After you manually add a site to the application, it will remember the BSSIDs it previously saw in that environment, and show you comparison data from your last visit. InSSIDer now has the capability of differentiating between different sites. Since the WiSpy Air is acting as a packet capture device in this scenario, there is much more information available to the application for future feature development. The latest version of inSSIDer Pro, when used with the WiSpy Air, can provide you with channel utilization for each AP in the environment.

This is all very handy information to have at your fingertips.

While viewing the client details, the WiSpy Air will follow that client to other channels as it roams. If you expand the details of the client, it will show you the RSSI, PHY type, retry rate, etc. One feature that surprised me was the ability to drill-down into an SSID and be presented with the top clients (based on utilization) on that channel/SSID. Just like with cameras, the best spectrum analyzer you have is the one you have with you. The fact that it’s small enough to keep in your daily laptop bag is a huge bonus. While the spectrum resolution is not great, it is enough to be able to see and identify most interferers. WiSpy Air has all the functionality you’d expect from a basic spectrum analyzer. It also has its own dedicated Wi-Fi chipset so it can monitor Wi-Fi frames to learn more about the Wi-Fi clients and network, in addition to being a spectrum analyzer. The Air Viewer application used to display the data from the WiSpy Air is available for iOS and Android. The WiSpy Air is a dual-band spectrum analyzer (same as the WiSpy dBx), but for mobile devices instead of laptops.
