Huawei and Optus launch world's first LTE TDD advanced carrier aggregation
TT Correspondent |  |  24 Dec 2013

Huawei, a leading global information and communications technology (ICT) solutions provider, has announced that it had help Australian mobile operator Optus launch the world's first deployment of Carrier Aggregation (CA) technology on a live commercial LTE TDD (Long Term Evolution Time-Division) network with speeds hitting more than 160 Mb/s.
 
The live deployment has been rolled out across a number Optus' "4G Plus" sites in Melbourne, and follows an earlier trial of CA and other advanced technologies which saw speeds hit over 500 Mb/s on LTE TDD.
 
"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 CA deployment combines two 20MHz carriers on Optus' 2300 MHz 4G Plus spectrum. Initial tests have already shown speeds of above 160 Mb/s on 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 CA 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 520 Mb/s.
 
Globally, LTE TDD has been commercially deployed by 61 operators, with 12 of those operators combining both LTE FDD (LTE Frequency Division) and LTE TDD (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 LTE TDD devices, with some 80 devices available today and more in the pipeline for 2014.
