The Australian operator Telstra has successfully used LTE-Advanced by combining live traffic over the 1800MHz and the 900MHz spectrum bands. According to the operator it was the world’s first call on the two combined spectrum bands.
The LTE-Advanced test was carried out on July 31, when Telstra transferred data across its live network on a number of sites in Queensland carrying commercial traffic. Telstra was supported by Ericsson.
Håkan Eriksson, Head of Ericsson Australia, New Zealand and Fiji, thinks that many operators will be watching the Australian deployment of LTE-Advanced on multiple spectrum bands. “Because many operators have spectrum available in the 1800MHz and 900MHz bands as they migrate subscribers from 2G to 3G or 4G.”
By combining multiple spectrum bands operators are able to offer higher broadband speeds and to make the most of their existing spectrum assets.
Mike Wright, Executive Director Networks at Telstra, obviously is happy with the newly used LTE technology. “When we get access to the 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”, he explained.
Telstra says it needs LTE-Advanced to continue providing additional capacity and high-quality service because the number of LTE subscribers is growing extremely fast in Australia. In six months the number of subscribers at the Telstra LTE service grew with 900.000 to nearly 3 million.
