Field strength and Power

Song Tiandi

i can simulate a scenario with a sender and a predicttion point in winprop proman. For the same prediction point i can get power and Field strength. It seems that they have a constant difference and frequency depedent. The results showned in the pictures is simulated with a anttena frequency of 2000MHz. What is the relationship between Fieldstrength(dBuV/m) and Power(dBm)? how are they calculated? 

Thanks for your answer!

The general formula (ignoring the Rx antenna gain, i.e. assuming isotropic receiving antenna) is:

Rx power [dBm] = e [dBuV/m] – 77.21 – 20*log(f/MHz)
