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 maximum tune-up power including tolerance is 5.0 dBm(3.16mW).
[(max. power of channel, mW)/(min. test separation distance, mm)][√f(GHz)]
= 3.16/5*(√2.472) =1.0 <3

So the SAR evaluation is not necessary.

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 Connector Construction
The EUT has 1 internal antenna, the antenna gain is 0 dBi, that fulfill the requirement of the item.
Please refer to the internal photos.

Result: Compliance.

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

FCC §15.247(a) (1) – 20 dB BANDWIDTH TESTING
Applicable Standard
Alternatively, frequency hopping systems operating in the 2400–2483.5 MHz band may have
hopping channel carrier frequencies that are separated by 25 kHz or two-thirds of the 20 dB
bandwidth of the hopping channel, whichever is greater, provided the systems operate with an
output power no greater than 125 mW.

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 on the test table without connection to measurement instrument. Turn on the
EUT. Then set it to any one convenient frequency within its operating range. Set a reference
level on the measuring instrument equal to the highest peak value.
3. Measure the frequency difference of two frequencies that were attenuated 20 dB from the
reference level. Record the frequency difference as the emission bandwidth.
4. Repeat above procedures until all frequencies measured were complete.

FCC §15.247(a) (1) (iii) - QUANTITY OF HOPPING CHANNEL TEST
Applicable Standard
Frequency hopping systems in the 2400–2483.5 MHz band shall use at least 15 channels. The
average time of occupancy on any channel shall not be greater than 0.4 seconds within a period of
0.4 seconds multiplied by the number of hopping channels employed. Frequency hopping systems
may avoid or suppress transmissions on a particular hopping frequency provided that a minimum
of 15 channels are used.

Test Procedure
1. Check the calibration of the measuring instrument (SA) using either an internal calibrator or a
known signal from an external generator.

2. Set the EUT in hopping mode from first channel to last.

3. By using the Max-Hold function record the Quantity of the channel.

FCC §15.247(d) - BAND EDGES TESTING
Applicable Standard
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. Remove the antenna from the EUT and then connect to a low loss RF cable from the antenna
port to a EMI test receiver, then turn on the EUT and make it operate in transmitting mode.
Then set it to Low Channel and High Channel within its operating range, and make sure the
instrument is operated in its linear range.
3. Set RBW/VBW=100/300kHz 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.
