Evaluation Method Systems operating under the provisions of FCC 47 CFR section shall be operated in a manner that ensures that the public is not exposed to radio frequency energy level in excess of the Commission’s guidelines. In accordance with 47 CFR FCC Part 2 Subpart J, section 2.1091 this device has been defined as mobile device whereby a distance of 0.2m normally can be maintained between the user and the device, and below RF Permissible Exposure limit shall comply with. In accordance with KDB447498D01 for Simultaneous transmission MPE test exclusion applies when the sum of the MPE ratios for all simultaneous transmitting antennas incorporated in a host device, based on the calculated/estimated, numerically modelled or measured field strengths or power density, is ≤ 1.0. The MPE ratio of each antenna is determined at the minimum test separation distance required by the operating configurations and exposure conditions of the host device, according to the ratio of field strengths or power density to MPE limit, at the test frequency. Either the maximum peak or spatially averaged results from measurements or numerical simulations may be used to determine the MPE ratios. Spatial averaging does not apply when MPE is estimated using simple calculations based on far-field plane-wave equivalent conditions. The antenna installation and operating requirements for the host device must meet the minimum test separation distances required by all antennas, in both standalone and simultaneous transmission operations, to satisfy compliance. 3.

Power line conducted emissions 5.7.1 Standard Applicable According to §15.207 (a): For an intentional radiator which is designed to be connected to the public utility (AC) power line, the radio frequency voltage that is conducted back onto the AC power line on any frequency or frequencies within the band 150 kHz to 30 MHz shall not exceed 250 microvolts (The limit decreases linearly with the logarithm of the frequency in the range 0.15 MHz to 0.50 MHz). The limits at specific frequency range are listed as follows: Frequency Range (MHz) Limits (dBμV) Quasi-peak Average 0.15 to 0.50 66 to 56 56 to 46 0.50 to 5 56 46 5 to 30 60 50 * Decreasing linearly with the logarithm of the frequency 5.7.2 Block Diagram of Test Setup PC LISN EMI receiver Reference ground plane Vert. reference plane EUT 5.7.3 Test Results The Worst Test result for 802.11b (Low Channel) Temperature 22.8°C Humidity 60% Test Engineer Anna Hu Configurations 802.11b (Low Channel) Report No.: TZ201101788-E Page 60 of 67 AC Conducted Emission of power adapter @ AC 120V/60Hz @ IEEE 802.11b Middle Channel (worst case) Line Report No.: TZ201101788-E Page 61 of 67 Neutral Note: 1).Pre-scan all modes and recorded the worst case results in this report (IEEE 802.11b Low Channel). 2).

Band-edge measurements for radiated emissions 5.8.1 Standard Applicable In any 100 kHz bandwidth outside the frequency band in which the spread spectrum or digitally modulated intentional radiator is operating, the radio frequency power that is produced by the intentional radiator shall be at least 20 dB 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 the transmitter demonstrates compliance with the peak conducted power limits. If the transmitter complies with the conducted power limits based on the use of RMS averaging over a time interval, as permitted under paragraph (b)(3) of this section, the attenuation required under this paragraph shall be 30 dB instead of 20 dB. Attenuation below the general limits specified in §15.209(a) is not required. In addition, radiated emissions which fall in the restricted bands, as defined in §15.205(a), must also comply with the radiated emission limits specified in §15.209(a) (see §15.205(c)). 5.8.2 Test Setup Layout For Radiated For Conducted 5.8.3. Measuring Instruments and Setting Please refer to equipment list in this report. The following table is the setting of Spectrum Analyzer. Report No.: TZ201101788-E Page 63 of 67 5.8.4. Test Procedures Radiated Method: 1. The EUT was placed on a turn table which is 0.8m above ground plane. 2. Maximum procedure was performed by raising the receiving antenna from 1m to 4m and rotating the turn table from 0°C to 360°C to acquire the highest emissions from EUT. 3. And also, each emission was to be maximized by changing the polarization of receiving antenna both horizontal and vertical. 4. Repeat above procedures until all frequency measurements have been completed.. 5. The distance between test antenna and EUT was 3 meter: 6. Setting test receiver/spectrum as following table states: Test Frequency range Test Receiver/Spectrum Setting Detector 1GHz-40GHz Peak Value: RBW=1MHz/VBW=3MHz, Sweep time=Auto Average Value: RBW=1MHz/VBW=10Hz, Sweep time=Auto Peak Conducted Method: According to KDB 558074 D01 for Antenna-port conducted measurement. Antenna-port conducted measurements may also be used as an alternative to radiated measurements for demonstrating compliance in the restricted frequency bands. If conducted measurements are performed, then proper impedance matching must be ensured and an additional radiated test for cabinet/case spurious emissions is required. 1. Check the calibration of the measuring instrument using either an internal calibrator or a known signal from an external generator. 2. Remove the antenna from the EUT and then connect to a low loss RF cable from the antenna port to an EMI test receiver, then turn on the EUT and make it operate in transmitting mode. Then set it to Low Channel and High Channel within its operating range, and make sure the instrument is operated in its linear range. 3. Set both RBW and VBW…
