FCC Statement This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to Part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a residential installation. This equipment generates, uses and can radiate radio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful interference to radio communications. However, there is no guarantee that interference will not occur in a particular installation. If this equipment does cause harmful interference to radio or television reception, which can be determined by turning the equipment off and on, the user is encouraged to try to correct the interference by one of the following measures: Reorient or relocate the receiving antenna. Increase the separation between the equipment and receiver. Connect the equipment into an outlet on a circuit different from that to which the receiver is connected. Consult the dealer or an experienced radio/TV technician for help. To assure continued compliance, any changes or modi�ications not expressly approved by the party responsible for compliance could void the user's authority to operate this equipment. FCC Radiation Exposure Statement This equipment complies with FCC RF radiation exposure limits set forth for an uncontrolled environment. This equipment should be installed and operated with a minimum distance of centimeters between the radiator and your body. This device complies with Part 15 of the FCC Rules. Operation is subject to the following two conditions: (1) This device may not cause harmful interference, and (2) This device must accept any interference received, including interference that may cause undesired operation. This transmitter must not be co-located or operating in conjunction with any other antenna or transmitter. 957DFV00AD The device for operation in the band 5150-5250 MH is only for indoor use. z 24

The EUT supports Cyclic Delay Diversity (CDD) mode, and CDD signals are correlated. If all antennas have the same gain, G ANT , Directional gain = G ANT + Array Gain, where Array Gain is as follows. • For power spectral density (PSD) measurements on all devices, Array Gain = 10 log (N ANT / N SS ) dB; • For power measurements on IEEE 802.11 devices, Array Gain = 0 dB for N ANT ≤ 4; 2. The EUT also supports Beam Forming mode, and the Beam Forming support 802.11ac/ax, not include 802.11a/b/g/n. BF Directional gain = G ANT + 10 log (N ANT ). 3.

Test Procedure used KDB 789033 D02v02r01 - Section C.2 7.3.3. Test Setting 1. Set center frequency to the nominal EUT channel center frequency. 2. RBW = 100 kHz. 3. VBW ≧ 3 × RBW. 4. Detector = Peak. 5. Trace mode = max hold. 6. Sweep = auto couple. 7. Allow the trace to stabilize. 8. Measure the maximum width of the emission that is constrained by the frequencies associated with the two outermost amplitude points (upper and lower frequencies) that are attenuated by 6 dB relative to the maximum level measured in the fundamental emission. 7.3.4.

Output Power Measurement 7.4.1. Test Limit For client operating in the band 5.15-5.25 GHz, the maximum conducted output power over the frequency band of operation shall not exceed 250mW. For the 5.25-5.35 GHz and 5.47-5.725 GHz bands, the maximum conducted output power over the frequency bands of operation shall not exceed the lesser of 250 mW (23.98dBm) or 11dBm +10 log (26dB BW). For the band 5.725-5.85 GHz, the maximum conducted output power over the frequency band of operation shall not exceed 1 W (30dBm). If transmitting antennas of directional gain greater than 6dBi are used, the maximum conducted output power shall be reduced by the amount in dB that the directional gain of the antenna exceeds 6dBi. 7.4.2. Test Procedure Used KDB 789033 D02v02r01 - Section E) 3) b) Method PM-G eport No.: 2211TWD801-U2 FCC ID: P27OT4221 Page Number: 45 of 338 7.4.3. Test Setting Average power measurements were perform only when the EUT was transmitting at its maximum power control level using a broadband power meter with a pulse sensor. The power meter implemented triggering and gating capabilities which were set up such that power measurements were recorded only during the ON time of the transmitter. The trace was averaged over 100 traces to obtain the final measured average power. 7.4.4. Test Setup eport No.: 2211TWD801-U2 FCC ID: P27OT4221 Page Number: 46 of 338 7.4.5.
