The term "wireless network analyzer" refers to a type of network traffic interception tool known as wireless packet sniffer or packet analyzer. It is type of software used by computer networking experts, administrators and hackers to intercept, monitor and log wireless network traffic data.
There are many network analyzer software packages available online. Two of the most popular analyzer packages are Acrylic Wi-Fi for Microsoft Windows and the cross-platform, open source Wireshark toolkit.
It is important to distinguish between wireless network mappers that simply facilitate detection of wireless networks and true wireless network analyzers that provide serious tools for professional network troubleshooting and security testing. Some software packages and mobile apps that are branded as "network analyzers" or "Wi-Fi analyzers" only provide the basic functionality necessary to allow novice users to improve connections within their own home wireless networks.
