Antenna Beam Characterization of 5G Mobile Devices and Base Stations Using the R&S®NRPM Over-the-Air (OTA) Power Measurement Solution

The application note contains theoretical background on OTA power and pattern measurements. It gives step-by-step instructions for the verification of the power level and the radiation pattern of a device under test (DUT) in comparison to a golden device, and it presents an approach for verifying the accuracy of beam steering.

LTE-Advanced Pro Introduction eMBB Technology Components in 3GPP Release 13/14

Concrete and confined use cases such as mobile voice in 2G and mobile data in 4G dominated the definition of past cellular technologies. In contrast, 5G introduces a paradigm change towards a user/application centric technology framework that aims to support the following triangle of important use case families. The enhanced mobile broadband (eMBB) use case represents the well-known continuation of the ever-increasing requirement to support both higher peak data rates per user and more system capacity. Learn more about this hot topic in our Whitepaper.

LTE UE Receiver Performance Measurements

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.

Rohde & Schwarz Helps Developers Optimize Power Supplies in Wireless Devices

The new R&S RT-ZVC02/04 multichannel power probe can measure across large current and voltage ranges without having to switch ranges, making it possible to monitor the power consumption of chipsets, radio modules and wearables such as smartwatches. When used in combination with an R&S RTE or R&S RTO oscilloscope, the current drain can be clearly correlated with analog and digital control signals, enabling developers to optimize the battery life of such wearables and wireless devices early in the development cycle.
