Navini Networks, Inc. Ripwave Base Station I&C Guide Part #40-00047-00 Rev F v1.0 (TTA) 181 October 23, 2003 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. Figure O1: Pin Layout A B C D E F G H J K L M

Ripwave Base Station I&C Guide Navini Networks, Inc. 186 Part #40-00047-00 Rev F v1.0 (TTA) October 23, 2003 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.
Navini Networks, Inc. Ripwave Base Station I&C Guide Part #40-00047-00 Rev F v1.0 (TTA) 187 October 23, 2003 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.
Ripwave Base Station I&C Guide Navini Networks, Inc. 188 Part #40-00047-00 Rev F v1.0 (TTA) October 23, 2003 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.
Navini Networks, Inc. Ripwave Base Station I&C Guide Part #40-00047-00 Rev F v1.0 (TTA) 189 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 Box Setup Step 1.

Refer to Figure O15. Step 1. Calibrate the test equipment. Step 2. Connect Signal Generator to cable 1 on the RFS side to the RF cable. Step 3. Connect spectrum analyzer to cable 1 on BTS side of RF cable. This will be done with the test cable and the QMA/SMA adapter. Step 4. Enable the RF on the signal generator. Step 5. From the Delta marker found in Step 1 take the loss reading in db. Record the results. Step 6. Perform steps 2 through 5 for all cables. Figure O15: RF Cable Test RF CableBTS End RFS EndQMA N-Type 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. ?? Spectrum Analyzer to the Cal Port ?? Signal Generator to the test equipment port of the test box. ?? Test box RFC/RFS port to the antenna

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. Figure P1: Pin Orientation 1 2 34561 2 3456
Ripwave Base Station I&C Guide Navini Networks, Inc. 204 Part #40-00047-00 Rev F v1.0 (TTA) October 23, 2003 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.

Navini Networks, Inc. Ripwave Base Station I&C Guide Part #40-00047-00 Rev F v1.0 (TTA) 209 October 23, 2003 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.
Ripwave Base Station I&C Guide Navini Networks, Inc. 210 Part #40-00047-00 Rev F v1.0 (TTA) October 23, 2003 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.

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. Figure S2: Configure Antenna Table
Ripwave Base Station I&C Guide Navini Networks, Inc. 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.
Navini Networks, Inc. Ripwave Base Station I&C Guide 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.
Ripwave Base Station I&C Guide Navini Networks, Inc. 214 Part #40-00047-00 Rev F v1.0 (TTA) October 23, 2003 Figure S5: Constellation Debugger Values 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.
Navini Networks, Inc. Ripwave Base Station I&C Guide Part #40-00047-00 Rev F v1.0 (TTA) 215 October 23, 2003 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.

Navini Networks, Inc. Ripwave Base Station I&C Guide Part #40-00047-00 Rev F v1.0 (TTA) 243 October 23, 2003 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.

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.

Ripwave Base Station I&C Guide Navini Networks, Inc. 252 Part #40-00047-00 Rev F v1.0 (TTA) October 23, 2003 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).

Navini Networks, Inc. Ripwave Base Station I&C Guide Part #40-00047-00 Rev F v1.0 (TTA) 257 October 23, 2003 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.

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.
Navini Networks, Inc. Ripwave Base Station I&C Guide Part #40-00047-00 Rev F v1.0 (TTA) 259 October 23, 2003 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 disconnect the patch antennas inside (Figure X3).

Navini Networks, Inc. Ripwave Base Station I&C Guide Part #40-00047-00 Rev F v1.0 (TTA) 263 October 23, 2003 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 (C) Low Power = Sync Value between –85 dBm, and –95 dBm
Ripwave Base Station I&C Guide Navini Networks, Inc. 264 Part #40-00047-00 Rev F v1.0 (TTA) 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. Figure Y1: Example of a 3-sector Site

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.
