Test Setting Average power measurements were performed 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. 6.5.4. Test Setup 6.5.5.

Test Limit For the band 5.15-5.25 GHz, the maximum power spectral density shall not exceed 17 dBm in any 1 megahertz band. For the 5.25-5.35 GHz and 5.47-5.725 GHz bands, the maximum power spectral density shall not exceed 11 dBm in any 1 megahertz band. For the band 5.725-5.85 GHz, the maximum power spectral density shall not exceed 30 dBm in any 500-kHz band. If transmitting antennas of directional gain greater than 6dBi are used, the peak power spectral density shall be reduced by the amount in dB that the directional gain of the antenna exceeds 6dBi. 6.6.2. Test Procedure KDB 789033 D02v02r01-Section II)F) 6.6.3. Test Setting 1. Analyzer was set to the center frequency of the UNII channel under investigation 2. Span was set to encompass the entire 26dB EBW of the signal. 3. RBW = 1MHz (510kHz, if measurement bandwidth of Maximum PSD is specified in 500 kHz) 4. VBW = 3 × RBW 5. Number of sweep points 2 × (span / RBW) 6. Detector = power averaging (Average) 7. Sweep time = auto 8. Trigger = free run 9. Trace average at least 100 traces in power averaging (rms) mode; however, the number of traces to be averaged shall be increased above 100 as needed to ensure that the average accurately represents the true average over the on and off periods of the transmitter. 10. Use the peak search function on the instrument to find the peak of the spectrum and record its value. 11. Add 10*log(1/x), where x is the duty cycle, to the measured power in order to compute the average power during the actual transmission times (because the measurement represents an average over both the on and off times of the transmission). For example, add 10*log(1/0.25) = 6 dB if the duty cycle is 25 percent. 21 of 284 6.6.4. Test Setup 6.6.5. Test Result Refer to Appendix A.5.

Test Limit Manufactures of U-NII devices are responsible for ensuring frequency stability such that an emission is maintained within the band of operation under all conditions of normal operation as specified in the user's manual. 6.7.2. Test Procedure Frequency Stability Under Temperature Variations: The equipment under test was connected to an external AC or DC power supply and input rated voltage. RF output was connected to a frequency counter or spectrum analyzer via feed through attenuators. The EUT was placed inside the temperature chamber. Set the spectrum analyzer RBW low enough to obtain the desired frequency resolution and measure EUT 20°C operating frequency as reference frequency. Turn EUT off and set the chamber temperature to highest. After the temperature stabilized for approximately 30 minutes recorded the frequency. Repeat step measure with 10°C decreased per stage until the lowest temperature reached. Frequency Stability Under Voltage Variations: Set chamber temperature to 20°C. Use a variable AC power supply / DC power source to power the EUT and set the voltage to rated voltage. Set the spectrum analyzer RBW low enough to obtain the desired frequency resolution and recorded the frequency. Reduce the input voltage to specify extreme voltage variation (±15%) and endpoint, recordthe maximum frequency change. 6.7.3. Test Setup 23 of 284 6.7.4. Test Result Refer to Appendix A.6.
