1. A method for operating a radio-enabled tracking and locating system, the method comprising:
scanning for and capturing, by a radiotag, an ensemble of Bluetooth (BT) radio signals from a BT spread spectrum signal topology in radio proximity thereto, said capture defining a digital radio snapshot, wherein the radiotag includes a processor, a BT radio modem, a unique radio unit identifier, a community identifier, a cellular radio modem, and a flash memory unit configured to store one or more digital radio snapshots of intercepted BT radio signals each with a timestamp;
predicting, by the radiotag, a current location of the radiotag in near real time by matching the one or more digital radio snapshots of intercepted BT radio signals with a snapshot from a library of digital radio snapshots stored in the library from a past time, each snapshot in the library from a past time defining a reference snapshot assignable to a known location; and
controlling, by the radiotag, a CALL HOME event in response to determining that the current location meets one or more criteria defined by a user in a user profile, wherein controlling the CALL HOME event includes initiating a cellular Connection Request to a designated IP Address via the cellular radio modem.
