RF Exposure

Test Requirement: FCC 47CFR 15.247(i)
Test Date: 2017-3-14
Mode of Operation: Tx mode

Test Method:

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.
This evaluation used FCC 47CFR 2.1091 to perform.
Test Results:

The EUT complied with the requirement(s) of this section.
EUT meets the requirements of these sections as proven through MPE calculation
The MPE calculation for EUT @ 20cm
Based on the highest P =0.711 mW

The power tune up tolerance is -2.48±1.0dBm
Max. duty factor is 100%

Pd = PG/ 4pi*R2 = (0.711 x 1.0)/12.566* (20)2
= (0.711)/12.566x 400= 0.711 /5026.4
= 0.000141mW/cm2

where:
*Pd = power density in mW/cm2
* G = Antenna numeric gain (1.0); Log G = g/10 ( g = 0dBi ).
* P = Conducted RF power to antenna (0.793 mW).
* R = Minimum allowable distance.(20 cm)

*The power density Pd = 0.000141 mW/cm2 is less than 1 mW/cm2 (listed MPE limit)
*The SAR evaluation is not needed ( this is a desk top device, R> 20 cm )
* The EUT( antenna ) must be 0.2 meters away from the General Population.
