2 Will you have to answer this question?

3 9-1-1 Fast Facts From NENA.ORG website based on most recent FCC quarterly filing Estimated 200 million 911 calls made annually with 1/3 being wireless. Of the 6,173 Primary and Secondary PSAPs –77.0% have some Phase 1 –50.9% have some Phase 2 Of the 3,135 US Counties –68.6% have some Phase 1 –40.7% have some Phase 2 Approximately 82% of the US Population have some Phase 1 Approximately 64% of the US Population have some Phase 2

4 W ireless 911 Legislative Background

5 FCC Order The Order provides specific rules regarding routing & delivery of wireless calls –3 Phases: Phase 0 - All wireless calls will route to a destination that can respond to an emergency. A cell site will not be placed “in service” unless routing has been properly established. Essentially this is “Call Forwarding” and is voice only. Phase I - Delivery of call back number (ANI) and cell site location information (ALI) to PSAP. PSAP must make a formal request for the service. PSAP must be capable of receiving and utilizing the information. The wireless company must comply within 6 months*. Phase II - Delivery of call back number (ANI) and estimated location of the handset (ALI) must be supplied to the PSAP (may require re-bid). PSAP must make a formal request for the service and be ready to receive the data. The wireless company must comply within 6 months or in a timeline determined by the FCC*. Location criteria is subject to type of solution: Handset Solution ► 50m for 67% of calls, 150m for 95% of calls (Verizon Wireless, Sprint/Nextel, Alltel, and…) Network Solution ► 100m for 67% of calls, 300m for 95% of calls (T-Mobile, Cingular Wireless and...)

6 City of Richardson Order The City of Richardson Order was established by the FCC (effective November 2001). It describes the prerequisite conditions for Phase I & II deployment; what is needed to be considered a “valid” request. Additional clarification, including timelines, was made in the Richardson Reconsideration Order (effective Feb 2003). The Richardson Reconsideration Order outlines the FCC's efforts to define when a PSAP is ready to "receive and utilize" the data elements of wireless E9-1-1 services, and the responsibilities placed on wireless carriers in ascertaining and documenting a PSAP's readiness.

7 City of Richardson Order (continued) Pursuant to the Order, the PSAP may demonstrate that the Phase I &/or II request is valid by providing the wireless company with documentation demonstrating all of the following: a) A funding mechanism exists for recovering the PSAP’s cost of facilities and equipment necessary to receive and utilize the E9-1-1 data elements (e.g., citation to or copy of the relevant funding legislation); b) The PSAP has ordered the equipment necessary to fulfill its Phase II obligations, and that such equipment is already installed or is scheduled to be installed and operable before the end of the six month period (e.g. list of facilities and copies of relevant purchase orders, with purchase orders demonstrating commitment to vendor performance within six month period or other substantiation of vendor commitment to perform within six month period); and….

8 City of Richardson Order (continued) c) The PSAP has made a timely request to the proper LEC for the facilities and equipment necessary to receive and utilize the Phase II data elements (e.g., letter of request and any other pertinent correspondences between the PSAP and LEC). Mutual Consent Deadlines - In the Richardson Reconsideration Order, the FCC explicitly provides that a PSAP and wireless carrier(s) can establish their own deadlines for wireless E9-1-1 Phase I & II implementation by mutual consent.

9 Regulatory/Legal Considerations Non-Disclosure Agreements to protect data exchange Phase I & II Service Agreements to define roles & responsibilities Some Wireless Carriers will request the following Agreements:

10 Regulatory & Legal

25 Two Different Phase II NCAS Solutions  Handset Solution ~ Used by Alltel, Sprint/Nextel, Verizon Wireless, and ….  Network Solution ~ Used by T-Mobile, Cingular, and…..

26  Position Determination Entity (PDE) – The PDE functions to calculate a latitude and longitude to represent the location of the mobile handset. In order to accurately locate a handset, the PDE requires a variety of prior knowledge of the wireless network.  Base Station Almanac (BSA) – Contains all of the cell site information on per MSC basis. Data is collected from local RF Engineering group and has data layers added after Survey and Calibration of a cell site is completed.  Assisted GPS / Advanced Forward Link Trilateration (AGPS/AFLT) – Must be GPS capable handsets AGPS/AFLT will not work on legacy CDMA mobiles. E9-1-1 Phase II Handset Solution Definitions

27  AGPS is a handset modification incorporating additional hardware and software, which allows the handset to utilize signals from GPS satellites for location information.  AGPS handsets require hardware such as a GPS-supported chipset, new radio, antenna, and other minor hardware to exist within the handset to make it capable of receiving and sending GPS information to and from the network.  This location method is called “Assisted” because the network provides the mobile with information on which satellites to listen to, thus reducing the time it takes to obtain location information and calculate the actual position of the handset.

31 A-GPS: Strength & Weaknesses System accuracy has averaged 5 – 10 m Call setup / TTFF is less than 30 seconds Multiple rebids allow for continuous tracking Implementation proven successful with multiple ILECs Location detection in building or other structures is not available System accuracy in terrain challenged areas varies within 50m.

32 E9-1-1 Phase II Network Solution T-Mobile and Cingular Wireless are implementing a solution known as TDOA (Time Difference of Arrival) in their GSM Networks. True Position is the vendor providing this solution. TDOA is an overlay network technology that uses a base station timing source (GPS Antenna). The TDOA equipment measures the time delay from multiple sensors for the caller. The TDOA Network solution does not require subscribers upgrade their handset.


34 Phase I & II Testing Phase I & II testing, in coordination with the PSAP, will ensure the following: Emergency calls are routed to the appropriate PSAPEmergency calls are routed to the appropriate PSAP Phase I information displays at the PSAP (cell/sector address)Phase I information displays at the PSAP (cell/sector address) Phase II data (X, Y coordinates) display at the PSAP properlyPhase II data (X, Y coordinates) display at the PSAP properly The caller’s “call back” number displays at the PSAPThe caller’s “call back” number displays at the PSAP PSAP re-bid displays correctlyPSAP re-bid displays correctly Once the testing completes, the PSAP will be considered “live” with Phase I & II service. Phase II data does not include information such as altitude, speed, or direction of travel. Phase II data may or may not include confidence or uncertainty factors depending on PSAP equipment and LEC capability.

35 Carrier Costs Usually Treated as Proprietary & Confidential Cost Appear As: Non-Recurring Costs (NRC) Monthly Recurring Costs (MRC) Recoverable Costs Include: GMLC / MPC Charges Local Exchange Carrier Charges Administrative Costs Costs Based on: Subscriber Count Cell Site Count Carrier is Self Recovering (Line Item on Subscriber’s Statement)
