Aruba: Removing VBR Dependency on Probe Requests

sombody in idea what Aruba means with "Removing VBR Dependency on Probe Requests"?

[...] Client Match uses AM data feeds to gain more continuous, comprehensive client RSSI feeds [...]

Frames used for this:

  • Block ACK
  • Management frames
  • NULL data frames
  • Data frames with rates no higher than 36Mbps
  • Control frames

How should I receive frames from a client that is not on my channel? Is this just for updating the RSSI for my associated client? So I can not create a hearing map?
