2019 Research Report on 5G - Operators are Taking Advantage of LAA

DUBLIN, May 13, 2019 /PRNewswire/ -- The "5G: The Greatest Show On Earth! Volume 3: Vikings Vs. Bears" report has been added to ResearchAndMarkets.com's offering.

The author conducted a benchmark study of the Verizon Wireless 5G NR networks in Minneapolis and Chicago. Although data speeds are interesting, the author focused their efforts on metrics that have far more implications on the long-term prospects for 5G NR, operating in millimetre wave frequencies and supporting eMBB use cases. This work also includes the Interdependencies between 5G NR and LTE.

Highlights of the Report:

    --  Thanks - This study was done in collaboration with Accuver Americas,
        Rohde & Schwarz, and Spirent Communications who provided the author with
        their respective test equipment, which is identified in the report. The
        author did all the testing and analysis of the data and they are solely
        responsible for the commentary in the report.
    --  Methodology - The author captured chipset diagnostic messages from up to
        two Motorola Z3 smartphones with/without the 5G Moto Mod, as well as
        scanner information in the two networks. Using sustained, high bandwidth
        data transfers (UDP and TCP), they performed walk tests and drive tests,
        not to mention sensitivity studies involving grip, device positioning,
        and sudden turns. We also did multiple user experience tests involving
        popular applications to determine if the applications and services took
        full advantage of the network capabilities.
    --  The Results - Although the author observed sustained PDSCH Layer data
        speeds of 1.1 to 1.2 Gbps on numerous occasions and a peak data speed of
        at least 1.5 Gbps, they believe the long-term prospects for millimetre
        wave are better defined by parameters, such as BRSRP and BSINR, and how
        these parameters are impacted by distance as well as
        near/non-line-of-site conditions. RF reflections remain alive and well.
    --  A bit "Wonky" - Although the network performance was a bit wonky, it
        wasn't a direct result of millimetre wave, or at least the issues the
        author documented can easily be overcome. Device/modem stability,
        support for beam management, increased utilization and more efficient
        use of the 5G NR radio channels top the list, as does improving the
        interdependencies with the LTE network. The use of 1,024 element arrays
        in the gNB radio and/or the mixed use of wide beams and narrow beams
        will further improve coverage and capacity.
    --  The Importance of LTE - When operators deploy 5G NR FR2, they frequently
        use a small cell architecture. As the author witnessed in their tests,
        and in an earlier series of small cell studies, there is a substantial
        capacity gain with LTE and small cells. Furthermore, operators are also
        taking advantage of LAA. In the case of Verizon, the Motorola Z3 (w/ 5G
        Moto Mod) simultaneously used five LTE carriers, including three
        unlicensed bands in Chicago.
    --  A Paradigm Shift - 5G NR FR2 doesn't need to provide ubiquitous
        coverage, especially once operators deploy 5G NR in cellular bands and
        incorporate carrier aggregation. Given the results of user experience
        tests, it is clear that 5G NR FR2 isn't about peak speeds to individual
        users, but the total capacity that it offers.
