Research and Markets: Signals Ahead: Fifty Shades of MIMO

Research and Markets (http://www.researchandmarkets.com/research/2dqh4t/signals_ahead) has announced the addition of the "Signals Ahead: Fifty Shades of MIMO" report to their offering.

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 (News - Alert)) 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 t 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 (News - Alert) networks delivered outstanding end user throughput with TM 3 enabled.
• 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

Key Topics Covered:

1. Executive Summary

2. key conclusions and observations

3. Detailed results - low-speed mobility

4. Detailed results - stationary positions

5. Detailed results - high-speed vehicular

6. user Experience Tests (web browsing and YouTube (News - Alert))

7. Test Methodology

8. Final Thoughts

9. Appendix
