Kimball respectfully submits this Findings Report for Broadband Field Testing (Findings Report) to the State of West Virginia Geological and Economic Survey and the Office of GIS Coordination (State). The State contracted with L.R. Kimball to provide broadband data verification tasks including statewide wireless broadband field testing. In August 2013, L.R. Kimball performed testing in the Region 9 Eastern Panhandle Regional Planning and Development Council area consisting of Berkeley, Jefferson and Morgan Counties, West Virginia. The broadband field testing consisted of drive-testing the three county area while using specific app-enabled smartphones provided by the State. The purpose of this testing was to assess the spatial and attribute accuracy of the service area polygons that four providers, AT&T, ntelos, US Cellular and Verizon, submitted to West Virginia in March 2013 as part of the National Telecommunications Information Agency (NTIA) State Broadband Data and Development Program (SBDD). Comparisons between the field data collected and the provider-supplied service area polygons facilitated the identification of possible coverage and speed inaccuracies reported to the State by the providers. This findings report will discuss the methodology associated with the field collection and the results of said field collection. The balance of this page is intentionally blank. September 2013 Page 1 1. METHODOLOGY The drive-testing phase of this project was initiated August 19, 2013 in Petersburg, West Virginia. It continued through August 22, 2013, with four days of field data collection, where L.R. Kimball field specialists spent a minimum of 10 hours each day driving through Berkeley, Jefferson and Morgan Counties. L.R. Kimball field specialists consisted of one two-person team, where one member served as the driver and the other as the navigator and data collector. 1.1 Initial Data Collection Prior to drive-testing, L.R. Kimball prepared geographic information system (GIS) data layers to make the drive-testing more efficient and improve the quality of the data collected. These layers include the following: West Virginia Statewide Addressing and Mapping Board (WVSAMB) 2011 Centerlines, with pre-determined Drive Centerlines chosen prior to field work West Virginia Statewide Addressing and Mapping Board 2011 Structures West Virginia Statewide Addressing and Mapping Board 2011 Imagery NTIA Round 7 Wireless Data Coverage Submission Speed Test Point Locations In addition, the State provided four smartphones for use during the drive-testing: AT&T Samsung Galaxy S III West Virginia PCS Alliance (ntelos) Samsung Galaxy S US Cellular Samsung Galaxy S III Verizon Samsung Galaxy S III All of these phones were updated with the QoS Solutions Android Applications that measure carrier connectivity, also provided by the State. The State asked L.R. Kimball to visit each planning and development council regional office during the initial stages of the fieldwork collection to discuss the objectives of the project and gain feedback from the region regarding specific areas of broadband concern within the region. L.R. Kimball field team met with Mr. Matt Mullenax, Transportation Planner/GIS Analyst on August 21, Mr. Mullenax requested that the field team add a speed test point in a small community in the northern part of Jefferson County West Virginia Statewide Addressing and Mapping Board 2011 Centerlines The WVSAMB 2011 Centerlines were downloaded from the West Virginia GIS Technical Center Website. The centerlines were then evaluated for potential use. Removed from the dataset were named driveways and dead-end streets. The centerlines were further reviewed and potential Drive Centerlines for the region were chosen. These potential Drive Centerlines were chosen based on several factors. They are a good representation within the submitted coverage areas. Also, they have residents living on them and did not appear to be fade-away roads (dirt roads that ultimately lead to nothing). In general, interstates were not included in the potential Drive Centerlines coverage because it is anticipated that they will be traveled/measured during normal travel to various locations and did not need to be formally routed. September 2013 Page 2 Figure 1 Initial WV SAMB 2011 Centerlines with Proposed Drive Centerlines West Virginia Statewide Addressing and Mapping Board 2011 Structures The WVSAMB 2011 Structures were downloaded from the West Virginia GIS Technical Center Website to use as reference only. There were no changes made to this layer prior to or during drive-testing Speed Test Points The QoS applications allow for a carrier broadband speed test to occur every five minutes, or at user-selected points. As the application requires remaining in the same location until the test completes, and does not produce accurate results if traveling above 25 mph, QoS recommended selecting random test point locations to run the application throughout the region. L.R. Kimball chose random points in populated areas as a test of the broadband speeds in submitted coverage areas. The initial speed test point layer contained 29 speed test locations in Region 9. September 2013 Page 3 Figure 2 Initial Speed Test Point Locations West Virginia Statewide Addressing and Mapping Board 2011 Imagery The WVSAMB 2011 Imagery was downloaded from the West Virginia GIS Technical Center Website for Region 9 counties to use as reference only. There were no changes made to these layers prior to or during drive-testing QoS Solutions Android Applications The QoS Solutions software that was provided by the State consisted of four Android Applications for use with smartphones. QCarrier measures carrier signal strength while driving with collected data stored directly on the phone. Rate of vehicle speed is not a factor in measuring signal strength. QWiFi locates and records Wi-Fi services with collected data stored directly on the phone. Rate of vehicle speed is not a factor in measuring Wi-Fi services. QPerf measures carrier connectivity at specific locations or during specific intervals with collected data stored on the September 2013 Page 4 QoS Website. Rate of vehicle speed is a factor in measuring signal strength. QMapper is a mapping device used in urban areas where you want a more accurate reading of your location. It does not store any data, and is to be used as a physical location reference tool.

Kimball field technicians to use with the US Cellular network Verizon Samsung Galaxy S III Phone The State provided a Samsung Galaxy S III smartphone for L.R. Kimball field technicians to use with the Verizon network. 1.2 Field Data Collection L.R. Kimball field technicians spent four days drive-testing in Berkeley, Jefferson and Morgan Counties for the State. Equipment included a laptop computer pre-loaded with Environmental System Research Institute s (ESRI) ArcMap 10.1 software and the WV SAMB 2011 centerline, drive centerline, speed test point, and orthophotography layers, a GPS to use for reference and four smartphones provided by the State. In addition, a power inverter was used in the vehicle to keep all of the equipment charged while testing. The L.R. Kimball field technician team consisted of a driver and a navigator. The navigator was responsible for mapping the route taken, as well as keeping track of the roads that were traveled and the points where speed tests were taken Roads Traveled Approximately 482 miles of roads were tested in Region 9 for carrier connectivity. The goal was to drive-test the carrier submitted NTIA wireless polygons using a good representation of roads without back-tracking a great deal. The terrain was what was expected for this section of Appalachia, with numerous mountainous and valley areas. In September 2013 Page 5 some instances, anticipated road and/or weather conditions prevented the driver from traveling certain roadways and the initial drive centerlines and speed test locations in those areas were adjusted accordingly. Figure 3 Roads Traveled During Drive-Testing Speed Test Point Validation There were a total of 30 speed test locations verified within Region 9. September 2013 Page 6 Figure 4 Final Speed Test Point Locations September 2013 Page 7 2. TEST RESULTS The drive-testing in Region 9 using smartphones was expected to show that good service exists in the urban areas and poor service in the rural areas of the region. In addition, it was expected that each of the providers being tested would have the service advertised in their NTIA submitted round 7 wireless coverage boundaries within the region. The QoS Software applications were user-friendly. It was easy to install the apps on the smartphones, and touching their icons on the screen opened them as expected. Analysis of the QoS Software application results involved the converting of.xml and.csv files into geodatabases and then making the appropriate comparisons. 2.1 QPerf Test Results The QPerf application is a measure of carrier connectivity at specific locations, or speed test points. Data was uploaded to the QoS Website during the test. The data from the Website was downloaded as.csv files and converted into a geodatabase. The downstream and upstream speeds were then converted to the appropriate NTIA tier to match the Round 7 Wireless Coverage Polygons submitted by wireless providers as part of NTIA s Round 7 data collection effort. Analysis consisted of a location comparison, whereby the plotted locations of the test points were compared against their respective R7 coverage layer, as well as a comparison of the downstream and upstream speeds of the test points against the maximum speeds reported to the NTIA. Figure 5 NTIA Speed Tiers AT&T QPerf Results Of the 30 speed test point locations within Region 9, 30 were located within the Round 7 wireless coverage polygon submitted by AT&T and should have obtained QPerf speed test results. However, only 20 test points obtained results using the AT&T mobile network within Region 9 and all of them were within the AT&T submitted coverage polygon. Maximum advertised downstream values for the entire area are a value of four on the NTIA Speed Tier and maximum advertised upstream values for the entire area are a value of three on the NTIA Speed Tier. Of the 20 test September 2013 Page 8 points obtaining results within the submitted coverage polygon, 17 met or exceeded the maximum advertised value for downstream coverage and 12 met or exceeded the maximum advertised value for upstream coverage. Figure 6 AT&T Downstream Speed Values September 2013 Page 9 Figure 7 AT&T Upstream Speed Values ntelos QPerf Results Of the 30 speed test point locations within Region 9, none were located within the Round 7 wireless coverage polygon submitted by ntelos. However, 24 test points obtained results using the ntelos mobile network within Region 9. September 2013 Page 10 Figure 8 ntelos Downstream Speed Values September 2013 Page 11 Figure 9 ntelos Upstream Speed Values US Cellular QPerf Results Of the 30 speed test point locations within Region 9, 27 were located within the Round 7 wireless coverage polygon submitted by US Cellular and should have obtained QPerf speed test results. However, only 22 test points obtained results using the US Cellular mobile network within Region 9. Of these 22 points, 21 were within the US Cellular submitted coverage polygon and one was not within the US Cellular submitted coverage polygon. Maximum advertised downstream values for the entire area are a value of three on the NTIA Speed Tier and maximum advertised upstream values for the entire area are a value of two on the NTIA Speed Tier. Of the 21 test points obtaining results within the submitted coverage polygon, 15 met or exceeded the maximum advertised value for downstream coverage and 20 met or exceeded the maximum advertised value for upstream coverage. September 2013 Page 12 Figure 10 US Cellular Downstream Speed Values September 2013 Page 13 Figure 11 US Cellular Upstream Speed Values Verizon QPerf Results Of the 30 speed test point locations within Region 9, 25 were located within the Round 7 wireless coverage polygon submitted by Verizon and should have obtained QPerf speed test results. However, only 14 test points obtained results using the Verizon mobile network within Region 9. Of these 14 points, 13 were within the Verizon submitted coverage polygon and one was not within the Verizon submitted coverage polygon. Maximum advertised downstream values for the entire area are a value of seven on the NTIA Speed Tier and maximum advertised upstream values for the entire area are a value of five on the NTIA Speed Tier. Of the 13 test points obtaining results within the submitted coverage polygon, nine met or exceeded the maximum advertised value for downstream coverage and nine met or exceeded the maximum advertised value for upstream coverage. September 2013 Page 14 Figure 12 Verizon Downstream Speed Values September 2013 Page 15 Figure 13 Verizon Upstream Speed Values 2.2 QCarrier Test Results The QCarrier application is a measure of signal strength along the roads that were traveled during drive-testing. A record is created every 10 seconds or whenever the signal strength changes, and is stored in an.xml file directly on each phone. In general, it was found that there is acceptable coverage within the urban areas of the region and very limited coverage in the rural parts of the region for all carriers. Attributes used for analysis include the RSSI_DM field which is Received Signal Strength Indication, measured in DBm, and the EC/IO field, which is the signal strength relative to interference, measured in db* AT&T QCarrier Results There were 12,282 points plotted within the AT&T network in Region 9. There were 429 points that obtained no data, indicating no signal strength. The signal strength ranged from -69 to -113 DBm. There was no EC/IO data collected September 2013 Page 16 for these points, as AT&T uses a Global System for Mobile Communication (GSM), which does not measure this value. The final drive centerlines shown with no phone data overlaid indicate areas where the phone was not able to connect to a GPS satellite, had no cellular service, and was not able to track the location of the phone. Figure 14 AT&T QCarrier Results, Based on RSSI_DM ntelos QCarrier Results There were 17,390 points plotted within the ntelos network in Region 9. The signal strength ranged from -48 to -105 DBm. The EC/IO data ranged from -90 to -160, with the majority of points falling at This indicates areas where calls cannot connect, or calls are dropped constantly. 1 The final drive centerlines shown with no phone data overlaid 1 September 2013 Page 17 indicate areas where the phone was not able to connect to a GPS satellite, had no cellular service, and was not able to track the location of the phone. Figure 15 ntelos QCarrier Results, Based on EC/IO US Cellular QCarrier Results There were 12,910 points plotted within the US Cellular network in Region 9. The signal strength ranged from -54 to -125 DBm. The EC/IO data ranged from -5 to EC/IO data of -160 indicates areas where calls cannot connect, or calls are dropped constantly. 2 The final drive centerlines shown with no phone data overlaid indicate areas where 2 September 2013 Page 18 the phone was not able to connect to a GPS satellite, had no cellular service, and was not able to track the location of the phone. Figure 16 US Cellular QCarrier Results, Based on EC/IO Verizon QCarrier Results There were 12,796 points plotted within the Verizon network in Region 9. The signal strength ranged from -59 to DBm. The EC/IO data ranged from -10 to EC/IO data of -160 indicates areas where calls cannot connect, or calls are dropped constantly. 3 The final drive centerlines shown with no phone data overlaid indicate areas where the phone was not able to connect to a GPS satellite, had no cellular service, and was not able to track the location of the phone. 3 September 2013 Page 19 Figure 17 Verizon QCarrier Results, Based on EC/IO 2.3 West Virginia Broadband Mapping Survey Results As requested by the Region, LR Kimball is providing a summary of participation results for the West Virginia Broadband Mapping Program s Broadband Survey program. Residents of West Virginia have been asked to provide feedback to the State regarding their broadband access. There are two surveys available. One is for broadband feedback, and one is to measure broadband speed at a specific location. The surveys are located at and As of June 1, 2013, 272 residents participated in the survey by taking the broadband survey, 283 residents participated by taking the speed test and 142 residents provided user feedback through the broadband survey website. These results are on a statewide basis. September 2013 Page 20 Region 9 had a total of 215 participants: 30 provided user feedback, 77 took the broadband survey and 108 took the speed test. Of the 30 residents providing user feedback, 22 indicated that the map shows that broadband is available, but in reality it is not available at their residence. The remaining eight pa
