7 CWTA 2002 Review of Wireless Phases In FCC terms: Phase I –Call back number –Tower information (Cell/Sector information - Phase.5) Phase II –Phase I data –XY Lat/Long (Latitude and Longitude) coordinates

8 CWTA 2002 CAD and Wireless ANI/ALI Standard ANI/ALI  Reformats packet  Sends packet to Answering Position  Stores packet in database Phase I Wireless  Works the same as Standard ANI/ALI

9 CWTA 2002 CAD and Wireless ANI/ALI Phase II Wireless  Similar processing to Standard and Phase I  Parses optional XML to CAD compatible string  Converts XY Lat/Long coordinates to map XY coordinates

10 CWTA 2002 Dispatching Considerations Standard ANI/ALI  Wireline 911 call –Caller’s address is displayed and verified in the Location field –Verified location is displayed on map –Phone number is displayed in Callers Number field  Wireless 911 call –Cell carrier phone number is displayed to Calltaker

11 CWTA 2002 Dispatching Considerations Phase I ANI/ALI  Wireline 911 call –Same as Standard ANI/ALI  Wireless 911 call –Address of nearest tower to the caller is entered in the Location field. The sector of the tower may be appended to the address as a comment –pAni number may display in the Additional Information or Callers Number field –Call back number may display in the Phone Number field or in Additional Information

12 CWTA 2002 Dispatching Considerations Phase II ANI/ALI  Wireline 911 call –Same as Standard ANI/ALI but with new packet processing  Wireless 911 call –Map XY coordinate is converted to Lat/Long coordinate location and displayed on CAD map –Call back number may display in the Phone Number field or in Additional Information

13 CWTA 2002 Dispatching Considerations Incoming cell 911 call

14 CWTA 2002 Dispatching Considerations

15 CWTA 2002 Dispatching Considerations

16 CWTA 2002 Dispatching Considerations

17 CWTA 2002 Mapping Considerations Map coordinate system and datum  Datums –NAD83, WGS84 in North America  CAD map and wireless XY Lat/Long may be based on different datum –Simple ANI/ALI Map based on wireless XY Lat/Long datum

18 CWTA 2002 Mapping Considerations Map Data Accuracy  Accuracy will become apparent as coordinates are obtained from external sources, such as AVL (Automatic Vehicle Location) or Wireless ANI/ALI –For network based location systems, the FCC accuracy requirement is within 100 meters 67% of the time and within 300 meters 95% of the time –For handset based location systems, the FCC accuracy requirement is within 50 meters 67% of the time and 100 meters 95% of the time.
