Note:
1. The EUT supports Cyclic Delay Diversity (CDD) mode, and CDD signals are correlated.
For CDD transmissions, directional gain is calculated as follows, NANT = 2, NSS = 1.
If all antennas have the same gain, GANT, Directional gain = GANT + Array Gain, where Array Gain is as
follows.
•
For power spectral density (PSD) measurements on all devices,
Array Gain = 10 log (NANT/ NSS) dB = 3.01;
•
For power measurements on IEEE 802.11 devices,
Array Gain = 0 dB for NANT ≤ 4;
2. The EUT also supports Beam Forming mode, and the Beam Forming support 802.11n/ac, not include
802.11a/b/g.
Directional gain = GANT + BF Gain, BF Gain was declared by the applicant.
3. These antennas have Cross-Polarized design, the detail see the antenna specification.
4. For Model No.: APEX0374, we selected the max peak gain antenna of each type to perform RF testing.

2.8. Device Capabilities
This device contains the following capabilities:
802.11a/b/g/n/ac Wi-Fi & Bluetooth v4.0 single mode
Note: 5GHz (NII) operation is possible in 20MHz, 40MHz and 80MHz channel bandwidths. The
maximum achievable duty cycles for all modes were determined based on measurements performed
on a spectrum analyzer in zero-span mode with RBW = 8MHz, VBW = 50MHz, and detector =
average per the guidance of Section B)2)b) of KDB 789033 D02v02r01. The RBW and VBW were
both greater than 50/T, where T is the minimum transmission duration, and the number of sweep
points across T was greater than 100. The duty cycles are as follows:

DESCRIPTION OF TEST
3.1. Evaluation Procedure
The measurement procedures described in the American National Standard for Testing Unlicensed
WirelessDevices (ANSI C63.10-2013), and the guidance provided in KDB 789033 D02v02r01 were
used in themeasurement of the ACCESS POINT.
Deviation from measurement procedure…………………………….....................................None
3.2. AC Line Conducted Emissions
The line-conducted facility is located inside an8'x4'x4' shielded enclosure. A 1m x 2m wooden table
80cm high is placed 40cm away from the vertical wall and 80cm away from the sidewall of the
shielded room. Two 10kHz-30MHz, 50Ω/50uH Line-Impedance Stabilization Networks (LISNs) are
bonded to the shielded room floor. Power to the LISNs is filtered by external high-current
high-insertion loss power line filters. These filters attenuate ambient signal noise from entering the
measurement lines. These filters are also bonded to the shielded enclosure.
The EUT is powered from one LISN and the support equipment is powered from the second LISN.
All interconnecting cables more than 1 meter were shortened to a 1 meter length by non-inductive
bundling (serpentine fashion) and draped over the back edge of the test table. All cables were at
least 40cm above the horizontal reference ground-plane. Power cables for support equipment were
routed down to the second LISN while ensuring that that cables were not draped over the second
LISN.
Sufficient time for the EUT, support equipment, and test equipment was allowed in order for them to
warm up to their normal operating condition. The RF output of the LISN was connected to the
receiver and exploratory measurements were made to determine the frequencies producing the
maximum emission from the EUT. The receiver was scanned from 150kHz to 30MHz. The detector
function was set to peak mode for exploratory measurements while the bandwidth of the analyzer
was set to 9kHz. The EUT, support equipment, and interconnecting cables were arranged and
manipulated to maximize each emission. Each emission was also maximized by varying: power lines,
the mode of operation or data exchange speed, or support equipment whichever determined the
worst-case emission. Once the worst case emissions have been identified, the one EUT cable
configuration/arrangement and mode of operation that produced these emissions are used for final
measurements on the same test site. The analyzer is set to CISPR quasi-peak and average
detectors with a 9kHz resolution bandwidth for final measurements.
An extension cord was used to connect to a single LISN which powered by EUT. The extension cord
was calibrated with LISN, the impedance and insertion loss are compliance with the requirements as
stated in ANSI C63.10-2013.

3.3. Radiated Emissions
The radiated test facilities consisted of an indoor 3 meter semi-anechoic chamber used for final
measurements and exploratory measurements, when necessary. The measurement area is
contained within the semi-anechoic chamber which is shielded from any ambient interference. For
measurements above 1GHz absorbers are arranged on the floor between the turn table and the
antenna mast in such a way so as to maximize the reduction of reflections. For measurements below
1GHz, the absorbers are removed. A MF Model 210SS turntable is used for radiated measurement.
It is a continuously rotatable, remotecontrolled, metallic turntable and 2 meters (6.56 ft.) in diameter.
The turn table is flush with the raised floor of the chamber in order to maintain its function as a
ground plane. An80cm high PVC support structure is placed on top of the turntable.
For all measurements, the spectrum was scanned through all EUT azimuths and from 1 to 4 meter
receive antenna height using a broadband antenna from 30MHz up to the upper frequency shown in
15.33(b)(1) depending on the highest frequency generated or used in the device or on which the
device operates or tunes. For frequencies above 1GHz, linearly polarized double ridge horn
antennas were used. For frequencies below 30MHz, a calibrated loop antenna was used. When
exploratory measurements were necessary, they were performed at 1 meter test distance inside the
semi-anechoic chamber using broadband antennas, broadband amplifiers, and spectrum analyzers
to determine the frequencies and modes producing the maximum emissions. Sufficient time for the
EUT, support equipment, and test equipment was allowed in order for them to warm up to their
normal operating condition. The test set-up for frequencies below 1GHz was placed on top of the 0.8
meter high, 1 x 1.5 meter table; and test set-up for frequencies 1-40GHz was placed on top of the 1.5
meter high, 1 x 1.5 meter table. The EUT, support equipment, and interconnecting cables were
arranged and manipulated tomaximize each emission. Appropriate precaution was taken to ensure
that all emissions from the EUT were maximized and investigated. The system configuration, clock
speed, mode of operation or video resolution, if applicable, turntable azimuth, and receive antenna
height was noted for each frequency found.
Final measurements were made in the semi-anechoic chamber using calibrated, linearly polarized
broadband and horn antennas. The test setup was configured to the setup that produced the worst
case emissions. The spectrum analyzer was set to investigate all frequencies required for testing to
compare the highest radiated disturbances with respect to the specified limits. The turntable
containing the EUT was rotated through 360 degrees and the height of the receive antenna was
varied 1 to 4 meters and stopped at the azimuth and height producing the maximum emission. Each
emission was maximized by changing the orientation of the EUT through three orthogonal planes
and changing the polarity of the receive antenna, whichever produced the worst-case emissions.
According to 3dB Beam-Width of horn antenna, the horn antenna should be always directed to the
EUT when rising height.

7.6.2.Test Procedure Used
Frequency Stability Under Temperature Variations:
The equipment under test was connected to an external AC or DC power supply and input rated
voltage. RF output was connected to a frequency counter or spectrum analyzer via feed through
attenuators. The EUT was placed inside the temperature chamber. Set the spectrum analyzer RBW
low enough to obtain the desired frequency resolution and measure EUT 20°C operating frequency
as reference frequency. Turn EUT off and set the chamber temperature to highest. After the
temperature stabilized for approximately 30 minutes recorded the frequency. Repeat step measure
with 10°C decreased per stage until the lowest temperature reached.
Frequency Stability Under Voltage Variations:
Set chamber temperature to 20°C. Use a variable AC power supply / DC power source to power the
EUT and set the voltage to rated voltage. Set the spectrum analyzer RBW low enough to obtain the
desired frequency resolution and recorded the frequency.
Reduce the input voltage to specify extreme voltage variation (±15%) and endpoint, recordthe
maximum frequency change.

Report No.: 1710TW0108-U7
Refer to KDB 789033 D02v02r01 G)2)c), as specified in § 15.407(b), emissions above 1000 MHz
that are outside of the restricted bands are subject to a maximum emission limit of -27 dBm/MHz (or
-17 dBm/MHz as specified in § 15.407(b)(4)). However, an out-of-band emission that complies with
both the peak and average limits of § 15.209 is not required to satisfy the -27 dBm/MHz or -17
dBm/MHz maximum emission limit.
All out of band emissions appearing in a restricted band as specified in Section 15.205 of the Title
47CFR must not exceed the limits shown in Table per Section 15.209.

Average Measurements above 1GHz (Method VB)
1. Analyzer center frequency was set to the frequency of the radiated spurious emission of interest
2. RBW = 1MHz
3. VBW If the EUT is configured to transmit with duty cycle ≥ 98%, set VBW ≤ RBW/100 (i.e., 10 kHz)
but not less than 10 Hz. If the EUT duty cycle is < 98%, set VBW ≥ 1/T.
4. Detector = Peak
5. Sweep time = auto
6. Allow max hold to run for at least 50 traces if the transmitted signal is continuous or has at least 98%
duty cycle.
For lower duty cycles, increase the minimum number of traces by a factor of 1/x, where
x is the duty cycle.

7.9.2. Test Procedure
The EUT was setup according to ANSI C63.4, 2009 and tested according to KDB 789033 for
compliance to FCC 47CFR 15.247 requirements.The EUT was placed on a platform of nominal size,
1 m by 1.5 m, raised 80 cm above the conducting ground plane. The vertical conducting plane was
located 40 cm to the rear of the EUT. All other surfaces of EUT were at least 80 cm from any other
grounded conducting surface. The EUT and simulators are connected to the main power through a
line impedance stabilization network (LISN). The LISN provides a 50 ohm /50uH coupling
impedance for the measuring equipment. The peripheral devices are also connected to the main
power through a LISN. (Please refer to the block diagram of the test setup and photographs)Each
current-carrying conductor of the EUT power cord, except the ground (safety) conductor, was
individually connected through a LISN to the input power source.
The excess length of the power cord between the EUT and the LISN receptacle were folded back
and forth at the center of the lead to form a bundle not exceeding 40 cm in length.
Conducted emissions were investigated over the frequency range from 0.15MHz to 30MHz using a
receiver bandwidth of 9kHz.
