8 Accuracy in the Past Previous FCC rules relied on carrier drive testing of networks to characterize location accuracy performance, not on live-call data. All accuracy performance data was carrier proprietary, and not subject to inspection by public safety entities. Carriers could elect one of two location-accuracy compliance regimes: Network-Based carriers must locate 67% of all test calls within 150m and 90% of all test calls within 300m of ground-truth location. Handset-Based carriers must locate 67% of all test calls within 50m and 90% of all test calls within 150m of ground-truth location. 8

9 Roadmap & Parallel Path Roadmap: NENA: The Association APCO International AT&T Sprint T-Mobile Verizon Parallel Path: Competitive Carriers Association (With input from NENA & APCO) 9

10 Roadmap Principles Change the goal from ʹ N Latitude / ʹ W Longitude to 1700 Diagonal Road, Suite 500. Characterize the performance of location technologies in an open and transparent testbed that accurately represents real-world conditions. Base future compliance assessment on data from live calls. Minimize any coverage gap for Dispatchable Location technologies by requiring improvements in Latitude/Longitude/Altitude technologies, and unifying the compliance regime. Provide clear metrics, FCC-enforceable terms, and fallback provisions to ensure carrier adherence, while accommodating legitimate unknowns (e.g., the time required to complete standards work). 10

11 What Isn t Changing PSAPs will still receive a latitude/longitude estimate with most calls, including confidence and uncertainty data, if equipped to handle it. Address information for calls with Dispatchable Location data will be delivered in the familiar ALI formats that PSAPs use today. Dispatchable Locations must be validated with local databases (MSAG or LVF), just like they are for wireline customers. Carrier networks will continue to intelligently choose from, and deliver, the best-available location information. 11

12 Dispatchable Location Defined 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 Diagonal Road } Street Address Suite 500 } Additional Info Alexandria, VA 22314} Jurisdiction 12

13 Dispatchable Location Defined The street address of the calling party must be validated Beacon Addresses Validated Addresses Only National Emergency Address Database This definition ensures that PSAPs will have actionable, MSAG/LVF-valid address. Beacon Entry Time MAC/UUID (From Phone) evolved Serving Mobile Location Center (esmlc) Call Time MSAG (Valid/Invalid) Automatic Location Identification (ALI) PSAP Call Taking Display 13

14 Dispatchable Location Defined and, to the extent possible, corroborated against other location information prior to delivery of dispatchable location information by the CMRS provider to the PSAP. This definition ensures that a location mismatch (a-la VoIP registered address ) has not occurred. 14

19 Dispatchable Location Timeline 2/15 Working Groups Established 8/15 Dispatchable Location Demo 11/15-5/16 Standards Work Completed (Range) 5/16-11/16 New WHP Products Support DL 11/17 National Emergency Address Database Online 1/15 4/15 7/15 10/15 1/16 4/16 7/16 10/16 1/17 4/17 7/17 10/17 11/17/ /17/ months: Carriers, NENA, and APCO will jointly design and implement a National Emergency Address Database that correlates the physical MAC address of WiFi and UUID of BluetoothLE beacons with Dispatchable Locations. 19

20 Dispatchable Location Tech WiFi MAC Address 04:0A:1A:66:BF:F1 The Media Access Control Address is a hard-coded, unique identifier for each wireless system. Bluetooth LE UUID 123e4567-e89b-12d3-a The Universally Unique Identifier serves a similar function for Bluetooth Low Energy devices. 20

21 Dispatchable Location Roll-Out Carriers will introduce support for Dispatchable Location technology in the following fractions of new, VoLTE handsets within the specified times, following the completion of standards: 25% in months 50% in months 100% in months Carriers will introduce support for Dispatchable Location technology network-wide within 24 months after standards completion. Carriers will provide end-to-end support for Dispatchable Location technology, including final delivery to ALI providers within 48 months of the date of the agreement. 21

22 Location Accuracy Test Bed Permanent test-bed for DL & X/Y/Z, established within 12 months. Objective, Transparent, Open, & Public-Safety Inclusive Representative of all morphologies (Dense Urban, Urban, Suburban, Rural) Three purposes: Remove all doubt about the art of the possible. Characterize the performance of X/Y/Z technologies to determine which qualify, and to what extent, as Higher Accuracy. Provide compliant fractions to assess live call data. 22

23 Lat/Lon Tech (Definitions) OTDOA stands for Observed Time-Difference of Arrival. OTDOA relies on handset measurements of the difference between arrival times of precisely-synchronized transmissions from nearby cell towers. These time differences describe hyperbolic lines-of-position. The point where two or more of these lines intersect is the caller s location. 23

24 Lat/Lon Tech A-GNSS stands for Assisted- Global Navigation Satellite System. It relies on handset measurements of ranging signals broadcast from two or more constellations of satellites. These ranges define spherical surfaces of position. The Assisted aspect means that the handset receives data from the carrier network to greatly speed-up the search for satellites and the calculation of a position estimate. 24

25 Lat/Lon Tech Currently, two constellations are fully operative: the U.S. NavStar constellation (better known as GPS ) and the Russian GloNaSS constellation. Two more systems, the European GALILEO and Chinese BeiDou, are in the early stages of deployment, but should be complete within a decade. All foreign systems will require a comprehensive security review before being used for

26 Improvements to Lat/Lon Tech Carriers will deploy both OTDOA and A-GNSS throughout their networks, and will support hybrid measurements using both systems. The following fractions of new VoLTE handsets will support both systems on specified timeframes, measured from the date of the agreement: 50% at 24 months 75% at 36 months 100% at 48 months Carriers will test Lat/Lon estimates based on crowd-sourced WiFi and Bluetooth measurements in approximately 36 months. 26

27 Improvements to Lat/Lon Tech Carriers will standardize the confidence level at which uncertainty values are calculated. All wireless calls will soon appear with 90% confidence levels. Position determining system is 95% confident that true position falls within this circle Position determining system is 63% confident that true position falls within this circle reported position true position u confidence=63% This means that search rings (uncertainty) may, on average, be larger than previously seen for at least some carriers. It also means that the caller will be more likely to be found inside the search circle. u confidence=95% Uncertainty u is proportional to the confidence factor c. o o The smaller the confidence percentage, the shorter the uncertainty distance. The larger the confidence percentage, the longer the uncertainty distance. 27

28 Performance Metrics Carriers will report on live call data in six regions in and surrounding major cities, chosen to be representative of the Dense Urban / Urban / Suburban / Rural morphologies evaluated by CSRIC. 28

29 Performance Measurement Reports will indicate the positioning source method for each call (e.g., Dispatchable Location, A-GPS, AFLT, RTT, Cell ID, A-GNSS, OTDOA, and hybrids of such). Data will be aggregated monthly and reported to NENA, APCO, and the FCC quarterly. Outside the measurement regions, carriers must make available to requesting PSAPs positioning source method data so that local authorities can monitor carrier performance Authorities must work with carriers to resolve performance issues before seeking FCC enforcement actions. 29

30 Performance Metrics To the extent that a given positioning source provides either a Dispatchable Location or an accuracy of 50m or better, carriers will receive credit for that fraction of fixes. For example, if OTDOA produces 50m fixes (at the 90% confidence level) 10% of the time, and 50% of a carrier s fixes came from OTDOA, the carrier would receive credit for 10% * 50% = 5% of compliant fixes. DATA TABLE CREATED RANDOMLY: NOT REPRESENTATIVE!!! Technology % of tests 50m % of live calls % contribution to compliant fraction Dispatchable Location 100% 5% 5% OTDOA/A-GNSS 60% 75% 45% A-GNSS Only 55% 15% 8% WiFi 45% 5% 2% Compliant Fraction: 60% 30

31 Performance Metrics Carriers will provide at least the following fractions of calls with either a Dispatchable Location or from a 50m-or-better technology on the specified timeframes: 40% of all wireless calls within two years 50% of all wireless calls within three years 70% of all wireless calls within five years 80% of all wireless calls within six years Carriers must certify that their networks perform similarly outside the 6 test regions. Further, PSAPs can use location source codes to verify that the compliance fractions are being met in their jurisdiction. Small or rural carriers have extra time, based on VoLTE deployment. 31

32 Vertical Location Information Carriers, NENA, and APCO will conduct a study within 6 months to evaluate options for using raw or uncompensated barometric pressure readings in the field. Carriers will promote the development of standards for the delivery of uncompensated barometry (e.g., kpa ) to PSAPs within 18 months. 32

33 Vertical Location Information Carriers will work with NENA and APCO to test the use of compensated altimetry (i.e., 75m above Mean Sea Level ). Within 36 months, carriers, NENA, and APCO must develop a Z-Axis metric, based on testbed data, for submission to the FCC. 33

34 Vertical Location Information Within 6 years, carriers must, for each of the top 25 Cellular Market Areas (by population) deploy either: 1 Dispatchable Location reference point within that market (WiFi/BluetoothLE beacon) for every 4 residents; or Employ Z-Axis technology covering at least 80% of the population of that CMA. 34

35 Formal Evaluation NENA and APCO will evaluate carrier performance and adherence to timelines throughout the term of the agreement. Reasonable variations in some time periods (e.g., standards development cycles) are to be expected, but will be closely monitored. At the 36-month mark, a major assessment will determine whether the development and deployment of Dispatchable Location technology is on track. If so, work will continue apace. If not, carriers have committed to supplement dispatchable locations with specific Lat/Lon and Altitude technologies within aggressive timeframes. 35
