Rohde & Schwarz Extends Collaboration with Thales to Minimize Field Testing for IoT Modules

Rohde & Schwarz and Gemalto, a Thales company, are working on significantly reducing expensive and
time-consuming drive tests. IoT protocol stack features have been specified by 3GPP, but IoT devices have
to interact with different network configurations worldwide. This makes it important to ensure that these
features are working well in all sorts of configurations, configured by different network operators.
Thanks to the current cooperation, manufacturers of IoT solutions can use virtual drive tests during the
development phase of CAT M1 and NB IoT modules to find and fix problems at an earlier stage.

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.
