Abstract
Methods of position-location determination are provided. The methods may include determining a first range for a wireless user device, using signaling from a high-confidence first ranging source. The methods may include determining a second range for the wireless user device, using signaling from a second ranging source that corresponds to a lower confidence than the high-confidence first ranging source. Moreover, the methods may include determining a position-location of the wireless user device by using a first geometric shape that is defined based on the first range. Related wireless user devices and central systems and/or central devices are also described.
