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):
|Note: I was only able capture a few of the 5ghz channels
|Provides information to discover the best available access point
|Allows for faster roaming between APs
|RFC 8325 tells you if the client is able to set DSCP value on packets it sends
|receive frames from mu-mimo AP
|Says if client is able to receive packets send from AP while doing mu-mimo
|receive frames from single user beamforming AP
|Says if the client is able to understand an AP trying to beamform
|Transmission of STBC-coded frames
|Space-Time Block Coding (STBC) can be used when the number of radio chains exceeds the number of spatial streams.
|Extended Channel Switching
|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
|Power save mode
|Client can understand when one than one BSSID is in a beacon packet from an AP
|Protected Management Frames
|Related to hotspot2.0
|Related to 802.11v
receive LDPC-encoded frames
|Clients able to understand frame encoded in low-density parity-check, related to Transmission of STBC-coded frames
|802.11mc, allows the client to tell how far it is from the AP, 3.3 nanoseconds per meter
