RDWN39-U10 MPE Maximum Permissible Exposure 4.9 GHz Licensed Operation FCC, Part 15 §1.1310 Calculations for Maximum Permissible Exposure Levels Power Density = Pd (mW/cm2) = EIRP/(4d2) EIRP = P * G P = Peak output power (mW) G = Antenna numeric gain (numeric) d = Separation distance (cm) Numeric Gain = 10 ^ (G (dBi)/10) Because the EUT belongs to the General Population/Uncontrolled Exposure the limit of power density is 1.0 mW/cm2 The calculations in the table below use highest gain antennas for the client EUT. Where the antenna gain exceeds 6dBi the transmitter power is reduced where necessary to meet the EIRP requirements. These calculations represent worst case in terms of the exposure levels. Specification Maximum Permissible Exposure Limits FCC §1.1310 Limit = 1mW / cm2 from 1.310 Table 1 Ref FCC KDB 447498 General RF Exposure Guidance RSS-Gen §5.6 Category I and Category II equipment shall comply with the applicable requirements of RSS-102. Laboratory Measurement Uncertainty for Power Measurements Measurement uncertainty 1.33 dB
