1.4 Test Methodology

All measurements contained in this report were conducted with ANSI C63.4-2003, American National Standard
for Methods of Measurement of Radio-Noise Emissions from Low-Voltage Electrical and Electronic Equipment in
the range of 9 kHz to 40 GHz.

The equipment under test (EUT) was configured to measure its highest possible emission level. The test modes
were adapted according to the Operating Instructions and let the EUT keep transmitting.

1.5 Test Facility

The test facility is recognized, certified, or accredited by the following organizations:
United States of American Federal Communications Commission (FCC), and the registration number is 556682
Certification and Engineering Bureau of Industry Canada for radio equipment testing with the registration number
is 6002.
All measurement required was performed at laboratory of SGS-CSTC Standards Technical Services Co., Ltd.,
No.1 Workshop, M-10, Middle Section, Science & Technology Park, Nanshan District, Shenzhen, Guangdong,
China.

1.6 EUT Exercise Software

The EUT exercise program used during the testing was designed to exercise the system components. The test
software is started while the whole system is on.

3. §15.203 - ANTENNA REQUIREMENT

3.1 Standard Applicable

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.

3.2 Test Result

This product has a fixed antenna, fulfill the requirement of this section.

4. §15.205, §15.209, §15.249 (a)- RADIATED EMISSION

4.1 Measurement Uncertainty

Based on NIS 81, The Treatment of Uncertainty in EMC Measurements, the best estimate of the uncertainty of a
radiation emissions measurement is +3.0 dB.

4.2 Standard Applicable

According to §15.249(a), the field strength of emissions from intentional radiators operated within these
frequency bands shall comply with the following:

Fundamental Frequency Field strength of fundamental Field strength of harmonics
(milli-volts/meter) (micro-volts/meter)
902-928 MHz 50 500
2400-2483.5 MHz 50 500
5725-5875 MHz 50 500
24.0-24.25 GHz 250 2500
The emission limit in this paragraph is based on measurement instrumentation employing an average detector. The
provisions in §15.35 for limiting peak emissions apply.

EMISSIONS RADIATED OUTSIDE OF THE SPECIFIED FREQUENCY BANDS, EXCEPT FOR HARMONICS, SHALL BE ATTENUATED
BY AT LEAST 20 dB BELOW THE LEVEL OF THE FUNDAMENTAL OR TO THE GENERAL RADIATED EMISSION LIMITS IN
15.209,WHICHEVER IS THE LESSER ATTENUATION.

Emissions that fall in the restricted bands (15.205) must be less than 54dBuV/m otherwise the spurious and
harmonics must be attenuated by at least 20dB.

4.5 Corrected Amplitude & Margin Calculation

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

Corr. Ampl. = Indicated Reading + Ant. Factor + Cable Loss – Ampl. Gain

The “Margin” column of the following data tables indicates the degree of compliance with the applicable limit.
For example, a margin of -6dBμV means the emission is 6dBμV below the maximum limit for Class B. The
equation for margin calculation is as follows:

Margin = Corr. Ampl. – FCC Part 15 Limit
