W, "S9" signal strength, a strong signal, on the S meter of a typical ham or shortwave radio receiver. The signal intensity (power per unit area) can be converted to received signal power by multiplying by the square. Any RSSI value lower than -dBm is considered poor signal strength.

Based on the client implementation some clients consider -dBm as poor strength as well. WiFi Explorer, as well as other wireless scanning tools, provides an option to display signal strength in dBm or percentage values.

If the signal is greater than one milliwatt, the dBm measurement will be. Interference or weak signal strength can cause a low signal-to-noise. The articles say that Wi-Fi signal strength is always measured in negative. For example, a signal of -dBm (decibel milliwatts) is supposed to be a.
