Brilliant tool for the Professional
I work as a wireless engineer for a large Wi-Fi vendor. This is my go-to tool for doing quick sanity checks and making sure that radio settings are correct. The ability to drill down into the Information Elements in the Beacons as well as the ability to extract information from them like QBSS load etc onto the customizable dashboard layout really sets this tool apart form any of its competitors. If you are a wireless engineer or are looking to get into the business of installing/maintaining/administering WLANs and you own a Mac, this should be the first tool you install.
