the repeater.
The setting for this parameter is simply the sum of the donor link radius, the repeater
delay in miles, and the maximum repeater coverage range as shown in the following
equation:
Cell_Radius(miles) =
Donor_Path_Length(miles)+[Repeater_Delay(µs)]*0.186+Repeater_Radius(miles)
If the equipment manufacturer does not provide a Cell Radius type parameter, or if you
need more information on this subject, please contact the Repeater Technologies Application Engineering Group.

Setting Radius of Traffic Channel Search Window
The new base station must acquire the reverse traffic channel during a soft hand-off
attempt. The search process is similar to the one that the access channel performs during
initial system access.
The Primary Base Station (initial base station) receives the Pilot PN Phase information in
the Pilot Strength Measurement Message. You can use this information to estimate the
Time of Arrival (TOA) at the new base station. This can significantly reduce the acquisition time of the reverse traffic channel. Due to the dynamic nature of the mobile propagation environment, and the delay associated with hand-off processing, the search window
must be wider than a single-point Time of Arrival (TOA) set. Typically, the reverse traffic
channel search window centers around the estimated TOA, and its width depends on
two factors:
• The accuracy of the TOA estimate.
• The maximum expected variation of the TOA during hand-off processing.
If the CDMA equipment manufacturer uses the Pilot PN Phase to estimate the TOA at the
neighbor base station, then the search window width needs to be only a few tens-of-chips
wide (± 20 chips). This is typically the case; however, some manufacturers might not use
the Pilot PN Phase data to estimate the TOA.
If the TOA estimate is not available for the neighboring base station, then you must run a
complete search of all possible Times of Arrival, just as you do during the access channel
search process. In this case, the search process takes longer, and therefore the hand-off is
slower. The required width of he search window, used in this process, depends on the
TOA of the mobile's energy at the new base station.

The equation that calculates the TOA is similar (but not identical to) setting the neighbor
search window:
TOA
(Chips)
= D+R+S+N(Chips)
Where:
TOA(Chips)
Differential_Delay(Chips)
Donor_Path_Length(Chips)
Repeater_Delay(Chips)
Subscriber_Path_Length(Chips)
Neighbor_Path_Length(Chips)
After calculating the worst-case TOA, you can set the search window width accordingly.

Updating an MTSO Data Base Using New Timing Parameters
After you determine all of the parameters, you can update both the Mobile Telephone
Switching Office (MTSO) data base, and the repeater data base, using the proper parameters. Do not perform this update until you are ready to activate the repeater.

Drive Testing Requirements
7.2.1 Collecting Data
To ensure proper repeater operation, drive test all of the following areas:
• Repeater Coverage area
• Transition zone between the donor base station coverage area and the repeater
coverage area
• Soft hand-off zones between the repeater and adjacent cell sites
For CDMA networks, RTI recommends that you accumulate data for both the forward
and reverse link, at the same time. Usually, this requires invoking "call trace," or some
similar function within the switch. Once invoked, the switch logs the test call by time
stamp. You can later correlate this to the forward link data.
This method helps you to more-accurately analyze the link balance and identify areas of
high RFER and/or high Mobile_TX parameters.
7.2.2 Collection Equipment
• The minimum equipment required for drive testing is:
• CDMA phone
• Serial data cable
• Laptop or notebook computer, running collection software
• GPS receiver
This equipment is available from a variety of sources, such as:
• Qualcomm, Incorporated
• Agilent
• Grayson
• LCC, Inc.
• Berkeley Veritronics
Analyzing the drive test results might require a change in network timing parameters,
and/or adjustment of the repeater subscriber antenna. That is, you must optimize
repeater, using the same methods as you use for a base station.

CDMA Overview
8.0
Introduction
In a CDMA (IS95) network, the dynamic RF power output of a Base Transceiver Station
(BTS) depends on the number of subscribers assigned to the BTS.
The IS-95 specification, for CDMA networks, describes four different channel types, all
contained within the forward channel:
• One pilot channel (measures power and performs initial synchronization)
• One sync channel (passes parameters during initial synchronization)
• 0 to 6 paging channels (passes parameters during operation)
• 0 to 62 traffic channels
The total number of channels cannot exceed 64.
Usually, a portion of the base station’s total power is assigned to the pilot channel, the
paging channel, and the sync channel. The traffic channels use the remaining power. For
example, within an IS-95 network, the power allocations usually adhere to the following
convention:
Pilot Channel Power:
15 – 20%, depending on the requirements of the specific
equipment manufacturer or service provider
Paging Channel Power:
6%
Sync Channel Power:
2%
The remaining 72-77% of the BTS power is available for communications traffic channels.
For each repeater installed into a CDMA network, you must determine the received
power level from the donor BTS, so that you can accurately set the repeater gain. If you
do not know the received power level, or if you use an inaccurate value, then the repeater
might become over driven, and it might enter into an alarm condition.

Measuring the Donor BTS Signal Strength
If the donor BTS is idle (not carrying any subscriber traffic), you can assume that the
repeater is radiating only pilot, paging, and sync power. If this is the case, connect a spectrum analyzer to the bottom jumper cable of the repeater’s donor antenna, and measure
the BTS power. Either use a spectrum analyzer that is equipped with a CDMA module, or
correct for the resolution bandwidth of the spectrum analyzer.
For example, a CDMA Personality Module is available for Agilent spectrum analyzers to
measure CDMA power within a 1.25 MHz band. For spectrum analyzers that do not have
such a module, however, the closest measurement bandwidth is 1.0 MHz, and you must
correct the measurement for bandwidth.
8.1.1
Measuring Donor BTS Idle Power
If the donor BTS is idle (no subscribers), then the only power that the BTS transmits is
pilot, paging, and sync. If this is the case, you can use either of two measurement methods:
• Spectrum analyzer
• Pilot Scanner (CDMA)
Both methods use the same equipment configuration, as shown in Figure 8-1.

CDMA Overview
Measurement Using a Spectrum Analyzer
Use the following procedure with a spectrum analyzer, to measure power from the Donor
BTS to the repeater.
1. Connect the spectrum analyzer to the output end of the bottom jumper cable on the
repeater donor antenna, as shown in Figure 8-1.
2. Ensure that the donor BTS is idle (no subscribers), and that only the pilot, paging and
sync channels are active.
NOTE: If the spectrum analyzer does not have a CDMA measurement module, skip to
step 4.
3. If the spectrum analyzer has a CDMA measurement module or capability, configure
the analyzer to measure the CDMA signal. Then record the signal strength, and skip
to step 5.
4. If the spectrum analyzer does not have a CDMA measurement module, proceed as
follows:
a. Configure the spectrum analyzer for a resolution bandwidth of 1.0 MHz, and for a
video resolution of 30 kHz.
b. Set Video averaging to ON.
c. Note and record the signal strength.
d. To correct the reading for a 1.25 MHz bandwidth, add 0.9 dB to the reading. For
example, if the spectrum analyzer indicates –55 dBm, the corrected reading is
-54.1 dBm (-54 dBm, for all practical purposes).
5. Move the antenna for maximum signal strength.
8.1.2
Measuring donor BTS Loaded Power
If the donor BTS is active (carrying subscriber traffic), you cannot use a spectrum analyzer to obtain an accurate measurement of the donor BTS signal strength. In this case,
you must use a Pilot Scanner and measure Pilot power directly.
Measurement Using a Pilot Scanner
1. Configure equipment as shown in Figure 5-1, but substitute a pilot scanner for the
spectrum analyzer.
2. Configure the pilot scanner to measure ONLY the pilot channel of the donor BTS.
3. Move the antenna for maximum signal strength.
