WIFI Signal Widget

Keep precisely within the WIFI hotspot area with the help of this high resolution graphical widget and numeric dBm value. Click the widget for background color change including transparency.

For non techs - dBm is a logarithmic unit and is very convenient for describing RF signal strength which varies a lot! You will generally be between -40 to -90 dBm.

Tech note - -95dBm is the thermal noise floor(kTB) for wifi with a bandwidth of 20 MHz. Sensitivity cannot be better than -95 dBm.
