Networks are complex. Your network performance management shouldn’t be!
"Out with the old, in with the 11n USB AirPcap Nx! Whether diagnosing enterprise wireless issues or picking a channel for my Grandma’s wifi, this adapter is my favorite. It looks cool, it’s light as a feather and (since it’s integrated with WinPcap) it works seamlessly with Wireshark."
—Larry Averitt, Intel Corporation, Mobility Group
The AirPcap family is an open, affordable and easy-to-deploy wireless packet capture solution for MS Windows environments. AirPcap captures full 802.11 data, management and control frames that can be viewed in Wireshark and Cascade Pilot, providing in-depth protocol dissection and analysis capabilities. AirPcap is available in three models: AirPcap Classic, AirPcap Tx and AirPcap Nx.
|Model||AirPcap Classic||AirPcap Tx||AirPcap Nx|
|Full 802.11 Capture||Yes||Yes||Yes|
|Multi-channel Monitoring |
(requires 2+ adapters)
|External Antenna Connector||No||No||Yes|

All AirPcap adapters operate in a completely passive mode to capture all frames (data, control and management) that are transferred on a channel, not just frames that are addressed to them. When more than one BSS shares the same channel, the AirPcap adapter will capture frames from all BSSs that are sharing the channel within range of the AirPcap adapter. AirPcap adapters capture traffic on a single channel at a time; however, the channel setting can be easily changed to any valid 802.11 channel for packet capture. When used with Cascade Pilot, AirPcap can perform channel scans or lock onto multiple channels if 2 or more adapters are used.
AirPcap Tx delivers all of the functionality of AirPcap Classic and additionally supports:
AirPcap Nx delivers all of the functionality of AirPcap Classic and additionally supports:
Multiple Channel Capture: When monitoring on a single channel is not enough, multiple AirPcap adapters can be plugged into a laptop or a USB hub to provide 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 two or more 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.
Transmit Raw 802.11 Frames: AirPcap Tx and Airpcap Nx can inject raw 802.11 frames into a wireless network, making them an invaluable aid in assessing wireless security. 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.
WEP Decryption: The AirPcap driver can be configured to decrypt WEP-encrypted frames. An arbitrary number of keys can be configured in the driver at the same time, enabling it to decrypt the traffic of more than one access point simultaneously. WPA and WPA2 support is handled by Wireshark.
The AirPcap family provides superior capture performance with minimal packet loss for multi-channel capture on 802.11 networks. Integration with Wireshark and Cascade Pilot simplifies WLAN traffic analysis, visualization, drill-down, and reporting, accelerating root cause analysis for wireless environments. In addition, because AirPcap de-couples capture from analysis, it delivers added flexibility and better performance.
