I don't see why you couldn't. You're just shipping serial numbers through the air at that point.

  devices have different antennas, in different places and with different orientation.

    A 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.

      What 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...

    It's accurate over 1 metre squared. I don't think the placement is too large of an issue.

      mismatched polarisation can lead to over 20db of attenuation
