Phase 1 in wireless 911 refers to the delivery of which type of location data?

• A. Delivery of a wireless 911 call with tower location.
• B. Delivery of a wireless 911 call with the approximate device location.
• C. Delivery of a landline 911 call.
• D. Delivery of a wireless 911 call with no location.

Answer: (A)

Phase 1 in wireless 911 is about identifying the cell site that carried the call—the tower location. This provides an initial, approximate location to help route the call to the correct PSAP and give responders a general idea of where the caller is, based on network data rather than the phone’s exact GPS. The description that matches this is a wireless 911 call delivered with the tower location. In contrast, pinpointing the device’s exact location (which Phase II provides) would be more precise and not what Phase 1 delivers. A landline 911 call isn’t wireless, and a wireless call with no location contradicts what Phase 1 supplies.
