5.1. Antenna requirement
REQUIREMENT:
FCC CFR Title 47 Part 15 Subpart C Section 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 anantenna
that uses a unique coupling to the intentional radiator, 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.
FCC CFR Title 47 Part 15 Subpart C Section 15.247(c) (1)(i):
(i) Systems operating in the 2400~2483.5 MHz band that is used exclusively for fixed. Point-to-point
operations may employ transmitting antennas with directional gain greater than 6 dBi provided the maximum
conducted output power of the intentional radiator is reduced by 1 dB for every 3 dB that the directional gain
of the antenna exceeds 6 dBi.

Not Applicable
The directional gain of the antenna less than 6 dBi, please refer to the below antenna photo.

TEST CONFIGURATION
TEST PROCEDURE
1. The EUT was setup according to ANSI C63.10:2013 requirements.
2. 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.
3. The EUT and simulators are connected to the main power through a line impedances stabilization
network (LISN). The LISN provides a 50 ohm /50uH coupling impedance for the measuring equipment.
4. 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)
5. 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.
6. 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.
7. Conducted Emissions were investigated over the frequency range from 0.15MHz to 30MHz using a
receiver bandwidth of 9 kHz.
8. During the above scans, the emissions were maximized by cable manipulation.

3. Place the radio in continuous transmit mode, allow the trace to stabilize, view the transmitter wave form
on the spectrum analyzer.
4. Use the peak marker function to determine the maximum amplitude level within the RBW.
5. If measured value exceeds limit, reduce RBW (no less than 3 kHz) and repeat.

5.5. 6dB bandwidth
LIMIT
FCC CFR Title 47 Part 15 Subpart C Section 15.247 (a)(2):
For digital modulation systems, the minimum 6 dB bandwidth shall be at least 500 kHz.
TEST CONFIGURATION
TEST PROCEDURE
1. Connect the antenna port(s) to the spectrum analyzer input.
2. Configure the spectrum analyzer as shown below (enter all losses between the transmitter output and the
spectrum analyzer).
Center Frequency =DTS channel center frequency
Span=2 x DTS bandwidth
RBW = 100 kHz, VBW ≥ 3 × RBW
Sweep time= auto couple
Detector = Peak
Trace mode = max hold
3. Place the radio in continuous transmit mode, allow the trace to stabilize, view the transmitter wave form
on the spectrum analyzer.
4. Measure the maximum width of the emission that is constrained by the frequencies associated with the
two outermost amplitude points (upper and lower frequencies) that are attenuated by 6 dB relative to the
maximum level measured in the fundamental emission, and record the pertinent measurements.

5.6. Restricted band
LIMIT
FCC CFR Title 47 Part 15 Subpart C Section 15.247 (d):
In any 100 kHz bandwidth outside the frequency band in which the spread spectrum or digitally modulated
intentional radiator is operating, Radiated Emissions which fall in the restricted bands, as defined in
§15.205(a), must also comply with the Radiated Emissions limits specified in §15.209(a) (see §15.205(c)).
TEST CONFIGURATION
TEST PROCEDURE
1)
The EUT was setup and tested according to ANSI C63.10:2013 for compliance to FCC 47CFR 15.247
requirements.
2) The EUT is placed on a turn table which is 1.5 meter above ground. The turn table is rotated 360 degrees
to determine the position of the maximum emission level.
3) The EUT waspositioned such that the distance from antenna to the EUT was 3 meters.
4) The antenna is scanned from 1 meter to 4 meters to find out the maximum emission level. Thisis
repeated for both horizontal and vertical polarization of the antenna. In order to find themaximum
emission, all of the interface cables were manipulated according to ANSI C63.10:2013 on radiated
measurement.
5) The receiver set as follow:
RBW=1MHz, VBW=3MHz PEAK detector for Peak value.
RBW=1MHz, VBW=3MHz RMS detector for Average value.
TEST MODE:
Please refer to the clause 3.3
