Bay Area Compliance Laboratories Corp. (Dongguan)                           Report No.: RDG190708002-00B

FCC §15.247 (i) & §1.1310 & §2.1093- RF EXPOSURE
Applicable Standard
According to§15.247(i) and §1.1310, systems operating under the provisions of this section shall be
operated in a manner that ensure that the public is not exposed to radio frequency energy level in excess of
the Commission’s guideline.

According to KDB447498 D01 General RF Exposure Guidance v06:

The 1-g and 10-g SAR test exclusion thresholds for 100 MHz to 6 GHz at test separation distances ≤ 50
mm are determined by:
[(max. power of channel, including tune-up tolerance, mW)/(min. test separation distance,
mm)] · [√f(GHz)] ≤ 3.0 for 1-g SAR and ≤ 7.5 for 10-g extremity SAR, where
        • f(GHz) is the RF channel transmit frequency in GHz
        • Power and distance are rounded to the nearest mW and mm before calculation
        • The result is rounded to one decimal place for comparison
        • 3.0 and 7.5 are referred to as the numeric thresholds in the step 2 below

The test exclusions are applicable only when the minimum test separation distance is ≤ 50 mm and for
transmission frequencies between 100 MHz and 6 GHz. When the minimum test separation distance is < 5
mm, a distance of 5 mm according to 5) in section 4.1 is applied to determine SAR test exclusion.


Measurement Result

The max conducted power including tune-up tolerance is 1 dBm (1.26 mW).
[(max. power of channel, mW)/(min. test separation distance, mm)][√f(GHz)]
=1.26/5*(√2.480) = 0.4< 3.0

So the stand-alone SAR evaluation is not necessary.




                                                                                                 Page 9 of 28


Bay Area Compliance Laboratories Corp. (Dongguan)                             Report No.: RDG190708002-00B

FCC §15.203 - ANTENNA REQUIREMENT
Applicable Standard
According to § 15.203, an intentional radiator shall be designed to ensure that no antenna other than that
furnished by the responsible party shall be used with the device. The use of a permanently attached
antenna or of an antenna that uses a unique coupling to the intentional radiator shall be considered
sufficient to comply with the provisions of this section. The manufacturer may design the unit so that a
broken antenna can be replaced by the user, but the user of a standard antenna jack or electrical connector
is prohibited. The structure and application of the EUT were analyzed to determine compliance with
section §15.203 of the rules. §15.203 state that the subject device must meet the following criteria:

a. Antenna must be permanently attached to the unit.
b. Antenna must use a unique type of connector to attach to the EUT.
c. Unit must be professionally installed, and installer shall be responsible for verifying that the correct
   antenna is employed with the unit.


Antenna Information And Connector Construction
The EUT has one internal antenna arrangement, and the antenna gain is -1.0 dBi, fulfill the requirement of
this section. Please refer to the EUT photos.

Result: Compliance.

FCC §15.209, §15.205, §15.247(d) - SPURIOUS EMISSIONS
Applicable Standard
FCC §15.247 (d); §15.209; §15.205

EUT Setup
Below 1GHz:




Above 1GHz:




The radiated emission Below 1GHz tests were performed in the 10 meters chamber, above 1GHz tests
were performed in the 3 meters chamber B, using the setup accordance with the ANSI C63.10-2013. The
specification used was the FCC 15.209, and FCC 15.247 limits.

The external I/O cables were draped along the test table and formed a bundle 30 to 40 cm long in the
middle.

The spacing between the peripherals was 10 cm.




                                                                                              Page 11 of 28

EMI Test Receiver & Spectrum Analyzer Setup

The system was investigated from 30 MHz to 25 GHz.

During the radiated emission test, the EMI test receiver & Spectrum Analyzer Setup were set with the
following configurations:

30MHz-1000MHz:

                    Measurement             RBW            Video B/W       IF B/W

                                                <98%           1MHz            1/T

Note: T is minimum transmission duration

If the maximized peak measured value complies with under the QP/Average limit more than 6dB, then it is
unnecessary to perform an QP/Average measurement.


Test Procedure

Maximizing procedure was performed on the highest emissions to ensure that the EUT complied with all
installation combinations.

Data was recorded in Quasi-peak detection mode for frequency range of 30 MHz-1 GHz, peak and
Average detection modes for frequencies above 1 GHz.


Corrected Amplitude & Margin Calculation

The Corrected Amplitude is calculated by adding the Antenna Factor and Cable Loss, and subtracting the
Amplifier Gain from the Meter Reading. The basic equation is as follows:

        Corrected Amplitude = Meter Reading + Antenna Factor + Cable Loss - Amplifier Gain

The “Margin” column of the following data tables indicates the degree of compliance with the applicable
limit. For example, a margin of 7dB means the emission is 7dB below the limit. The equation for margin
calculation is as follows:

        Margin = Limit –Corrected Amplitude




                                                                                             Page 12 of 28

FCC §15.247(b) (3) - MAXIMUM PEAK CONDUCTED OUTPUT POWER
Applicable Standard
According to FCC §15.247(b) (3), for systems using digital modulation in the 902-928 MHz, 2400-2483.5
MHz, and 5725-5850 MHz bands: 1 Watt. As an alternative to a peak power measurement, compliance
with the one Watt limit can be based on a measurement of the maximum conducted output power.
Maximum Conducted Output Power is defined as the total transmit power delivered to all antennas and
antenna elements averaged across all symbols in the signaling alphabet when the transmitter is operating at
its maximum power control level. Power must be summed across all antennas and antenna elements. The
average must not include any time intervals during which the transmitter is off or is transmitting at a
reduced power level. If multiple modes of operation are possible (e.g., alternative modulation methods),
the maximum conducted output power is the highest total transmit power occurring in any mode.


Test Procedure
1. Place the EUT on a bench and set it in transmitting mode.
2. Remove the antenna from the EUT and then connect a low loss RF cable from the antenna port to test
   equipment.
3. Add a correction factor to the display.
4.

FCC §15.247(d) – 100 kHz BANDWIDTH OF FREQUENCY BAND EDGE
Applicable Standard
According to FCC§15.247(d):In any 100 kHz bandwidth outside the frequency band in which the spread
spectrum or digitally modulated intentional radiator is operating, the radio frequency power that is
produced by the intentional radiator shall be at least 20 dB below that in the 100 kHz bandwidth within the
band that contains the highest level of the desired power, based on either an RF conducted or a radiated
measurement, provided the transmitter demonstrates compliance with the peak conducted power limits. If
the transmitter complies with the conducted power limits based on the use of RMS averaging over a time
interval, as permitted under paragraph (b)(3) of this section, the attenuation required under this paragraph
shall be 30 dB instead of 20 dB. Attenuation below the general limits specified in §15.209(a) is not
required. In addition, radiated emissions which fall in the restricted bands, as defined in §15.205(a), must
also comply with the radiated emission limits specified in §15.209(a) (see §15.205(c)).


Test Procedure
1. Check the calibration of the measuring instrument using either an internal calibrator or a known signal
   from an external generator.
2. Position the EUT without connection to measurement instrument. Turn on the EUT and connect its
   antenna terminal to measurement instrument via a low loss cable. Then set it to any one measured
   frequency within its operating range, and make sure the instrument is operated in its linear range.
3. Set RBW to 100 kHz and VBW of spectrum analyzer to 300 kHz with a convenient frequency span
   including 100 kHz bandwidth from band edge.
4. Measure the highest amplitude appearing on spectral display and set it as a reference level. Plot the
   graph with marking the highest point and edge frequency.
5. Repeat above procedures until all measured frequencies were complete.
