RF Field Strength Calculator

ht                  - Height of Transmitting Antenna

hr                 - Height of Receiving Antenna

I                    - Antenna Current

λ                   - Wavelength

d                   - Distance from transmitting antenna

RF field strength is defined as the amount of an induced signal from a transmitting source, in RF and telecom sector, field strength is measured for accessing the signal excitation from transmitter to receiver system and ensuring a robust communication link. 

Because of the exponential proliferation of cellular phones and base stations throughout the world, RF field strength measuring has become critical. People who live near cell phone towers or base stations are the most impacted by RF fields. Exposure to increasing field strengths causes biological tissues to heat up. These frequencies also have other negative biological consequences, such as tissue damage, that lead to numerous brain disorders and tumors, among other things. The RF field strength is measured in terms of V/m and A/m respectively. The field strength for any communication link can be calculated using this calculator.
