5       RF Exposure Evaluation

5.1    RF Exposure Compliance Requirement
5.1.1 Limits
        According to FCC Part1.1310: The criteria listed in the following table shall be used to evaluate the
        environment impact of human exposure to radio frequency (RF) radiation as specified in part1.1307(b)




Note 1: f = frequency in MHz ; *Plane-wave equivalent power density
Note 2: For the applicable limit, see FCC 1.1310, 680106 D01 RF Exposure Wireless Charging Apps v03
Note 3: Emissions between 100 kHz to 300 kHz should be assessed versus the limits at 300 kHz in Table 1 of
Section 1.1310: 614 V/m and 1.63 A/m. A KDB inquiry is required to determine the applicable exposure limits
below 100 kHz.
Note 4: The aggregate H-field strengths at 15 cm surrounding the device and 20 cm above the top surface
from all simultaneous transmitting coils are demonstrated to be less than 50% of the MPE limit .

5.1.2 Test Procedure
For devices designed for typical desktop applications, such a wireless charging pads, RF exposure evaluation
should be conducted assuming a user separation distance of 20 cm(Top) and 15cm(Edge). E and H field
strength measurements or numerical modeling may be used to demonstrate compliance. Measurements
should be made from all sides and the top of the primary/client pair, with the 20 cm(Top) and 15cm(Edge)
measured from the center of the probe(s) to the edge of the device.

5.1.3 Test Setup




Note: Position A: Front of EUT; Position B: Left of EUT; Position C: back of EUT; Position D: Right of EUT;
Position E: Top of EUT(20 cm measure distance);


5.1.4 Test Results

The EUT does comply with item 5 KDB680106 D01 v03.

(1) Power transfer frequency is less than 1 MHz.
(Conform)

(2) Output power from each primary coil is less than or equal to 15 watts.
(Conform)

(3) The transfer system includes only single primary and secondary coils. This includes charging
systems that may have multiple primary coils and clients that are able to detect and allow coupling
only between individual pairs of coils.
(Conform)

(4) Client device is placed directly in contact with the transmitter.
(Conform)

(5) Mobile exposure conditions only (portable exposure conditions are not covered by this
exclusion).
(Conform)

(6) The aggregate H-field strengths at 15 cm surrounding the device and 20 cm above the top
surface from all simultaneous transmitting coils are demonstrated to be less than 50% of the MPE
limit.
(Conform)
