Telstra prepares Australia for faster data speeds using 4G LTE-Advanced carrier aggregation

Telstra and Ericsson successfully demonstrated speeds up to 300Mbps with LTE Advanced Carrier Aggregation of 40MHz over 1800MHz band and 2600MHz bands on Telstra's live commercial network

Telstra prepares Australia for faster data speeds using 4G LTE-Advanced carrier aggregation

Ericsson says it has successfully supported Australian mobile operator Telstra in further enhancing its LTE Advanced (LTE-A) commercial service network. The two companies successfully demonstrated 300Mbps downlink speeds for a data transfer across Telstra's live network.

The demonstration used Ericsson's commercially released LTE Advanced software which aggregated 20MHz bandwidth within the 1800MHz band and 20MHz bandwidth within the 2600MHz band. The demonstration included downloading video content while measuring download throughput.

Mike Wright, Telstra executive director networks, said that the tests were an important foundational step towards being able to deploy Cat 6 LTE Advanced carrier aggregation when Telstra receives access to the 700Hz spectrum freed up by the Digital Dividend.

"The trials we conducted overnight demonstrate the ability to aggregate two channels of 20MHz spectrum on our commercial network. While the download speeds we achieved of 300Mbps are very impressive, for Telstra the main outcome is that we will be able to build out the capacity in our network to manage the future wireless data needs of our customers and continue to deliver them the most reliable network speeds and experience," said Wright.

Operators who want to offer a superior user experience need to build networks that provide both excellent voice and data coverage so that users can run all their favourite apps, including video, on smartphones and tablets.

LTE Advanced enables operators to deliver even higher performance mobile data transfer when customers need it. Operators will be able to provide subscribers throughout the network with twice the data speeds that they are receiving today by joining 20MHz in one band to 20MHz in another. In ideal conditions, with speeds of up to 300Mbps, consumers will be able to download a large 800MB file in approximately 21 seconds.

Thomas Norén, head of product area radio at Ericsson, said: "We are pleased to show with Telstra the network readiness of LTE Advanced carrier aggregation beyond 20MHz. The delivery of a superior mobile broadband experience remains key as smart device users depend more upon mobile broadband for everyday life. We also look forward to continuing our work with global chipset and handset manufacturers as the carrier aggregation ecosystem evolves further."

Ericsson claims market leadership in LTE. Today, 50% of the world's LTE smartphone traffic is served by Ericsson networks, which it says is more than double the traffic of its closest competitor. Ericsson said it also powers the world’s first two commercially launched LTE Advanced carrier aggregation networks in South Korea. More than 180 LTE RAN and evolved packet core networks have been delivered worldwide, of which more than 110 have gone live commercially.
