Shenzhen Branch Report No.: SZEM160300123402 Page: 6 of 7 5 RF Exposure Evaluation 5.1 RF Exposure Compliance Requirement 5.1.1 Limits According to FCC Part1.1310: The criteria listed in the following table shall be used to evaluate the environment impact of human exposure to radio frequency (RF) radiation as specified in part1.1307(b) F= Frequency in MHz Friis Formula Friis transmission formula: Pd = (Pout*G)/(4* Pi * R 2) Where Pd = power density in mW/cm2 Pout = output power to antenna in mW G = gain of antenna in linear scale Pi = 3.1416 R = distance between observation point and center of the radiator in cm Pd id the limit of MPE, 1 mW/cm2 . If we know the maximum gain of the antenna and the total power input to the antenna, through the calculation, we will know the distance r where the MPE limit is reached. 5.1.2 Test Procedure Software provided by client enabled the EUT to transmit and receive data at lowest, middle and highest channel individually. “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.
