SONIC-ASSISTED LOCALIZATION OF WIRELESS DEVICES
First Claim
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.

Abstract
Wireless location identification systems, methods, and devices include a wireless device configured to transmit at least one sonic signal operating on at least one acoustic frequency and to receive at least one echo signal indicative of the at least one sonic signal being reflected by objects in a current location, an audio module configured to measure the received at least one echo signal and process the at least one echo signal to extract attributes of the echo signal and generate at least one echo profile characteristic; and logic configured to compare the at least one profile characteristic with previously-stored sonic characteristics that are correlated with pre-identified locations. The current location is then identified as a pre-identified location correlated to the previously-stored sonic characteristics that match the at least one profile characteristic.
