RF Exposure Requirements:                                                              47 CFR §1.1307(b)

RF Radiation Exposure Limits:                                                          47 CFR §1.1310

RF Radiation Exposure Guidelines:                                                      FCC OST/OET Bulletin Number 65

Limits for General Population/Uncontrolled Exposure in the band of:                    1500 - 100,000 MHz
Power Density Limit:                                                                   1 mW / cm2


Equation:              S = PG / 4R2 or R = √PG / 4S
           Where,      S = Power Density
                       P = Power Input to Antenna
                       G = Antenna Gain
                       R = distance to the center of radiated antenna
