Bay Area Compliance Laboratories Corp.( Kunshan) Report No.: RSHA181115002-00C FCC §1.1310 & §2.1091 –MAXIMUM PERMISSIBLE EXPOSURE (MPE) Applicable Standard According to subpart §2.1091 and subpart §1.1310, systems operating under the provisions of this section shall be operated in a manner that ensures that the public is not exposed to radio frequency energy level in excess of the Commission’s guidelines. Limits for Maximum Permissible Exposure (MPE) (§1.1310, §2.1091) (B) Limits for General Population/Uncontrolled Exposure Frequency Range Electric Field Magnetic Field Power Density Averaging Time (MHz) Strength (V/m) Strength (A/m) (mW/cm2) (minutes) 0.3-1.34 614 1.63 *(100) 30 1.34-30 824/f 2.19/f *(180/f²) 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; According to §1.1310 and §2.1091 RF exposure is calculated. Calculated Formulary: Predication of MPE limit at a given distance S = PG/4πR² = power density (in appropriate units, e.g. mW/cm2); P = power input to the antenna (in appropriate units, e.g., mW); G = power gain of the antenna in the direction of interest relative to an isotropic radiator, the power gain factor, is normally numeric gain; R = distance to the center of radiation of the antenna (appropriate units, e.g., cm); For simultaneously transmit system, the calculated power density should comply with: Calculated Data: Tune-up Frequency Antenna Gain Conducted Evaluation Power MPE MPE Mode Range Power Distance Density Limit ratio (MHz) (cm) (mW/cm2) (mW/cm2) (dBi) (numeric) (dBm) (mW) Bluetooth 2402-2480 0.00 1.00 7.00 5.01 50 0.0002 1.0 0.0002 3652.5- LTE 17.00 50.12 16.50 44.67 50 0.0713 1.0 0.0713 3697.5 FCC Part 90 Page 11 of 81

Bay Area Compliance Laboratories Corp.( Kunshan) Report No.: RSHA181115002-00C Note: Bluetooth and LTE can transmit simultaneously; the worst condition is Bluetooth & LTE, as below: =0.0002+0.0713=0.0715 < 1.0 Result: The device meet FCC MPE at 50 cm distance. FCC Part 90 Page 12 of 81
