Location sensing using channel fading fingerprinting

A system for providing location sensing for a receiving wireless device using channel fading fingerprinting, comprising:

• a receiving wireless device including a wireless receiver that scans wireless access points and obtains a channel fading profile from at least one of the scanned wireless access points for a present location of the receiving wireless device;
• a storage device storing a database of channel fading profiles for surveyed locations in a particular area;
• a processor that is programmed to compare the obtained channel fading profile for the present location of the receiving wireless device with the stored database of channel fading profiles;
• and
• an output device that at least one of displays and outputs an indication of an actual physical location of the receiving wireless device based on a comparison undertaken by the processor.

A non-transitory computer-readable medium storing computer-readable instructions which, when executed by a processor, cause the processor to execute a method, comprising:

• scanning wireless access points with a receiving wireless device;
• obtaining, with the receiving wireless device, a channel fading profile from at least one of the scanned wireless access points for a present location of the receiving wireless device;
• comparing the obtained channel fading profile for the present location of the receiving wireless device with a database of channel fading profiles for surveyed locations in a vicinity of the receiving wireless device to determine an actual physical location of the receiving wireless device;
• and
• outputting an indication of the actual physical location of the receiving wireless device based on the comparison.
