Ericsson, Telstra Demonstrate LTE-A CA Down Under
Ericsson is demonstrating one of the key features of LTE-Advanced in Australia with an announcement today that provider Telstra has used carrier aggregation on 1800 MHz and 900 MHz bands.
According to a press release, Telstra was able to transfer data across its live network on the combined bands on a number of sites in Queensland (Australia) carrying commercial traffic.
Carrier aggregation allows operators to combine multiple spectrum bands to enable higher mobile broadband download speeds.
Håkan Eriksson, head of Ericsson Australia, New Zealand and Fiji, said that when they company gets access to 700MHz spectrum in 2015, Ericsson intends to deploy the next-generation of LTE-Advanced by combining larger blocks of spectrum in the 700MHz and 1800MHz bands to deliver theoretical speeds in the range of 300Mbps.
"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," Eriksson said in a statement. "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. The company supported LG U+ in South Korea to commercially launch LTE-Advanced using both 2100MHz and 850MHz bands.
