LTE user equipment (UE) receiver performance has significant impact to cellular radio network coverage and capacity. It determines the maximum data throughput across the air interface between the LTE base station (eNB, evolved node B) and the mobile network subscriber UE, thus it determines the total capacity across the air interface. Therefore, it is one of the most important measurements to verify the actual receiver performance of individual devices, and a key metric to compare different devices, in particular.This paper shall give an introduction to receiver performance measurements and discusses the measurement metrics as well as the challenges of over the air (OTA) measurements.

现代移动电话能够同时支持蜂窝和非蜂窝无线通信标准。但这也意味着单个设备内的子系统在操作时相互靠近（设备内共存）。产生的相互泄漏有时候可能引起强干扰。本应用指南使用初步理论分析，并展示了如何测量设备内共存的问题。如需获取德文版本，请访问 。
