NetSpot is a free wireless survey software for Mac OS X. You need just a few clicks to load your office plan or area map and start a network site survey.
Just point to where you are on the map and NetSpot starts measuring wireless signal right away, move around, and collect Wi-Fi data. That’s it: now you have all the needed info to analyze radio signal leakages, discover noise sources, map channel usage, locate effective access points, etc.
Efficiency-wise, your Wi-Fi network needs hotspots placed correctly and radio channels assigned in a proper way: the visual Wi-Fi map you get thanks to NetSpot lets you see all dead zones without coverage and optimize hotspots’ placements; you can see channels’ load and decide how to use them ideally.
NetSpot is also a suitable tool for Wi-Fi planning. Load a map, collect some wireless site survey data, build a comprehensive heatmap of your network.
Now viewing each channel separately is as easy as a pie. Once you locate an empty channel with no wireless networks – it’s the optimal selection for a new Wi-Fi network. NetSpot also lets you easily select channels for new Wi-Fi hotspots with minimal signal to noise ratio.
