Notes:
1. Measuring frequencies from 9 KHz~10th harmonic or 26.5GHz (which is less), No emission found
between lowest internal used/generated frequency to 30MHz.
2. Radiated emissions measured in frequency range from 9 kHz~10th harmonic or 26.5GHz (which is less)
were made with an instrument using Peak detector mode.
3. Data of measurement within this frequency range shown “---” in the table above means the reading of
emissions are attenuated more than 20dB below the permissible limits or the field strength is too small
to be measured.
4. Worst case data at 1Mbps at IEEE 802.11b; 6Mbps at IEEE 802.11g; 6.5Mbps at IEEE 802.11n HT20.

5.6. Conducted Spurious Emissions and Band Edges Test
5.6.1. Standard Applicable

According to §15.247 (d): 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. Attenuation below the general limits specified in Section 15.209(a) is not required. In
addition, radiated emissions which fall in the restricted bands, as defined in Section 15.205(a), must also
comply with the radiated emission limits specified in Section 15.209(a) (see Section 15.205(c)).

5.6.2. Measuring Instruments and Setting

Please refer to equipment list in this report. The following table is the setting of the spectrum analyzer.

Spectrum Parameter Setting
Detector Peak
Attenuation Auto
RB / VB (Emission in restricted band) 100KHz/300KHz
RB / VB (Emission in non-restricted band) 100KHz/300KHz

5.6.3. Test Procedures

The transmitter output is connected to a spectrum analyzer. The resolution bandwidth is set to 100 KHz.
The video bandwidth is set to 300 KHz
The spectrum from 9 KHz to 26.5 GHz is investigated with the transmitter set to the lowest, middle, and
highest channels.

5.6.4. Test Setup Layout

This test setup layout is the same as that shown in section 5.4.4.

5.6.5. EUT Operation during Test

The EUT was programmed to be in continuously transmitting mode.

5.6.6. Test Results of Conducted Spurious Emissions

PASS
Please refer to Appendix C RF Test Data for 2.4G WIFI Section C.5 for conducted spurious
emission;
Please refer to Appendix C RF Test Data for 2.4G WIFI Section C.6 for conducted band edge.
Remark:
1). Measured RF conducted spurious emission at difference data rate for each mode and recorded worst
case for each mode.
2). Test results including cable loss;
3). Worst case data at 1Mbps at IEEE 802.11b; 6Mbps at IEEE 802.11g; 6.5Mbps at IEEE 802.11n HT20;
4). “---“means that the fundamental frequency not for 15.209 limits requirement.
5). Not recorded emission from 9 KHz to 30 MHz as emission level at least 20dBc lower than emission
limit.

D = specified measurement distance in meters.
11). Since the out-of-band characteristics of the EUT transmit antenna will often be unknown, the use of a
conservative antenna gain value is necessary. Thus, when determining the EIRP based on the measured
conducted power, the upper bound on antenna gain for a device with a single RF output shall be selected
as the maximum in-band gain of the antenna across all operating bands, or 2 dBi, whichever is greater.
However, for devices that operate in multiple frequency bands while using the same transmit antenna, the
highest gain of the antenna within the operating band nearest in frequency to the restricted band emission
being measured may be used in lieu of the overall highest gain when the emission is at a frequency that is
within 20 percent of the nearest band edge frequency, but in no case shall a value less than 2 dBi be used.
12). Compare the resultant electric field strength level to the applicable regulatory limit.
13). Perform radiated spurious emission test duress until all measured frequencies were complete.

5.8.5 Test Results

PASS
Please refer to Appendix C RF Test Data for 2.4G WIFI Section C.7
Remark:
1). Measured Band edge measurement for radiated emission at difference data rate for each mode and
recorded worst case for each mode.
2). Test results including cable loss;
3). Worst case data at 1Mbps at IEEE 802.11b; 6Mbps at IEEE 802.11g; 6.5Mbps at IEEE 802.11n HT20;
4). “---“means that the fundamental frequency not for 15.209 limits requirement.

5.9. Antenna Requirements
5.9.1 Standard Applicable

According to antenna requirement of §15.203.

According to antenna requirement of §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 re-placed by the user, but the use of a standard antenna jack or
electrical connector is prohibited. This requirement does not apply to carrier current devices or to devices
operated under the provisions of Sections 15.211, 15.213, 15.217, 15.219, or 15.221. Further, this
requirement does not apply to intentional radiators that must be professionally installed, such as perimeter
protection systems and some field disturbance sensors, or to other intentional radiators which, in
accordance with Section 15.31(d), must be measured at the installation site. However, the installer shall
be responsible for ensuring that the proper antenna is employed so that the limits in this Part are not
exceeded.

And according to §15.247(4)(1), system operating in the 2400-2483.5MHz bands that are used
exclusively for fixed, point-to-point operations may employ transmitting antennas with directional gain
greater than 6dBi provided the maximum peak output power of the intentional radiator is reduced by 1 dB
for every 3 dB that the directional gain of the antenna exceeds 6dBi.

5.9.2 Antenna Connected Construction
5.9.2.1. Standard Applicable

According to § 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.

5.9.2.2. Antenna Connector Construction

The gain of antenna used for transmitting is 2.0dBi, and the antenna is a Ceramic antenna and no
consideration of replacement. Please see EUT photo for details.

5.9.2.3. Results: Compliance.
