9-1-1 Location Accuracy

  1. 1. 9-1-1 Location Accuracy and FCC’s Fourth Report and Order Rolf Preuss, ENP, FPEM Project Manager
  2. 2. “In this Fourth Report and Order, we adopt measures that will significantly enhance the ability of Public Safety Answering Points (PSAPs) to accurately identify the location of wireless 911 callers when the caller is indoors. We also strengthen our existing E911 location accuracy rules to improve location determination for outdoors as well as indoor calls.”

FOURTH REPORT AND ORDER Indoor Location Accuracy Requirements E911 Location Accuracy Requirements Incorporation of Roadmap and Parallel Path Dispatchable Location Horizontal Location Information Vertical Location Information Improving the delivery of Phase II location Information Latency – Time to first Location Fix Retaining E911 Phase II Accuracy Standards for Outdoors Confidence and Uncertainty (C/U) Data Provision of Live 911 Call Data
  5. 5. In the Third Further Notice, the FCC proposed establishment of an indoor location accuracy test bed for demonstrating compliance and asked about other approaches. NENA, APCO and the four national providers submitted the Roadmap agreement. The Parallel Path proposes slightly different benchmarks for non-nationwide providers. FOURTH REPORT AND ORDER Roadmap and Parallel Path
  6. 6. FOURTH REPORT AND ORDER Dispatchable Location “In the Third Further Notice, we identified the delivery by CMRS* providers to PSAPs of “dispatchable address” information as a long-term objective to improve indoor location. While we proposed indoor accuracy requirements based on x/y/z coordinate information, we noted that public safety needs would be better served if PSAPs could retrieve the caller’s building address, floor level and suite/room number” * Commercial Mobile Radio Service (CMRS)
  7. 7. Dispatchable Location FCC Definition: A location delivered to the PSAP by the CMRS provider with a 911 call that consists of the street address of the calling party, plus additional information such as suite, apartment or similar information necessary to adequately identify the location of the calling party. The street address of the calling party must be validated and, to the extent possible, corroborated against other location information prior to delivery of dispatchable location information by the CMRS provider to the PSAP.
  8. 8. Dispatchable Location What does this mean? The familiar coordinate format: 27.894127, -82.789527 Will change to: 10750 Ulmerton Rd, Bldg 1, Suite 180A, Room 201 and still be delivered in the familiar ALI format
  9. 9. Dispatchable Location Dispatchable Locations must be validated with local databases, just like they are for wireline customers. This process will eliminate location mismatches like the “registered address” on VoIP phones
  10. 10. FOURTH REPORT AND ORDER E911 Location Accuracy Requirements Horizontal Location • All CMRS providers must provide (1) dispatchable location, or (2) x/y location within 50 meters, for the following percentages of 911 calls within the following timeframes, measured from the effective date of rules adopted in this Order (“Effective Date”): – Within 2 years: 40 percent of all wireless 911 calls – Within 3 years: 50 percent of all wireless 911 calls – Within 5 years: 70 percent of all wireless 911 calls – Within 6 years: 80 percent of all wireless 911 calls Compliance will be measured on actual 911 call data.
  11. 11. FOURTH REPORT AND ORDER E911 Location Accuracy Requirements Vertical Location • All CMRS providers must also meet the following requirements for provision of vertical location information with wireless 911 calls, within the following timeframes measured from the Effective Date: – Within 3 years: All CMRS providers must make uncompensated barometric data available to PSAPs from any handset that has the capability to deliver barometric sensor data. – Within 3 years: Nationwide CMRS providers must use an independently administered and transparent test bed to develop a proposed z-axis accuracy metric, and must submit the proposed metric to the Commission for approval.
  12. 12. FOURTH REPORT AND ORDER E911 Location Accuracy Requirements Vertical Location – Within 6 years: Nationwide CMRS providers must deploy either (1) dispatchable location or (2) z-axis technology that achieves the Commission- approved z-axis metric, in each of the top 25 Cellular Market Areas (CMAs). – Within 8 years: Nationwide CMRS providers must deploy dispatchable location or z-axis technology in accordance with the above benchmarks in the top 50 Cellular Market Areas.

  16. 16. FOURTH REPORT AND ORDER Reporting and Compliance Measures • “Compliance with the above metrics will be determined by reference to quarterly live 911 call data reported by CMRS providers in six cities and their surrounding areas that have been determined to be representative of dense urban, urban, suburban, and rural areas nationally.” • “PSAPs will be entitled to obtain live call data from CMRS providers and seek Commission enforcement of these requirements” San Francisco, Chicago, Atlanta, Denver/Front Range, Philadelphia, and Manhattan Borough, New York City
  17. 17. FOURTH REPORT AND ORDER Improving the delivery of Phase II location information “In addition, we revise our regulatory framework for all 911 calls, both indoor and outdoor, as follows: – We adopt a 30-second limit on the time period allowed for a CRMS provider to generate a location fix in order for the 911 call to be counted towards compliance testing with existing Phase II location accuracy requirements that rely on outdoor testing, but we do not extend this provision to the new indoor-focused requirements adopted in this order.”
  18. 18. FOURTH REPORT AND ORDER Improving the delivery of Phase II location information – “We require that confidence and uncertainty data for the all wireless 911 calls – whether placed from indoors or outdoors – be delivered at the request of the PSAP, on a per-call basis, with a uniform confidence level of 90 percent.” “Confidence and Uncertainty (C/U) data reflects the level of confidence that a specific 911 caller is within a specified distance of the location that the carrier provides. Confidence is expressed as percentage, indicating the statistical probability that the caller is within the area defined by the “uncertainty” statistical estimate, while uncertainty is expressed as a radius in meters around the reported position. “ Third Further Notice of Proposed Rulemaking
  19. 19. FOURTH REPORT AND ORDER Improving the delivery of Phase II location information – “We require that confidence and uncertainty data for the all wireless 911 calls – whether placed from indoors or outdoors – be delivered at the request of the PSAP, on a per-call basis, with a uniform confidence level of 90 percent.”
  20. 20. FOURTH REPORT AND ORDER Improving the delivery of Phase II location information – “We require CMRS providers to provide 911 call data, including (1) the percentage of wireless 911 calls to the PSAP that include Phase II location information, and (2) per-call identification of the positioning source method or methods used to derive location coordinates and/or dispatchable location, to any requesting PSAP. Compliance with the 30-second time limit will also be measured from this data. “ – “We require all CMRS providers to collect and retain for two years 911 call tracking data for all wireless 911 calls placed on their network.”
