Title: Silver Spring Networks LNIC To: FCC CFR 47 Part 1.1310 Serial #: SSNT136 MPE Issue Date: 3rd May 2017 Page: 2 of 3 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 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 0.0 1.00 23.77 238.23 5.62 0.047 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 FCC §1.1310 Limit = f/1500 from 1.310 Table 1 for devices operating in the 900 MHz band, where f = frequency in MHz This test report may be reproduced in full only.
