Appendix O: RFS System Test (Cable Sweeps)

Introduction

Before installing the Base Station at a site, the RFS and the associated cables must be tested, and

the results of the tests documented. This procedure applies to the full RFS sub-assembly and

associated cables: data/power cable, RF cables, and the RFS unit. All results are recorded in the

RFS System Test Form P/N 40-00093-00.

Procedures – Combo & Split Chassis Base Stations

RFS Data/Power Cable (Combo and Split BTS Configurations Only)

This test will check the integrity of the data/power cable. The cable being tested consists of six

twisted pairs of conductors. The conductors will be tested for continuity, opens, and shorts. Male

connectors are on both ends of the cable. Each connector is wired the same. You will need to

check all cables – the main cable from the RFS to the data/power cable surge protector, and the

jumper cable from the data/power cable surge protector to the BTS. The pin layout is shown in

Figure O1, looking at the connector face. Table O1 provides the pin layout details.

Perform the continuity test with both the Volt Ohm Meter (VOM) and the power/data cable

tester. If the power/data cable tester is not available, perform the continuity test with the VOM.

Required Equipment

?? VOM – Continuity tester

?? Jumper for shorting pins

?? RFS power/data cable tester

Continuity Test With VOM

Step 1. On one end of the cable, short a pair of conductors using a shorting device.

Step 2. Using a VOM/Digital Volt Meter (DVM) set to ohms, verify a short is present on the

pair at the other end.

Step 3. Leaving one probe on one of the paired pins, contact all of the other pins with the other

probe, ensuring an open connection.

Step 4. Check all 6 pairs of wires in the same manner.

Step 5. Verify continuity from the connector case to the drain wire (pin D) on each end of the

cable and between each connector case.

Step 6. Verify an open circuit from the connector case to each individual wire, except to the

drain wire.

A 1K ohms G 6.2K ohms

B 2K ohms H 8.2K ohms

E 3.3K ohms L 10K ohms

F 5.1K ohms M 12K ohms

Step 3. Using a VOM/DVM set to ohms, check resistance between the pairs on the other end

of the cable. Resistance should be the sum of the resistance of the two pairs, +/– 10

percent. Refer to Table O3.

Table O3: Resistance of Two Pairs

A & B 3K ohms G & H 14.4K ohms

E & F 8.4K ohms L & M 22K ohms

Step 4. Remove the power/data cable tester from the power/data cable.

Sweep Test of RF Cables & RFS

Sweep testing of the RF cables and the RFS is performed in three separate steps.

?? Sweep of the cables

?? Sweep of the RFS

?? Sweep of the cables and the RFS together

All results will be entered in the RFS System Test Form, P/N 40-00093-00. The total of the

insertion loss for the cables and the RFS will be equal to the insertion loss of both parts swept

together.

The following procedures are for the Agilent E4402B Spectrum Analyzer. If alternative

equipment is used, refer to the manufacturer’s calibration procedures. The key point is to make

accurate microwave frequency power measurements.

Step 1. Turn the Signal Generator and Spectrum Analyzer on. Allow the equipment to warm

up for 15 minutes for the output to stabilize.

Step 2. Set the Signal Generator frequency to the desired test frequency (Table O4) of the

RFS under test.

Step 3. Set the Signal Generator output amplitude to 0 dBm.

Step 4. Set the center frequency of the Spectrum Analyzer to the center frequency of the RFS

under test.

Step 5. Set the Spectrum Analyzer to Span = 5 MHz and Resolution Bandwidth = 100 kHz.

Step 6. Take a marker measurement on the Spectrum Analyzer by using the ‘marker to peak’

or the ‘peak search’ function. The screen on the Spectrum Analyzer should look

similar to that shown in Figure O3.

Figure O3: Sweep Test Marker Measurement Example

If the marker measurement doesn’t read 0.0 dBm, adjust the amplitude on the Signal Generator

until the Spectrum Analyzer marker reads 0.0 dBm, or as close to 0.0 dBm as possible. This will

remove all losses associated with the test cables. All measurement data should be recorded one

digit to the right of the decimal point, for example, 31.5dB.

Once the test setup is calibrated, these cables will remain in place and will be used

throughout the whole test. If the test cables are removed or changed, incorrect readings

will result.

RF Cable Insertion Loss

This test is performed on all RF cables that are installed in the system. This includes the eight

antenna cables, the system calibration cable, and all jumper cables. Follow the procedures for

either the cables on the ground or cables run up the tower.

Test Procedure For RF Cables on the Ground

Step 1. Ensure calibration of the test setup has been performed each time the test frequency is

changed.

Step 2. If present, remove the barrel connector from between the Signal Generator and

Spectrum Analyzer cables.

Step 3. Connect the cable from the Signal Generator to one end of the cable. Use a barrel

connector to change the gender, if required.

Step 4. Connect the cable from the Spectrum Analyzer to the other end of the cable. Use a

barrel connector to change the gender, if required.

Step 5. Take a marker measurement on the Spectrum Analyzer by using the ‘marker to peak’

or the ‘peak search’ function. The screen on the Spectrum Analyzer should look similar

to the one shown in Figure O4.

Figure O4: Insertion Loss (Cables on Ground) Marker Measurement Example

Step 6. The result should be within +/– 0.5 dB of the calculated value. If the insertion loss

results do not agree with the manufacturer’s data, check the connectors for proper

connection to the cable, and check for kinks in the cable. If the Spectrum Analyzer has

a distance to fault (DTF) function, it can be used to help troubleshoot kinks in the

cable.

CAUTION! Cables with results greater than the specified limits (i.e., 2 or 3 dB high)

should not be installed, as a potential hardware fault exists.

Step 7. Record the data in the RFS System Test Form under “MAIN FEEDER LOSS” or

“JUMPER LOSS”. Ensure that the information is recorded under the channel number

that is on the cable label.

Step 8. Repeat steps 3 through 7 for all remaining cables and jumpers.

Step 9. Change the frequency to the next test frequency (refer back to the Test Setup section of

these procedures). Perform steps 1 through 8 until all cables have been successfully

tested at the frequencies shown in Table O4.

Test Procedure For RF Cables Already Run Up the Tower

Step 1. Ensure calibration of the test setup has been performed each time the test frequency is

changed.

Step 2. If present, remove the barrel connector from between the Signal Generator and

Spectrum Analyzer cables.

Step 3. Have a member of the tower crew positioned on the tower, at the upper end of the

cables, connect the calibration cable to antenna cable 1 with a barrel connector.

Step 4. At the lower end of the RF cables, connect the cable from the Signal Generator to the

calibration cable. Use a barrel connector to change the gender, if required.

Step 5. Connect the cable from the Spectrum Analyzer to antenna cable 1. Use a barrel

connector to change the gender, if required.

Step 6. Calculate the marker using the following formula: (the length of BOTH the calibration

cable and the antenna cable) x (loss per foot at the RFS center frequency for the type of

cable used).

Step 7. Take a marker measurement on the Spectrum Analyzer by using the ‘marker to peak’

or the ‘peak search’ function. The screen on the Spectrum Analyzer should look similar

to the one shown in Figure O5.

Figure O5: Insertion Loss (Cables on Tower) Marker Measurement Example

Step 8. The result should be within +/– 0.5 dB of the calculated value. If the insertion loss

results do not agree with the manufacturer’s data, check the cable connectors for proper

connection to the cable, and check for kinks in the cable. If the Spectrum Analyzer has

a distance to fault (DTF) function, this can be used to help troubleshoot kinks in the

cable.

October 23, 2003

Step 9. Divide this value in half and assign the result to the calibration cable and to the antenna

cable.

Caution: Cables with results greater than the specified limits (i.e., 2 or 3 dB high) should

not be installed, as a potential hardware fault exists.

Step 10. Record the data in the RFS System Test Form under “MAIN FEEDER LOSS”. Ensure

that the information is recorded under the channel number that is on the cable label.

Step 11. Repeat steps 3 through 10 for antenna cables 2 through 8.

Step 12. When finished, take the average of the eight values obtained for the calibration cable.

Use this value for the insertion loss of the calibration cable.

Step 13. Change the frequency to the next test frequency (refer back to Test Setup). Perform

steps 1 through 12 until all cables have been successfully tested at the frequencies

given in Table O4.

Step 14. Check the value of the nine jumpers at all three frequencies, per the procedure for

cables on the ground. Record the data in the RFS System Test Form under “JUMPER

LOSS”. Ensure that the information is recorded under the channel number that is on the

cable label.

RFS Test Procedure

This procedure is performed twice for an installation. The first sweep is performed prior to

mounting the RFS on the tower. This test verifies that all the equipment is in tact from shipment.

These sweeps will need to be compared to the factory sweeps that are shipped with the RFS.

The second sweep is performed after the RFS has been mounted on the tower and the RF cables

have been connected. This sweep verifies that no damage was done to the RFS when hoisting it,

and that the RF cables are properly connected to the RFS.

Step 1. Perform the “Equipment Set-up”.

Note: When performing the transmit (TX) side tests on the RFS, the signal level from

the Signal Generator needs to be lowered to at least –20 dB. The RFS has protection

circuits built in and will disable the PAs in the RFS if the incoming signal is too high.

Step 2. Perform the “Equipment Calibration”.

Step 3. Configure the test equipment as shown in Figure O16.

Appendix P: Chassis Alarms

The chassis contains two connectors that are used to send alarm indications to the BTS. One of

the connectors, labeled CABINET ALARM, is used to trigger alarm conditions that occur within

the external chassis. The second connector, labeled BBU, is used to process alarms from the

battery backup unit. Both connectors contain six pins, which are numbered as shown in Figure

P1. This figure also shows the CAL and GPS-B connectors for size reference.

The alarm connector uses only four of the six pins. The pin names can be found in Table P1.

Table P1: Pin Names

Pin Name

1 General Fail Alarm

2 Ground reference for General Fail Alarm

3 Door Open Alarm

4 Ground reference for Door Open Alarm

5 Not Connected

6 Not Connected

The first pin of the alarm connector is the General Fail Alarm. This signal should be left open to

indicate an alarm condition from the HMC module located in the outdoor chassis. If no alarm

condition exists, this pin should be driven low. Pin 2 is used as the ground reference for this

alarm. The second alarm sent to the chassis is located on pin 3, Door Open Alarm. This signal

should be driven low when the door is closed. To indicate that the door of the outdoor chassis is

open, this signal should be left open. The associated ground reference for this signal is taken

from pin 4.

The BBU connector contains four alarm signals. These signal names are listed in Table P2.

Table P2: BBU Signal Names

Pin Name

1 Digital Ground Reference

2 BBU Battery Low

3 BBU Rectifier Fail

4 BBU AC Line Fail

5 BBU Charge Fail

6 Analog Ground Reference

The first alarm signal is located on pin 2, BBU Battery Low. If the BBUs battery is running low,

the signal on pin 2 should be left open. BBU Rectifier Fail alarm is the next alarm and is located

on pin 3. This signal should be left open to indicate a failure on the Battery Backup Unit’s

rectifier. The next alarm condition occurs if the AC Line to the BBU fails. In this condition,

signal BBU AC Line Fail on pin 4 should be left open. If the BBU is unable to hold a charge,

then the BBU Charge Fail signal on pin 5 should be left open. For non-alarm conditions (normal

operation), these signals should be driven low. The digital ground reference for these signals is

located on pin 3. The analog ground reference should be located on pin 4.

Appendix S: Single Antenna Test Procedure

Objective

The object of the RFS Single Antenna Test Procedure is to verify the functionality of each

antenna element in the Ripwave Radio Frequency Subsystem (RFS). The 8 antenna elements

work together to create the beamforming that results from using a Smart Antenna - Phased Array

technology. Using 8 combined single antenna elements creates the beamed radiation that is part

of what constitutes the gain of up to 18 dB during transmission of data.

Each antenna element has an associated (and hard cabled) RF/Power Amplifier (PA) card in the

Base Transceiver Station (BTS). In order to verify the correct beamforming and that each single

antenna is working properly, we have to turn off the individual PA that controls each antenna

element, one at a time.

The Single Antenna Test should be performed after completing an equipment check and after

performing the Base Station Calibration Verification* procedure described in the Ripwave Base

Station Installation & Commissioning Guide. This test is necessary since an equipment check

does not check the functionality of the RFS, and the Calibration Verification only sweeps for

losses in the RFS, not RFS functionality.

*Note: The Calibration Verification, where you check both transmit power and receive

sensitivity, is also sometimes referred to as the RF Sanity test.

More specifically, the Single Antenna Test checks the following:

1. Low Noise Amplifier (LNA) at the RFS. LNAs are an integral part of the smart antenna

technology.

2. Power Amplifiers. Each PA is a module in the BTS RF shelf that creates the RF

transmission. With one per element, there are a total of 8 PAs in the shelf. The

transmission is measured in dBm. This is what makes possible the transfer of data over-

the-air.

3. Modulations. As each antenna element is checked, the variable modulations are tested.

The higher the modulation, the higher the power and the better the data rate. The test

ensures that all modulations possible, i.e., QPSK, 8PSK, and QAM16, are working

properly.

Panel Procedure

Overview

Assuming the equipment has been installed and you have performed the calibration verification,

if the results were erroneous this Single Antenna Test will not be valid. It is important to

complete those two steps successfully before continuing.

For this test you will need two people. One person will verify the reception (Rx) of each antenna

using the Constellation Debugger Tool and a Modem. The following summarizes what will

happen during this test:

1. Person A will stay where the BTS or EMS is located. This person will control each PA in

the BTS to be tested.

2. Person B will be in the field. This person will pick a complete Line of Sight (LOS) test

point to the RFS (antenna). Person B will use the Constellation Debugger software

supplied by Navini. This software allows the tester to verify functionality.

3. Once the two people are in place, start by turning all antennas off except for Antenna #1.

NOTE: It does not matter which antenna you start with as long as the tester can keep

track of which ones have been tested and each one’s results.

4. With only one antenna powered on, Person B verifies the transmission, modulation, and

signal strength of the single antenna. Person B verifies this information for at least 30

seconds.

5. When the first antenna is checked, Person A saves the file and waits for Person B to

power on Antenna #2.

6. Steps 3 through 5 are repeated for each antenna element.

Details

The following provides more detail for each step, and includes snapshots of what to change and

what to measure.

Step 1. After calibration verifications are successful, in EMS click on the BTS tab and

highlight the specific BTS. Go to Air Interface > Layer 1, and click on the

Antenna Table tab (Figure S1). This window will show all antennas and their PA

status.

Step 2. After checking that all PAs are up and running, next click on Configure (Figure

S2). This function will take you to the configuration mode of this particular

window.

212 Part #40-00047-00 Rev F v1.0 (TTA)

October 23, 2003

Step 3. Click on the button, Modify All. This function will allow you to modify all

antennas and PAs at the same time. Notice that this window allows you to

configure any column shown here. For our purpose we will only use the second

column, Admin Status (Figure S3). This column shows the state of each PA that

controls each antenna in the RFS. “Up” means the antenna and PA are on and

functioning. “Down” means the antenna and PA are off and not transmitting.

Figure S3: Modify All

Step 4. Next, turn off (no transmission) all of the antennas and PAs except for Antenna #1.

This begins the verification of this antenna. Refer to Figure S4. When only

Antenna #1 is powered up and transmitting, the second person will verify at the

other end that the antenna is actually transmitting information to the Modem. This

can be completed by doing a Ping at the Modem side.

Part #40-00047-00 Rev F v1.0 (TTA) 213

October 23, 2003

Figure S4: Antenna #1 On

Step 5. Start a Ping with the Modem and PC performing the test, observing the

Constellation Debugger tool. Look for the following values:

?? ACC Signal Strength

?? Absolute Sync Signal

?? Processed Sync Signal

These values, an example of which is shown in Figure S5, give you an indication if

there is something wrong with the antenna. If the values are too low or you do not see a

response from your Ping, it means that the antenna and/or the PA are not functioning

properly.

Step 6. Repeat Steps 4 and 5 to verify each one of the antennas and the PAs. The

verification of each antenna concludes the testing procedure.

Comments & Suggestions

1. Navini Smart Antenna technology uses all the 8 antenna elements for the optimum

performance of the system. It is recommended that all antennas are verified and working

properly. If one of the antennas or PAs malfunctions or it breaks, the RFS will still work.

It will not work at its optimum operation, but it will still be functioning equipment. It is

recommended that you change or swap the bad board or equipment.

2. For the testing of each antenna it is recommended that you pick only one spot to measure

the Rx side of the RFS. This spot must to be at a distance of 2-3 km with clear line-of-

sight.

3. A difference of more than 2 dB between the Absolute and Processed SYNC Signal

strength, typically indicates the presence of multipath in the environment.

CPE Descriptor

Field Name Values Description

Name Name given to this CPE Descriptor.

Index 1 (1-8) Unique index identifier for this CPE Descriptor.

Priority 0 The priority that a CPE with this assigned Descriptor

will receive from the BTS Resource Manager software

when requesting RF resources. This field maps to the

Layer 2 > Bandwidth Data component in the BTS.

UL Max Bandwidth

(Kbps) 0, 32, 64, 96, 128, 160,

192, 224, etc. Maximum uplink bandwidth allowable for a CPE with

this Descriptor. The maximum number of code channels

allocated for a CPE is directly related to this field.

UL Min Bandwidth

(Kbps) 0, 32, 64, 96, 128, 160,

192, 224, etc. Minimum uplink bandwidth allowable for a CPE. This

field determines the number of code channels allocated

when a CPE begins a data session. The larger this value,

the more code channels allocated at session startup.

DL Max Bandwidth

(Kbps) 0, 32, 64, 96, 128, 160,

192, 224, etc. Maximum downlink bandwidth allowable for a CPE.

The maximum number of code channels allocated for a

CPE is directly related to this field.

DL Min Bandwidth

(Kbps) 0, 32, 64, 96, 128, 160,

192, 224, etc.

Minimum downlink bandwidth allowable for a CPE.

This field determines the number of code channels

allocated when a CPE begins a data session. The larger

this value, the more code channels allocated at session

startup.

Avg Queue Size Weight

(%) 100.0 How much the current queue size contributes to the

calculation of average queue size. The average queue

size is used by the BTS Resource Manager to determine

how many resources (code channels) to give a CPE. The

greater the weight, the greater influence the current

queue size has on the average queue size. The lower the

weight, the more the average queue size is an actual

average of the current queue size over time.

Max Queue Size (KB) 512 Maximum queue size for each priority queue (high, low,

voice). Once full (Max Threshold) all packets are

dropped.

Min to Max Drop

Probability (%) 10 The probability of a packet being dropped when the Min

Threshold has been reached. The higher this number, the

more likely a packet will be dropped between the Min

and Max Threshold. All packets are dropped at Max

Threshold.

Realtime Min Drop

Threshold (%) 100 The minimum queue size at which voice-priority packets

are considered for being dropped. For example, if set to

10% once the queue size reaches 11% or more, voice

priority packets may be dropped. The Max Threshold

Probability field determines if a packet is dropped once

the Min Threshold is exceeded.

High Priority Min Drop

Threshold (%) 100 The minimum queue size at which high-priority packets

are considered for being dropped. For example, if set to

10%, once the queue size reaches 11% or more, high

priority packets may be dropped. The Max Threshold

Probability field determines if a packet is dropped once

the Min Threshold is exceeded. continued…

Appendix V: Base Station Calibration Verification

Objective

The objective of this procedure is to verify the transmit power and noise figure of the Base

Station using a Modem.

Test Equipment Required

?? Installed Base Station, powered on and calibrated

?? Navini Drive Test Box

?? PC with Beamforming Display tool installed

?? 4 Fixed Attenuators: two at 30 dB, two at 10 dB.

Low power attenuator acceptable.

?? RF cables and adaptors (3 ft or more)

?? N type Terminator for GPS

Test Procedure

Step 1. If not already done, calibrate the Base Station. Verify a successful calibration by

monitoring the console with “caldebugon”. Verify that the cal error equals zero. If

cal errors are not zero, troubleshoot the system before starting.

Step 2. Prepare the setup that is shown in Figure V1.

Step 3. Connect approximately 30-40 dB of attenuation to one end of the calibration cable.

Connect a 3-6 ft RF cable to the other end of the attenuation. Connect 40 dB of

attenuation to the end of that cable. Connect the attenuators to the Navini Drive

Test box.

Step 4. Put the Drive Test box as far away from the Base Station as possible. Terminate

the GPS connector. Calculate the path loss from the Drive Test box to the Cal

cable. In the EMS disable carriers 1-2, 3-4, and 9-10, leaving 5-6 and 7-8 enabled.

Also verify that the ACC for 5-6 is selected. This is found by clicking on the BTS

tab, highlighting the specific BTS, then selecting Air Interface > Layer 2 >

Carrier data. Refer to Figure V2.

Step 5. Connect approximately 20-40 dB of attenuation to the end of the calibration cable.

Connect a 3-6 ft RF cable to the other end of the attenuation. Connect the

remaining attenuation to the end of that cable. Connect the attenuators to the

Navini Drive Test box.

Step 6. Put the Drive Test box as far away from the Base Station as possible. Terminate

the GPS connector. Calculate the path loss from the Drive Test box to the Cal

cable. In the EMS disable carriers 1-2, 3-4, and 9-10, leaving 5-6 and 7-8 enabled.

Also verify that the ACC for 5-6 is selected. This is found by clicking on the BTS

tab, highlighting the specific BTS, then selecting Air Interface > Layer 2 >

Carrier data. Refer to Figure V2.

Step 7. Disable all PAs except PA #1.

Step 8. From the Beamforming, verify that the Receive Sync from the Drive Test Tool is

approximately –80 dBm. If not, adjust the value of the attenuators accordingly.

Step 9. Start an upload of a large file or ping continuously with packets 3,000 bytes or

greater. You need to acquire at least 20 code channels in one sub-carrier. If the

number of code channels is less than 20, start an additional ping sessions.

ping <ip_address> –l 3200 –t

Step 10. Capture the following parameters from the BTS Beam-forming display. Refer to

Figure V3:

Downlink: SYNC Recv Sgl Strength (dBm)

Uplink: SNR (dB)

Uplink: TCC Recv Sgl Strength (dBm)

Step 11. Capture the same parameters as in Step 10 for each of the remaining PAs, one by

one. That is, with PA #2 turned on and all other PAs turned off ; then with PA #3

turned on and all other PAs turned off; etc.

Step 12. Use the spreadsheet and input all the captured parameters to calculate the Tx

power and Noise figure.

Step 13. Measure and record attenuation value.

IV. Section 4: Transmitter Performance

A. Analyzer Readings (A90-B97)

1. Peak

The peak amplitude of the sync signal measured on the spectrum analyzer.

The measurement is taken with the spectrum analyzer in the time domain (0

Hz span) and RBW set for 5 MHz. Sweep time is typically between 10 and 20

ms. When taking the measurement, the sync signal will have peaks and

valleys associated with it. Make sure to measure the absolute peak.

2. RMS

This is a calculated value based on measurements taken on several occasions,

comparing peak power to RMS power on a Rhode & Schwartz spectrum

analyzer. It has been determined that the correction factor for peak to average

on a standard spectrum analyzer is 9.5 dB. This correction factor is the default

entry in this section. If it is possible to make the RMS measurement with the

proper equipment then that is the preferred method. The calculation is very

straightforward: peak power minus 9.5 dB = Power RMS.

B. P out transceiver (D90-E97)

Power peak and Power RMS are calculated values using the value from the spectrum

analyzer readings and the value entered for coupler/test cable loss (Cell H31).

C. Power at antenna (RMS) (G90-G97)

Calculated value using the Output Power (Pout) of the transceivers and the Cable Loss

plus the inherent loss of the RFS.

D. Radiated Power (RMS) (I90-I97)

Calculated value using Power at the antenna and the value entered for antenna gain

(Cell H32).

E. TX Gain (DAC word)

The hex data generated during calibration for the transmit gain DAC that controls the

IF attenuator. This is found in the EMS under Air interface > Layer 1 > Show

configuration > Antenna tab.

F. Max power deviation across all antennae (E99, G99, I99)

Calculated value showing the deviation between the lowest power antenna and the

highest power antenna for each column.

Equipment Settings

Part of the Test Procedures below.

Test Procedure Setup

Set up the test procedures, per the following.

Step 1. Calibrate the BTS and perform the Calibration Verification procedure.

Connect the Modem and the attenuators. The combined attenuation should be set roughly as

follows:

Total attenuation = PTX - 30 + 18 – Cal cable loss + 80

Where PTX is the Tx output power at antenna input port that is set in EMS during

calibration. Cal cable loss is the loss of the calibration cable.

The total attenuation should be partitioned between fixed and adjustable attenuators in

such a way that the adjustable attenuator is set to about 10 dB.

Disconnect the calibration cable from the back of the BTS shelf and connect it to the attenuator

as shown in the drawing

Ping the BTS continuously from the Modem.

Check the sync level at the CPE debug tool. The level should be about –80 dBm.

Test Procedure - Check Modem Sensitivity & Output Power

Follow the steps in the procedure below.

Step 1. Record the downlink TCC power level and SNR reading on the CPE debug tool.

Step 2. Calculate the effective noise floor: NF= SNRTCC – LevelTCC.

Where SNRTCC is the TCC SNR and LevelTCC is the received downlink TCC level.

NF should be close to –127 ±5.

Step 3. Check Modem output power cap difference. It should be greater than 0.

Step 4. Increase the attenuation by 10 dB (increase the attenuation of the adjustable

attenuator).

Step 5. Measure the effective noise floor and the output power cap difference gain.

Step 6. Increase the attenuation by another 10 dB and take the measurements again (if the link

is broken when the attenuation increases 10 dB, back off the attenuation by 10 dB and

then increase the attenuation with 1 dB steps until the link is broken. Then reduce the

attenuation by 4 dB).

Navini Networks, Inc. Ripwave Base Station I&C Guide

Part #40-00047-00 Rev F v1.0 (TTA) 253

October 23, 2003

Step 7. Calculate the maximum path allowed as follows:

Max loss = Attenuation total + Cal cable loss + 30

Where Attenuation total is the total attenuation of all attenuators (fixed + adjustable).

Test Procedure - Check BTS Sensitivity (Individual Antenna)

Step 1. Set the attenuation of the attenuator so the total attenuation is about

PTX – 30 – Cal cable loss + 80.

Step 2. Activate antenna #1 only.

Step 3. Record the uplink TCC power level and SNR reading on the BTS debug tool.

Step 4. Calculate the effective noise floor: NF = SNRTCC – LevelTCC.

Where SNRTCC is the TCC SNR and LevelTCC is the received downlink TCC level.

NF should be close to: SNR – BTS Sensitivity + 25 ±?5.

Where BTS sensitivity is the BTS sensitivity setting during calibration.

Step 5. Record the Modem output power.

Step 6. Increase the attenuation by 10 dB (increase the attenuation of the adjustable

attenuator).

Step 7. Measure BTS effective noise floor and Modem output power again.

Step 8. Increase the attenuation by another 10 dB and take the measurements again (if the link

is broken when the attenuation increases 10 dB, back off the attenuation by 10 dB and

then increase the attenuation with 1 dB steps until the link is broken. Then reduce the

attenuation by 4 dB. The same attenuation will be used for all antenna tests).

Step 9. Calculate the maximum path allowed as follows:

Max loss = Attenuation total + Cal cable loss + 30

Where Attenuation total is the total attenuation of all attenuators (fixed + adjustable).

Step 10. Repeat the steps for antennas 2 through 8.

Step 11. Average the Modem output power over antennas 1 through 8 for each attenuation

setting.

Test Procedure - Check BTS Sensitivity (Antenna Array)

Step 1. Set the initial attenuation the same as in the individual antenna testing procedure.

Step 2. Activate all antennas.

Step 3. Record the uplink TCC power level and SNR reading on BTS debug tool.

Ripwave Base Station I&C Guide Navini Networks, Inc.

254 Part #40-00047-00 Rev F v1.0 (TTA)

October 23, 2003

Step 4. Calculate the effective noise floor: NF = SNRTCC – LevelTCC.

Where SNRTCC is the TCC SNR and LevelTCC is the received uplink TCC level.

NF should be close to SNR – BTS Sensitivity + 25 ±?5.

Where BTS sensitivity is the BTS sensitivity setting during calibration.

Step 5. Record the CPE output power.

Step 6. Increase the attenuation by 10 dB (increase the attenuation of the adjustable

attenuator).

Step 7. Measure BTS effective noise floor and Modem output power again.

Step 8. Increase the attenuation by the same amount as in individual antenna tests and measure

the BTS effective noise floor and Modem output power.

Step 9. For each attenuation setting, the Modem output power should be 9 dB less compared to

those (average) in individual antenna tests.

Step 10. Increase the attenuation by another 18 dB. The link should be on.

Step 11. Calculate the maximum path allowed as follows:

Max loss = Attenuation total + Cal cable loss + 30

Where Attenuation total is the total attenuation of all attenuators (fixed + adjustable).

Test Procedure - Data Rate

Step 1. Set the attenuation of the attenuator so the total attenuation is about

PTX – 30 +18 – Cal cable loss + 80.

Step 2. Activate all antennas.

Step 3. FTP a file with size greater than 10 Mbps from Modem to BTS (uplink).

Step 4. Check the uplink data rate. It should be approximately 1 Mbps.

Step 5. FTP a file with size greater than 20 Mbps from BTS to Modem (downlink).

Step 6. Check the downlink data rate. It should be approximately 2 Mbps.

After the test is completed, reconnect the calibration cable back to the BTS and run the

calibration. The new calibration table should be the same as before (the changes in Tx and Rx

AGC should be within 2 bits).

Appendix X: Drive Study

Overview

The Drive Study is performed to confirm Base Station coverage. It is used to validate that the

Base Station can be “seen” by a Modem throughout its predicted coverage area.

The RF coverage analysis displays areas of coverage from “good” to “bad” by the use of color-

coding. An RF coverage analysis and its legend may be seen in Figure X1. The legend on the left

displays the decibel strength for a given area, with red designating ‘good coverage’ and white

designating ‘bad coverage’. The RF coverage analysis is used to map out the Drive Study route

(Figure X2), along with geographic areas of concern. You should pay particular attention to null

(white) areas and the cell edges.

Drive Test Procedure

While driving you will collect statistics to validate the coverage plot. The application takes a

reading every second and records the data in comma delimited file format. It is important to

ensure that the GPS is on and that you can see the GPS coordinates in the application.

Since the Ripwave system is not a mobile system, do not exceed 10 mph during the Drive Study.

Going any faster will negate the adaptive beamforming, as the vehicle will not be in the exact

position calculated by the Base Station.

Step 1. Ensure that the Base Station has successfully completed calibration and RF sanity

measurements at the frequency and TX/RX signal levels that were determined during

the site survey. Ensure that the Base Station is powered on and able to TX/RX data.

Step 2. Create a CPE Descriptor, and assign it to the Modems to be used for the Drive Study:

CPE Descriptor Parameters

Name: Drive Study

Index: Next available number

Priority: 1

UpLink Max Bandwidth: 64

UpLink Min Bandwidth: 32

DownLink Max Bandwidth: 96

DownLink Min Bandwidth: 64

Other parameters: Use defaults.

Step 3. Mount an omni-directional antenna on the roof of the vehicle. This will serve as the

antenna for the Modem.

Step 4. Bring the RF cable from the omni-directional antenna into the vehicle through the

window. Attach the antenna to the antenna input of the Modem. The rotating upright

antenna on the Modem needs to be removed to perform this step. You will also need to

Appendix Y: Location (FTP) Tests

Introduction

The Location, or FTP, Test is performed to check the Ripwave system operation through file

transfers between the Base Station and the Modem. The test measures the data rate performance

at various locations within the coverage area. Data throughput is measured by executing file

transfers using the FTP protocol for both upstream and downstream links. A file server must be

in place on the same subnet with the BTS to accurately perform the file transfer, and the CPE

User computer must be loaded with an FTP Client. As the file transfer is running, a data file is

captured by the Modem tool. Data rates are captured by the FTP program.

Data is recorded in a spreadsheet format. The spreadsheet lists the location, GPS, and other

information. As data rates are captured, the results are entered manually. An average SNR and

sync RSSI can be read from the debug tool, and recorded, for quick comparison to the acceptable

criteria (see “Acceptable Criteria” section of this appendix). For NLOS indoor locations, tests are

performed both outside the building and inside, so that the obstruction loss for the building can

be determined. Unless the customer can provide indoor access, all results will be LOS or Near

NLOS.

Planning the Locations

Before the actual testing is conducted, you will need to select the locations for the testing to

occur. The sites should meet specific criteria and include a mixture of the following

environments:

?? High Power (A), low clutter; close in, residential

?? High Power (A), high clutter; close in, commercial

?? Medium Power (B), low clutter; mid-range, residential

?? Medium Power (B), high clutter; mid-range, commercial

?? Low Power (C), low clutter; distant, residential

?? Lower Power (C), high clutter; distant, commercial

Where:

(A) High Power = Sync Value greater than –70 dBm

(B) Medium Power = Sync Value between –70 dBm and –85 dBm

October 23, 2003

At least 5 test points for each type are attempted. This may be difficult, depending upon the

actual deployment scenario. Results may yield a very large percentage in one of the categories.

For selecting an even spread across a 120-degree sector for a panel antenna installation, divide

the 120 degrees into 6 even slices of 20 degrees each. Then divide each slice into 2 Km

segments. This spaces each location at an approximate even distance throughout the complete

sector and yields 36 test sites.

To select an even spread across a 360-degree cell for an omni antenna installation, divide the

360-degree cell into 12 even slices of 30 degrees each. Next, divide each slice into segments

based on distance (1 Km or 2 Km, depending upon propagation). This will approximately space

each location an even distance from each other throughout the complete cell, yielding

approximately 48 test sites (based on a 4 Km cell radius). To do this, split the cell into 4

quadrants. Using the RF coverage analysis, select up to 16 locations per quadrant (Figure H1).

Pay particular attention to null areas and the cell edges. At these locations you will perform a file

transfer to measure the data rates available. The FTP/Location Test Tool program and the BTS

Beamforming Display tool will be used to record RF parameters during each test. Figures Y1 and

Y2 provide examples of simple guidelines for selecting an even spread across a cell area.

Acceptable Criteria

In order to evaluate the test results, several criteria are reviewed. These criteria are valid for both

LOS and NLOS measurements.

?? Processed Sync Signal Strength: For a given test location, ± 2 dB variation during FTP

?? Absolute Sync Signal Strength – Processed Sync Signal Strength: not greater than 2 dB

variation during FTP

?? SNR values consistent during the FTP for all carriers used:

a. QPSK: at least 11 dB

b. 8 PSK: at least 14 dB

c. QAM16: at least 17 dB

?? UL and DL Packet Error Rates (PER) not greater than 1%. This will vary according to

interference levels, but may not render the system inoperable.

?? Uplink Beamforming Gain: between 16 dB and 21 dB. Perform a comparison of UL and DL,

Beamforming Gain differences should be not greater than 3 dB.

C D

Ripwave Base Station I&C Guide Navini Networks, Inc.

266 Part #40-00047-00 Rev F v1.0 (TTA)

October 23, 2003

?? Modem Transmit Power < 25 dBm; BTS Transmit Power < 0 dBm per code channel with

power control

?? Sync vs. Data Rate:

Absolute Sync (dBm) UL Data Rate (Mbps) DL Data Rate (Mbps)

(A) –55 to –70 0.6 to 1.0 1.5 to 2.0

(B) –70 to –85 0.5 to 1.0 1.2 to 2.0

Process

The recommended process for performing the Location (FTP) tests is described below.

First: Verify that a single Modem transmits and receives data at expected rates, as indicated

previously.

Second: Verify that multiple Modems simultaneously transmit and receive data at acceptable

rates, and the parameters listed above are being met. NOTE: The exact number of Modems is

determined by field conditions. The minimum is two.

Third: Verify operation at the full range of the system*. Include LOS Location Tests at cell

edges. The height of Modem and uplink and downlink data rates are recorded for each site. Data

rates are to be compared with expected results, as seen in the last item (Sync vs. Data Rate) of

Acceptance Criteria. For example:

*2.6 GHz : ~12 Km

*2.4 GHz: ~ 3 Km

Equipment Required

?? Laptop computer

?? GPS with serial cable

Location (FTP) Test Procedure

Two people are needed to perform this procedure. One will be in the car performing the location

test, and the other will be at the Base Station checking the operation using the BTS Beamforming

diagnostic tool.

1. Ensure that the Base Station has successfully completed calibration, RF sanity

measurements, and the Drive Study at the frequency and TX/RX signal levels that were

determined by the cell site survey. Also ensure that the Base Station is powered on and is

able to transmit and receive data.

2. Connect the DC to AC power converter to the power port in the vehicle.

3. Connect the Modem power supply to the CPE and to the DC to AC power converter.

4. Connect the Ethernet cable to the Ethernet port on the laptop computer and to the Ethernet

port on the Modem.

5. Connect the GPS to the serial port on the laptop computer.

6. Drive to one of the locations selected on the RF coverage analysis. Stop and turn off the

vehicle.

7. Power on the GPS, the Modem, and the laptop computer. Place the Modem on the roof of the

vehicle.

8. Start the Navini Networks FTP/Location Test Tool program.

9. Verify that the Base Station is transmitting and that the Modem establishes sync and can

communicate with the Base Station. Ping a device address on the network side of the Base

Station, and verify that a reply is received. While monitoring the Constellation Debugger,

position the Modem to reduce the difference between absolute sync and processed sync

levels to 2 or less.

10. Enter a memo into the comment field about which link of the test is being performed.

11. Verify that the GPS input is seen in the application.

12. Put the location number/site identifier into the comment field of the Navini Networks

Constellation Debugger, and press the Enter key. This will identify the site location.

13. On the EMS connected to the Base Station, start the BTS Beamforming diagnostic tool.

14. From the laptop computer with the Modem connected to it, start a downlink FTP file transfer.

Record the results on the site page or in the log.

15. On the EMS connected to the Base Station, using the BTS Beamforming diagnostic tool

verify the strength and direction of the beam during the file transfer. Record the results on the

site page or in the log.

16. Repeat the file transfer three times, stopping and starting the Debugger and Beamforming

tool for each transfer

17. Repeat steps 14-15, this time performing an uplink FTP transfer.

October 23, 2003

18. When finished, remove the Modem from the roof and secure equipment for travel.

19. Drive to the next location selected on the RF coverage analysis. Stop, and turn off the

vehicle.

20. Repeat steps 7 to 19 until all locations are tested. At this point send this data to the RF

Engineers to analyze, or continue until each quadrant in the cell is complete. When you send

the results depends upon the schedule or results from the file transfers.
