Australia’s Telstra and Swedish vendor Ericsson have demonstrated what they termed the ‘next step in carrier aggregation’, with the duo for the first time combining five carriers to achieve download speeds of up to 1Gbps over a live commercial mobile network. In the technology demonstration the pair said they achieved downlink speeds in excess of 950Mbps with a User Datagram Protocol (UDP) speed test application by aggregating 100MHz of spectrum across Telstra’s spectrum holdings in the 700MHz, 1800MHz, 2100MHz and 2600MHz (2×20MHz) bands. In announcing the development, the companies claimed it represented the third ‘world-first capability milestone’ that they had achieved together this year, having previously demonstrated downlink speeds of 450Mbps and 600Mbps in February and September, respectively.
Commenting on this latest technology test, Telstra’s networks general managing director Mike Wright was cited as saying: ‘Demand for a superior user experience is ever increasing as customers are “always-on” and have access to new and advanced technologies. We are thrilled to be able to demonstrate this capability in our network thanks to our ongoing partnership with Ericsson. The demonstration of 1Gbps end-to-end capability shows the advanced state of these standards and our ability to rapidly bring them into commercial service in order to deliver increased capacity in our network to meet growing demand.’
