Report No.: 18A0319R-SAUSP03V00 2. RF Exposure Evaluation 2.1. Standard Applicable According to 1.1307 (b)(1), systems operating under the provisions of this section shall be operated in a manner that ensure that the public is not exposed to radio frequency energy level in excess of the Commission’s guideline. 2.2. Measurement Result: According to KDB Publication 447498 D01, section 4.3.1, per the calculations of item 1 (Power(mW)/separation (mm)*sqrt(f(GHz)≤3.0), SAR is required as shown in the table below where calculated values are greater than 3.0: 1.) Operation frequency = 2450MHz and antenna separation distance = 5mm, Body SAR Test Exclusion Threshold = 10mW Maximum peak output power Body SAR Test Frequency Band Peak Gain: 1.2dBi Exclusion Threshold Calculated Threshold Value (MHz) conducted EIRP EIRP (≦3.0 SAR is not required) (mW) (dBm) (dBm) (mW) 2402 2.74 3.94 2.48 10 0.768 Note1: The SAR/MPE measurement is not necessary. Note2: The conducted maximum peak output power is refer to report No.: 18A0319R-RFUSP01V00 and 18A0319R-RFUSP01V00-A from the DEKRA. Page: 4 of 4
