NetSpot is a software tool for wireless network assessment, scanning, and surveys, analyzing Wi-Fi coverage and performance.[1] It runs on Mac OS X 10.6+ and Windows 7-8-10 and supports 802.11n, 802.11a, 802.11b, and 802.11g wireless networks. NetSpot uses the standard Wi-Fi network adapter and its Airport interface to map radio signal strength and other wireless network parameters, and build reports on that. NetSpot was released in August, 2011[2] and available at MacApp Store.[3]


NetSpot provides all professional wireless site survey features for Wi-Fi and maps coverage of a living area, office space, buildings, etc.[4] It provides visual data to help analyze radio signal leaks, discover noise sources, map channel use, optimize access point locations. Also, the application can perform Wi-Fi network planning: the data that are collected help to select channels and placements for new hotspots. Survey reports can be generated in PDF format.
