Reference No.: WTF19S01005314-1W Page 2 of 3 2 RF Exposure Test Requirement: RSS-102 issue 5 clause 4 Test Mode: The EUT work in test mode(Tx). 2.1 Requirements 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 levels in excess limit for maximum permissible exposure. In accordance with 47 CFR FCC Part 2 Subpart J, section 2.1091 this device has been defined as a mobile device whereby a distance of 5mm normally can be maintained between the user and the device. 2.2 The procedures / limit RSS-102 issue 5 clause 4: (Uncontrolled Environment) Frequency Range Electric Field Magnetic Field Power Density Reference Period (MHz) (V/m rms) (A/m rms) (W/ m2) (minutes) 0.003-1021 83 90 - Instantaneous* 0.1-10 - 0.73/ ƒ - 6** 0.5 1.1-10 87/ ƒ - - 6** 10-20 27.46 0.0728 -2 6 20-48 58.07/ ƒ0.25 0.1540/ ƒ0.25 8.944/ ƒ0.5 6 48-300 22.06 0.05852 1.291 6 0.3417 0.3417 0.6834 300-6000 3.142 ƒ 0.008335 ƒ 0.02619 ƒ 6 6000-15000 61.4 0.163 10 6 15000-150000 61.4 0.163 10 616000/ ƒ1.2 150000-300000 0.158 ƒ0.5 4.21 x 10-4 ƒ0.5 6.67 x 10-5 ƒ 616000/ƒ1.2 Note: f = frequency in MHz ; *Plane-wave equivalent power density

Reference No.: WTF19S01005314-1W Page 3 of 3 2.3 MPE Calculation Method Predication of MPE limit at a given distance S = 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) From the peak EUT RF output power, the minimum mobile separation distance, d=5mm, as well as the gain of the used antenna, the RF power density can be obtained 2.4G Mode Antenna Antenna Gain Max.Peak Output Peak Output Power Density Limit of Power Gain (dBi) (numeric) Power (dBm) Power (mW) (mW/cm2) Density (mW/cm2) 2405 0 1.778 -12.81 0.05 0.016666 10 Note: the following is Source-based time-averaged maximum output power Calculation Source-based time- Source-based time-averaged Substituted Frequency averaged maximum maximum output power (0dBm) output power (MHz) (dBμV/m) (dBμV/m) (dBm) 2405 82.39 95.2 -12.81 ======End of Report======
