Wifi network analyzers, also known as "packet sniffers" intercept, log and analyze data transferred between two mobile devices for the purpose of troubleshooting network issues, gathering wifi usage statistics, monitoring for security intrusions and for the Blackhat purpose of spying on users within the wifi connection involved in the packet sniffing. Here we review the WireShark Network Analyzer and other free Network data analyzer tools.
Wifi network analyzers come in hardware, as well as software versions. Hardware is used for packet sniffing typically works just like a router, where as software based wifi network analyzers run on the devices being monitored. Software wifi packet sniffers are most commonly used for either the invasion of privacy or others for monitoring server traffic, where as hardware wifi packet sniffers are most commonly used for diagnostics and monitoring for performance and security related purposes.
Packet sniffing, in the wrong context, is illegal and governed by multiple laws. For example, the Wiretap Act states, "to intercept and monitor [communications] placed over their facilities in order to combat fraud and theft of service."
We offer reviews on the top network analysis tools and services. Before purchasing or downloading any packet products, be sure to read our Wifi Network Analysis products and services reviews web pages. We also offer a small Wifi Glossary, which shows you a list of Wifi specific terms and definitions.
