Shanghai Branch Report No.: SHEM180600465303 Page: 8 of 8 5.2 MPE Calculation For FCC: PG According to the formula S= , we can calculate S which is MPE. 4R 2 Note: dBm 1) P (Watts) =Power Input to antenna = 10 10 / 1000 2) G (Antenna gain in numeric) = 10^ (Antenna gain in dBi /10) 3) R = distance to the center of radiation of antenna (in meter) = 20cm 4) MPE limit = 1mW/cm² For BLE The Max Conducted Peak Output Power is 1.10mW The best case gain of the antenna is 0dBi. 0dB logarithmic terms convert to numeric result is nearly 1. PG 1.10 x 1 S= 2 = =0.0002 mW/cm2 4R π 4 ×400 ×3.14 For 2.4G WiFi The Max Conducted Peak Output Power is 48.75mW The best case gain of the antenna is 5dBi. 5dB logarithmic terms convert to numeric result is nearly 3.16. PG 48.75 x 3.16 S= 2 = =0.031 mW/cm2 4R π 4 ×400 ×3.14 The BT and the DTS modules can simultaneous transmitting at frequency 2.4GHz band.But the 0.0002 0.031 maximum rate of MPE is + =0.031<=1.0. according to the KDB447498 section 7.2 1.0 1.0 determine the device is exclusion from SAR test. --End of the Report-- This document is issued by the Company subject to its General Conditions of Service printed overleaf, available on request or accessible at www.sgs.com/terms_and_conditions.htm and, for electronic format documents, subject to Terms and Conditions for Electronic Documents at www.sgs.com/terms_e-document.htm.
