I'm a pen tester by trade. I don't believe these are for wireless
   attacks. They appear to be RF signal detectors; the dB scale is to
   indicate signal strength and for locating the proximity of broadcasting
   access points or devices.

     Well that's interesting. I wondered why there were three units.

     He put it in near the stairwell door (almost next to our door RFID),
     but
     it was in full view of anyone walking to the elevators. So I don't
     think
     he was trying to hide, otherwise he would have done it from behind
     the
     stairwell door and not in plain sight. Maybe it was just bad opsec?

     Awesome. Thanks for the advice. Will look wireless intrusion
     detection.
     WPA-Enterprise too.
