Report No.: 190400328SHA-006 TEST REPORT 2 MPE Assessment Test result: Pass 2.1 MPE Assessment Limit Mobile device exposure for standalone operations: Frequency range E-field strength H-field strength B-field Equivalent plane wave (V/m) (A/m) (uT) power density Seq (W/m2) 0-1 Hz - 3,2 × 104 4 × 104 - 1-8 Hz 10 000 3,2 × 104/f2 4 × 104/f2 - 8-25 Hz 10 000 4 000/f 5 000/f - 0,025-0,8 kHz 250/f 4/f 5/f - 0,8-3 kHz 250/f 5 6,25 - 3-150 kHz 87 5 6,25 - 0,15-1 MHz 87 0,73/f 0,92/f - 1-10 MHz 87/f1/2 0,73/f 0,92/f - 10-400 MHz 28 0,073 0,092 2 400-2 000 MHz 1,375 f1/2 0,0037 f1/2 0,0046 f1/2 f/200 2-300 GHz 61 0,16 0,20 10 Mobile device exposure for simultaneous transmission operations: the sum of the MPE ratios for all simultaneously transmitting antennas incorporated in a host device is ≤ 1.0 TTRFFCCMPE-01_V1© 2018 Intertek Page 6 of 8

Report No.: 190400328SHA-006 TEST REPORT 2.2 Assessment Results Power density (S) is calculated according to the formula: S = P / (4πR² ) Where S = power density in mW/cm² P = Radiated transmit power in mW G = numeric gain of transmit antenna R = distance (cm) As we can see from the test report 190400328SHA-001, 190400328SHA-002, 190400328SHA-004 and 190400328SHA-005: The calculations in the table below use the highest antenna gain or directional gain for EUT. These calculations represent worst case in terms of the exposure levels. The 2.4G Band WiFi and 5G Band WiFi cannot can support simultaneous transmission, the Bluetooth and WiFi can support simultaneous transmission. Frequency Power Directional Gain R S Limits Mode band (MHz) (dBm) dBi (cm) (mW/cm2) (mW/cm2) Bluetooth 2400 -2483.5 6.38 0.13 20 0.0009 1 2400 -2483.5 17.67 1.62 20 0.0169 1 5150-5250 16.27 3.48 20 0.0188 1 WiFi 5250-5350 15.96 3.48 20 0.0175 1 5470-5725 16.71 3.48 20 0.0208 1 5725-5850 16.57 3.48 20 0.0201 1 Note: 1 mW/cm2 from 1.310 Table 1 For the device can support simultaneous transmission, according to 447498 D01 General RF Exposure Guidance v06, For the device consider simultaneous transmission of WiFi and Bluetooth: The worst MPE = 0.0009/1 + 0.0208/1 = 0.0217 mW/cm2 < 1 mW/cm2.
