AirPcap

The AirPcap family is an open, affordable and easy to deploy wireless packet capture solution for Windows. AirPcap captures full 802.11 data, management, and control frames that can be viewed in Wireshark and Riverbed Cascade Pilot, providing indepth protocol dissection and analysis.

Transmit Raw 802.11 Frames on Your Network AirPcap Tx and Airpcap Nx have the ability to inject raw 802.11 frames into your wireless network which makes them an invaluable aid in assessing the security of your wireless network. AirPcap Tx and AirPcap Nx can inject any kind of frame, including control, management, and data frames. These frames can be transmitted at any allowable rate depending upon your adapter.

All AirPcap adapters can operate in a completely passive mode. In this mode, the AirPcap adapter will capture all of the frames that are transferred on a channel, not just frames that are addressed to it. This includes data frames, control frames and management frames. When more than one BSS shares the same channel, the AirPcap adapter will capture the data, control, and management frames from all of the BSSs that are sharing the channel within range of the AirPcap adapter. AirPcap adapters capture traffic on a single channel at a time. The channel setting for the AirPcap adapter can be changed using the AirPcap Control Panel, or from the "Advanced Wireless Settings" dialog in Wireshark. Depending on the capabilities of a specific AirPcap adapter

When monitoring on a single channel is not enough, multiple AirPcap adapters can be plugged into your laptop or a USB hub and provide industry-leading capability for simultaneous multi-channel capture and traffic aggregation. The AirPcap driver provides support for this operation through Multi-Channel Aggregator technology that exports capture streams from multiple AirPcap adapters as a single capture stream. The Multi-Channel Aggregator consists of a virtual interface that can be used from Wireshark or any other AirPcap-based application. Using this interface, the application will receive the traffic from all installed AirPcap adapters, as if it was coming from a single device. The Multi-Channel Aggregator can be configured like any AirPcap device, and therefore can have its own decryption, FCS checking, and packet filtering settings.
