E-OTD (Enhanced Observed Time Difference) standard hybrid method for GSM conceptually, method is similar to U-TDOA.
Because the TruePosition LMU-Universal is so sensitive, TruePosition U-TDOA is able to work indoors and in dense urban environments with tall buildings where GPS performance is limited.
Because the solution is highly sensitive, TruePosition U-TDOA is able to work indoors and in dense urban environments with tall buildings where GPS performance is limited.
The Location System combines the widest variety of positioning technologies, including network and handset-based location solutions such as U-TDOA, Cell ID, Enhanced Cell ID, A-GPS and future hybrid solutions.
TruePosition U-TDOA is a location technology that can accurately and reliably locate any mobile phone in any environment, where other location technologies such as A-GPS cannot.
TruePosition U-TDOA quickly and accurately locates any phone in any environment using Location Measurement Units (LMUs) installed at the cell towers to calculate a phone's position.
This decision secures the fact that TruePosition has vital intellectual property surrounding U-TDOA and further establishes TruePosition as the global leader in mission-critical wireless location solutions.

TruePosition's U-TDOA network-based location technology meets the strict Phase II performance requirements developed by the Federal Communications Commission (FCC) as part of their E9-1-1 Mandate.
Of the four technologies tested, U-TDOA was the only one to have a 100 percent yield in both urban and suburban performance testing, with every test call generating corresponding location information.
TruePosition's U-TDOA technology has been engineered to provide the same highly accurate positioning for LTE 4G networks as it has for the prior generations of network technology.
