Australia’s Telstra has announced that it achieved download speeds of 300Mbps, having used Carrier Aggregation technology over its live 4G network. In a blog post detailing the development, the operator’s director of networks Mike Wright confirmed that the trial was conducted using a commercial test device and aggregating 20MHz bandwidth within the 1800MHz spectrum band and 20MHz bandwidth within the 2600MHz band. The executive did, however, highlight the fact that while such speeds were ‘impressive’, downlink rates available to consumers are likely to be lower. Nonetheless, Mr Wright pointed to the importance of the tests with regards to a commercial deployment of LTE-Advanced (LTE-A) technology, saying: ‘These trials are important for another reason as they build on our earlier LTE-A work and set us up to continue to deliver a reliable network experience and more reliable speeds into the future. We have all seen around the world what happens when operators can’t keep up with customer demand. Without a strong, multi-year strategy the rapid rate of data growth would quickly swamp any new network rollout.’
As previously reported by CommsUpdate, in August 2013 Swedish vendor Ericsson claimed that Telstra had become the first to use the LTE-A Carrier Aggregation technology on 900MHz and 1800MHz spectrum bands on a commercial network. Noting that milestone was actually achieved on 31 July 2013, it was revealed that Telstra at that date transferred data across its live network on a number of sites in Queensland (Australia) carrying commercial traffic.
