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.

Rohde & Schwarz leverages technology from Analog Devices to develop a wireless battery management system production test solutionAnalog Devices, Inc. (ADI) and Rohde & Schwarz are helping the automotive industry to adopt wireless battery management system (wBMS) technology which brings technical, environmental, and cost advantages compared with wired battery management systems (BMS). A new automated test solution is tailored for verification and mass production tests of wireless device tests. This development builds on existing efforts for wBMS RF robustness testing.
On display is the over-the-air (OTA) measurement with high rate pulses (HRP) on a real UWB device inside shielding chamber R&S®TS7124. ulta wideband test, uwb ota testing, Ultra wideband testing Ultra-wideband communication, as standardized by IEEE 802.15.4 enables very low power communication and very accurate ranging in license-exempt spectrum.
Точно и достоверно измерить абсолютный уровень мощности по эфиру — задача не из простых, поскольку традиционная конфигурация базируется на нескольких различных компонентах. В датчиках мощности с измерением по эфиру R&S®NRPM-A90(D) многие погрешности устранены благодаря особенностям конструкции, а оставшиеся не превышают гарантированных значений.
