I deployed DWCC(https://github.com/zunder1990/Distributed-Wifi-Capability-Collector) for the first time at a large event. I was only able to get one node running, and was only able to capture packets on the following channels: 1,6,11,36,52,56,100,116. With one node running for two days and only capturing the management and control part of the wireless packets, I got 17gb of PCAPs.
Here are the results (only counting when client was talking with AP and not when client was probing broadcast):
| 2.4ghz clients | 204 | |
| 5ghz clients | 90 | Note: I was only able capture a few of the 5ghz channels |
| 802.11k clients | 110 | Provides information to discover the best available access point |
| BSS Transition/802.11r/FT | 231 | Allows for faster roaming between APs |
| QOS map | 53 | RFC 8325 tells you if the client is able to set DSCP value on packets it sends |
| receive frames from mu-mimo AP | 31 | Says if client is able to receive packets send from AP while doing mu-mimo |
| receive frames from single user beamforming AP | 51 | Says if the client is able to understand an AP trying to beamform |
| Transmission of STBC-coded frames | 28 | Space-Time Block Coding (STBC) can be used when the number of radio chains exceeds the number of spatial streams. |
| Extended Channel Switching | 80 | Provides a mechanism for an access point to notify the stations connected to it of its intention to change channels or to change channel bandwidth. |
| Orthogonal Frequency-Division Multiplexing OFDM | 126 | |
| WNM-Sleep Mode | 45 | Power save mode |
| Multiple BSSID | 13 | Client can understand when one than one BSSID is in a beacon packet from an AP |
| 802.11w | 40 | Protected Management Frames |
interworking/802.11u | 43 | Related to hotspot2.0 |
wnm notification | 59 | Related to 802.11v |
receive LDPC-encoded frames | 51 | Clients able to understand frame encoded in low-density parity-check, related to Transmission of STBC-coded frames |
Timing Measurement | 9 | 802.11mc, allows the client to tell how far it is from the AP, 3.3 nanoseconds per meter |
SSID List | 45 |
