A, Pleasanton, CA 95466 Tel: (925) 249-9123, Fax: (925) 249-9124 1 Test Methodology In this document, we evaluate the RF Exposure to human body due the intentional transmission from the transmitter (EUT). The limit for Maximum Permissible Exposure (MPE) specified in FCC 1.1310 is followed. Through the Friis transmission formula and the maximum gain of the antenna, we can calculate the distance, away from the product, where the limit of MPE is reached. Although the Friis transmission formula is a far field assumption, the calculated result of that is an over- prediction for near field power density. We will take that as the worst case to specify the safety range. 1.1 RF Exposure Limit According to FCC 1.1310 table 1: The criteria listed in the following table shall be used to evaluate the environmental impact of human exposure to radio-frequency (RF) radiation as specified in 1.1307(b) LIMITS FOR MAXIMUM PERMISSIBLE EXPOSURE (MPE) Frequency Electric Field Magnetic Field Power Density Average Time Range Strength (V/m) Strength (A/m) (mW/cm2) (minutes) (MHz) (A)Limits For Occupational / Control Exposures 0.3-1.34 614 1.63 *(100) 6 1.34-30 1842/f 4.89/f *(900/f²) 6 30-300 61.4 0.163 1.0 6 30-1500 … … F/300 6 1500-100000 … … 1.0 6 (B)Limits For General Population / Uncontrolled Exposure 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 30-1500 … … F(MHz)/1500MHz 30 1500-100000 … … 1.0 30 F = Frequency in MHz *=Plane wave equivalent density Report Number: MPE Calculation Page 3 of 20 Model: NVG5X8AC Report Date: June 10, 2019 FCC ID: PGR-NVG5XDBAC; IC: 3439B-NVG5XDBAC
