Report No.: NTC2012059F-1 FCC ID: PRDRXOX RF EXPOSURE EVALUATION EUT Specification EUT 2.4GHz Dongle Model Name MQW Frequency band (Operating) 2.402GHz ~ 2.480GHz WLAN: 5.18GHz ~ 5.32GHz / 5.50GHz ~ 5.70GHz WLAN: 5.745GHz ~ 5825GHz Others(2402-2480MHz) Device category Portable (<20cm separation) Mobile (>20cm separation) Others ___ Antenna diversity Single antenna Multiple antennas Tx diversity Rx diversity Tx/Rx diversity Max. output power 83.95dBuV/m (-11.31dBm)(0.07mW) Antenna gain -2.58dBi Evaluation applied MPE Evaluation SAR Evaluation Standard Requirement Portable Device According to §15.247(i) and §1.1307b(1), 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 of the Commission’s guidelines. See KDB 447498 D01 General RF Exposure Guidance v05, section 4.3.1. The 1-g and 10-g SAR test exclusion thresholds for 100 MHz to 6 GHz at test separation distances ≤ 50 mm are determined by: [(max. power of channel, including tune-up tolerance, mW)/(min. test separation distance, mm)] ·[√f(GHz)] ≤ 3.0 for 1-g SAR and ≤ 7.5 for 10-g extremity SAR, 16 where ·f(GHz) is the RF channel transmit frequency in GHz ·Power and distance are rounded to the nearest mW and mm before calculation17 ·The result is rounded to one decimal place for comparison The test exclusions are applicable only when the minimum test separation distance is ≤ 50 mm and for transmission frequencies between 100 MHz and 6 GHz. When the minimum test separation distance is < 5 mm, a distance of 5 mm is applied to determine SAR test exclusion. Dongguan Nore Testing Center Co., Ltd. Report No.: NTC2012059F-1 FCC ID: PRDRXOX Measurement Result Channel Frequency (MHz) Max Output power (dBuV/m) Max Output power (dBm) Max Output power (mW) Calculation Value (Note 1) Threshold Value 2402 83.95 -11.31 0.07 0.022 3.0 2440 83.73 -11.53 0.07 0.022 3.0 2480 82.52 -12.74 0.05 0.016 3.0 EIRP=E-104.8+20logD=83.95-104.8+20log3=-11.31dBm Note 1: Calculation Value =[(max. power of channel, mW)/(min. test separation distance, mm)] ·[√f(GHz)]. Fox example: 0.07 /5*√2.402=0.022 ≤ 3.0 According to KDB447498 D01 V05, threshold at which no SAR required is ≤3.0 for 1-g SAR, separation distance is 5mm, and no SAR measurement is required. The SAR measurement is not necessary.
