Huawei and Optus launch world-first TD-LTE Advanced Carrier Aggregation network

TD-LTE hits speeds over 160Mbps on live Optus 4G Plus network in Melbourne

Huawei and Optus have announced the world’s first deployment of Carrier Aggregation technology on a live, commercial TD-LTE network, with speeds hitting more than 160Mbps. The live deployment has been rolled out across a number Optus’ 4G Plus sites in Melbourne, and follows an earlier trial of Carrier Aggregation and other advanced technologies which saw speeds hit over 500Mbps on TD-LTE (Time-Division Long Term Evolution).

“Carrier Aggregation is an LTE-Advanced technology which combines multiple spectrum bands – it’s the technological equivalent adding extra lanes to a highway, allowing for higher-speed data traffic,” said Huawei Australia CTO Peter Rossi. “This project adds to Huawei’s long list of world-first technology breakthroughs. By combining two or more channels or ‘carriers’ on existing live commercial LTE spectrum bands, Optus can dramatically increase throughput on its mobile data network.”

The Carrier Aggregation deployment combines two 20MHz carriers on Optus’ 2300 MHz 4G Plus spectrum. Initial tests have already shown speeds of above 160Mbpson a single device.

“Introducing LTE carrier aggregation into a live, commercial TD-LTE network is a world first and an exciting technology innovation for us,” said Vic McClelland, Managing Director of Optus Networks.

“What’s more exciting  is that Optus customers  will soon be able to experience the faster speeds and greater capacity our 4G Plus network and carrier aggregation can provide. With Australians becoming increasingly mobile data hungry, this innovation puts Optus in a great position to provide the network capacity needed to handle this growing data demand.”

Additional Carrier Aggregation tests have been conducted by Huawei and Optus in St Marys, west of Sydney, combining four 20MHz carriers for a total of 80MHz on the 2300MHz band to deliver mobile broadband speeds of over 520Mbps.

The same trial also demonstrated a number of additional LTE technologies including:

· 4*4 MIMO (multi-input-multi-output), which delivered 125Mbps speeds on a single 20MHz carrier

· Beamforming, where the network intelligently forms radio signals to deliver the best experience to users as they move around a cell coverage area. Beamforming tests showed a 67% improvement in data speeds at the edge of a cell, from 18Mbps to 30Mbps.

· CS Fallback, which allows Packet-Switched LTE connections to revert to Circuit-Switched GSM/UMTS networks for voice calls

Huawei 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 operators combining both FD-LTE (Frequency Division LTE) and TD-LTE (including Optus). Of the 61 commercial networks, Huawei’s technology is being used in 50 deployments – by far the greatest market share of any network vendor. Huawei is also the market leader in TD-LTE devices, with some 80 devices available today and more in the pipeline for 2014.
