Title: Silver Spring Networks Milli 5 To: FCC CFR 47 Part 15 Serial #: SSNT122 MPE Issue Date: 20th September 2016 Page: 3 of 4 1. MAXIMUM PERMISSABLE EXPOSURE Calculations for Maximum Permissible Exposure Levels Power Density = Pd (mW/cm ) = EIRP/(4*π*d ) 2 2 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 2 0.6 mW/cm The calculations in the table below use the highest conducted power values together with the lowest antenna gain specified for the EUT. These calculations represent worst case in terms of the exposure levels. Peak Peak Calculated Calculated Minimum Ant Numeric Freq. Band Output Output Safe Power Separation Gain Gain (MHz) Power Power Distance @ Density @ Distance (dBi) (numeric) 2 (dBm) (mW) 0.6 mW/cm 20cm (cm) 902.0 – 928.0 3.0 2.00 23.77 238.23 7.94 0.09 20.0 Note: for mobile or fixed location transmitters the minimum separation distance is 20cm, even if calculations indicate the MPE distance to be less. Specification Maximum Permissible Exposure Limits 2 FCC §1.1310 Limit = 1mW / cm from 1.310 Table 1 This test report may be reproduced in full only.
