Review of Wireless PhasesReview of Wireless PhasesIn 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

CWTA 2002

CAD and Wireless ANI/ALICAD 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

CWTA 2002

CAD and Wireless ANI/ALICAD 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

CWTA 2002

Dispatching ConsiderationsDispatching 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

CWTA 2002

Dispatching ConsiderationsDispatching 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

CWTA 2002

Dispatching ConsiderationsDispatching 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

Mapping ConsiderationsMapping 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

CWTA 2002

Mapping ConsiderationsMapping 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.
