Ever wanted to be able to test your home or office Wi-Fi connection in real-time to determine where the strongest signal is? Thanks to a free program called NetSpot, you can do just that. NetSpot is an easy to use Mac OS X application which allows for wireless site survey, Wi-Fi analysis, and network troubleshooting. The software is compatible with any MacBook (works on my iMac too) running a standard 802.11 a/b/g/n wireless network adapter and is running Mac OS X 10.6 or later.

Now NetSpot is indeed free to use, but only for non-commercial use & the free version does have limited features. The free version includes support for 802.11 a/b/g/n WLAN and both 2.4 & 5 GHz channel bands. By utilizing this technology you can receive real-time network discovery and analysis, multi-zone surveys, security detection options, automatic detection of AP locations, PDF exporting, and much more.

If you are looking to expand your free license to include more advanced features or want to use NetSpot for commercial use, you'll need to upgrade to a ‘Pro' or ‘Enterprise' version. The premium versions include priority support, active scanning, multi-floor scanning, built-in Wi-Fi troubleshooting, advanced grouping, and among other things.

If you're looking to do perform some serious Wi-Fi analysis, I highly recommend giving NetSpot a try. It is an excellent companion to help determine where to place your computer, Wi-Fi extender, or reposition your router in order to receive the strongest signal and connection strength.
