What is AirPcap?
AirPcap is an adapter that captures all or a filtered set of WLAN frames and delivers the data to the Wireshark platform. Once AirPcap is installed, Wireshark displays a special toolbar that provides direct control of the AirPcap adapter during wireless data capture. The Wireshark UI is then employed to perform network and data analysis on the packets derived from an AirPcap capture session. AirPcap is also the name of a family of products that includes AirPcap Classic, AirPcap Tx, AirPcap Ex and AirPcap Nx. This product family represents the first open, affordable, and easy-to-deploy 802.11 WLAN packet capture solutions for the Windows platform. The various members of the AirPcap family + Wireshark provide information about wireless protocols and radio signals, enabling you to capture and analyze low-level 802.11a/b/g/n wireless traffic, including control frames, management frames, and power information.
