An Apple Fanboy once told me that there is an app for everything, just the way, there is a solution to every problem. Now there is app to scan your WiFi as well.
Introducing, the WiFi Scanner, which is the most feature rich and complete WiFi scanning app on the app store. It is a great tool for personal use and for IT professionals. All features are available on 10.6 and later (Snow Leopard and Lion).
WiFi Scanner is an 802.11/WiFi wireless scanner and connection manager for 802.11 a/b/g/n networks. This app is an easy to use tool for designing, verifying, and troubleshooting WiFi coverage. This tool provides information such as signal strength, noise, manufacturer name based on Mac address prefix of device, known as Organizationally Unique Identifier (OUI), and AP channel assignments for WiFi access points.
WiFi Scanner has been created by AccessAgility LLC, a Service-Disabled Veteran-Owned Small Business (SDVOSB) with offices in the Washington, DC metro area. AccessAgility supports government organizations such as Federal Aviation Administration (FAA), United States Department of Homeland Security (DHS), United States Department of Veterans Affairs (VA), National Geospatial-Intelligence Agency (NGA) and Department of Defense (DoD). This company provide government and commercial organizations with consulting and program management support for systems design and integration, systems and network administration, data center operations and security.
WiFi Scanner can also be used a security tool for detecting unauthorized and rogue access points. This app includes an audio alert (beep) feature. This feature is directly related to RSSI / access point signal strength. It can be used to track down devices by listening for beep frequency instead of watching app screen.
