Research and Markets: Signals Ahead: LTE Band 7 versus LTE Band 4

Research and Markets (http://www.researchandmarkets.com/research/qdhsss/signals_ahead) has announced the addition of the "Signals Ahead: LTE Band 7 versus LTE Band 4 - GAME ON!" report to their offering. This report analyzes LTE Band 7 and LTE Band 4 performance characteristics. The extensive analysis, which includes in-building and outdoor test results, leveraged one of the very few networks in the world where LTE is deployed in Band 7 and Band 4 by the same operator in the same market and at virtually every single cell site with a shared antenna configuration. In order to answer the all-important questions pertaining to a dual-band strategy, we analyzed several underlying downlink and uplink KPIs. We also correlated these KPIs to more basic performance characteristics, such as throughput. The downlink KPIs for both the in-building and outdoor drive testing include the following: - RSRP (average and at edge of cell) - Downlink Path Loss (average and at edge of cell) - SINR - 64 QAM Utilization - Rank Indicator 2 and Rank Indicator 1 Availability - PDSCH Throughput (average and at edge of cell) - Number of Assigned Resource Blocks The uplink KPIs for both the in-building and outdoor drive testing include the following: - PUSCH Transmit Power - Power Headroom - PUSCH Throughput - Number of Assigned Resource Blocks Handover/Interoperability analysis includes the following: - IP Layer Handover Latency - Band 7 to Band 4 and Band 4 to Band 7 - Handover Success/Failure Rate - RSRP at Inter-band Handovers - Cell Coverage Area Types of Figures include the following (we also include numerous geo-plots of KPIs using Google Earth as well as the in-building mapping capabilities of the XCAL-M drive test solution): Probability Plots - PDSCH and PUSCH Throughput - SINR - 64 QAM - RSRP - Downlink Path Loss - PUSCH Transmit Power - Power Headroom - DL/UL Resource Block Allocation Scatter Plots - RSRP versus PDSCH Throughput (average and edge of cell) - RSRP versus PUSCH Throughput (average and edge of cell) - Power Headroom versus PUSCH Throughput Time Series Plots - Uplink Resource Blocks versus PUSCH Throughput during Handovers - RSRP versus PDSCH Throughput - RSRP versus PUSCH Throughput - PDSCH Throughput and Downlink RBs during a Handover Key Topics Covered: 1.0 Executive Summary 2.0 Key Conclusions and Observations 3.0 Band 4 and Band 7 Downlink and Uplink Performance Analysis - overall results 4.0 Detailed Band 7 and Band 4 Downlink Performance Analysis - including specific test scenarios 5.0 Detailed Band 4 and Band 7 Uplink Performance Analysis - specific test scenarios 6.0 Band 7 and Band 4 Interoperability and Handover Analysis 7.0 Band 7 and Band 4 In-building Performance Analysis 8.0 Test Methodology 9.0 Conclusions 10.0 Appendix For more information visit http://www.researchandmarkets.com/research/qdhsss/signals_ahead Web 2.0 Latest News
