802.11 radio information

asked 2021-11-25 08:34:33 +0000

For 802.11 can anyone tell me

1) Where does wireshark get the radio information->PHY type value from?

2) How does wireshark calculate the radio information->duration for 11a and 11b? (I've tried looking at the C code but I can't get that to agree with the values I'm actually seeing in wireshark.

Thanks.
