Abstract
Techniques for determining a relative Time Calibration (dTcal) value for a mobile device model are disclosed. An example of an apparatus according to the disclosure includes a memory, a receiver configured to receive measurements and a mobile device model information from mobile devices disposed in geographic areas, a processor configured to determine a baseline mobile device model and other mobile devices models based on the measurements, calculate a baseline measurement value based on the measurement values that correspond to the baseline mobile device model, determine difference values based on the baseline measurement value and the other mobile device model measurement values, determine a model specific dTcal value based on the difference values for at least one of the other mobile device models, and store the model specific dTcal value in the memory.
