RF EXPOSURE EVALUATION REPORT Report No. : FA890514B 4. RF Exposure Limits 4.1 Uncontrolled Environment Uncontrolled Environments are defined as locations where there is the exposure of individuals who have no knowledge or control of their exposure. The general population/uncontrolled exposure limits are applicable to situations in which the general public may be exposed or in which persons who are exposed as a consequence of their employment may not be made fully aware of the potential for exposure or cannot exercise control over their exposure. Members of the general public would come under this category when exposure is not employment-related; for example, in the case of a wireless transmitter that exposes persons in its vicinity. 4.2 Controlled Environment Controlled Environments are defined as locations where there is exposure that may be incurred by persons who are aware of the potential for exposure, (i.e. as a result of employment or occupation). In general, occupational/controlled exposure limits are applicable to situations in which persons are exposed as a consequence of their employment, who have been made fully aware of the potential for exposure and can exercise control over their exposure. The exposure category is also applicable when the exposure is of a transient nature due to incidental passage through a location where the exposure levels may be higher than the general population/uncontrolled limits, but the exposed person is fully aware of the potential for exposure and can exercise control over his or her exposure by leaving the area or by some other appropriate means. The criteria listed in Table 1 shall be used to evaluate the environmental impact of human exposure above 6GHz to radio frequency (RF) radiation as specified in §1.1310. 2 General Population Basic restriction for power density for frequencies between 1.5GHz and 100 GHz is 1.0 mW/cm = 10 2 W/m Table 1 TEL : 886-3-327-3456 Page 6 of 27 FAX : 886-3-328-4978 Issued Date : Mar. 02, 2019 Form version: 180516

The device under test is mounted on a support that can hold it at the desired test orientation and test distance, and the device on its mount is then slid under the flat phantom filled with normal temperature water, while the control software is monitored to determine if/when the sensor is triggered. The basic setup is illustrated in below figure. 3. All tests are performed with the 5G Mod attached to the host phone device. The procedure for testing is as follows: 1. Adjust the height of the 5G Mod on the platform 2. Place the platform w/ the 5G Mod away from the Flat Phantom 3. Move the platform w/ 5G Mod under the center of Flat Phantom 4. Check the sensor state, mmwave array module ON/OFF state 5. Repeated above procedure in 1 cm steps until the sensor release. 6. This basic test procedure was applied at multiple spacings, in 1 cm increments, starting from a large spacing and reducing to a small spacing, and starting from a small spacing, and increasing to a large spacing. In this way the minimum detection distance was established for each module, and any hysteresis effects were taken into account. Steps of 1 cm were employed, rather than smaller steps of 3 or 1 mm as are commonly used to test capacitive proximity sensors, because of the much larger operational range of the thermal sensor. Note that using a larger step size of 1 cm produces a more conservative result, i.e. the smallest detection distance so found is equal to or less than that which would be found if using smaller step sizes like 1 mm. 7. Additionally, the test procedure was followed at a close distance of 5 mm from the device, to establish the extents of the angular cone of detection of each sensor, which was used to establish the measurement inclusion and exclusion zones in those measurement planes. Testing at this close spacing (corresponding to the actual measurement planes) is a more conservative means of establishing these characteristics of the sensor. Result: Right/Left/Back array module will turn off at detection distance of 12cm, Front array module turns off at detection distance of 7cm. Test separation of 7cm was chosen conservatively for ALL array module TEL : 886-3-327-3456 Page 16 of 27 FAX : 886-3-328-4978 Issued Date : Mar. 02, 2019 Form version: 180516

The 5G NR n261 signal under testing was configured by test Qualcomm software, and the test tool can be used and set the relevant 5G radio parameters (e.g. TX carrier, polarization, band, channel, bandwidth and output power etc.) 2. The device was configured to transmit maximum power and at 100% duty cycle, for each RB configuration/modulation/bandwidth/channel to be tested 3. Since the device Supports dual-polarization MIMO (2 × 2 uplink (UL) and 2 × 2 downlink (DL), therefore the device under test was configured beam pair testing at a time. 4. According to manufacturer simulation test results for different antenna modules and exposure planes, limited worst cases were selected for power density measurement. 5. This device support 5GNR n261.The frequency range is 27.5GHz to 28.35GHz. The maximum supporting bandwidth is 400MHz for UL. The modulation type is QPSK, 16QAM, and 64QAM for CP-OFDM for both of DL and UL and the Subcarrier spacing is120 kHz. 6. According to TCBC Workshop in October 2018, 4 cm2 averaging area may now be considered. 7. The power density test separation distance and test conditions were confirmed by FCC in the lab KDB inquiry. The device implements the sensor detection, so that for some device orientations the PD test at default test separation was skipped and PD was tested at larger distance which represents the sensor detection range 8. Above 6 GHz, Maximum Permissible Exposure (MPE) limits apply to portable exposure conditions according to 47 CFR §2.1093.

RF EXPOSURE EVALUATION REPORT Report No. : FA890514B 12.1 Computation of the Electric Field Polarization Ellipse For the numerical description of an arbitrarily oriented ellipse in three-dimensional space, five parameters are needed: the semi-major axis (a), the semi-minor axis (b), two angles describing the orientation of the normal vector of the ellipse (∅, θ), and one angle describing the tilt of the semi-major axis (ψ). For the two extreme cases, i.e., circular and linear polarizations, three parameters only (a, ∅ and θ) are sufficient for the description of the incident field. Illustration of the angles used for the numerical description of the sensor and the orientation of an ellipse in 3-D space. For the reconstruction of the ellipse parameters from measured data, the problem can be reformulated as a nonlinear search problem. The semi-major and semi-minor axes of an elliptical field can be expressed as functions of the three angles (∅, θ and ψ). The parameters can be uniquely determined towards minimizing the error based on least-squares for the given set of angles and the measured data. In this way, the number of free parameters is reduced from five to three, which means that at least three sensor readings are necessary to gain sufficient information for the reconstruction of the ellipse parameters. However, to suppress the noise and increase the reconstruction accuracy, it is desirable that the system of equations be over determined. The solution to use a probe consisting of two sensors angled by r1 and r2 toward the probe axis and to perform measurements at three angular positions of the probe, i.e., at β1, β2 and β3, results in over-determinations by a factor of two. If there is a need for more information or increased accuracy, more rotation angles can be added. The reconstruction of the ellipse parameters can be separated into linear and non-linear parts that are best solved by the Givens algorithm combined with a downhill simplex algorithm. To minimize the mutual coupling, sensor angles are set with a shift of 90 degree (r2 = r1 + 90 degree), and to simplify, the first rotation angle of the probe (β1) can be set to 0 degree 12.2 Total Field and Power Flux Density Reconstruction Computation of the power density in general requires knowledge of the electric and magnetic field amplitudes and phases in the plane of incidence. Reconstruction of these quantities from pseudo-vector E-field measurements is feasible, as they are constrained by Maxwell's equations. SPEAG have developed a reconstruction approach based on the Gerchberg-Saxton algorithm, which benefits from the availability of the E-field polarization ellipse information obtained with the EUmmWV2 probe. The average of the reconstructed power density is evaluated over a circular area in each measurement plane. Two average power density values can be computed, the average total power density and the average incident power density, and the average total power density is used to determine compliance. The software post-processing reports to values, “S avg tot” and “S avg inc”. “S avg tot” represents average total power density (all three xyz components included), and “S avg inc” represents average normal power density. The average total power density “S avg tot” is reported to determine the device compliance. TEL : 886-3-327-3456 Page 21 of 27 FAX : 886-3-328-4978 Issued Date : Mar. 02, 2019 Form version: 180516

The test position/separation and the area to scan for each test is selected and identified in the simulation report, details in illustrated in the simulation report exhibit and the operational description. 2. For each array module, power density for different combinations of RB/modulation/bandwidth and also low/middle/high channel was executed at the worst position. 3. The test positions are defined per the front view of phone+Mod. Note that for the measurements, "right" and "left" are referenced with respect to viewing from the front, display side of the phone+Mod, but it contrasts with the reference used in the simulation reports which the reference is from the back view of the Mod" 4. 2 mm “Test separation” means 0.5 mm between probe-housing tip and DUT, with 1.5 mm from probe-housing tip to center of sensing elements. 5. The page 5 and 6 in the appendix is for the measurement which partially overlaps device footprint due to sensor cone exclusion, the 4 cm2^ averaging causes a further reduction of the displayed PD area.
