gint8 _AirpcapChannelInfo::ExtChannel

802.11n specific. Offset of the extension channel in case of 40MHz channels.

Possible values are -1, 0 +1:

  • -1 means that the extension channel should be below the control channel (e.g. Control = 5 and Extension = 1)
  • 0 means that no extension channel should be used (20MHz channels or legacy mode)
  • +1 means that the extension channel should be above the control channel (e.g. Control = 1 and Extension = 5)

In case of 802.11a/b/g channels (802.11n legacy mode), this field should be set to 0.
