    Demystifying 5G – Signal analysis of Verizon Wireless 5G waveforms

    Published on Nov 15, 2016

    The analysis of a 5G signal following the Verizon Wireless 5G specification is demonstrated in this video. The R&S®SMW200A vector signal generator transmits a 28 GHz 5G signal that is captured with the R&S®FSW signal and spectrum analyzer. For postprocessing, the R&S®FS-K96PC OFDM vector signal analysis software from Rohde & Schwarz is applied.

    Demystifying 5G – 5G New Radio (NR) waveform generation

    Published on Nov 17, 2016

    How to generate a 5G New Radio (NR) waveform? This video demonstrates the generation of a 5G NR waveform using the R&S®SMW200A vector signal generator and the R&S®SMW-K114 5G air interface candidates option from Rohde & Schwarz. In this example the 5G waveform uses one of the physical layer parameterization currently discussed in 3GPP RAN1.

    Accurate 5G antenna characterization up to mmWave presented at GSMA MWC 2017

    Published on Mar 16, 2017

    Rohde & Schwarz demonstrated 5G antenna testing up to mmWave frequencies in a portable shielded chamber at the GSMA Mobile World Congress 2017 in Barcelona. The scalable R&S®ATS1000 antenna test system supports 3D antenna characterization, beamforming testing as well as near-field to far-field transformation. The system even enables far-field measurements for 5G frequencies such as 28 GHz and 39 GHz in a compact setup.

    Be first for 5G signal generation and analysis presented at GSMA MWC 2017

    Published on Mar 16, 2017

    Rohde & Schwarz demonstrated 5G component characterization at 28 GHz at the GSMA Mobile World Congress 2017 in Barcelona. The R&S®SMW200A vector signal generator supports signal generation according to the 28 GHz pre-5G specification available at 5GTF. Combined with the R&S®FSW signal and spectrum analyzer supporting an internal 1.2 GHz analysis bandwidth makes this setup ideal for in-depth component characterization such as for 28 GHz power amplifier development.

    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. This puts some significant challenges on system design to enable full mobility. In this video we explore the fundamentals for mobility in a cellular system and show how (pre-)5G and 5G systems eventually tackle this challenge.

    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
