[Visualization] What is the Signal Level?

The signal level is the strength of your Wi-Fi signal. The Signal visualization is provided to give you a better understanding of your Signal-to-Noise Ratio (SNR). Viewing the Signal and Noise separately can help to identify underlying problems that are causing you to have a poor SNR. If you hover over the measurement markers on the map and look at the AP names on the left, you can see the exact signal levels for each location.

Get started with NetSpot WiFi tool for macOS

If your signal levels are too low, see Troubleshooting Low Signal Level for strategies to correct it. NetSpot PRO users have access to Automated Troubleshooting,to help identify and fix signal issues. You may also find “Why am I not getting perfect Wi-Fi coverage?” useful.

There are several ways you can adjust this heatmap view:

    • Wi-Fi Network: Each Wi-Fi network detected can be mapped individually. Simply check the box next to the network(s) you wish to view on the left-hand side of the NetSpot window.
    • settings gear icon

      Project Configuration icon

      Wi-Fi Channel: By clicking on the Project Configuration gear icon (on the bottom-left), you can also view the signal level by channel.

    • View: By clicking on the Project Configuration gear icon and selecting Toggle, you can choose whether to show your path, sampling points, and AP titles on the map.
    • visualization gear icon

      Visualization Configuration icon

      AP Detection Proximity: By clicking the Visualization Configuration gear icon (next to the visualization drop-down menu), you can filter out weaker access points (APs) by adjusting the AP detection proximity slider. The default is -60dBm.

    • Min/Max Signal Level: By clicking the Visualization Configuration icon, the colors assigned to the signal level range can be adjusted by changing the Min Signal Level and Max Signal Level sliders. The default range is set to -96dBm (minimum) and -10dBm (maximum).
