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)
