2) FCC part 15C section 15.247(d)
3) FCC Part 15C section 15.205
4.6.2. Test procedure
The EUT was placed on a turn table which was 0.8 meter above ground. The turn table
can rotate 360 degrees to determine the position of the maximum emission level. The
EUT was set 3 meters away from the receiving antenna which was mounted on a antenna
tower. At the frequency band of 30MHz to 1GHz,The measuring antenna moved up and
down to find out the maximum emission level. It moved from 1 to 4 m for horizontal and
vertical polarizations. The broadband antenna (calibrated by dipole antenna) was used as
a receiving antenna. At the frequency band of 1GHz to 25GHz,The measuring antenna
moved from 1 to 4 m for horizontal and vertical polarization. The horn antenna was used
as a receiving antenna.

The resolution bandwidth and video bandwidth of the test receiver was 120 KHz and
300KHz for Quasi-peak detection at frequency below 1GHz.

The resolution bandwidth and video bandwidth of the test receiver was1MHz and 3MHz
for Peak detection at frequency above 1GHz.

For Average measurement at frequency above 1GHz.The resolution bandwidth of the test
receiver was 1MHz ; due to the shortest pulse width T is 116us, according the video bandwidth
should not smaller than 1/T,so the video bandwidth is 10kHz.

The EUT was tested in Chamber Site.

Notes: 1. The readings were Quasi-Peak values below 1GHz.
The readings were Peak values + Average values above1GHz
2. Emission Level = Antenna Factor + Cable Loss + Meter Reading
3. Test uncertainty: ±4.76dB at a level of confidence of 95%.
4. The frequency with * stands for carrier frequency.

4.7. Band edge test
4.71. Test limits
In any 100kHz bandwidth outside the frequency band in which the spread spectrum
intentional radiator is operating, the radio frequency power that is produce by the
intentional radiator shall be at least 20dB below that in 100kHz bandwidth within the band
that contains the highest level of the desired power.
4.7.2. Test procedure
1.The EUT was placed on a turntable which is 0.8m above ground plane.
2. Set EUT as continuous transmitting mode.
3. Set the EUT work on the CH1, CH79individually.
4. Set SPA Frequency = Operation frequency, for PK: RBW =100kHz, VBW≧RBW
5. Set SPA trace max hold, then view.

4.7.4. Test result
The spectrum plots are attached on the following 4 images. D1 line indicates
the highest level, D2 line indicates the 20dB offset below D1. It shows compliance
with the requirement in part 15.247(d).
Note 1: The band edge emission plot on page 27 shows 43.13dBc between carrier
maximum power and local maximum emission in restrict band(2.390GHz).The
emission of carrier strength list in the test result of channel 1 at the item 4.6.4 is
87.92dBuV/m (peak). So the maximum field strength in restrict band is 87.92-43.13
= 44.79dBuV/m, which is under 74dBuV/m limit.

Note 2: The band edge emission plot on page 28 shows 49.77dBc between carrier
maximum power and local maximum emission in restrict band(2.489GHz).The
emission of carrier strength list in the test result of channel 79 at the item 4.6.4 is
88.90dBuV/m (peak). So the maximum field strength in restrict band is 88.90-49.77
= 39.13dBuV/m, which is under 74dBuV/m limit.

4.8. Antenna requirement
4.8.1. Standard applicable
For intentional device, according to FCC 47 CFR 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. And according to FCC 47 CFR Section 15.247(b), if
transmitting antennas of directional gain greater than 6dBi are used, the power shall be
reduced by the amount in dB that the directional gain of the antenna exceeds 6dBi.

4.8.2.Antenna connected construction
The antenna used in this product is integrated antenna on the main PCB and no
consideration of replacement.
