The AirPcap Product Family is a complete range of 802.11 USB-Based WLAN packet capture solutions for Windows
The AirPcap family is the first open, affordable and easy-to-deploy packet capture solution for Windows. AirPcap captures full 802.11 data, management, and control frames that can be viewed in Wireshark providing in-depth protocol dissection and analysis capabilities. The feature matrix below gives a high-level overview of each adapter in the AirPcap Product Family. More detailed information regarding each can be found on the relevant corresponding product pages.

How AirPcap Adapters Operate
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, it can be set to any valid 802.11 channel for packet capture.
The AirPcap software can be configured to decrypt WEP-encrypted frames. An arbitrary number of keys can be configured in the driver at the same time, so that the driver can decrypt the traffic of more than one access point simultaneously. WPA and WPA2 support is handled by Wireshark.
Multiple Channel Capture
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 CACE 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.
Designed to Meet All of Your 802.11 Diagnostic Needs, Offering a Host of Unrivaled Features
AirPcap Nx continues the tradition of the AirPcap Family by providing a USB-based and easy-to-deploy packet capture and injection solution for the Windows platform. This unique dual-band offering supports packet capture and injection for 802.11n, 802.11a/b/g legacy modes, and the 4.9 GHz US Public safety channels, all with full Wireshark® integration. It also features 2 x 2 MIMO with two internal antennas. In addition to the internal antennas, AirPcap Nx has two integrated MC-Card connectors for optional external antennas to enhance performance in the most demanding environments.
802.11n is an exciting new technology, but it introduces many potential problems due to its complexity and the need for compatibility with existing 802.11b, a, and g networks. With AirPcap Nx you get complete visibility into your 802.11a/b/g/n wireless networks. This includes general 802.11 information such as data, management, and control frames along with 802.11n-specific information such as HT information, aggregate MPDUs, and aggregate MSDUs.
AirPcap Nx replaces the AirPcap N 32bit CardBus adapter, providing advanced technology and additional capabilities that include:
- 802.11n traffic capture on 20MHz and 40 MHz channels
- 802.11a, b, g packet capture on 20MHz channels
- 802.11a, b, g, and n packet injection at all rates
- Detailed decoding of control, management, and data frames in Wireshark, including A-MSDUs, A-MPDUs, and HT information
- Per-packet radio information
- Microsecond timestamp resolution
- Two internal antennas and two integrated MC-Card connectors for optional external antennas
- Support for 2x2 MIMO
- Monitor multiple channels simultaneously and capture into a single, merged trace file using multiple AirPcap Nx adapters and CACE's exclusive multi-channel aggregation technology
- Full integration with Wireshark and CACE PilotTM for complete WLAN traffic analysis, visualization, drill-down, and reporting
- USB host interface provides for portability and flexibility in deployment
- AirPcap and WinPcap APIs are provided for creation or extension of your own 802.11n testing and diagnostic tools
AirPcap Nx 3-Pack
AirPcap Nx 3-Pack provides industry-leading capability for simultaneous multi-channel capture and traffic aggregation. The 3-Pack let's you simultaneously monitor 3 different channels and allows you to capture each channel into separate trace file. Additionally, AirPcap Nx software provides a merge of the multi channel capture into a single trace file. These features are fully integrated with Wireshark and CACE Pilot thereby enhancing your troubleshooting effectiveness in multi channel environments. Naturally, the more AirPcap adapters you have, the more channels you will be able to capture simultaneously.
