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. The main reason is that wireless links have lower reliability compared to the reliability of wired links, and therefore the AirPcap Nx 3-Pack provides industry-leading capability for simultaneous multi-channel capture and traffic aggregation. All of the AirPcap offerings will capture full If the decryption is successful, the unencrypted frame is passed to the user application, otherwise the original frame is passed along. These features are fully integrated with Wireshark and CACE Pilot thereby enhancing your troubleshooting effectiveness in multi channel environments. Unless you are transmitting with either AirPcap Tx , Ex or Nx, none of the adapters is detectable by any other wireless station.

AirPcap adapters capture traffic on a single channel at a time.
AirPcap Nx 3-Pack provides industry-leading capability for simultaneous multi-channel capture and traffic aggregation. This has the advantage of minimizing the CPU load during the capture process.
Radiotap and PPI include information such as, transmit rate, signal power, signal quality, channel, and will be displayed by Wireshark in the radiotap header of every frame. The Wireshark Adapters List 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.
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. This includes data frames, control frames and management frames. This device may not cause harmful interference, and 2. airpfap
The center frequency of channel 1 is 2,MHz, channel 2 is 2,MHz, etc. There is a 14th channel whose center frequency is 12MHz above channel Depending on the capabilities of your AirPcap adapter, it can be set to any valid Frequency Range of the device: 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.
In the event that these conditions can not be met for example certain laptop configurations or co-location with another transmitterthen the FCC authorization is no longer considered valid and the FCC ID can not be used on the final product.
If you are a developer, the best sources of information are: This will make it easier for third party applications to understand them. Using this interface, the application will receive the traffic from all installed AirPcap adapters, as if it was coming from a single device.

This includes general 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 and that are within range of the AirPcap adapter.
Depending on the capabilities of a specific AirPcap adapter, it can be set to any valid This includes general When this happens, and if the BSSs are within communication range of each other, the different BSSs compete for the bandwidth of the channel, and this can reduce the overall throughput of sirpcap interfering Ns.
The list of keys can be edited by selecting the Keys tab in the AirPcap control panel Figure 3. All of the AirPcap adapters can operate in a completely passive mode. Operation is subject to the following two conditions: This is a multi-function security tool for Windows that includes wireless access-point and host detection: In some configurations, wireless devices can communicate directly with each other, without airpcaap intermediation of an access point.
The regulations for the 5GHz band are much more complex. This is a well-known suite nd tools for auditing wireless networks: As with the 2.

This feature is useful in distinguishing among the USB AirPcap adapters when multiple adapters are plugged into your system and an easy way to associate the physical adapters with the adapter numbers assigned by the system. The same channel may be used by more than one BSS.
This means that they can capture the traffic on a channel ns associating with an access point, or interacting with any other wireless device. End-users and installers must be provided with antenna installation instructions and transmitter operating conditions for satisfying RF exposure compliance.
Using this interface, the application will receive the traffic from all the installed AirPcap adapters, as if it was coming from a single device. Multiple Channel Capture When monitoring on a single channel is n 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.
