Telstra Hits 450Mbps in Mobile Data Download Speeds over 4G Network
Published on: 15th May 2014
Australia's Telstra has demonstrated mobile download speeds of 450Mbps by use of carrier aggregation on its LTE A network.
The mobile network carried out a trial combination of 1800MHz and 2600MHz bands for the demonstration.
Telstra worked with Ericsson to install equipment for two new 4G Frequency Division Duplexing (FDD) channels of 20MHz bandwidth each on the 2600MHz spectrum band (40MHz FDD), aggregated with their live 20MHz of 4G on the 1800MHz band.
The result was three simultaneous side-by-side paths for the data to travel through to the operational core network. Telstra also used an advanced prototype Cat 9 engineering device that could combine the three channels to achieve these speeds.
Mike Wright, Group Managing Director Telstra Networks said the test was designed to take the network capability for a spin and learn what happens when you lift performance to these types of speeds.
"This test allows us to see how the technology works ahead of when we make a future investment in it," Mr Wright said. "The typical speeds achievable at a commercial level will be lower in practice and while individual users may not consume all of this bandwidth, the ability to effectively triple the typical user speeds possible on Telstra's 4G service today, means we can carry a huge amount of future traffic demand shared across many users."
The test also confirmed Telstra's ability to bring together three blocks of spectrum to increase the capacity and speeds delivered over the mobile network.
Deployment to customers remains a few years away and it is expected the initial implementation may look slightly different to today's test, with plans to combine one block each of 1800MHz, APT700MHz and 2600MHz spectrum.
