2) Directional Gain Calculations for In-Band Measurements
a) Basic methodology with NANT transmit antennas, each with the same directional gain GAN
T dBi, being driven by NANT transmitter outputs of equal power. Directional gain is to be com
puted as follows:
(i) If any transmit signals are correlated with each other,
Directional gain = GANT + 10 log(NANT) dBi
(ii) If all transmit signals are completely uncorrelated with each other,
Directional gain = GANT
ANT A=1 dBi
ANT B=1dBi
GANT + 10 log(NANT) dBi
Directional gain= 1+10log2=4.01dBi

3.1.2 TEST PROCEDURE
a. The EUT was 0.8 meters from the horizontal ground plane and 0.4 meters from the vertical
ground plane with EUT being connected to the power mains through a line impedance
stabilization network (LISN). All other support equipments powered from additional LISN(s).
The LISN provide 50 Ohm/ 50uH of coupling impedance for the measuring instrument.
b. Interconnecting cables that hang closer than 40 cm to the ground plane shall be folded back
and forth in the center forming a bundle 30 to 40 cm long.
c. I/O cables that are not connected to a peripheral shall be bundled in the center. The end of the
cable may be terminated, if required, using the correct terminating impedance. The overall
length shall not exceed 1 m.
d. LISN at least 80 cm from nearest part of EUT chassis.
e. For the actual test configuration, please refer to the related Item –EUT Test Photos.

3.2.2 TEST PROCEDURE
a. The measuring distance of at 3 m shall be used for measurements at frequency 0.009MHz up
to 1GHz. For frequencies above 1GHz, any suitable measuring distance may be used.
b. The EUT was placed on the top of a rotating table 0.8 meters(above 1GHz is 1.5 m) above the
ground at a 3 meter anechoic chamber. The table was rotated 360 degrees to determine the
position of the highest radiation.
c. The height of the equipment shall be 0.8 m(above 1GHz is 1.5 m); the height of the test
antenna shall vary between 1 m to 4 m. Horizontal and vertical polarizations of the antenna
are set to make the measurement
d. The initial step in collecting conducted emission data is a spectrum analyzer peak detector
mode pre-scanning the measurement frequency range. Significant peaks are then marked and
then Quasi Peak detector mode re-measured.
e. If the Peak Mode measured value compliance with and lower than Quasi Peak Mode Limit, the
EUT shall be deemed to meet QP Limits and then no additional QP Mode measurement
performed.
f. For the actual test configuration, please refer to the related Item –EUT Test Photos.
Note:
Both horizontal and vertical antenna polarities were tested and performed test to three
orthogonal axis. The worst case emissions were reported

(B)Radiated Emission Test-Up Frequency 30MHz~1GHz
(C)Radiated Emission Test-Up Frequency Above 1GHz
3.2.4 EUT OPERATING CONDITIONS
The EUT tested system was configured as the statements of 2.3 Unless otherwise a special
operating condition is specified in the follows during the testing.
Page 21 of 65
Report No.: STS1708150W01
3.2.5 FIELD STRENGTH CALCULATION
The field strength is calculated by adding the Antenna Factor and Cable Factor and subtracting
the Amplifier Gain and Duty Cycle Correction Factor (if any) from the measured reading. The
basic equation with a sample calculation is as follows:
FS = RA + AF + CL - AG
Where
FS = Field Strength
CL = Cable Attenuation Factor (Cable Loss)
RA = Reading Amplitude
AG = Amplifier Gain
AF = Antenna Factor

2. Scan with 802.11b, 802.11g, 802.11n (HT-20), 802.11n (HT-40) all have been tested the antenna A and antenna B,
the worst case is 802.11b of the antenna A
Emission Level = Meter Reading + Factor; Margin = Limit - Emission Leve
4.The frequency emission of peak points that did not show above the forms are at least 20dB below the limit, the

Remark: Factor = Antenna Factor + Cable Loss – Pre-amplifier.
Low measurement frequencies is range from 2300 to 2412 MHz, high measurement frequencies is range from
2462 to 2500 MHz.
Only show the worst point data of the emissions in the frequency 2300-2412 MHz and 2462-2500 MHz.
802.11b , 802.11g: ANT A and ANT B all have been tested ,only worse case is reported

4. CONDUCTED SPURIOUS & BAND EDGE EMISSION
4.1 APPLIED PROCEDURES / LIMIT
According to FCC section 15.247(d), in any 100kHz 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 20dB below that in the 100kHz
bandwidth within the band that contains the highest level of the desired power, based on either an
RF conducted or a radiated measurement.

4.3 DEVIATION FROM STANDARD
No deviation.
4.4 TEST SETUP
The EUT which is powered by the Battery, is coupled to the Spectrum Analyzer; the RF load
attached to the EUT antenna terminal is 50Ohm; the path loss as the factor is calibrated to correct
the reading.
Make the measurement with the spectrum analyzer's resolution bandwidth (RBW) = 100 kHz. In
order to make an accurate measurement, set the span greater than RBW.
4.5 EUT OPERATION CONDITIONS
The EUT tested system was configured as the statements of 2.3 Unless otherwise a special operating
condition is specified in the follows during the testing.

5.2 TEST PROCEDURE
1. Set analyzer center frequency to DTS channel center frequency.
2. Set the span to 1.5 times the DTS channel bandwidth.
3. Set the 100 kHz ≥ RBW ≥ 3 kHz.
4. Set the VBW ≥ 3 x RBW.
5. Detector = peak.
6. Sweep time = auto couple.
7. Trace mode = max hold.
8. Allow trace to fully stabilize.
9. Use the peak marker function to determine the maximum amplitude level.
10. If measured value exceeds limit, reduce RBW (no less than 3 kHz) and repeat.

6.2 TEST PROCEDURE
The automatic bandwidth measurement capability of an instrument may be employed using the X
dB bandwidth mode with X set to 6 dB, if the functionality described above (i.e., RBW = 100 kHz,
VBW≥3RBW, peak detector with maximum hold) is implemented by the instrumentation function.
When using this capability, care shall be taken so that the bandwidth measurement is not
influenced by any intermediate power nulls in the fundamental emission that might be≥6 dB.
