Field strength and Power
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)
Thank you for the reply. It's really useful. But may I know what is the calculation behind 77.21?
Altair EmployeePlease find attached a document explaining the calculation.
