iwScanner vs NetSpot

iwScanner is a free Linux wireless scanner with a graphical interface. It detects wireless networks and displays each access point, MAC address, channel, and encryption type. A signal chart shows the strength of detected networks, and scanning speed can be adjusted. The program uses wireless-tools and is ready to run when iwlist is available. It is designed in Glade and written in Python; the maker says PyGTK is needed in a Linux environment. iwScanner can open and save NetDetect (.ndd) and NetStumbler (.ns1) files, and the source is included with the download. The latest listed release is version 0.2.4, dated 2010-04-15, offered as an Ubuntu deb package and a generic Linux tarball. That release fixes networks being incorrectly detected as WPA2. Notes for version 0.2.3 add support for the rt2860sta card. The maker identifies Renzo Bertuzzi as author and invites email contact.

NetSpot is a Wi-Fi app for network planning, wireless surveys, analysis, and troubleshooting. Inspector mode shows nearby networks and details including channels, vendors, security type, bands, signal, and noise. Survey mode creates interactive, color-coded heatmaps with more than 20 visualizations and customizable reports. Planning mode supports predictive surveys and network design, including multi-floor planning. Survey data can be exported as PDF or CSV, and heatmaps saved as PNG. Active survey throughput testing can use Iperf 3 or custom speed-test servers. NetSpot says survey, scan, heatmap, network, and location data are processed locally rather than automatically sent to Etwok. Desktop editions support offline activation and can run entirely offline afterward. Optional anonymized, aggregated usage statistics can be disabled in Preferences. The free edition is for personal and evaluation use on macOS and Windows. Paid plans are listed from $199. The seven-day full-featured PRO trial requires a valid corporate email and an explanation for the request.
