This report analyzes the incremental benefits of MIMO (Multiple Input, Multiple Output), specifically Transmission Mode 3 (TM 3), in commercial LTE networks. The results are based on testing in LTE networks from two different operators (Knoxville, TN and Santa Clara, CA) with TM 3 enabled and with the network specially configured to only support Transmission Mode 2. In addition to adhering to a fairly rigorous test methodology, the analysis of the data included mapping the results to a common set of KPIs – primarily device-reported SINR and RSRP, to ensure an apples-to-apples comparison.

Key Observations Include The Following:

    --  Both LTE networks delivered outstanding end user throughput with TM 3
    --  Average throughput of 12.91 Mbps in a 2 x 5 MHz network in Knoxville,
        TN; at least 20 Mbps for 21.6% of the time
    --  Average throughput of 24.71 Mbps in a 2 x 10 MHz network in Santa Clara,
        CA; at least 40 Mbps for 18.5% of the time
    --  MIMO can double the end user throughput, but the gains are generally far
        more modest with no benefit, and even a negative impact, possible.
    --  Observed doubling of throughput in both markets with ideal conditions
        (SINR >> 25 dB)
    --  At least 40% of the time the availability of TM 3 can increase the end
        user throughput by at least 20%
    --  Conversely, at least 50% of the time, the availability of TM 3 would
        only have a modest impact on throughput (-5%-10%), at best, with
        negative gains possible
