By leveraging a suite of test solutions from Accuver, we conducted the industry's first independent analysis of a commercial LTE-Advanced network that supported three separate radio carriers (carrier aggregation).

We discuss the following:

  • We used two LG G Flex 2 smartphones powered by the Qualcomm Snapdragon 810 and X10 LTE modem. Huawei is the RAN infrastructure supplier in Seoul.
  • We conducted downlink throughput tests with one device and with two devices running in parallel, uplink throughput tests with a single smartphone, and user experience tests involving video-related applications.
  • We transferred more than 1 TB of data and observed¬† the highest downlink and uplink throughput that we have seen, thanks in part to the use of 40 MHz channel bandwidths in the downlink and 20 MHz channel bandwidths in the uplink.
  • The implied spectral efficiency based on RB normalized throughput from a single smartphone or the combined throughput from using two smartphones in parallel (no RB normalization and ignoring all other traffic in the network) was also stellar.
  • Strong network performance was largely due to the dense cell grid, although carrier aggregation played a secondary role.¬† The benefits of carrier aggregation are more obvious with applications that are bandwidth intensive – some applications benefit while others do not.
