About these files. They are third-party captures that Airwavz does not host or modify. Capture time is the timestamp of the first packet in the file, in UTC; a few files show timestamp gaps of several days between packets. Follow each source’s terms of use. Captures from the Wireshark wiki were made with a SiliconDust tuner and are listed there as public sample captures. The libatsc3 captures are published in an MIT-licensed repository. To suggest a capture for this page, contact Support.
