VoLTE Benchmark Study 2016 EVS and AMR-WB in a commercial LTE network - Research and Markets


Research and Markets has announced the addition of the "Signals Ahead: VoLTE Benchmark Study Part 6 - EVS and AMR-WB in a commercial LTE network" report to their offering.

In this Signals Ahead report we provide part two of the two-part study of the new EVS voice codec and how it compares with AMR-WB. For this independent study, we purchased four commercial smartphones (LG G5) and used the T-Mobile (News - Alert) USA network.

Highlights of the Report include the following:

Better Voice Quality.

True to its word, EVS can deliver better voice quality than AMR-WB. With more challenging conditions and with a noisier channel (background crowd noise) the delta can become significant. We quantify ad substantiate this statement with innumerable test results and figures in the main body of the report.



More Efficient. In most of the tests, EVS was more efficient than AMR-WB with the differences generally even more significant in the uplink direction.

What about Power?


As far as we could determine, there were very little differences in the power/current consumption of the two codecs. To the extent there are differences, which we could not clearly identify, we argue that in the big picture it doesn't matter.

1.0 Executive Summary
