Rohde & Schwarz introduces signalling tests for 5G NR in FR1 and FR2 mode

Thu, Mar 12, 2020

Signalling tests for FR1 and FR2 in non-standalone mode can now be performed with the R&S CMX500. To test 5G NR products which use a much higher bandwidth, and active antennae, over-the-air (OTA) measurements are necessary. Rohde & Schwarz has created a portfolio for 5G NR device testing, based on the CMX500 radio communication tester enabling non-standalone (NSA) and standalone (SA) signalling tests in both FR1 and FR2 frequency ranges.

To allow developers to test their mobile devices in 5G NR NSA and SA mode in line with 3GPP specifications, the test must accurately simulate both LTE and 5G NR networks. The CMX500 radio communication tester adds 5G capability to the company’s LTE test systems (CMW500 or CMWflexx), to allow testing from 2G to 5G on one platform. The extension box R&S CMX500 handles various FR1 and FR2, signalling and non-signalling as well as SA and NSA test scenarios, from R&D to certification testing, confirms Rohde & Schwarz.

A key functionality of the R&S CMX500 is signalling tests in FR2 with support for signalling tests in FR1. The tests performed in NSA mode feature both LTE and 5G connections. They verify LTE/5G signalling protocol behaviour, OTA RF/TX measurements, end-to-end data testing with LTE and 5G bearers as well as mmWave OTA signalling and RF measurements.

Signalling test in the new mmWave-based 5G frequency of FR2 requires an OTA test set up or environment. The test set up features the R&S ATS800R CATR rack- based antenna test system with OTA functionalities. Designed for FR2 R&D measurements, it optimises the available lab space by combining a, compact shielding chamber with T&M equipment in the same set up, to minimise footprint. The integrated reflector surface precision provides a sufficiently large quiet zone with high accuracy, says Rohde & Schwarz.

To control the 5G radio communication testers, the test set up includes the newly developed R&S CMsquares unified test software. This integrates the mobile network simulation with test configuration, parameterisation, real time measurements and test result management in a single environment for all relevant use cases from RF parametric testing over protocol analysis to data end-to-end throughput tests.

It provides easiest user guidance via dashboards and customisable workspaces which allow quick access to the various types of 5G measurements. It also has a built-in sequencer to run pre-configured 5G NR test scripts or to create 5G NR test scripts from scratch using a simple drag-and-drop workflow.

Simpleware ScanIP software enhances its machine learning operation

Thu, Mar 12, 2020

Synopsys introduces a machine learning (ML) -based auto segmentation module for 3D image processing in the Simpleware ScanIP software. The ML-based option speeds up operation by up to a factor of 20 to 50, says the company and precisely automates segmentation for medical device design and pre-surgical planning.

The new ScanIP software module, Simpleware AS Ortho, uses automated algorithms to shorten segmentation time and produce accurate results significantly faster for medical image data, says the company.

The ML-based auto segmentation module builds on Synopsys’ ScanIP software, a comprehensive solution for 3D image processing and segmenting images generated by computed tomography (CT) or magnetic resonance imaging (MRI) scanners.

The Simpleware AS Ortho module is specifically designed for segmentation needs in patients’ hips and knees. When applying this automated option with Synopsys’ ScanIP software to run analysis, users will easily see a 20 to 50 times faster rate of segmentation for clinical images, Synopsys reports.

The technology is scalable and helps to achieve more consistency and increased reliability in biomechanical compatibility. It can also dramatically streamline the workflow process in both pre-surgical planning and medical device design.

“Image segmentation of MRI and CT scans presents a significant challenge for our surgical and engineering multidisciplinary teams. We’re excited to collaborate with the Simpleware product group at Synopsys for solutions to this challenge,” said Johann Henckel, MD orthopedic surgeon at the Royal National Orthopaedic Hospital, in the UK. “What is currently a laborious process that occupies significant engineering resources and time can now be completed quickly, accurately and with less variability, promising a scalable solution for generating high-fidelity patient specific models, surgical tools and bespoke implants,” he said.

“The demand for image-based modeling of human anatomy tools with ML-enabled intelligence is rapidly growing, especially in markets that include patient specific workflows for medical devices, surgical guides and planning, and in silico clinical trials,” said Terry Ma, vice president of engineering at Synopsys.

Synopsys’ Simpleware AS Ortho (Auto Segmenter for Orthopedics) launches in March 2020 as a Simpleware ScanIP software add-on module for hips and knees. Synopsys plans further modules to provide automated segmentation options for other anatomical regions. For users wanting any customisation or workflows applied to different anatomies, Synopsys’ Simpleware Custom Modeler option is also available as a tailored and automated software option.
