Appendix F): Antenna Requirement
15.203 requirement:
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, 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.
15.247(b) (4) requirement:
The conducted output power limit specified in paragraph (b) of this section is based on the use of antennas
with directional gains that do not exceed 6 dBi. Except as shown in paragraph (c) of this section, if
transmitting antennas of directional gain greater than 6 dBi are used, the conducted output power from the
intentional radiator shall be reduced below the stated values in paragraphs (b)(1), (b)(2), and (b)(3) of this
section, as appropriate, by the amount in dB that the directional gain of the antenna exceeds 6 dBi.
EUT Antenna:
The antenna is PIFA Antenna and no consideration of replacement. The best case gain of the 2.4G WiFi
antenna is 2.72dBi.

Appendix G): AC Power Line Conducted Emission
Test Procedure:
Test frequency range :150KHz-30MHz
1)The mains terminal disturbance voltage test was conducted in a shielded room.
2) The EUT was connected to AC power source through a LISN 1 (Line Impedance
Stabilization Network) which provides a 50Ω/50µH + 5Ω linear impedance. The
power cables of all other units of the EUT were connected to a second LISN 2,
which was bonded to the ground reference plane in the same way as the LISN 1 for
the unit being measured. A multiple socket outlet strip was used to connect multiple
power cables to a single LISN provided the rating of the LISN was not
exceeded.
3)The tabletop EUT was placed upon a non-metallic table 0.8m above the ground
reference plane. And for floor-standing arrangement, the EUT was placed on the
horizontal ground reference plane,
4) The test was performed with a vertical ground reference plane. The rear of the EUT
shall be 0.4 m from the vertical ground reference plane. The vertical ground
reference plane was bonded to the horizontal ground reference plane. The LISN 1
was placed 0.8 m from the boundary of the unit under test and bonded to a ground
reference plane for LISNs mounted on top of the ground reference plane. This
distance was between the closest points of the LISN 1 and the EUT. All other units
of the EUT and associated equipment was at least 0.8 m from the LISN 2.
5) In order to find the maximum emission, the relative positions of equipment and all of
the interface cables must be changed according to ANSI C63.10 on conducted
measurement.

An initial pre-scan was performed on the live and neutral lines with peak detector.
Quasi-Peak and Average measurement were performed at the frequencies with maximized peak emission were
detected.

Test Procedure:
Below 1GHz test procedure as below:
a. The EUT was placed on the top of a rotating table 0.8 meters above the ground
at a 3 meter semi-anechoic camber. The table was rotated 360 degrees to
determine the position of the highest radiation.
b. The EUT was set 3 meters away from the interference-receiving antenna, which
was mounted on the top of a variable-height antenna tower.
c. The antenna height is varied from one meter to four meters above the ground to
determine the maximum value of the field strength. Both horizontal and vertical
polarizations of the antenna are set to make the measurement.
d. For each suspected emission, the EUT was arranged to its worst case and then
the antenna was tuned to heights from 1 meter to 4 meters and the rotatable
was turned from 0 degrees to 360 degrees to find the maximum reading.
e. The test-receiver system was set to Peak Detect Function and Specified
Bandwidth with Maximum Hold Mode.
f. Place a marker at the end of the restricted band closest to the transmit
frequency to show compliance. Also measure any emissions in the restricted
bands. Save the spectrum analyzer plot. Repeat for each power and modulation
for lowest and highest channel
Above 1GHz test procedure as below:
g. Different between above is the test site, change from Semi- Anechoic Chamber
to fully Anechoic Chamber change form table 0.8 meter to 1.5 meter( Above
18GHz the distance is 1 meter and table is 1.5 meter).
h. Test the EUT in the lowest channel , the Highest channel
i. The radiation measurements are performed in X, Y, Z axis positioning for
Transmitting mode, and found the X axis positioning which it is worse case.
j. Repeat above procedures until all frequencies measured was complete.

Note:
1) Through Pre-scan transmitting mode and with all kind of modulation and data rate, find the 11Mbps of rate is
the worst case of 802.11b; 6Mbpsof rate is the worst case of 802.11g; 6.5Mbps of rate is the worst case of
802.11n(HT20) ; 13.5Mbps of rate is the worst case of 802.11n(HT40),and then Only the worst case is recorded
in the report.
2) The field strength is calculated by adding the Antenna Factor, Cable Factor & Preamplifier. The basic
equation with a sample calculation is as follows:
Final Test Level =Receiver Reading - Correct Factor
Correct Factor = Preamplifier Factor– Antenna Factor–Cable Factor
3) All modes and antenna are tested, and found the antenna 1 which is worst case, and then only the worst
case mode is recorded in the report.

Test Procedure:
Below 1GHz test procedure as below:
a. The EUT was placed on the top of a rotating table 0.8 meters above the ground at a 3 meter semi-anechoic
camber. The table was rotated 360 degrees to determine the position of the highest radiation.
b. The EUT was set 3 meters away from the interference-receiving antenna, which was mounted on the top of a
variable-height antenna tower.
c. The antenna height is varied from one meter to four meters above the ground to determine the maximum value
of the field strength. Both horizontal and vertical polarizations of the antenna are set to make the measurement.
d. For each suspected emission, the EUT was arranged to its worst case and then the antenna was tuned to
heights from 1 meter to 4 meters (for the test frequency of below 30MHz, the antenna was tuned to heights 1
meter) and the rotatable was turned from 0 degrees to 360 degrees to find the maximum reading.
e. The test-receiver system was set to Peak Detect Function and Specified Bandwidth with Maximum Hold Mode.
f. If the emission level of the EUT in peak mode was 10dB lower than the limit specified, then testing could be
stopped and the peak values of the EUT would be reported. Otherwise the emissions that did not have 10dB
margin would be re-tested one by one using peak, quasi-peak or average method as specified and then reported
in a data sheet.
Above 1GHz test procedure as below:
g. Different between above is the test site, change from Semi- Anechoic Chamber to fully Anechoic Chamber and
change form table 0.8 meter to 1.5 meter( Above 18GHz the distance is 1 meter and table is 1.5 meter)..
h. Test the EUT in the lowest channel ,the middle channel ,the Highest channel
i. The radiation measurements are performed in X, Y, Z axis positioning for Transmitting mode, and found the X
axis positioning which it is worse case.
j. Repeat above procedures until all frequencies measured was complete.

1) Through Pre-scan transmitting mode with all kind of modulation and data rate, find the 11Mbps of rate is the
worst case of 802.11b; 6Mbpsof rate is the worst case of 802.11g; 6.5Mbps of rate is the worst case of
802.11n(HT20) ; 13.5Mbps of rate is the worst case of 802.11n(HT40),and then Only the worst case is recorded
in the report.
2) The field strength is calculated by adding the Antenna Factor, Cable Factor & Preamplifier. The basic
equation with a sample calculation is as follows:
Final Test Level =Receiver Reading - Correct Factor
Correct Factor = Preamplifier Factor– Antenna Factor–Cable Factor
3) Scan from 9kHz to 25GHz, the disturbance above 13GHz and below 30MHz was very low, and the above
harmonics were the highest point could be found when testing, so only the above harmonics had been
displayed. The amplitude of spurious emissions from the radiator which are attenuated more than 20dB below
the limit need not be reported.
4) All modes and antenna are tested, and found the antenna 1 which is worst case, and then only the worst
case mode is recorded in the report.
