Maximum Permissible Exposure FCC, Part 15 Subpart C §15.247(b)(5) Industry Canada RSS-210 §14 Calculations for Maximum Permissible Exposure Levels Power Density = Pd (mW/cm2) = EIRP/(4πd2) EIRP = P * G P = Peak output power (mW) G = Antenna numeric gain (numeric) d = Separation distance (cm) Numeric Gain = 10 ^ (G (dBi)/10) P (worst case) = +18.09 dBm, 64.42 mW, Antenna Gain = 5.2 dBi / 3.31 numeric Because the EUT belongs to the General Population/Uncontrolled Exposure the limit of power density is 1.0mW/cm2 Antenna Gain Peak Output Peak Output Calculated RF Exposure Limit (Numeric) Power (dBm) Power (mW) at d=20cm (mW/cm2) (mW/cm2) 3.31 +18.09 64.42 0.04 1 Specification Maximum Permissible Exposure Limits §15.247 (b)(5) Systems operating under the provisions of this section shall be operated in a manner that ensures that the public is not exposed to radio frequency levels in excess of the Commission’s guidelines. See §1.1307 (b)(1) of this chapter. Limit S = 1mW / cm2 from 1.310 Table 1 Note: for mobile or fixed location transmitters the minimum separation distance is 20cm, even if calculations indicate the MPE distance to be less. RSS-210 §14 Before equipment certification is granted, the procedures of RSS-102 must be followed concerning exposure of humans to RF fields.
