Australian mobile operator Telstra has announced successful live demonstration of 450Mbps network speed using LTE Advanced Carrier Aggregation across a trial combination of 1800MHz and 2600MHz bands.

Australian mobile operator Telstra has announced successful live demonstration of 450Mbps network speed using LTE Advanced Carrier Aggregation across a trial combination of 1800MHz and 2600MHz bands.  These speeds, achieved in testing, are three times faster than the theoretical peak network speeds that Telstra currently offers on 4G network.

Telstra worked with network partner Ericsson to install equipment for two new 4G Frequency Division Duplexing (FDD) channels of 20MHz bandwidth each on the 2600MHz spectrum band (40MHz FDD), aggregated with its live 20MHz of 4G on the 1800MHz band. The result was three simultaneous side-by-side paths for the data to travel through to the operational core network.

Telstra also used an advanced prototype Cat 9 engineering device that could combine the three channels to achieve these speeds.
