The use of a permanently attached antenna or of an antenna that uses a unique coupling to the intentional radiator shall be considered sufficient to comply with the provisions of this Section. The manufacturer may design the unit so that a broken antenna can be replaced by the user, but the use of a standard antenna jack or electrical connector is prohibited. And according to §15.247(b)(4), the conducted output power limit specified in paragraph (b) of this section is based on the use of antennas with directional gains that do not exceed 6 dBi. Except as shown in paragraph (c) of this section, if transmitting antennas of directional gain greater than 6 dBi are used, the conducted output power from the intentional radiator shall be reduced below the stated values in paragraphs (b)(1), (b)(2), and (b)(3) of this section, as appropriate, by the amount in dB that the directional gain of the antenna exceeds 6 dBi. 5.1.2 Result: PASS The transmitter has the integral chip antenna. The directional gain of the antenna is -1.89 dBi.

The minimum 6dB bandwidth shall be at least 500 kHz. 5.2.2 Test Procedure 1. Connect the antenna port of the EUT to RF input on the spectrum analyzer via a low loss cable. 2. Set the spectrum analyzer as follows: RBW = 100 kHz, VBW  RBW Span >> RBW Sweep = auto Detector function = peak Trace = max hold 3. Mark the peak frequency and -6dB (upper and lower) frequency. 4. Set the RBW to as close to 1% of the selected span as is possible without being below 1%. 5. Set the DETECTOR to sample where practical. [REMARK: the function of the PEAK HOLD was used] 6. Measure the 99% occupied bandwidth. 7. Repeat until all the rest channels are investigated. 5.2.3 Test Results: PASS Table 1: Measured values of the 6dB Bandwidth Occupied Bandwidth Modulation Operating frequency Transfer Rate (99%) 6dB Bandwidth Limit 2412 MHz 11 Mbps 14.31 MHz 9.32 MHz ≥ 500 kHz 802.11b 2437 MHz 11 Mbps 14.25 MHz 9.31 MHz ≥ 500 kHz 2462 MHz 11 Mbps 14.25 MHz 9.31 MHz ≥ 500 kHz 2412 MHz 54 Mbps 16.41 MHz 16.26 MHz ≥ 500 kHz 802.11g 2437 MHz 54 Mbps 16.41 MHz 16.26 MHz ≥ 500 kHz 2462 MHz 54 Mbps 16.35 MHz 16.26 MHz ≥ 500 kHz

Page 12 of 31 5.3 MAXIMUM PEAK OUTPUT POWER 5.3.1 Regulation According to §15.247(b)(3), for systems using digital modulation in the 902-928 MHz, 2400-2483.5 MHz, and 5725-5850 MHz bands: 1 Watt. As an alternative to a peak power measurement, compliance with the one Watt limit can be based on a measurement of the maximum conducted output power. Maximum Conducted Output Power is defined as the total transmit power delivered to all antennas and antenna elements averaged across all symbols in the signaling alphabet when the transmitter is operating at its maximum power control level. Power must be summed across all antennas and antenna elements. The average must not include any time intervals during which the transmitter is off or is transmitting at a reduced power level. If multiple modes of operation are possible (e.g., alternative modulation methods), the maximum conducted output power is the highest total transmit power occurring in any mode. According to §15.247(b)(4), the conducted output power limit specified in paragraph (b) of this section is based on the use of antennas with directional gains that do not exceed 6 dBi. Except as shown in paragraph (c) of this section, if transmitting antennas of directional gain greater than 6 dBi are used, the conducted output power from the intentional radiator shall be reduced below the stated values in paragraphs (b)(1), (b)(2), and (b)(3) of this section, as appropriate, by the amount in dB that the directional gain of the antenna exceeds 6 dBi. 5.3.2 Test Procedure Conducted output power measurements were directly made by using Peak-Average power meter with peak power sensor. 1. Check the calibration of the measuring instrument using either an internal calibrator or a known signal from an external generator. 2. Connect the antenna port of the EUT to RF input on peak power meter via a low loss cable and attenuator. 3. Measure the peak output power. 5.3.3 Test Results: PASS Table 2: Measured values of the Maximum Peak Conducted Output Power Operating AVERAGE POWER PEAK POWER Modulation Transfer Rate Limit Frequency [dBm] [W] [dBm] [W] 2412 MHz 7.47 0.0056 9.28 0.0085 1W 802.11b 2437 MHz 11 Mbps 8.33 0.0068 10.16 0.0104 1W 2462 MHz 9.07 0.0081 10.90 0.0123 1W 2412 MHz 4.90 0.0031 11.26 0.0134 1W 802.11g 2437 MHz 54 Mbps 5.75 0.0038 12.16 0.0164 1W 2462 MHz 6.43 0.0044 12.96 0.0198 1W NOTE: The average RF power was measured during ON time intervals excluding OFF time intervals by the using trigger function of the power meter

Page 13 of 31 5.4 SPURIOUS EMISSIONS, BAND EDGE, AND RESTRICTED BANDS 5.4.1 Regulation According to §15.247(d), 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 Section 15.209(a) is not required. In addition, radiated emissions which fall in the restricted bands, as defined in Section 15.205(a), must also comply with the radiated emission limits specified in Section 15.209(a) (see Section 15.205(c)). According to §15.209(a), for an intentional device, the general requirement of field strength of radiated emissions from intentional radiators at a distance of 3 meters shall not exceed the following values: Frequency (MHz) Field strength (µV/m @ 3m) Field strength (dBµV/m @ 3m) 30–88 100 40.0 88–216 150 43.5 216–960 200 46.0 Above 960 500 54.0 According to §15.109(a), for an unintentional device, except for Class A digital devices, the field strength of radiated emissions from unintentional radiators at a distance of 3 meters shall not exceed the above table. ** The emission limits shown in the above table are based on measurement instrumentation employing a CISPR quasi-peak detector and above 1000 MHz are based on the average value of measured emissions. 5.4.2 Test Procedure 1) Band-edge Compliance of RF Conducted Emissions 1. Set the spectrum analyzer as follows: Span = wide enough to capture the peak level of the emission operating on the channel closest to the bandedge, as well as any modulation products which fall outside of the authorized band of operation RBW  1% of the span VBW  RBW Sweep = auto Detector function = peak Trace = max hold 2. Allow the trace to stabilize. Set the marker on the emission at the band-edge, or on the highest modulation product outside of the band, if this level is greater than that at the band-edge. Enable the marker-delta function, and then use the marker-to-peak function to move the marker to the peak of the in-band emission. 3. Now, using the same instrument settings, enable the hopping function of the EUT. Allow the trace to stabilize. Follow the same procedure listed above to determine if any spurious emissions caused by the hopping function also comply with the specified limit.

SKTRFC-110125-003 FCC ID: Y7A-SIPWFHS SK TECH CO., LTD. Page 14 of 31 2) Spurious RF Conducted Emissions: 1. Set the spectrum analyzer as follows: Span = wide enough to capture the peak level of the in-band emission and all spurious emissions (e.g., harmonics) from the lowest frequency generated in the EUT up through the 10th harmonic. Typically, several plots are required to cover this entire span. RBW = 100 kHz VBW  RBW Sweep = auto Detector function = peak Trace = max hold 2. Allow the trace to stabilize. Set the marker on the peak of any spurious emission recorded. 3) Spurious Radiated Emissions: 1. The preliminary radiated measurements were performed to determine the frequency producing the maximum emissions in an anechoic chamber at a distance of 3 meters for above 30 MHz, and at 1 meter distance for below 30 MHz. 2. The EUT was placed on the top of the 0.8-meter height, 1 × 1.5 meter non-metallic table. To find the maximum emission levels, the height of a measuring antenna was changed and the turntable was rotated 360˚. 3. The antenna polarization was also changed from vertical to horizontal. The spectrum was scanned from 9 kHz to 30 MHz using the loop antenna, from 30 to 1000 MHz using the Trilog broadband antenna, and from 1 GHz to tenth harmonic of the highest fundamental frequency using the horn antenna. 4. To obtain the final measurement data, the EUT was arranged on a turntable situated on a 4 × 4 meter at the Open Area Test Site. The EUT was tested at a distance 3 meters. 5. Each frequency found during preliminary measurements was re-examined and investigated. The test- receiver system was set up to average, peak, and quasi-peak detector function with specified bandwidth. 6. The EUT is situated in three orthogonal planes (if appropriate) 7. The presence of ambient signals was verified by turning the EUT off. In case an ambient signal was detected, the measurement bandwidth was reduced temporarily and verification was made that an additional adjacent peak did not exist. This ensures that the ambient signal does not hide any emissions from the EUT. 8. If the emission on which a radiated measurement must be made is located at the edge of the authorized band of operation, then the alternative “marker-delta” method may be employed. 4) Marker-Delta Method at the edge of the authorized band of operation: 1. Perform an in-band field strength measurement of the fundamental emission using the RBW and detector function as the above Spurious Radiated Emissions test procedure. 2. Choose a spectrum analyzer span that encompasses both the peak of the fundamental emission and the band-edge emission under investigation. Set the analyzer RBW to 1% of the total span (but never less than 30 kHz) with a video bandwidth equal to or greater than the RBW. Record the peak levels of the fundamental emission and the relevant band-edge emission (i.e., run several sweeps in peak hold mode). Observe the stored trace and measure the amplitude delta between the peak of the fundamental and the peak of the band-edge emission. This is not a field strength measurement; it is only a relative measurement to determine the amount by which the emission drops at the band-edge relative to the highest fundamental emission level. 3. Subtract the delta measured in step (2) from the field strengths measured in step (1). The resultant field strengths (CISPR QP, average, or peak, as appropriate) are then used to determine band-edge compliance as required by Section 15.205. 4. The above "delta" measurement technique may be used for measuring emissions that are up to two "standard" bandwidths away from the band-edge, where a "standard" bandwidth is the bandwidth specified by C63.4 for the frequency being measured. For example, for band-edge measurements in the restricted band that begins at 2483.5 MHz, C63.4 specifies a measurement bandwidth of at least 1 MHz. Therefore you may use the "delta" technique for measuring emissions up to 2 MHz removed from the band-edge. Radiated emissions that are removed by more than two “standard” bandwidths must be measured as the above Spurious Radiated Emissions test procedure.

SKTRFC-110125-003 FCC ID: Y7A-SIPWFHS SK TECH CO., LTD. Page 15 of 31 5.4.3 Test Results: PASS Band-edge compliance of RF conducted/radiated emissions was shown in the Figure 3 and 4. Spurious RF conducted emissions were shown in the Figure 5. Emission plot for the preliminary radiated measurements were shown in the Figure 6. NOTE 1: for conducted measurement, we took the insertion loss of the cable loss into consideration within the measuring instrument. And for radiated measurement, the results were calibrated to the field strength within the measuring instrument; Table 3 contains the correction factors at the operating frequencies such as antenna factor, cable loss, etc. NOTE 2: The preliminary radiated measurements were performed in the anechoic chamber in order to find the frequency, which falls in the restricted bands as defined in Section 15.205, and the results for the final measurements were indicated in the Table 3.

Page 29 of 31 5.5 PEAK POWER SPECTRAL DENSITY 5.5.1 Regulation According to §15.247(e), for digitally modulated systems, the power spectral density conducted from the intentional radiator to the antenna shall not be greater than 8 dBm in any 3 kHz band during any time interval of continuous transmission. This power spectral density shall be determined in accordance with the provisions of paragraph (b) of this section. The same method of determining the conducted output power shall be used to determine the power spectral density. 5.5.2 Test Procedure 1. Check the calibration of the measuring instrument using either an internal calibrator or a known signal from an external generator. 2. Connect the antenna port of the EUT to RF input on the spectrum analyzer via a low loss cable and attenuator. 3. Turn on the EUT and locate and zoom in on emission peak(s) within the passband. 4. Set the spectrum analyzer as follows: RBW = 3 kHz, VBW  RBW Span = 1.5 MHz Sweep = 500 seconds Detector function = peak Trace = max hold 5. Measure the highest amplitude appearing on spectral display and record the level to calculate results. 5.5.3 Test Results: PASS Table 4: Measured values of the Peak Power Spectral Density (Conducted) Modulation Operating frequency Transfer Rate Reading (PPSD) Limit 2412 MHz 11 Mbps -16.95 dBm 8.0 dBm 802.11b 2437 MHz 11 Mbps -16.13 dBm 8.0 dBm 2462 MHz 11 Mbps -15.30 dBm 8.0 dBm 2412 MHz 54 Mbps -21.32 dBm 8.0 dBm 802.11g 2437 MHz 54 Mbps -20.34 dBm 8.0 dBm 2462 MHz 54 Mbps -19.35 dBm 8.0 dBm NOTE: We took the insertion loss of the cable loss into consideration within the measuring instrument.
