Demystifying 5G - Enable mobility in 5G systems

Published on Mar 23, 2017

Dual connectivity is the method of choice for (pre-)5G and 5G NR to enable full mobility using LTE as an anchor technology. However, there are quite some differences between the 3GPP-based version of dual connectivity and how (pre-)5G standards are planning to utilize this methodology. In this video we explore the differences between the two.

Demystifying 5G - How mobile is 5G at mmWave frequencies?

Published on Mar 23, 2017

mmWave frequencies provide quite some challenges, including a much higher Doppler shift compared to sub-6 GHz frequencies when targeting higher speeds.

Demystifying 5G and the evolution to massive MIMO for increased capacity and profit

Published on Mar 28, 2017

What is the motivation for 5G from an operator’s perspective? This webinar explores two critical technologies for evolving 4G into 5G: virtualization of the baseband processing and massive MIMO antenna arrays. Baseband virtualization can result in 50 % lower operating expenses (OPEX) for cellular operators while increasing network capacity by implementing enhanced coordinated multipoint (CoMP). Massive MIMO replaces existing separate radio units and passive antennas with an integrated transceiver plus antenna arrays to create an active antenna system with the coexistence of beamforming and MU-MIMO architectures. While both technologies are considered critical for 5G, they are already being developed for integration into existing TD-LTE networks. In this webinar, the challenges facing massive MIMO deployment and measurement will be briefly addressed, and over-the-air (OTA) measurements for 5G mmWave radio equipment based on Rohde & Schwarz benchtop OTA solutions will be demonstrated.

What you will learn:
- Massive MIMO concept, application and challenges
- Measurement of 5G antenna radiation pattern using the R&S®DST200 RF diagnostic chamber
- Realtime beamsteering measurements for mmWave systems with the OTA power measurement solution

Demystifying 5G - Full test support of Verizon Wireless 5GTF specification

Published on Jul 26, 2017

In July 2016, Verizon Wireless and its partners published a 5G technology standard based on 3GPP's Release 12 specification for LTE. Known as 5GTF, the specification targets Fixed Wireless Access (FWA) as application scenario with no mobility. The targeted frequency band is 28 GHz. Rohde & Schwarz implemented this specification into its signal generator and spectrum analyzer solutions to allow early adaptors the testing of mmWave RF components, RF frontends, 5G remote radio heads (RRH), customer premise equipment (CPE) and modem implementations. This video provides an overview on 5GTF test solutions based on the R&S SMW200A vector signal generator and the R&S FSW signal and spectrum analyzer from Rohde & Schwarz.

Demystifying 5G – V5GTF crest factor reduction (CFR) - a simple way out?

Published on Jul 28, 2017

A high peak-to-average power ratio (PAPR) is not beneficial as it challenges the non-linear power amplifier operation close to compression for maximum efficiency. A possible way out is to apply crest factor reduction (CFR) techniques such as to clip high signal peaks. This video demonstrates a simple method to clip (any) waveform, including the Verizon Wireless 5GTF signal, using software tools for signal generation and analysis from Rohde & Schwarz.

Demystifying 5G - Testing the true performance of ADCs

Published on Sep 4, 2017

Enhanced mobile broadband (eMBB), one of the 5G use cases, targets wider bandwidths at frequencies in the mmWave range to achieve the promised Gbps experience. This requires new, high-resolution digital-to-analog converters (DACs) and analog-to-digital converters (ADCs), such as the recently launched ADC12DJ3200 from Texas Instruments. They demand highest signal purity for testing their true performance. The R&S SMA100B RF and microwave analog signal generator from Rohde & Schwarz combines highest output power, lowest phase noise and lowest wideband noise making it ideal for high-resolution ADC/DAC testing as demonstrated in this video.

Published on Nov 22, 2017

3GPP's 5G NR will support frequency ranges up to 52.6 GHz, but initial 5G designs will use frequencies below 6 GHz with focus on 3.5 GHz. For sub-6 GHz carrier frequencies, 3GPP currently discusses a maximum bandwidth per component carrier of 100 MHz. The R&S CMW100 communications manufacturing test set with a supported bandwidth of 160 MHz is ready for testing initial 5G NR sub-6 GHz wireless devices in production. The video demonstrates a typical manufacturing test case using a 5G NR-like waveform.

Demystifying 5G - Minimizing the impact of accessories when testing 5G RF components

Published on Nov 24, 2017

Testing RF components, such as power amplifiers and filters, or prototype transceiver modules becomes much more complex with higher frequencies, particularly in the mmWave range used for 5G. Calibrating the test equipment to minimize their impact was extensive and time-consuming, and a change in power level or frequency range often required a recalibration. The R&S SMW200A vector signal analyzer and R&S FSW signal and spectrum analyzer from Rohde & Schwarz make the calibration of the signal path towards the device under test (DUT) simple and easy, as demonstrated in this video.
