Huawei TD-LTE hits 160Mbps on Optus 4G Plus

Carrier aggregation network deployed across multiple sites Melbourne

Huawei has announced its deployment of carrier aggregation technology via live, commercial TD-LTE (Time-Division Long Term Evolution), with speeds reaching 160 megabits per second (Mbps; or 20 megabytes per second) on Optus’ 4G Plus network.

The live deployment has been rolled out across several of the telecommunications provider’s sites in Melbourne, following an earlier trial of carrier aggregation and other advanced technologies which saw speeds reach 500Mbps (62.5MBps) on TD-LTE.

“Carrier aggregation is an LTE-advanced technology which combines multiple spectrum bands; it’s the technological equivalent of adding extra lanes to a highway, allowing for higher-speed data traffic,” Huawei Australia chief technology officer (CTO), Peter Rossi, said.

“By combining two or more channels of carriers on existing live commercial LTE spectrum bands, Optus can dramatically increase throughput on its mobile data network.”

According to a statement from Huawei, the deployment combines two 20MHz carriers on Optus’ 2300MHz 4G Plus spectrum.

The vendor expects to launch mobile broadband devices compatible with carrier aggregation (known as Cat-6 TD-LTE) in 2014. Globally, TD-LTE has been commercially deployed by 61 operators, with 12 of those combining both FD-LTE and TD-LTE. This includes Optus. Huawei’s technology is being used in 50 deployments.

Additional carrier aggregation tests have been conducted by Huawei and Optus in St Marys (in Sydney’s west), combining four 20MHz carriers for a total of 80MHz on the 2300MHz band. Results are claimed to have reached more than 520Mbps (65MBps).
