TruePosition® Hybrid Location Solutions™

Every location technology has strengths and weaknesses. By combining the strengths of multiple technologies, the TruePosition® Hybrid Location Solution™ ensures high performance — regardless of the handset or environment.

TruePosition® Hybrid Location Solution™ "At-A-Glance"

  • Combines multiple location technologies to obtain higher accuracy and consistency
  • Performs in every type of environment and condition — urban, suburban, rural, indoors, in-vehicle, in-motion, and stationary
  • Can incorporate such location technologies as CID, E-CID, AOA, U-TDOA, and A-GPS
  • Delivers high customer satisfaction by optimizing performance across all subscribers’ devices and environments

While the TruePosition Hybrid Location Solution can be configured with different types of handset- and network-based location technologies — such as Cell ID (CID), Enhanced Cell ID (E-CID), Angle of Arrival (AOA), Uplink Time Difference of Arrival (U-TDOA), and Assisted Global Positioning Systems (A-GPS) — to meet the needs of the application, the optimum version in terms of accuracy, latency and yield, is to combine A-GPS with U-TDOA.

The A-GPS and U-TDOA version of the TruePosition Hybrid Location Solution can operate in two different ways:

First, A-GPS and U-TDOA can be combined in a fallback arrangement, in which the location system calls on one method when the performance of the other has deteriorated due to environmental conditions. For example, U-TDOA would be the operative method in urban areas and indoors, where A-GPS produces lesser results or fails altogether. Conversely, A-GPS would be selected in extreme rural areas where it can produce very accurate results.

Second, two location technologies such as A-GPS and U-TDOA can operate simultaneously, and the results are mathematically combined the to obtain enhanced results. The combined location calculations produce location estimates at substantially higher accuracy than A-GPS or U-TDOA alone.

Combining multiple location technologies to leverage the benefits of each, the TruePosition Hybrid Location Solution can gain higher accuracy and consistency than any other single location technology.
