Reference No.: WTS18S10126788-3W Page 2 of 4 2 RF Exposure Test Requirement: FCC Part 1.1307 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 0.2 m normally can be maintained between the user and the device. 2.2 The procedures / limit FCC Part 1.1307: (A) Limits for Occupational / Controlled Exposure Magnetic Field Averaging Time Frequency Range Electric Field Power Density (S) Strength (H) |E|2,|H|2or S (MHz) Strength (E) (V/m) (mW/ cm2) (A/m) (minutes) 0.3-3.0 614 1.63 (100)* 6 3.0-30 1842 / f 4.89 / f (900 / f)* 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 Magnetic Field Averaging Time Frequency Range Electric Field Power Density (S) Strength (H) |E|2,|H|2 or S (MHz) Strength (E) (V/m) (mW/ cm2) (A/m) (minutes) 0.3-1.34 614 1.63 (100)* 30 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 Note: f = frequency in MHz ; *Plane-wave equivalent power density

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=0.2m, as well as the gain of the used antenna, the RF power density can be obtained 2.4G WIFI 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) WiFi 2.50 1.778 20.96 124.74 0.044129 1 433.92MHz 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) 433.92 0.00 1.000 -33.31 0.00 0.000000 0.289 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) 433.92 61.89 95.2 -33.31
