9-1-1 Fast FactsFrom NENA.ORG website based on most recent FCC quarterly filing

Estimated 200 million 911 calls made annually with 1/3being wireless.

Of the 6,173 Primary and Secondary PSAPs

77.0% have some Phase 1


Of the 3,135 US Counties



Approximately 82% of the US Population have somePhase 1

Background


5/35

FCC Order 94-102The Order provides specific rules regarding routing & delivery of wireless 9-1-1 calls

3 Phases:

Phase 0- All wireless 9-1-1 calls will route to a destination that can respondto an emergency. A cell site will not be placed in service unless 9-1-1routing has been properly established. Essentially this is Call Forwardingand is voice only.

Phase I- Delivery of call back number (ANI) and cell site locationinformation (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 I I- Delivery of call back number (ANI) and estimated location of thehandset (ALI) must be supplied to the PSAP (may require re-bid). PSAPmust 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 (VerizonWireless, Sprint/Nextel, Alltel, and)

Network Solution 100m for 67% of calls, 300m for 95% of calls (T-Mobile,Cingular Wireless and...)

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 madein 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 wirelessE9-1-1 services, and the responsibilities placed on

wireless carriers in ascertaining and documenting a

PSAP's readiness.


7/35

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 wirelesscompany with documentation demonstrating all of thefollowing:

a) A funding mechanism exists for recovering the PSAPs cost of

facilities and equipment necessary to receive and utilize the E9-1-1data elements (e.g., citation to or copy of the relevant fundinglegislation);

b) The PSAP has ordered the equipment necessary to fulfill itsPhase II obligations, and that such equipment is already installed or

is scheduled to be installed and operable before the end of the sixmonth period (e.g. list of facilities and copies of relevant purchaseorders, with purchase orders demonstrating commitment to vendor

performance within six month period or other substantiation ofvendor commitment to perform within six month period); and.


8/35

City of Richardson Order (continued)

c) The PSAP has made a timely request to the properLEC 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.

T-Mobile, Cingular, and..


26/35

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 cellsite 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 I IHandsetSolution Defini tions

27/35

AGPS is a handset modification incorporating additionalhardware 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 existwithin 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.

E9-1-1 Phase I INetworkSolution

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.

Phase I INetworkSolution Diagram

In order to implement U-TDOA, Uplink -Time Difference of Arrival, several new elements aredeployed in the GSM network, an SCP, Service Control Point, U-TDOA PDE, PositioningDetermining Equipment, and, LMU, Location Measuring Unit. The PDE performs the locationcalculations by gathering information from the LMU's which are co-located with cell towerequipment. The SCP acts as the interface between the wireless carrier's network and thePSAP. The MSC triggers the request for positional information to the SCP and the SCPsubsequently presents the calculated lat/long to the PSAP.


34/35

Phase I & I I TestingPhase I & II testing, in coordination with the PSAP, will ensure the following:

Emergency calls are routed to the appropriate PSAP

Phase I information displays at the PSAP (cell/sector address)

Phase II data (X, Y coordinates) display at the PSAP properly

The callers call back number displays at the PSAP

PSAP re-bid displays correctly

Once the testing completes, the PSAP will be considered livewith 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 uncertaintyfactors depending on PSAP equipment and LEC capability.
