name: OTA
full_form: Over-the-Air
context: The high level objective of this study item is to define a 3GPP methodology for measuring the radiated performance of multiple antenna reception and MIMO receivers in the UE. The test methodology should be relevant for HSPA and LTE technologies, with particular focus on handheld devices and devices embedded in laptop computers. The steps intended to achieve this involve the following: 1) Identify the performance metrics and clarify the requirements of operators for defining such a methodology. 2) Review of potential solutions also considering input from CTIA ERP and COST 2100. 3) Agree the final solution, and detail the agreed 3GPP solution in a technical report to be reported to RAN plenary. 4) Maintain ongoing communication with COST 2100 and CTIA ERP to ensure industry coordination on this topic. TSG RAN should contact TSG GERAN to get feedback on the applicability of such a test methodology for GERAN.
description: Over-the-Air (OTA) transmission refers to the wireless transfer of signals through the airwaves without physical cables. In 3GPP TS 37.843, OTA focuses on spatial requirements for beam steering systems in antenna arrays, defining coverage range and peak directions.
explanation: OTA is classified as a Wireless Communication Technology because it describes the fundamental method of signal transmission used in wireless communication systems. The context emphasizes its application in antenna array design and beam steering, which are core aspects of modern wireless technologies.
