Here, a home-made bracket
built from a short length
of flat metal bar (from
Home Depot, Lowes, OSH,
etc.) is shown separating
the antennas by a reasonable
4" spacing. |

| 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.
The AirPcap adapter, together with
the Wireshark Network Analyzer,
gives you a detailed view of the
802.11 traffic, including control
frames (ACK, RTS, CTS), management
frames (Beacon, Probe requests and
responses, Association/Disassociation,
Authentication/Deauthentication)
and data frames. The captured frames
include the 802.11 Frame Check Sequence,
and it's possible to capture frames
with an invalid FCS to spot remote
access points with a weak signal.
You will be able to specify the
capture channel and see all the traffic
it carries, even if the channel is
shared by multiple access points.
The AirPcap adapter can be configured
with one or more WEP keys, so that
you will have the option to see (and
filter on) unencrypted traffic in
Wireshark.
The AirPcap adapter captures per-packet
power and rate information. This
is useful for mapping your network,
detecting weak signal areas, and
measuring the transmission efficiency
of the stations.
