The wireless carrier had been hinting since October that it was considering a change in technology due to dissatisfaction with its current choice. This switch could potentially lead to fines from the Federal Communications Commission (FCC). Cingular is planning to request an extension from the FCC to meet Enhanced 911 (E911) requirements, which they have previously been fined for missing deadlines.

By 2004, all wireless carriers are required to implement a service that enables emergency call centers to locate individuals dialing 911 from cell phones. With over half of all 911 calls now originating from mobile devices, the need for E911 services has become increasingly critical for saving lives in emergency situations.

Carriers such as AT&T Wireless, Cingular, and T-Mobile initially opted for Enhanced Observed Time Difference (EOTD) technology, utilizing multiple cellular base stations to determine a cell phone’s location based on signal arrival times. While effective in urban areas with dense antenna coverage, EOTD’s accuracy diminishes in rural regions where base stations are further apart.

Recognizing these limitations, Cingular is exploring Uplink Time Difference of Arrival (U-TDOA) technology as a replacement. Developed by TruePosition, U-TDOA calculates a phone’s position by measuring call arrival times at “location measuring units” within network base stations. Unlike EOTD requiring specialized handsets and network software modifications, implementing U-TDOA only necessitates software integration into existing networks.

Cingular conducted successful tests of the U-TDOA system in Wilmington, Del., surpassing FCC accuracy standards in certain instances according to recent filings. Whether other carriers like AT&T Wireless and T-Mobile will also consider adopting this technology remains uncertain.
