The following is an example of a passive survey with a Proxim adapter detecting 40 MHz 802.11n and 80 MHz 802.11ac channels.
- Channel 8 is a 20 MHz channel.
- Channel 6,-1 is a 40 MHz channel (802.11n).
- Channel 161 P, 80MHz, 149-161 is an 80 MHz channel (802.11ac)
40 MHz Channels
Displayed with the primary 20 MHz channel followed by either ,1 or ,-1.
- ,1 indicates the Primary 20 MHz channel and the adjacent 20 MHz channel above, i.e. 36,1 is channel 36 (primary) and channel 40
- ,-1 indicates the Primary 20 MHz channel and the adjacent 20 MHz channel below, i.e. 40,-1 channel 40 (primary) and channel 36
80 and 160 MHz Channels
Displayed with the primary 20 MHz channel, 80MHz or 160MHz width, and channel range.
i.e. 161 P, 80MHz, 149-161
802.11ac Channel Configurations
The following table is taken from the AirMagnet Survey Pro User Guide. It shows the UNII 5 GHz bands and all applicable 20, 40, 80, and 160 MHz channel configurations.
