Detailed Description

Airtime link metric calculator.

Airtime link metric is defined in 11B.10 of 802.11s Draft D3.0 as:

airtime = (O + Bt/r)* (1 + average retry counter), where:

  • o -- the PHY dependent channel access which includes frame headers, training sequences, access protocol frames, etc.
  • bt -- the test packet length in bits (8192 by default),
  • r -- the current bitrate of the packet,

Final result is expressed in units of 0.01 Time Unit = 10.24 us (as required by 802.11s draft)
