HOUSTON -- The Greater Harris County 911 Emergency Network, in conjunction with Cingular Wireless, has launched the second and final phase of its enhanced 911 technology in Harris and Fort Bend Counties, Texas.

"The residents of Harris and Fort Bend Counties should feel proud to know that they live in a community where the 911 Emergency Network and Cingular Wireless are committed to having the most up-to-date wireless technology for emergency situations," said John Melcher, deputy director for the Harris County 911 Emergency Network and president of the National Emergency Number Association.

Phase II provides greater Harris County public safety dispatchers with additional location information about the wireless call. Under phase I, which was deployed in Houston in May 2000, 911 systems provided the phone number of the wireless handset and the location of the cell tower carrying the call to the 911 operator. Now, dispatchers will have more precise location information about the caller.

Wireless carriers have struggled to deploy Phase II enhanced 911 service. Last year, Cingular switched technologies from a hybrid handset-network solution to a network-based solution.
