*** with the normal adapters you can capture wireless traffic but  most likely the 802.11 header will be replaced with a fake Ethernet header

AirPcap Adapter
- can capture wireless traffic on Windows environment
- on monitor mode they can capture  all 802.11  management control and data frames
-  they add a Radiotap or PPI header in front of 802.11 header wich provides channel and signal information  at the moment the packets were captures
*** if you want to capture packets on more channels you can use multiples AirPcap NICs with  AirPcap aggregate driver
