EUT information:  QTM052_1, 2, 3 : 5G : n260/n261 ( 29/39 GHz)  There are three QTM’s 5G array antenna modules, and each 5G array antenna module consists of two sub-arrays. These three 5G arrays antenna modules do not operate simultaneously of each other. The purpose of the three spatially separated 5G arrays is for spatial diversity. As for beam-steering/beam-forming mechanism, the wide beam-width on the best array, sweeps begin to improve link, and beam-width then reduces on best beam location.

2. Test Plan Test Item FCC Part Section(s) Measurement Procedure Test Condition ANSI C63.26:2015 -Far-field mmWave Procedure Occupied Bandwidth 2.1094 (See following radiated measurement process) RF Output power/ 2.1046 / 30.202 ANSI C63.26:2015 -Far-field mmWave Procedure EIRP Radiated (See Figure-1) Spurious Emission 2.1051 / 30.203 ANSI C63.26:2015-Far-field mmWave Procedure Frequency Stability 2.1055 ANSI C63.26:2015-Far-field mmWave Procedure Radiated Measurement process (Far-field mmWave Procedure) 1. The radiated measurement will perform at an indoor 3 meter semic-anechoic chamber for final measurement. 2. Absorbers are arranged on the floor between the turn table and the antenna master for measurement above 1GHz. 3. Propose to adopt procedure from ANSI C63.26:2015 and KDB 842590 D01 4. The EUT is placed on turntable and receiver measurement antenna is located 3m (or less than 3m) from the EUT which is in the far field of the EUT per formula (2*D^2)/wavelength.

Table 2 – Measurement Distance Measurement Frequency range Far Field calculation distance Measurement Distance (Far field) Below 18GHz 0.05m 3m 18GHz to 40GHz 0.12m 1m 40GHz to 200GHz 0.12m to 0.59m 0.6m Note: EUT Antenna Dimension is 21mm length, 2.2mm think and 6.7mm high. 5. The EUT is manipulated through all orthogonal planes representative of its typical use to achieve the highest reading on spectrum. (see Figure-1 Test configuration) 6. Radiated power levels are investigated with the receiver antenna horizontally and vertically polarized. 7. The maximized power level is rescored using the spectrum analyzer channel power function with the integration band set to emission’s occupied bandwidth. The EIRP is calculated from the raw power level measured with the spectrum. 8. For band edge : The requirements in 30.203 are expressed in terms of conductive power, and then conducted power will be calculated by EIRP-Array Gain. 9. For out-of-band emission ( NOT include band edge ), the EIRP will be measured to demonstrate compliance with the requirement in section 30.203. Firgure-1: Test Configuration
