RF EXPOSURE MEASUREMENT 3.1 INTRODUCTION Human exposure to RF emissions from mobile devices (47 CFR §2.1091) may be evaluated based on the MPE limits adopted by the FCC for electric and magnetic field strength and/or power density, as appropriate, since exposures are assumed to occur at distances of 20 cm or more from persons. The 1992 ANSI/IEEE standard (See Listed limit table) specifies a minimum separation distance of 20 cm for performing reliable field measurements to determine adherence to MPE limits. If the minimum separation distance between a transmitter and nearby persons is more than 20 cm under normal operating conditions, compliance with MPE limits may be determined at such distance from the transmitter. When applicable, operation instructions and prominent warning labels may be used to alert the exposed persons to maintain a specified distance from the transmitter or to limit their exposure durations and usage conditions to ensure compliance. 3.2 FCC LIMITS FOR MAXIMUM PERMISSIBLE EXPOSURE (MPE) LIMITS FOR GENERAL POPULATION / UNCONTROLLED EXPOSURE Frequency Range (MHz) E-field Strength (E) (V/m) Magnetic Field Strength (H) (A/m) Power Density (S) (mW/cm 2 ) Averaging Time |E| 2 , |H| 2 or S (Minutes) 0.3 -- 1.34 614 1.63 (100)* 30 1.34 -- 30 824/f 2.19/f (180/f 2 )* 30 30 -- 300 27.5 0.073 0.2 30 300 -- 1500 -- -- f/1500 30 1500 -- 100,000 -- -- 1.0 30 *Note: 1. f= Frequency in MHz * Plane-wave Equivalent Power Density 2.The averaging time for General Population/Uncontrolled exposure to fixed transmitters is not applicable for mobile and portable transmitters. See 47 CFR §§2.1091 and 2.1093 on source-based time-averaging requirement for mobile and portable transmitters. 4. CLASSIFICATION OF THE ASSESSMENT METHODS According to user manual, The antenna of the product, under normal use condition is at least 60.1 cm away from the body of the user. Warning statement to the user for keeping at least 60.1 cm separation distance and the prohibition of operating to a person has been printed on the user’s manual. So, this product under normal use is located on electromagnetic far field between the human body. S=PG/4πR² Where: S=power density P=power input to antenna G=power gain of the antenna in the direction of interest relative to an isotropic radiator R=distance to the center of radiation of the antenna 5. EUT OPERATION CONDITION Make the EUT to transmit at channel 4 , channel 11 and channel 19 individually. 6. TEST RESULTS Note: report the worst result in this part Antenna Gain=0 dBi (Numeric 1), π=3.141, Duty cycle=50% Frequency Output Power Output Power Correct Power Power Density Power Density Limit Result MHz dBm mW mW mW/cm 2 mW/cm 2 Pass/Fail 462.6250 41.45 13964 6982 0.3077 0.3084 Pass Note: 1.The output power is refer to AGC09781200201FE10. 2.Correct Power=Output Power*Duty cycle. 3.According to the user manual, the minimum separate distance which used for MPE calculate is 60.1cm.
