Question

A base station cellular communication systems lossless antenna has a maximum gain of 16 dB (above isotropic) at 1,900 MHz. Assuming the input power to the antenna is 8 watts, what is the maximum radiated power density (in watts/cm2) at a distance of 100 meters? This will determine the safe level for human exposure to electromagnetic radiation.
