AirPcap is the first open, affordable and easy to deploy WLAN (802.11b/g) packet capture solution for the Windows platform. AirPcap comes as a USB 2.0 adapter, and it’s been fully integrated with WinPcap and Wireshark: it enables you to capture and analyze 802.11b/g wireless traffic, including control frames, management frames and power information, using Wireshark on your Windows laptop.
AirPcap Key Features
- Full integration with Wireshark and Cascade Pilot for complete WLAN traffic analysis, visualization, drill-down, and reporting
- Monitor Multiple Channels Quickly and Conveniently with AirPcap and Wireshark
- AirPcap 3-pack for Multi-Channel, Aggregated Analysis
- Portable and Versatile
- Easy to Setup and Easy to Use
- Professional Performance
Building or securing wireless networks can be a challenge when your tools don’t understand radio waves. AirPcap Classic enables troubleshooting tools like Wireshark to provide information about wireless protocols and radio signals. AirPcap Classic gives you the power to capture and analyze low-level 802.11b/g wireless traffic, including control, management, and data frames on your Windows workstation or laptop. Per packet information is also available, such as power, hardware timestamps (in microseconds), and receive rate.
AirPcap Tx retains all of the functionality of AirPcap Classic and, additionally, supports packet injection ( the ability to transmit raw 802.11 frames on your network). This capability makes AirPcap Tx an invaluable aid in assessing the security of your wireless network.
AirPcap Tx, like AirPcap Classic, enables troubleshooting tools like Wireshark to provide information about wireless protocols and radio signals. AirPcap Tx gives you the power to capture and analyze low-level 802.11b/g wireless traffic, including control, management, and data frames on your Windows workstation or laptop. Per packet information is also available, such as signal strength, CPU-based timestamps (in microseconds), and receive rate. It also lets you send any of these frame types over the air.
In addition to all of the AirPcap Classic functionality, AirPcap Tx supports the ability to transmit raw 802.11 frames on your network. This capability makes AirPcap Tx an invaluable aid in assessing the security of your wireless network.
AirPcap Tx and Airpcap Nx has 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 Ex/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.
An application, called AirPcapReplay, is included in the AirPcap Software Distribution. The purpose of this application, as the name suggests, is to replay 802.11 network traffic that is contained in a trace file. In addition to the replay feature, AirPcapReplay also allows the user to edit individual packets using a built-in hex editor.
In addition to AirPcapReplay, there are several third-party freeware and open-source tools that are compatible with AirPcap Tx. These tools are typically for advanced users who are interested in securing and/or auditing their wireless networks. One of these, Aircrack-ng, is a well-known suite of tools for auditing wireless networks. It allows various types of penetration tests on a wireless network: http://www.aircrack-ng.org
Unlike passive reception, there are restrictions on the transmission frequencies/channels imposed by various countries. While there are no channel restrictions for monitoring 802.11 traffic, AirPcap Tx will allow transmission on only those channels that are permitted according to the ship-to country.
When monitoring on a single channel is not enough, multiple AirPcap Tx adapters can be plugged into your laptop or a USB hub and provide industry-leading capability for simultaneous multi-channel capture and traffic aggregation. To facilitate the use of this feature, we offer the AirPcap 3-Pack.
