Wireless Forensics is a discipline included within the computer
forensic science, and specifically, within the network forensic field,
and it's a term coined by Marcus Ranum in 1997. Its main goal is to
provide the methodology and tools required to collect and analyze
(wireless) network traffic that can be presented as valid digital
evidence in a court of law. The evidence collected can correspond to
plain data or, with the broad usage of Voice-over-IP (VoIP)
technologies, especially over wireless, can include voice
conversations.
