Quantifying the Benefits of 3-Carrier CA with Support for up to 1 Gbps and the World's First 4-Carrier CA Network

In this Signals Ahead report we provide results from the industry's first independent and in-depth analysis of 4CCA and Gigabit LTE. For this study, we used the Telstra LTE network in Sydney, Australia.

Highlights of the Report include the following:

Our Thanks

This study could not have been done without the support of Accuver Americas who provided us with its XCAL data capture tool and XCAP post-processing software to collect and analyze the data.

Our Approach

We tested with the NETGEAR Nighthawk M1 mobile router, configured to work with 4CCA or in 3CCA mode by locking the device to Band 28 and Band 7 (2 channels). We used a high bandwidth FTP server within the operator's network (multi-session) to generate the data traffic.

The KPIs

Although data rates are interesting, and we include them in the report, we primarily focused on those performance metrics which reflect network efficiency. In particular, we looked at individual and combined use of 256-QAM and MIMO rank indicator (RI >=3). We included a wealth of other KPIs and their impact on performance in the study.

The Results

The results for 4CCA were pretty much as anticipated while we were greatly encouraged by our findings in the 3CCA tests, especially relative to our earlier studies we have done.
