Telstra, an Australian telco, has claimed to set a world record by displaying speed of 450 Mbps over LTE Advanced Carrier Aggregation (LTE-A) on its mobile network.

Telstra achieved this speed and confirmed it was possible by experimenting on two LTE-A combinations of 1800 MHz and 2600MHz bands. The speed is three times faster than Telstra's current network speed -150 Mbps or as the company published that it is 800 times faster than the speeds first experienced with 56K dial up.

Working with Ericsson, Telstra combined 20 MHz of each operating channel on the 2600 MHz bandwidth with the existing 20 MHz of operating channel on the 1800 MHz spectrum. This was part of the installation of equipment for two new 4G frequency division channels. By doing this, three simultaneous side by side paths were created for data to travel to their operational core network.

To achieve the speeds, an advanced Category 9 engineering device capable of combining the three channels was also used. This was the first time in the world that such speeds have been achieved by combining three data channels on an LTE-A network, according to Telstra.

Group Managing Director for Telstra networks, Mike Wright, commented, "Conducting this type of test is a significant step in the network engineering and development process."

"It is essential for us to see how this type of technology works in the live network and understand what needs to be done to continue to absorb the exploding demand in mobile broadband and offer an exceptional customer experience."

Telstra is currently holding the largest APT700 MHz and 2600 MHz spectrum in Australia and promises to offer the customers improved and faster speeds.
