1. A wireless location identification method, comprising:

  • transmitting, by a wireless device, at least one sonic signal operating on at least one acoustic frequency;

    receiving, by the wireless device, at least one echo signal indicative of the at least one sonic signal being reflected by objects in a current location;

    measuring the received at least one echo signal;

    processing the at least one echo signal to extract attributes of the echo signal and generate at least one echo profile characteristic;

    comparing the at least one profile characteristic with previously-stored sonic characteristics that are correlated with pre-identified locations; and

    setting the current location as a pre-identified location correlated to the previously-stored sonic characteristics that match the at least one profile characteristic.
