Demystifying 5G - Over the air (OTA) testing for 5G NR in far-field and near-field

Published on Jul 4, 2018

This video answers common questions that arise with 5G over the air testing. Where does the far-field start? Is the Fraunhofer distance “the” far-field distance? Do I need to know the antenna location inside the device under test? How can I measure under far-field conditions at near-field distances and remarkably reduce the test setup size?

Demystifying the 5G NR physical layer

Published on Dec 19, 2018

In December 2017, 3GPP officially released its first set of Release 15 specifications describing the physical layer for the 5G New Radio (NR) technology. Final specifications on the 5G NR protocol stack are still ongoing and will be completed by March 2018 with Abstract Syntax Notification One (ASN.1). Further corrections and clarifications in the physical layer specifications can be expected during this timeframe as 3GPP members start implementation and discover potential areas of improvement. Initial 5G NR deployments will focus on a non-standalone (NSA) mode. In the next step, 3GPP will specify a standalone (SA) mode by mid-2018. This webinar provides an overview of the latest 5G NR physical layer specification, discusses the test challenges related to 5G and demonstrates practical test solutions. The webinar concludes with a look at the challenges involved in SA operation.
Attendees will learn:
• 5G NR physical layer details
• How to test the 5G NR physical layer
• Challenges of the 5G NR standalone (SA) mode

Demystifying 5G – Clock input monitoring, holdover and relocking in 5G base stations

Published on Mar 6, 2019

Clock input monitoring and a corresponding holdover mechanism in case of a loss of the external clock signal are key functions in 5G base stations. The video demonstrates an IDT clock generator and shows the measurement of phase transient during a locked-holdover-relocking-locked cycle. A clock signal with a defined phase noise profile is used to emulate the effect of a real-world clock with a non-ideal phase noise performance.
