NOTE: 1.The lower limit shall apply at the transition frequencies.
2.The limit decreases linearly with the logarithm of the frequency in the range
0,15 MHz to 0,50 MHz.
4.1.2. Test Procedure
1.The EUT was put on a wooden table which was 0.8 m high above the ground and connected to
the AC mains through the Artificial Mains Network (AMN). Where the mains cable supplied by
the manufacture was longer than 0.8 m, the excess was folded back and forth parallel to the
cable at the center so as to form a bundle no longer than 0.4 m.
2.The EUT was kept 0.4 m from any other earthed conducting surface. Both sides of AC line
were checked to find out the maximum conducted emission levels according to the test
procedure during the conducted emission test.
3.The frequency range from 150 kHz to 30 MHz was investigated.
4.The bandwidth of the test receiver was set at 9 kHz.
5.Pretest for all mode, the test data of the worst case condition(s) was reported on the following
page.

4.2.3. Test Procedure
The EUT was placed on a turn table which was 0.8 m(above 1GHz, the table was 1.5m) above
the ground. The turn table can rotate 360 degrees to determine the position of the maximum
emission level. The EUT was set 3 m away from the receiving antenna which was mounted on an
antenna tower. The measuring antenna moved up and down to find out the maximum emission
level. It moved from 1 m to 4 m for both horizontal and vertical polarizations.
The EUT was tested in the Chamber Site. It was pre-scanned with a Peak detector from the
spectrum, and all the final readings from the test receiver were measured with the Quasi-Peak
detector.
The bandwidth of the EMI test receiver is set at 120kHz for frequency range from 30MHz to 1000
MHz.
The bandwidth of the Spectrum’s VBW is set at 3MHz and RBW is set at 1MHz for peak
emissions measurement above 1GHz and 1MHz RBW, 10Hz VBW for average emissions
measure above 1GHz, Both PK and AV measure, PK detector is used.
The frequency range from 30MHz to 10th harmonic (25GHz) are checked. and no any emissions
were found from 18GHz to 25 GHz, So the radiated emissions from 18GHz to 25GHz were not
record.
Notes: 1. Emission Level = Antenna Factor + Cable Loss + Meter Reading-Preamp Factor.
2. Measurement Uncertainty: ±3.2 dB at a level of confidence of 95%.
3. For emissions above 1GHz, if peak level comply with average limit, then the average
level is deemed to comply with average limit.
4. For emissions below 1GHz, pretest for all mode, The test data of the worst case
condition(s) was reported on the following pages.
5. For Both PK and AV value above 1GHz, PK detector is used.
6. EUT Pre-scan X/Y/Z orientation, only worst case is presented in the report (Z
orientation).

5. BAND EDGE COMPLIANCE TEST
5.1. Limits
For FCC ID:
All the lower and upper band-edges emissions appearing within 2310MHz to 2390MHz and
2483.5MHz to 2500MHz restricted frequency bands shall not exceed the limits shown in 15.209,
all the other emissions outside operation frequency band 2400MHz to 2483.5MHz shall be at
least 30dB below the fundamental emissions, or comply with 15.209 limits.
For IC ID:
In any 100 kHz bandwidth outside the frequency band in which the spread spectrum or digitally
modulated device is operating, the RF power that is produced shall be at least 20dB 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, provided that the transmitter
demonstrates compliance with the peak conducted power limits. If the transmitter complies with
the conducted power limits based on the use of root-mean-square averaging over a time
interval, as permitted under Section 5.4(4), the attenuation required shall be 30dB instead of
20dB. Attenuation below the general field strength limits specified in RSS-Gen is not required.

The EUT was placed on a styrofoam table which is 1.5m above ground plane.
The measurement procedure at the ban edges was simplified by performing the
measurement in just one plot. Both, the in-band-emission and the unwanted emission
were be encompassed by the span. After trace stabilization, the maxium peak was be
determined by a peak detector and the value was marked by an appropriate limit line.
The second limit line, which is 20dB below the first, marks the limits for the emissions
in the unrestricted band next to the band edge.

The measurements were performed at the lower end of the 2.4GHz band.
