full_form: Near Field To Far-field
context: The NFTF method computes the metrics defined in Far Field by using the Near Field to Far Field transformation. The NFTF measurement setup of UE RF characteristics for FR2 is capable of centre and off centre of beam measurements and an example setup is shown in Figure B.2.5.1-1: Figure B.2.5.1-1: Example of NFTF measurement setup The key aspects of the Near Field test range are: - Radiated Near Field UE beam pattern is measured and based on the NFTF mathematical transform, the final metric such as EIRP is the same as the metric for the baseline setup - A positioning system such as the angle between the dual-polarized measurement/link antenna and the DUT has at least two axes of freedom and maintains a polarization reference - For setups intended for measurements of UE RF characteristics in non-standalone (NSA) mode with 1UL configuration, an LTE link antenna is used to provide the LTE link to the DUT. The LTE link antenna provides a stable LTE signal without precise path loss or
description: Near Field To Far-field (NFTF) is a method for transforming near field measurements into far field metrics, used in the context of UE RF characteristics testing for FR2. It enables the computation of metrics such as EIRP by applying mathematical transformations to the measured near field beam patterns.
explanation: The provided description details NFTF as a technological process involving mathematical transformations applied to near-field measurements for calculating far-field metrics in the context of wireless communication testing.
