OTA performance benchmark study of leading smartphones

In our 17th Chips and Salsa, we provide results from the industry’s first independent Over-the-Air (OTA) benchmark study of commercially-procured LTE mobile devices.

For this study we continued our multi-year collaboration with Spirent Communications, who provided us with a full suite of test equipment and engineering support to conduct the tests. ETS-Lindgren joined us in the collaborative effort by providing its anechoic chamber as well as providing access to the company’s facilities in Austin, Texas.

  • We benchmarked five commercially procured smartphone – the LG G2, the Samsung Galaxy S4, the Samsung Galaxy Note II, the HTC One, and the Motorola Moto X.
  • Each smartphone was tested at twelve different angles (0 to 330 in 30 degree increments) with the SCME UMi (Urban Micro) fading conditions across a wide range of power levels with both correlated and uncorrelated signals. In total, each device was tested for at least 420 minutes in the chamber.
  • The top performing smartphone won by a country mile, outperforming the second best performing smartphone by more than 35% across all tests. At lower power levels it was able to sustain a data call as much as 9 dB lower than the other devices that we tested.
  • We include results from some sensitivity studies that look at the incremental impact of MIMO (TM3) versus transmit diversity (TM2) as well as the performance impact of introducing a protective cover.
