FCC ID: 2BTW7-AI201 RF Exposure Evaluation Limits 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 KDB 447498 D01 V06 and 1.1307(b) and 2.1091 Limits for Maximum Permissible Exposure (MPE) Frequency range (MHz) Electric field strength (V/m) Magnetic field strength (A/m) Power density (mW/cm 2 ) Averaging time (minutes) (A) Limits for Occupational/Controlled Exposures 0.3–3.0 614 1.63 *(100) 6 3.0–30 1842/f 4.89/f *(900/f 2 ) 6 30–300 61.4 0.163 1.0 6 300–1500 f/300 6 1500–100,000 5 6 (B) Limits for General Population/Uncontrolled Exposure 0.3–1.34 614 1.63 *(100) 30 1.34–30 824/f 2.19/f *(180/f 2 ) 30 30–300 27.5 0.073 0.2 30 300–1500 f/1500 30 1500–100,000 1.0 30 f = frequency in MHz Friis transmission formula: Pd = (Pout*G)/(4*pi*r 2 ) Where Pd = power density in mW/cm 2 , 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/cm 2 . 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. Test Procedure Software provided by client enabled the EUT to transmit and receive data at lowest, middle and highest channel individually. EIRP=E Meas +20log(d Meas )-104.7 EIRP is the equivalent isotropically radiated power, in dBm E Meas is the field strength of the emission at the measurement distance, in dBμV/m d Meas is the measurement distance, in m Test Result of RF Exposure Evaluation For BT Output power to antenna (dBm) Output power to antenna (mW) Power Density at R=20cm (mW/cm 2 ) Limit (mW/cm 2 ) Result 1.87 1.5382 0.0006 1.0 PASS Remark: antenna gain=3.25dBi For WiFi 2.4G Output power to antenna (dBm) Output power to antenna (mW) Power Density at R=20cm (mW/cm 2 ) Limit (mW/cm 2 ) Result 13.33 21.5278 0.0091 1.0 PASS Remark: antenna gain=3.25dBi For WiFi 5.8G Output power to antenna (dBm) Output power to antenna (mW) Power Density at R=20cm (mW/cm 2 ) Limit (mW/cm 2 ) Result 1.52 1.4191 0.0009 1.0 PASS Remark: antenna gain=5.05dBi For Simultaneous transmitting, 1): The sum of the ratios of the spatially averaged results to the applicable frequency dependent MPE limits =0.0006/1 + 0.0091/1 + 0.0009/1 = 0.0106< 1 Since the sum of the MPE ratios for all simultaneously transmitting antennas incorporated in the device is ≤ 1.0, the EUT is considered to satisfy MPE compliance for simultaneous transmission operations.
