Snapdragon 810 shows mind-boggling LTE-A Carrier Aggregation speeds

Mobile technology is designed to help us stay connected, but each device we connect puts more strain on our networks. Thankfully, Qualcomm Technologies, and other mobile industry leaders, are always working to make sure there’s more than enough bandwidth for everybody (and everything). LTE-Advanced with 3x Carrier Aggregation (CA), which can support download speeds of up to 450 Mbps over three 20MHz LTE carriers, is a great example of that work.

A new report by Signals Research Group describes some pretty remarkable (or, as the report says, “mind-boggling”) findings on the performance of the LG U+ LTE-Advanced 300 Mbps commercial network in Seoul, South Korea. The tests used a pair of LG G Flex2 smartphones, powered by Qualcomm Snapdragon 810 processors.

How fast was it? Very. The average download speed was 158 Mbps, and the peak data rate reached was a lightning-fast 296.5 Mbps. The average uplink data rate was 44.4 Mbps, but topped out at 48.8 Mbps.

Because Snapdragon 810 processors feature integrated LTE-Advanced multimode modems, which support 3x CA, devices built around the system are ideal benchmarks for gauging the LG U+ 3x CA network.

Check out this video for a crash course on the benefits of LTE-Advanced Carrier Aggregation:

The tests were conducted day and night—in two separate districts, as well as on the subway—over the course of four days, transferring a total of 1.02 TB of data over the network. They chose Seoul because, with the launch of the new LG U+ LTE-Advanced 300Mbps network, South Korea has some of the fastest connectivity in the world.

The LG G Flex2 is just one of a number of devices which features support for 3x Carrier Aggregation enabled by the Qualcomm Snapdragon 810 processor. You can find out more about the Signal Research Group at their website.
