Hi,
Microsoft BDA IBDA_SignalStatistics::get_SignalStrength method retrieves a value that indicates the strength of the signal in decibels. (msdn.microsoft.com/en-us/library/dd693437(v=VS.85).aspx)
The decibel (dB) is a logarithmic unit used to express the ratio between two values of a physical quantity. One value ist the signal strength, the other value is a reference value.
What is the reference value?
Is it mW (dBm) or W = 1000 mW (dBW) or something else?
Different drivers return different values with same signal. Difference is up to 70 dB (power ratio 10 000 000).
