How to Use a WLAN Mapper

It is easy to get started using NetSpot as a WLAN mapper. Simply download, install and launch the application. If you have not used NetSpot before, please read "How Do I Start My Survey?" before starting your survey.

The NetSpot survey process involves uploading a map of your network area (or drawing a map of the area using NetSpot's tools). Then you carry your MacBook or laptop to various spots in your network area and take a data sample at each spot. Once you are done with your WLAN map, you can view the visualizations and start troubleshooting any issues. You can make adjustments to your wireless network map and then take a new survey to determine the results of your efforts and get a better WiFi coverage.
