Which phase of Wireless E911 provides only the estimated location of the phone?

The first phase of Wireless E911, known as Phase One, provides only the estimated location of the caller's mobile phone, specifically the location of the cell tower that is handling the call. This means that when a call is made to emergency services, the system can identify which cell tower is in use, offering a general idea of the caller's location. However, this method does not provide precise geographical coordinates; it simply indicates an area serviced by the tower, which can be quite broad.

In contrast, Phase Two is an advanced stage that provides more precise location data by delivering latitude and longitude coordinates, which greatly enhances the ability of emergency responders to find the caller quickly. Therefore, understanding the distinction between these phases is key for telecommunicators in effectively managing emergency calls and expectations regarding location accuracy.
