Cingular Switches to U-TDOA for E-911 Positioning
Dec 17, 2002, 12:25 AM by (staff)
Cingular has decided to switch technologies for meeting the FCC's E-911 mandate for locating 911 callers. Cingular has told the FCC that after completing successful field trials involving TruePosition's network-based U-TDOA technology, it was moving away from E-OTD, which so far has failed accuracy tests, resulting in delays and financial penalties. Cingular in October suspended shipments of E-OTD gear and began testing TruePosition's solution.
