2 General Information This report is issued as a duplicate report to BV CPS report no.: SA180627C01. The difference compared with original report is modifying product name of EUT. Due to no effect on RF exposure, the original evaluation result is kept in this report. 3 RF Exposure 3.1 Limits for Maximum Permissible Exposure (MPE) Frequency Range Electric Field Magnetic Field Power Density Average Time (MHz) Strength (V/m) Strength (A/m) (mW/cm2) (minutes) Limits For General Population / Uncontrolled Exposure 0.3-1.34 614 1.63 (100)* 30 2 1.34-30 824/f 2.19/f (180/f )* 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 ; *Plane-wave equivalent power density 3.2 MPE Calculation 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 3.3 Classification The antenna of this product, under normal use condition, is at least 20cm away from the body of the user. So, this device is classified as Mobile Device. 2.1 Antenna Gain WLAN 2.4GHz: PCB antenna with 3.6 dBi gain Zigbee: PIFA antenna with 3.74 dBi gain Report No.: SA181206C23 Page No. 5 / 6 Report Format Version: 6.1.1

3.4 Calculation Result of Maximum Conducted Power Frequency Band Max Power Antenna Gain Distance Power Density Limit Band (MHz) (dBm) (dBi) (cm) (mW/cm2) (mW/cm2) WLAN 2412-2462 22.79 3.6 20 0.087 1.00 Zigbee 2405-2480 4.77 3.74 20 0.001 1.00 Conclusion: The formula of calculated the MPE is: CPD1 / LPD1 + CPD2 / LPD2 + ……etc. < 1 CPD = Calculation power density LPD = Limit of power density WLAN 2.4GHz + Zigbee = 0.087 / 1.00 + 0.001 / 1.00 = 0.088 Therefore the maximum calculations of above situations are less than the “1” limit. --- END --- Report No.: SA181206C23 Page No. 6 / 6 Report Format Version: 6.1.1
