FRISS Equation Simulation?

[Skku]

Hello

I have a very quick and kinda naive question.

As we all know that Friss equation is Pr=P_TG_T G_Rλ² / (4*pi*Dist)²

So what is the value Pr if PT=1.3Watt, Dist=1.5Meter, λ=0.43, G_T=6dBi, and G_R=6dBi.

Your kind reply will be very much appriciated.

Everything calculated here https://en.wikipedia.org/wiki/Free-space_path_loss

B.t.w., d < 10 λ is near field where friis equation isn't accurate.

So what is the value Pr if PT=1.3Watt, Dist=1.5Meter, λ=0.43, G_T=6dBi, and G_R=6dBi.

The answer for the given data is: Pr = 0.0108W or +10.3dBm

The answer for the given data is: Pr = 0.0108W or +10.3dBm

Thank you so much.
How can we convert 6dBi into any numeric value?
