Note:
1. All of modulation mode support beamforming function except 802.11a/b/g modulation mode.
3. The modulation and bandwidth are similar for 802.11n mode for 20MHz (40MHz) and 802.11ac mode for
20MHz (40MHz), therefore investigated worst case to representative mode in test report. (Final test mode
refer section 3.2.1)
7. The above EUT information is declared by manufacturer and for more detailed features description,
   please refer to the manufacturer's specifications or user's manual.

NOTE:
1.       The lower limit shall apply at the transition frequencies.
2.       Emission level (dBuV/m) = 20 log Emission level (uV/m).
3.       For frequencies above 1000MHz, the field strength limits are based on average detector, however, the
         peak field strength of any emission shall not exceed the maximum permitted average limits, specified
         above by more than 20dB under any condition of modulation.

4.1.3 Test Procedures
For Radiated emission below 30MHz
 a. The EUT was placed on the top of a rotating table 0.8 meters above the ground at a 3 meter chamber
        room. 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. Both X and Y axes of the antenna are set to make the measurement.

     d. For each suspected emission, the EUT was arranged to its worst case and the rotatable table was turned
        from 0 degrees to 360 degrees to find the maximum reading.

     e. The test-receiver system was set to Quasi-Peak Detect Function and Specified Bandwidth with
        Maximum Hold Mode.
NOTE:
     1. The resolution bandwidth and video bandwidth of test receiver/spectrum analyzer is 9kHz at frequency
        below 30MHz.

For Radiated emission above 30MHz
a. The EUT was placed on the top of a rotating table 0.8 meters (for 30MHz ~ 1GHz) / 1.5 meters (for above
    1GHz) above the ground at 3 meter chamber room for test. 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 height of antenna 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 table was turned from 0 degrees to 360 degrees to
        find the maximum reading.
e.      The test-receiver system was set to quasi-peak detect function and specified bandwidth with maximum
        hold mode when the test frequency is below 1 GHz.
f.      The test-receiver system was set to peak and average detect function and specified bandwidth with
        maximum hold mode when the test frequency is above 1 GHz. If the peak reading value also meets
        average limit, measurement with the average detector is unnecessary.


Note:
1. The resolution bandwidth and video bandwidth of test receiver/spectrum analyzer is 120kHz for
    Quasi-peak detection (QP) at frequency below 1GHz.
2.      The resolution bandwidth of test receiver/spectrum analyzer is 1 MHz and the video bandwidth is 3 MHz
        for Peak detection (PK) at frequency above 1GHz.
3.      The resolution bandwidth of test receiver/spectrum analyzer is 1MHz and the video bandwidth is ≥ 1/T
        (Duty cycle < 98%) or 10Hz (Duty cycle ≥ 98%) for Average detection (AV) at frequency above 1GHz.
4.      All modes of operation were investigated and the worst-case emissions are reported.

4.2.3    Test Procedures

  a. The EUT was placed 0.4 meters from the conducting wall of the shielded room with EUT being
     connected to the power mains through a line impedance stabilization network (LISN). Other support
     units were connected to the power mains through another LISN. The two LISNs provide 50 ohm/ 50uH
     of coupling impedance for the measuring instrument.
  b. Both lines of the power mains connected to the EUT were checked for maximum conducted
     interference.
  c.    The frequency range from 150kHz to 30MHz was searched. Emission levels under (Limit - 20dB) was
        not recorded.

 NOTE: The resolution bandwidth and video bandwidth of test receiver is 9kHz for quasi-peak detection (QP)
       and average detection (AV) at frequency 0.15MHz-30MHz.


4.2.4    Deviation from Test Standard
