Mounting the Repeater Reference Manual2-4 RTI Confidential 550-1300-01 Rev C2.1.1 Wall MountingCustomer 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 wash-ers), 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.

Mounting the Repeater Reference Manual2-6 RTI Confidential 550-1300-01 Rev C2.1.2 Pole MountingNOTE: 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 rug-ged 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 ordi-narily 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 recom-mended. 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, tele-phone# (562)692-5911.

Connecting Primary Power to the Repeater Reference Manual3-2 RTI Confidential 550-1300-01 Rev C3.1 AC Power WiringThe following steps describe how to connect AC power to the repeater:NOTE: Before wiring the repeater, verify that all input power is OFF and all circuit breakers in the repeater are in the OFF position.Figure 3-1 Line Entry Module - AC Wiring1. Route AC power to the repeater 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. See Figure 3-1.2. Wire the repeater using #14 AWG or larger stranded PVC wire. Connect the neutral and hot leads to the Line Entry Module and the ground lead to the interior ground lug located on the inside of the cabinet. Connect the repeater to an AC power source using a dedicated 15 Amp fuse or circuit breaker.NOTE: Number 14 gauge wire complies with most local and national electrical codes because the Repeater Power Switch is also a magnetic circuit breaker which limits current to a maximum of 15 Amps. Consult your local or national electrical safety codes for the appropriate wire sizes.3. Close the AC circuit breaker to turn the repeater on.

Connecting Primary Power to the Repeater Reference Manual3-6 RTI Confidential 550-1300-01 Rev CThe 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 appro-priate 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 speci-fications are:115 Volts AC @ 10 Amps230 Volts AC @ 5 Amps3. 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 neces-sary 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 nor-mal conditions, the load should be approximately 9 - 15 Amps depending on the repeater model. Reference Table 3-1

Reference Manual Connecting Primary Power to the Repeater550-1300-01 Rev C RTI Confidential 3-93.4 GroundingConnecting input power to the repeater includes installing the standard electrical service grounds. However, you must also make sure that the repeater and any associated equip-ment 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 3-74. Ground all other cabinets, enclosures, antennas, and coaxial cables used for installa-tion, to reduce any damage from a lightning strike or power surge.Figure 3-6 Location of External Ground LugRT199105Exterior GroundAttachment PointCopper Ground(6 AWG min)

550-1300-01 Rev C RTI Confidential 4-14Installing Antennas4.0 Moisture Protection for Antenna ConnectionsNOTE: This should be done after the repeater has been fully configured, functionally set-up 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 sub-scriber antennas.

Reference Manual Installing Antennas550-1300-01 Rev C RTI Confidential 4-94.2 Antenna CablesA 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 antenna4.3 Lightning ProtectionRTI 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 min-imize the risk of damaging a repeater, and of losing cellular phone coverage, during light-ning 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 Reference Manual4-10 RTI Confidential 550-1300-01 Rev CFigure 4-8 shows a typical repeater installation, using coaxial lightning arrestors on the feeder lines. For safety and operational dependability, RTI also recommends attaching all antennas to the repeater site's single point ground.Figure 4-8 Lightning Arrestor, Grounding, and Repeater RF CablingTranscientSurge/LightningProtectionRepeater SiteEarth Ground(Minimum 6 AWGCopper Wire)RepeaterCabinetLightning Arresters(Customer supplied)To ServiceInterconnection(Power, Phone)RT204102

Reference Manual Installing Antennas550-1300-01 Rev C RTI Confidential 4-114.4 Back-Beam Antennas and Directional CouplersA 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•90/10These 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 IsolationMeasure 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.

Reference Manual Installing Antennas550-1300-01 Rev C RTI Confidential 4-13Figure 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 iso-lation measurement, should be the one from the signal generator, and the one to the spec-trum 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 fre-quency but not in the carrier itself.Figure 4-10 Antenna Isolation Measurement - Equipment ConfigurationNOTE: 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 isISO = PGEN - LC-GEN + LC-SA - PSATop JumperCablesBack-BeamAntennaMain-BeamAntennaFeederCablesLightning ArrestorsBottom JumperCablesSpectrumAnalyzerSignalGeneratorDonor AntennaTopJumperCableFeederCableBottomJumperCableLC-SART130109LC-GEN

Installing Antennas Reference Manual4-14 RTI Confidential 550-1300-01 Rev CWhere:Where:NOTE: A signal level of -88 dBm is stronger than a level of -90 dBm.In this example, the usable antenna isolation is 88 dB.ISO = Isolation in dB between the antennasPGEN = Output level of the signal generator (dBm)LC-GEN = Loss of the signal generator cable (dB)LC-SA = Loss of the spectrum analyzer cablePSA = Power indicated on the spectrum analyzer (dBm)This equation holds true for one donor antenna, and for one vertically-polarized sub-scriber antenna. For a dual-polarized antenna, the equation becomes:ISO = PGEN - LC-GEN + LC-SA - MAX(PSA(L), PSA(R))PSA(L) = Spectrum analyzer level measured on the left antenna port.PSA(R) = Spectrum analyzer level measured on the right antenna port.The stronger of the two readings represents the actual isolation available. For example:PGEN = 0 dBmLC-GEN = 1.0 dBLC-SA = 1.0 dBPSA(L) = -90 dBmPSA(R) = -88 dBmISO = 0 - MAX(-90 or -88) = 88 dB

Reference Manual Installing Antennas550-1300-01 Rev C RTI Confidential 4-154.6 Sweeping Antenna CablesRTI 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 nor-mal base station. At a minimum, record the following data, for each cable or cable assem-bly:•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 imped-ance.•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.

Reference Manual Configuring the Repeater550-1300-01 Rev C RTI Confidential 5-575.11.4 Pager Setting TabThe 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:1920-2where 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 soft-ware 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.

Click on the Pager Setting tab of the Remote Monitoring Properties screen.2. Enter the Pager Number.The Pager Number is the phone number the repeater will dial. This phone number must include the networking access number (example 9), 1 and the area code (if needed).Normally, several commas must follow the phone number. Each comma generates a delay of one second. Generally, a pager company requires about three seconds to pick up the line, and allows a maximum of five seconds before they drop the connection.Alarm Type Severity NumberNo Alarms 0Critical Alarm 1Major Alarm 2Critical + Major 3Minor Alarm 4Critical + Minor 5Major + Minor 6Critical + Major + Minor 7RT221108

Enter the number of times RepeaterNet should attempt to dial the pager number (Page Attempts). The repeater will page the number of times specified. Example: If attempts is set to one, the repeater will page once, if set to three, then three attempts will be made.NOTE: A value of zero (0) in this field disables paging.

550-1300-01 Rev C RTI Confidential 7-17Final Testing and Optimization7.0 Link Engineering Considerations7.0.1 Ensuring Adequate Isolation for a Repeater ApplicationCompare 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 Issues7.1.1 Worst-case Position for Active Search Window WidthThis 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.

Final Testing and Optimization Reference Manual7-2 RTI Confidential 550-1300-01 Rev C7.1.2 Worst-case Position for Neighbor Search Window WidthThis 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:Where: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. ∆(Chips) = D+R+S-N(Chips)∆(Chips) = Differential_Delay(Chips)D = Donor_Path_Length(Chips)R = Repeater_Delay(Chips)S = Subscriber_Path_Length(Chips)N = Neighbor_Path_Length(Chips)

Reference Manual Final Testing and Optimization550-1300-01 Rev C RTI Confidential 7-37.1.3 Channel Search Window Width for Reverse Link AccessThe 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 (round-trip 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-chan-nel 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 parame-ters (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 Applica-tion Engineering Group.

Final Testing and Optimization Reference Manual7-4 RTI Confidential 550-1300-01 Rev C7.1.4 Setting Radius of Traffic Channel Search WindowThe 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 acquisi-tion time of the reverse traffic channel. Due to the dynamic nature of the mobile propaga-tion 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.

Reference Manual Final Testing and Optimization550-1300-01 Rev C RTI Confidential 7-5The equation that calculates the TOA is similar (but not identical to) setting the neighbor search window:Where:After calculating the worst-case TOA, you can set the search window width accordingly.7.1.5 Updating an MTSO Data Base Using New Timing ParametersAfter 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 parame-ters. Do not perform this update until you are ready to activate the repeater. TOA (Chips)= D+R+S+N(Chips)TOA(Chips) = Differential_Delay(Chips)D = Donor_Path_Length(Chips)R = Repeater_Delay(Chips)S = Subscriber_Path_Length(Chips)N = Neighbor_Path_Length(Chips)

Final Testing and Optimization Reference Manual7-6 RTI Confidential 550-1300-01 Rev C7.2 Drive Testing Requirements7.2.1 Collecting DataTo 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 sitesFor 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 receiverThis equipment is available from a variety of sources, such as:•Qualcomm, Incorporated•Agilent•Grayson•LCC, Inc.•Berkeley VeritronicsAnalyzing 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.

550-1300-01 Rev C RTI Confidential 8-18CDMA Overview8.0 IntroductionIn 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 channelsThe 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: 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.Pilot Channel Power: 15 – 20%, depending on the requirements of the specific equipment manufacturer or service providerPaging Channel Power: 6%Sync Channel Power: 2%

CDMA Overview Reference Manual8-2 RTI Confidential 550-1300-01 Rev C8.1 Measuring the Donor BTS Signal StrengthIf 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 spec-trum 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 PowerIf 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 meth-ods: •Spectrum analyzer•Pilot Scanner (CDMA)Both methods use the same equipment configuration, as shown in Figure 8-1.Figure 8-1 Equipment Configuration for Measuring Donor BTS PowerSubscriber Antennas DonorAntennaDiversity MainREPEATERSpectrumAnalyzerMain Subscriber PortDiversitySubscriberPortDonorantennaportRT130104

Reference Manual CDMA Overview550-1300-01 Rev C RTI Confidential 8-3Measurement Using a Spectrum AnalyzerUse 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 PowerIf the donor BTS is active (carrying subscriber traffic), you cannot use a spectrum ana-lyzer 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 Scanner1. 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.
