NetSpot is a software tool for Wireless networks assessment, scanning and surveys, analyzing Wi-Fi coverage and performance.[1] It runs on Mac OS X 10.6+ 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 top of that. NetSpot was released in August, 2011 [2] and now available at MacApp Store.[3]


NetSpot provides all professional Wi-Fi site surveys features and maps Wi-Fi coverage of a living area, office space, buildings, etc.[4] It provides visual data to help analyze radio signal leakages, discover noise sources, map channel usage, optimize Access Points locations. Additionally, the application is capable of performing Wi-Fi network planning: the data that are collected help to select channels and placements for new Wi-Fi hotspots. NetSpot can generate survey reports in PDF format.

NetSpot is usually used for[edit]

  • Wi-Fi mapping;
  • Network optimization;[5]
  • Creating WiFi signal strength map;[6]
  • Wi-Fi network trouble-shooting;[7]
  • Wireless network visualisation [8]
  • Wi-Fi signal problems diagnosing;[9]
  • Wireless network coverage analyzing.[10]
