Position 1 is the perpendicular orientation of the probe coil; orientation 2 is the transverse orientations. The space between the measurement positions is not fixed. It is recommended that a scan of the WD be done for each probe coil orientation and that the maximum level recorded be used as the reading for that orientation of the probe coil. 1) The reference plane is the planar area that contains the highest point in the area of the phone that normally rests against the user's ear. It is parallel to the centerline of the receiver area of the ©Copyright. All rights reserved by CTTL. Page 13 of 70 No.I22Z61716-SEM03 phone and is defined by the points of the receiver-end of the WD handset, which, in normal handset use, rest against the ear. 2) The measurement plane is parallel to, and 10 mm in front of, the reference plane. 3) The reference axis is normal to the reference plane and passes through the center of the receiver speaker section (or the center of the hole array); or may be centered on a secondary inductive source. The actual location of the measurement point shall be noted in the test report as the measurement reference point. 4) The measurement points may be located where the axial and radial field intensity measurements are optimum with regard to the requirements. However, the measurement points should be near the acoustic output of the WD and shall be located in the same half of the phone as the WD receiver. In a WD handset with a centered receiver and a circularly symmetrical magnetic field, the measurement axis and the reference axis would coincide. 5) The relative spacing of each measurement orientation is not fixed. The axial and two radial orientations should be chosen to select the optimal position. 6) The measurement point for the axial position is located 10 mm from the reference plane on the measurement axis. The actual location of the measurement point shall be noted in test reports and designated as the measurement reference point.

Page 14 of 70 No.I22Z61716-SEM03 6 T-Coil TEST PROCEDUERES The following illustrate a typical test scan over a wireless communications device: 1) Geometry and signal check: system probe alignment, proper operation of the field probe, probe measurement system, other instrumentation, and the positioning system was confirmed. A surface calibration was performed before each setup change to ensure repeatable spacing and proper maintenance of the measurement plane using the test Arch. 2) Set the reference drive level of signal voice defined in C63.19 per 7.4.2.1. 3) The ambient and test system background noise (dB A/m) was measured as well as ABM2 over the full measurement. The maximum noise level must be at least 10dB below the limit. 4) The DUT was positioned in its intended test position, acoustic output point of the device perpendicular to the field probe. 5) The DUT operation f or maximum rated RF output power was conf igured and connected by using of coaxial cable connection to the base station simulator at the test channel and other normal operating parameters as intended for the test. The battery was ensured to be fully charged before each test. The center sub-grid was centered over the center of the acoustic output (also audio band magnetic output, if applicable). The DUT audio output was positioned tangent (as physically possible) to the measurement plane. 6) The DUT's RF emission field was eliminated from T-coil results by using a well RF-shielding of the probe, AM1D, and by using of coaxial cable connection to a Base Station Simulator. One test channel was pre-measurement to avoid this possibility. 7) Determined the optimal measurement locations for the DUT by following the three steps, coarse resolution scan, fine resolution scans, and point measurement, as described in C63.19 per 7.4.4.2. At each measurement locations, samples in the measurement window duration were evaluated to get ABM1 and the signal spectrum. The noise measurement was performed after the scan with the signal, the same happened, just with the voice signal switched off. The ABM2 was calculated from this second scan. 8) All results resulting from a measurement point in a T -Coil job were calculated from the signal samples during this window interval. ABM values were averaged over the sequence of there samples. 9) At an optimal point measurement, the SNR (ABM1/ABM2) was calculated for perpendicular and transverse orientation, and the frequency response was measured for perpendicular. 10) Corrected for the frequency response after the DUT measurement since the DASY5 system had known the spectrum of the input signal by using a reference job. 11) In SEMCAD postprocessing, the spectral points are in addition scaled with the high -pass (halfband) and the A-weighting, bandwidth compensated factor (BWC) and those results are final as shown in this report. ©Copyright.

Figure 7.1 and Figure 7.2 provide the boundaries for the specified frequency. These response curves are for true field strength measurements of the T-Coil signal. Thus the 6 dB/octave probe response has been corrected from the raw readings. Figure 7.1--Magnetic field frequency response for WDs with a field 15 dB (A/m) at 1 kHz Figure 7.2--Magnetic field frequency response for WDs with a fieldthat exceeds 15 dB(A/m) at 1 kHz ©Copyright. All rights reserved by CTTL. Page 16 of 70 No.I22Z61716-SEM03 7.3 Signal quality This part provides the signal quality requirement for the intended T-Coil signal from a WD. Only the RF immunity of the hearing aid is measured in T-Coil mode. It is assumed that a hearing aid can have noimmunity to an interference signal in the audio band, which is the intended reception band for this mode. So, the only criteria that can be measured is the RF immunity in T-Coil mode. This is measured using the same procedure as for the audio coupling mode and at the same levels. The worst signal quality of the three T-Coil signal measurements shall be used to determine the TCoil mode category per Table 1 Category Category T1 Category T2 Category T3 Category T4 Table 1:T-Coil signal quality categories Telephone parameters WD signal quality [(signal + noise) to noise ratio in decibels] 0 dB to 10 dB 10 dB to 20 dB 20 dB to 30 dB > 30 dB ©Copyright.

Per 3GPP TS 36.211, the total frame length for each TDD radio frame of length T f=307200.Ts=10 ms, where Ts is a number of time units equal to 1/(150002048) seconds. Additionally, each radio frame consists of 10 subframes, each of length 30720*Ts= 1ms, and subframes can be designated as uplink (U), downlink (D), or special subframe (S), depending on the Uplink -Downlink configuration as indicated in Table 4.2-2 of 3GPP TS 36.211.

Duo uses the OPUS audio codec and supports a bitrate range of 6kbps to 75kbps. All air interfaces capable of a data connection were evaluated with Google Duo. When HAC testing we are using the Google Duo version is 26.0.179825522.alpha.DEV and the bitrate configuration can find at settings Voice call parameters settings Audio codec bitrate(6-75kbps). Test Procedure and Equipment Setup The test procedure for OTT testing is identical to the section above, except for how the signal is sent to the DUT, as outlined in the diagram below. The AMMI is connected to the support device's Mic via Audio Data Line. The support device is connected to the Internet via Wi-Fi and the DUT is connected to the mobile base station via the technology under test. Using the DUT's OTT application, a VoIP call is established with the support device. The test signal is sent fromthe DASY PC to the AMMI, from the AMMI to the support device, and finally to the DUT. To exercise the license antenna, the DUT was simultaneously connected to an external AP and to a mobile base station. Device1 ©Copyright. All rights reserved by CTTL.

Determine Input Audio level is based on the Added additional dBFS level readout by Google Duo customize application and three steps need to do. 1. Input a gain value to readout the -23dBFS level as reference. (0dBFS = 3.14 dBm0) 2. Adjust gain level to readout the dBFS level until it changes to -24dBFS. 3. Based on the step 1 and 2, and then calculate the gain value(dB) by interpolation to get the - 20dBm0 corresponding gain value. Codec Bit-rate Investigation An investigation between the various bit-rate configurations (Low/Mid/High bit rates for Narrowband, Wideband, and EVS) are documented (ABM, SNNR, frequency response) to determine the worst case bit-rate for each voice service type. The tables below compare the varying bit -rate conf igurations Air Interface Investigation Using the worst-case bit-rate and Radio Configuration found in §11.2/11.3/11.4, a limited set of bands/channel/ bandwidths were then tested to confirm that there is no effect to the T -rating when changing the band/channel/bandwidth, it is necessary to report only a set band/channel/bandwidth for each orientation for a voice service/air interface. ©Copyright.
