5. Working Group 3, “Leveraging LBS” report - Work Completed  Final report covering:  Location Technologies now used only for LBS, but which may be adaptable for Indoor E9-1-1  Emerging Location Technologies that could possibly be used for Indoor E9-1-1  For each of these technologies, assessment of:  Accuracy and Time-to-First-Fix (TTFF)  Location yield  Network Impact  Handset Impact  Standards Implications  Database creation and maintenance issues 5

6. Working Group 3, “Leveraging LBS” report - Work Completed (cont.)  The following location technologies were analyzed:  WiFi-based Location  Metropolitan beacon  O-TDOA for LTE  RF Fingerprinting  Low-earth Orbit Satellite-based Positioning  Distributed Antenna Systems (DAS) Positioning  Assisted-GNSS  Hybrid Positioning using Multiple Location and Inertial Navigation Sensors  Role of the Test Bed  Only technologies that participated in the test bed had detailed parametric accuracy, yield, and TTFF claims shown in the Leveraging LBS report 6

7. Working Group 3, “Leveraging LBS” report – Summary & Next Steps  The diversity of location technologies reviewed in this report confirms that continual advances are being made in the field. Additionally, all the technologies discussed lend themselves to hybridization, i.e., the blending of measurements from multiple technologies to increase yield, and possibly accuracy. However, very few of these location technologies are currently available for E-9-1-1 use indoors. Three location technologies participated in the Indoor Test Bed. Based on the results, the workgroup believes that good progress is being made in addressing the indoor location challenge; however, significantly more work needs to be done, including characterization of additional technologies in a Phase 2 test bed.  We recommend establishment of subsequent Test Bed trials to evaluate future technologies, such as WiFi, GLONASS, U-TDOA, and O-TDOA for LTE 7

8.
