pretty neat.
how robust are the fingerprints across devices i wonder and whether this has been experimented in with strong multipath effects (thereby confounding fingerprinting).
edit:
another interesting thing is that this is basically context sensitive hashing of tuples being done using ml classification techinques
- qrv3w 9y ago> how robust are the fingerprints across devices I use this system to track phones and two different computers in my home without a problem, even though I learned only one device. The RSSI values are pretty well normalized so it works well. > strong multipath effects The signals need not be normally distributed to be effective. Because this is classification it doesn't matter if the distribution of signal levels is multimodal (i.e. it is composed of multiple signal values through multiple paths), as long as the distribution of signals are different from location to location.
