Dublin, July 12, 2023 (GLOBE NEWSWIRE) -- The "5G NR Benchmark Study Vol 33: VZ + Samsung MU-MIMO" report has been added to ResearchAndMarkets.com's offering.
This endeavor involves collaborations with Accuver Americas and Spirent Communications to conduct an independent benchmark study of 5G MU-MIMO, using Verizon's commercial 5G network in Memphis, TN, where Samsung is the RAN infrastructure supplier.
Highlights of the Report include the following:
Acknowledgements
The publisher did this study in collaboration with Accuver Americas (XCAL5 and XCAP) and Spirent Communications (Umetrix Data). SRG is responsible for the data collection and all analysis and commentary provided in this report.
Methodology
The publisher primarily tested at one cell site (3 sectors) which supported MU-MIMO, 100 MHz channel bandwidth (versus the typical 60 MHz that VZ has deployed), and 10 Gbps backhaul. They did stationary testing with four Galaxy S22 smartphones placed in vehicles in various locations within the sector and included 2 different drive test routes to gauge the impact of mobility on MU-MIMO and SRS performance. They estimate ~15 different device placements with stationary tests.
Key Differences
To the publisher's surprise, the virtualized RAN (vRAN) supported 16 downlink MIMO layers and 8 uplink MIMO layers. The publisher didn't realize this capability until after we started analyzing the results in detail. The publisher didn't test uplink MU-MIMO while with only 4 smartphones, the results obtained likely understate the full MU-MIMO potential of the network.
The Results are In
Without getting into specifics, the publisher observed near-perfect reuse of network resources (RBs) in most tests. Additionally, the aggregate MIMO layer count was frequently close to 8 layers across all smartphones after adjusting for RB use/reuse, and reaching at least 12 layers in some cases.
Although MCS dropped in most tests, the net effect was still up to a high double-digit increase in sector capacity. The results with devices placed close together wasn't what we were hoping for since the sharp drop in MCS more than offset the high RB reuse and higher total MIMO layer count versus SU-MIMO.
FWA
FWA is THE use case for MU-MIMO. In addition to the need for increased low-cost capacity due to the usage profile of FWA, FWA benefits from relying on stationary devices (CPEs), which generally tends to result in better MU-MIMO results.
Around the Corner
Future topics include Open RAN (multiple studies, including scheduler efficiency) and uplink 5G carrier aggregation (FR1), in no particular order.
