Finding MIMO - 4x4 MIMO Benchmark Study 2017 - Results from the Industry's First and Only Independent Performance Analysis - Research and MarketsResearch and Markets has announced the addition of the "Signals Ahead: Finding MIMO - 4x4 MIMO Benchmark Study" report to their offering. In this Signals Ahead report we provide the results from the industry's first and only independent performance analysis of 4x4 MIMO. For this study we used the T-Mobile commercial LTE (News - Alert) network in the Minneapolis market where Nokia is the infrastructure supplier. Our Approach We burned through more than 9 SIM cards (28GB each) while transferring data on Samsung (News - Alert) Galaxy S7 smartphones. We purchased one S7 from a T-Mobile store. This phone supported 4x4MIMO, 256-QAM, and a 4-way receive antenna architecture, as well as uplink64-QAM. We also purchased an unlocked S7 from a Best Buy store. This phone did not support any of these features. We configured the phones so that they only operated in Band 4 to maximize the potential use of 4x4 MIMO. We used the Datum application from Spirent (News - Alert) Communications in order to generate the downlink and uplink traffic. The Tease Over the course of all testing, including various morphologies and clusters of 4x4 and 2x2 MIMO sites, we observed that the median downlink data rate for the T-Mobile (News - Alert) S7 was 55 higher than the Best Buy S7. The Detailed Analysis In the main body of the report we analyze the performance differences between the two smartphones in excruciating detail. We quantify the incremental benefits of RI = 3/4 only, 256-QAM only, and mixed use of 256-QAM and RI = 3/4, as well as the benefits of a 4-way receive antenna architecture. What about Power? We quantify how the LTE-Advanced features that we tested impacted battery life, including normalized results which take into consideration differences in measured data speeds. What about the Uplink? Following our major study of uplink performance, based on testing in Seoul, South Korea, we revisit the impact of uplink 64-QAM on the uplink performance with a particular focus on the probability that the mobile device uses the higher modulation scheme. The findings are surprising. - SIGNALS AHEAD SUBSCRIPTION INFORMATION This report is included as part of a subscription to Signals Ahead or it can be purchased separately.
