FCC§15.247 (i), §1.1307 (b) (1) &§2.1093 – RF EXPOSURE
Applicable Standard
According to FCC §2.1093 and §1.1307(b) (1), 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 KDB 447498 D01 General RF Exposure Guidance
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
1. f(GHz) is the RF channel transmit frequency in GHz.
2. Power and distance are rounded to the nearest mW and mm before calculation.
3. The result is rounded to one decimal place for comparison.
4. When the minimum test separation distance is < 5 mm, a distance of 5 mm is applied to determine SAR
test Exclusion.

FCC §15.203 – ANTENNA REQUIREMENT
Applicable Standard
According to FCC § 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 use of a standard antenna jack or electrical connector is
prohibited.
Antenna Connector Construction
The EUT has one PCB antenna arrangement, which was permanently attached and the antenna gain is
-0.58 dBi, fulfill the requirement of this section. Please refer to the EUT photos.

Corrected Factor & Margin Calculation
The Corrected factor is calculated by adding LISN VDF (Voltage Division Factor), Cable Loss and
Transient Limiter Attenuation. The basic equation is as follows:
Correction Factor = LISN VDF + Cable Loss + Transient Limiter Attenuation
The “Margin” column of the following data tables indicates the degree of compliance with the applicable
limit. For example, a margin of 7 dB means the emission is 7 dB below the limit. The equation for margin
calculation is as follows:
Margin = Limit – Corrected Amplitude
Test Results Summary
According to the recorded data in following table, the EUT complied with the FCC Part 15.207,
Refer to CISPR16-4-2:2011 and CISPR 16-4-1:2009, the measured level complies with the limit if
Lm + U(Lm) ≤ Llim + Ucispr
In BACL, U(Lm) is less than Ucispr, if Lm is less than Llim, it implies that the EUT complies with the limit.

Test Procedure
Maximizing procedure was performed on the highest emissions to ensure that the EUT complied with all
installation combinations.
All final data was recorded in Quasi-peak detection mode for frequency range of 30 MHz -1 GHz and 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
Test Results Summary
According to the recorded data in following table, the EUT complied with the FCC Title 47, Part 15,
Subpart C, section 15.205, 15.209 and 15.247.
Refer to CISPR16-4-2:2011 and CISPR 16-4-1:2009, the measured level complies with the limit if
Lm + U(Lm ) ≤ Llim  Ucispr
In BACL, U(Lm ) is less thanUcispr, if Lm is less than Llim, it implies that the EUT complies with the limit.

FCC §15.247(a) (1)-CHANNEL SEPARATION TEST
Applicable Standard
Frequency hopping systems shall have hoping channel carrier frequencies separated by a minimum of 25
kHz or the 20 dB bandwidth of the hopping channel, whichever is greater. 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. The system shall hop
to channel frequencies that are selected at the system hopping rate from a pseudo randomly ordered list of
hopping frequencies. Each frequency must be used equally on the average by each transmitter. The system
receivers shall have input bandwidths that match the hopping channel bandwidths of their corresponding
transmitters and shall shift frequencies in synchronization with the transmitted signals.
Test Procedure
1. Set the EUT in transmitting mode, maxhold the channel.
2. Set the adjacent channel of the EUT and maxhold another trace.
3. Measure the channel separation.

FCC §15.247(a) (1) – 20 dB EMISSION BANDWIDTH
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 without connection to measurement instrument. Turn on the EUT and connect it to
measurement instrument. 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 of spectrum analyzer to 100 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.
