Once finger printing has been done can that info be shared with other cell phones?

- Sanddancer 10y agoI don't see why you couldn't. You're just shipping serial numbers through the air at that point.
- rasz_pl 10y agodevices have different antennas, in different places and with different orientation.
- fabulist 10y agoA wifi antenna should always be vertically oriented because radio waves are polarized, and if you aren't in line with the polarization you'll lose gain.
- rasz_pl 10y agoWhat is the polarity of ipad antenna on your lap? :) Then you have multipath (reflections). This is why wifi cards had diversity switch and two antennas even before MIMO, and with 11n gained spatial diversity and beamforming. random google result: http://www.theruckusroom.net/2011/06/a-polarizing-problem.html http://www.theruckusroom.net/2011/06/a-polarizing-problem.ht...
- timlyo 10y agoIt's accurate over 1 metre squared. I don't think the placement is too large of an issue.
- rasz_pl 10y agomismatched polarisation can lead to over 20db of attenuation
- iamflimflam1 10y agoYes according to the FAQ: "The WiFi fingerprints are also the same across all devices so that learning using one device is guaranteed to work across all devices." https://github.com/schollz/find/blob/master/FAQ.md#doesnt-this-already-exist https://github.com/schollz/find/blob/master/FAQ.md#doesnt-th...
- qrv3w 10y agoYes you can! Just share the "Group" name that you used for the fingerprinting.
