In unguided medium (free space), the electromagnetic (EM) signal wave spreads as it leaves the transmit antenna.  Since the power of the EM signal resides at the surface area of the wave front, signal power is described as signal power density (i.e., watts per area). As the signal propagates away from the transmitter, power density decreases, and attenuation is experienced.

Convert 85 watt to decibels referenced to 1 milliwatt.
