The formula used is: distance = 10 ^ ((27.55 - (20 * log10(frequency)) + signalLevel)/20) Example: frequency = 2412MHz, signalLevel = -57dbm, result = 7.000397427391188m. This formula is transformed form of Free Space Path Loss(FSPL)formula. Here the distance is measured in meters and the frequency - in megahertz.
