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):
