Analytic and tracking systems and methods are described that use over-the-air identifiers (OTAIs) of mobile devices for tracking, dispatch, identification, etc. In particular, the analytic and tracking systems and methods can include various OTAI sensors that are communicatively coupled to a server and with one another. The OTAI sensors are configured to identify proximate mobile devices concurrent with at least one additional piece of information. The analytic and tracking systems and methods can process identified mobile devices and the additional pieces of information for a plurality of applications.
