SGS-CSTC Standards Technical Services Co., Ltd. Shenzhen Branch Report No.: SZEM181200116303 Page: 7 of 8 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.

SGS-CSTC Standards Technical Services Co., Ltd. Shenzhen Branch Report No.: SZEM181200116303 Page: 8 of 8 4.1.3 EUT RF Exposure Evaluation Antenna Gain: 2dBi Antenna Gain: The maximum Gain measured in fully anechoic chamber is 1.58 in linear scale. Output Power Into Antenna & RF Exposure Evaluation Distance: Channel Frequency Max Conducted Output Power Power Density Limit Result (MHz) Peak Output to Antenna at R = 20 cm Power (dBm) (mW) (mW/cm2) Lowest 2412 21.37 137.09 0.043 1.0 PASS Note: Refer to report No. SZEM181200116302 for EUT test Max Conducted Peak Output Power value. The distance r (4th column) calculated from the Fries transmission formula is far greater than 20 cm separation requirement. - End of the Report -
