Australian telecommunications provider Telstra has used Ericsson technology to become the first operator to use LTE-Advanced (LTE-A) carrier aggregation technology on the 1800MHz and 900MHz spectrum bands on a commercial network.
This world’s first commercial LTE-Advanced call on 1800MHz and 90MHz took place on 31 July 2013, when Telstra transferred data across its live network on a number of sites in Queensland (Australia) carrying commercial traffic.
LTE Carrier Aggregation is the next step in the evolution of high-speed mobile broadband services, enabling operators to make the most of their existing spectrum assets by combining multiple spectrum bands to enable higher mobile broadband download speeds.
Mike Wright, executive director networks, Telstra, said: "Telstra's LTE subscriber numbers are growing dramatically, with nearly 3 million subscribers currently using the LTE network, up from 2.1 million six months ago. The capacity, higher data speeds and efficiencies provided by LTE-Advanced will help manage growth in data traffic as more customers choose our network. This will allow us to continue providing additional capacity and high-quality service, and we look forward to working with Ericsson to make this happen."
"When we get access to 700MHz spectrum in 2015 we also intend to deploy the next-generation of LTE-Advanced by combining larger blocks of spectrum in the 700MHz and 1800MHz bands to deliver blistering peak speeds in the theoretical range of 300Mbps," said Wright.
Håkan Eriksson, head of Ericsson Australia, New Zealand and Fiji, said: "Across the region and the globe, many operators have spectrum available in the 1800MHz and 900MHz bands as they migrate subscribers from 2G to 3G or 4G. Many operators will be watching the Australian deployment of LTE-Advanced on these spectrum bands."
Ericsson is supporting the deployment of LTE-Advanced Carrier Aggregation on other spectrum bands in other countries such as South Korea. On 18 July, for instance, Ericsson supported LG U+ in South Korea to commercially launch LTE-Advanced using both 2100MHz and 850MHz bands.
