Why does using a cell phone to call 9-1-1 complicate the process?

Explanation:

cell-tower antenna the phone is using. The call has been routed to the PSAP nearest to that tower. As of 2006, 83.6 percent of PSAPs have implemented all or part of Phase I. Phase I technology can only locate a cell phone within a 30-mile to 6-mile radius.

Phase II: The call-taker can see the cell-phone number and the location of caller to an accuracy of 50 to 300 meters depending the type of location system being used by the wireless provider. The call has been routed to the PSAP nearest to that location or nearest to the cell antenna in use, depending on the particulars of the system. As of 2006, 65.2 percent of PSAPs have implemented all or part of Phase II.
