A.4 Conducted Spurious Emission A.4.1 Reference FCC CFR 47 Part 2, Clause 2.1051 FCC CFR 47 Part 90, Clause 90.543 A.4.2 Method of measurement In accordance with FCC rules, the power of any emission outside of the authorized operating frequency ranges must be attenuated below the transmitting power (P) by a factor of at least 43 + 10 log(P) dB or 76 + 10 log (P) dB. The spurious emissions from the antenna terminal were measured. The transmitter output power was attenuated using an attenuator and the frequency spectrum investigated from 3KHz to 8GHz. The resolution bandwidth of 100KHz was employed for frequency band 3KHz to 1GHz, resolution bandwidth of 6.25KHz was employed for frequency band 769MHz to 805MHz and resolution bandwidth of 1MHz was employed for frequency band 1GHz to 8GHz. The spectrum analyzer detector was set to RMS. For MIMO mode configurations, the limit was adjusted with a correction of -3.01dB [10Log2] by using the Measure and Add 10Log(N) dB technique according to FCC KDB 662911 D01 Multiple Transmitter Output accounting for simultaneous transmission from antenna ports RF A and B. A.4.3 Measurement limit (e) For operations in the 758–768 MHz and the 788–798 MHz bands, the power of any emission outside the licensee’s frequency band(s) of operation shall be attenuated below the transmitter power (P) within the licensed band(s) of operation, measured in watts, in accordance with the following: (1) On all frequencies between 769–775MHz and 799–805 MHz, by a factor not less than 76 + 10 log (P) dB in a 6.25 kHz band segment, for base and fixed stations. (3) On any frequency between 775–788MHz, above 805 MHz, and below 758MHz, by at least 43 + 10 log (P) dB. (4) Compliance with the provisions of paragraphs (e)(1) and (2) of this section is based on the use of measurement instrumentation such that the reading taken with any resolution bandwidth setting should be adjusted to indicate spectral energy in a 6.25 kHz segment. (5) Compliance with the provisions of paragraph (e)(3) of this section is based on the use of measurement instrumentation employing a resolution bandwidth of 100 kHz or greater. However, in the 100 kHz bands immediately outside and adjacent to the frequency block, a resolution bandwidth of 30 kHz may be employed. ©Copyright. All rights reserved by CTTL. Page 39 of 64

A.5 Radiated Spurious Emission A.5.1 Reference FCC CFR 47 Part 2, Clause 2.1053 FCC CFR 47 Part 90, Clause 90.543 A.5.2 Method of measurement The measurements procedures in TIA-603-E: 2016 are used. This measurement is carried out in semi-anechoic chamber. A preliminary profile of the Spurious Radiated Emissions was obtained by operating the EUT on a remotely controlled turntable within the chamber. Measurements of emissions from the EUT were obtained with the measurement antenna in both horizontal and vertical polarizations. The measurements in the frequency range 30 to 1000MHz was performed with a RBW of 100kHz except in the frequency bands 769 to 775MHz and 799 to 805 MHz where a RBW of 10kHzwas used. The measurements in the frequency range 1 to 8GHz was performed with a RBW of 1MHz except in the frequency band 1559 to 1610MHz where a RBW of 10kHz was used. Emissions identified within the range 30MHz to 8GHz were then formally measured using a peak detector as the worst case. The limits for outside a licensee’s frequency band(s) of operation the power of the spurious emissions have been calculated, as shown below using the following formula: Field Strength of Carrier - (43 + 10Log (P)) dB Where: Field Strength is measured in dBμV/m P is measured Transmitter Power in Watts The EUT was measured with the antenna height varied between 1 and 4 m with the turntable rotated between 0 and 360 degrees. The emission of any outside a licensee’s frequencies within 20dB of the limit were measured with the substitution method used according to the standard. The measurements were performed at a 3m distance unless otherwise stated. A.5.3 Measurement limit The field strength of the carrier has been calculated assuming that the power is to be fed to a half-wave tuned dipoles as per 2.1053 (a). E(v/m)=(30 x Gi x Po )0.5 / d Where Gi is the antenna gain of ideal half-wave dipoles, Po is the power out of the transceiver in W, d is the measurement distance in meter. Therefore at 3m measurement distance the field strength using the lowest transceiver output power would be: E(v/m)=(30 x 1.64 x 16.56)0.5 / 3 = 9.51V/m = 139.57 dBμV/m As per 90.543 (e) For operations in the 758-768 MHz and the 788-798 MHz bands, the power of any emission outside the licensee's frequency band(s) of operation shall be attenuated below the transmitter power (P) within the licensed band(s) of operation, measured in watts, in accordance with the following: ©Copyright.

(1) On all frequencies between 769-775 MHz and 799-805 MHz, by a factor not less than 76 + 10 log (P) dB in a 6.25 kHz band segment, for base and fixed stations. this gives: 76 + 10log(16.56) = 88.19 dB Therefore the limit at 3m measurement distance is: 139.57 – 88.19 = 51.4 dBμV/m (2) On all frequencies between 769-775 MHz and 799-805 MHz, by a factor not less than 65 + 10 log (P) dB in a 6.25 kHz band segment, for mobile and portable stations. (3) On any frequency between 775-788 MHz, above 805 MHz, and below 758 MHz, by at least 43 + 10 log (P) dB. this gives: 43 + 10log(16.56) = 55.19 dB Therefore the limit at 3m measurement distance is: 139.57 – 55.19 = 84.4 dBμV/m (4) Compliance with the provisions of paragraphs (e)(1) and (2) of this section is based on the use of measurement instrumentation such that the reading taken with any resolution bandwidth setting should be adjusted to indicate spectral energy in a 6.25 kHz segment. (5) Compliance with the provisions of paragraph (e)(3) of this section is based on the use of measurement instrumentation employing a resolution bandwidth of 100 kHz or greater. However, in the 100 kHz bands immediately outside and adjacent to the frequency block, a resolution bandwidth of 30 kHz may be employed. (f) For operations in the 758-775 MHz and 788-805 MHz bands, all emissions including harmonics in the band 1559-1610 MHz shall be limited to −70 dBW/MHz equivalent isotropically radiated power (EIRP) for wideband signals, and −80 dBW EIRP for discrete emissions of less than 700 Hz bandwidth. For the purpose of equipment authorization, a transmitter shall be tested with an antenna that is representative of the type that will be used with the equipment in normal operation. These limits have been used to determine Pass or Fail for the harmonics measured and detailed in the following results. ©Copyright. All rights reserved by CTTL. Page 53 of 64
