1. A method at a detector for preparing RF data for use in determining a location of a wireless mobile device in a wireless communications environment, comprising:
receiving signals from one or more receive channels that include parameters for a localization signal of the wireless mobile device, the parameters being associated with known in advance signals within the signals;
receiving metadata related to the signals;
detecting the known in advance signals from each receive channel among the one or more receive channels based on the parameters of the localization signal;
buffering a plurality of samples in a digital format extracted from the known in advance signals;
extracting data necessary for determining the location from the plurality of samples; and
sending the extracted data, the parameters of the localization signal, and the metadata to a locate server physically remote from the detector for determination of the location.
