CERPASS TECHNOLOGY CORP. Report No.: DEFI1606148 4. Antenna Requirements 4.1 Standard Applicable For intentional device, according to FCC 47 CFR Section 15.203, an intentional radiator shall be designed to ensure that no antenna other than that furnished by the responsible party shall be used with the device. And according to FCC 47 CFR Section 15.247(b), if transmitting antennas of directional gain greater than 6dBi are used, the power shall be reduced by the amount in dB that the directional gain of the antenna exceeds 6dBi. 4.2 Antenna Construction and Directional Gain No. Antenna Type Antenna Gain PCB Antenna 0.5dBi CERPASS TECHNOLOGY CORP. Issued date : Jul. 25, 2016 Page No. : 9 of 24 FCC ID : 2AAV8QH-X

CERPASS TECHNOLOGY CORP. Report No.: DEFI1606148 5. Test of Radiated Emission 5.1 Test Limit According to 15.231(e) the field strength of emissions from intentional radiators operated under these frequencies bands shall not exceed the following: Field Strength of Fundamental Field Strength of Spurious Frequency (MHz) μV/ m μV/ m 40.66 ~ 40.70 2250 225 70 ~130 1250 125 130 ~ 174 1250 ~ 3750 125 ~ 375 174 ~ 260 3750 375 260 ~ 470 3750~ 12500 375~ 1250 Above 470 12500 1250 NOTE: 1. Where F is the frequency in MHz, the formula for calculating the maximum permitted fundamental field strengths are as follows: for the band 130-174 MHz, uV/m at 3 meters = 56.81818(F) - 6136.3636; for the band 260-470 MHz, uV/m at 3 meters = 41.6667(F) - 7083.3333. The maximum permitted unwanted emission level is 20 dB below the maximum permitted fundamental level. 2. The above field strength limits are specified at a distance of 3meters. The tighter limits apply at the band edges. Emissions radiated outside of the specified bands, shall be according to the general radiated limits in 15.209 as following: Frequency (MHz) Distance Limit (μV/ m) 0.09 ~ 0.490 300m 2400/F(kHz) 0.490 ~ 1.705 30m 24000/ F(kHz) 1.705 ~ 30 30m 30 30 ~ 88 3m 100 88 ~ 216 3m 150 216 ~ 960 3m 200 Above 960 3m 500 As shown in 15.35(b), 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.

CERPASS TECHNOLOGY CORP. Report No.: DEFI1606148 5.2 Test Procedures a. The EUT was placed on a rotatable table top 0.8 meter above ground. b. The EUT was set 3 meters from the interference receiving antenna which was mounted on the top of a variable height antenna tower. c. The table was rotated 360 degrees to determine the position of the highest radiation. d. The antenna is a broadband antenna and its height is varied between one meter and four meters above ground to find the maximum value of the field strength both horizontal polarization and vertical polarization of the antenna are set to make the measurement. e. For each suspected emission the EUT was arranged to its worst case and then tune the antenna tower (from 1 M to 4 M) and turn table (from 0 degree to 360 degrees) to find the maximum reading. f. Set the test-receiver system to Peak or CISPR quasi-peak Detect Function and specified bandwidth with Maximum Hold Mode. g. If the emission level of the EUT in peak mode was 3 dB lower than the limit specified, then testing will be stopped and peak values of EUT will be reported, otherwise, the emissions which do not have 3 dB margin will be repeated one by one using the quasi-peak method and reported. h. For testing above 1GHz, the emission level of the EUT in peak mode was 20dB lower than average limit (that means the emission level in peak mode also complies with the limit in average mode), then testing will be stopped and peak values of EUT will be reported, otherwise, the emissions will be measured in average mode again and reported. i. “Cone of radiation” has been considered to be 3dB beamwidth of the measurement antenna. NOTE: 1. The resolution bandwidth and video bandwidth of test receiver/spectrum analyzer is 120kHz for Peak detection (PK) and Quasi-peak detection (QP) at frequency below 1GHz. 2. The resolution bandwidth and video bandwidth of test receiver/spectrum analyzer is 1 MHz for Peak detection at frequency above 1GHz. 3. The Average value = Peak value + 20log(Duty cycle) 4. Duty Factor = 20log(total duty / period of pulse train) NATA& PLOT: Number of Data Transmissions pulses Packet time 25.20 msec Long pulse Duration 1.05 msec 19 Short pulse Duration 0.33 msec 35 Total Transmissions Duration 1.05*19+0.33*35=31.5 msec On Time within 100 msec 31.5 msec Dutycycle Correction factor 20log(31.5/100)=-10.03dB CERPASS TECHNOLOGY CORP.
