Comment(by carrano):

 Do we know what Access Point models were used in the PyCON conference? We
 should investigate WDS related issues.

 On beacons:
 Please take a look at the attached graph.
 - The black line accounts for the total traffic in bytes per second as
 captured in 1cc (Kim's office)
 - The green line is the traffic generated by beacons alone.
 - The blue line is traffic generated by beacons *coming from XOs*

 The graph and the trace files indicate that the major source of beacons
 are Access Points.

 And the trace file indicates that the rate of captured beacons were
 inferior than 20 beacons per second.

 So, why we do not have a flood of beacons? (There is about 15 XOs in Kim's
 office alone)

 Mihalis Bletsas just explained that the XOs backoff when they hear
 beacons.
