3.6 Simultaneous E-Filed Strength and H-Filed Strength
KDB 447498 points for simultaneous transmission on far-filed measurement,
while for below 30 MHz usually measured at near-filed. KDB680106 require
aggregate leakage fields at 15 cm surrounding the device from all simultaneous
transmitting coils are demonstrated to be less than 50% of the MPE limit;
KDB680106 can accept using field strength, power density, SAR measurements or
computational modeling etc., the specific authorization requirements will be
determined based on the results of the RF exposure evaluation.
Test labs suggest use Computational modelling to calculate Nerve Stimulation
BRs; Computational modelling, such as finite-difference time-domain (FDTD) may
be used to demonstrate compliance with FCC § 1.1310 limits requirement, Basic
Calculations – The following calculations may be used to evaluate systems
without consideration for the effects of phase resulting from multiple
frequency and/or multiple antennas co-located in the measurement space, which
may overestimate the actual result. If the result exceeds the limits, the
advanced calculations described,iln follows may be used.
Where:
E-field measurements
Eave = Spatial average
Ewvarus = E-field at
a measurement point
N = Number of spatially averaged points
And
Where:
H-field levels of magnetic field strength
Have = Spatial average
Hwmaxrvs = H-field at a measurement point
N = Number of spatially averaged points

3.7 Equipment Approval Considerations
The EUT does comply with KDB 680106 D01 as follow table.
Requirements of KDB 680106 DO1 | Yes / No | Description |
---|---|---|
Power transfer frequency is less than 1 MHz | Yes | The device operate in the |
frequency range 110KHz-205KHz
Output power from each primary coil is less than 15 watts| Yes| The maximum
output power for each primary coil is 10W.
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.
| No| The transfer system includes 3 primary coils.
Client device is placed directly in contact with the transmitter.| Yes| Client
device is placed directly in contact with the transmitter.
Mobile exposure conditions only (portable
exposure conditions are not covered by this exclusion).
| Yes| Mobile exposure conditions only
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.| Yes| The EUT 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.
3.8 Conclusion
The detected emissions with a distance of 15cm surrounding the device and 20
cm above the top surface of the device are below the FCC E-Field Strength &
H-Field Strength limits; The detected emissions are below the limitations
according FCC KDB 680106 and confirmed by the FCC according to KDB Inquire.
