“Along with outstanding 802.11n protocol support, the physical layer information reported on a per-packet basis, such as noise and signal modulation, has proved invaluable.? Larry Averitt Intel Corporation Mobility Group

AirPcap N continues the tradition of AirPcap by providing the first open, affordable, and easy-to-deploy 802.11n packet capture solution for the Windows platform.

802.11n is an exciting new technology, but it introduces many potential problems due to its complexity and the need for coexistence with existing 802.11b, a, and g networks.

AirPcap N can provide complete wireless visibility.  It can capture any 802.11b and g frame just like the AirPcap Classic adapter, plus 802.11n and 802.11a traffic.  This includes general 802.11 information such as data, management, and control frames along with 802.11n-specific information such as HT information, aggregated MPDUs, and aggregated MSDUs.

Features

• Captures 802.11n traffic on 20 and 40 MHz channels thanks to the included specialized capture adapter.
• Detailed decoding of control, management, and data frames in Wireshark®, including A-MSDUs, A-MPDUs, and HT frames.
• Support for 2.4 GHz and 5 Ghz channels.
• Per-packet radio information, including:
  - Microsecond hardware timestamps
  - Receive rate
  - Signal noise
  - Receive power
• Integration with the Wireshark open-source network protocol analyzer, with hundreds of dissected network protocols.
