4. MAXIMUM PERMISSIBLE EXPOSURE

4.1 RF Exposure Calculation
According to the FCC rule 1.1310 table 1B, the limit for the maximum permissible RF exposure for an uncontrolled environment are f/1500 mW/cm²for the frequency range between 300 MHz and 1 500 MHz and 1.0 mW/cm²for the frequency range between 1 500 MHz and 100 000 MHz. The electric field generated for a 1 mW/cm²exposure is calculated as follows:
E =  (30 * P * G) / d, and S = E² / Z = E² / 377, because 1 mW/cm² = 10 W/m² Where
S = Power density in mW/cm², Z = Impedance of free space, 377  E = Electric filed strength in V/m, G = Numeric antenna gain, and d = distance in meter Combing equations and rearranging the terms to express the distance as a function of the remaining variable d =  (30 * P * G) / (377 *10 S) Changing to units of mW and cm, using P (mW) = P (W) / 1 000, d (cm) = 0.01 * d (m) d = 0.282 *  (P * G) / S Where d = distance in cm, P = Power in mW, G = Numeric antenna gain, and S = Power density in mW/cm²
