Optus Launches LTE TDD Advanced Carrier Aggregation with Huawei

Optus launched Carrier Aggregation (CA) technology on its live commercial LTE TDD (Long Term Evolution Time-Division) network  in Australia.

The deployment, which was carried out in partnership with Huawei, combines two 20MHz carriers on Optus' 2300 MHz 4G Plus spectrum. Initial tests have already shown speeds of above 160 Mbps on a single device.  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 Mbps 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."

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 Mbps.

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


  • 4×4 MIMO (multi-input-multi-output), which delivered 125 Mbps 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 18 Mbps to 30 Mbps.
  • Circuit-Switched (CS) Fallback, which allows Packet-Switched LTE 4G connections to revert to CS GSM/UMTS 3G networks for voice calls

Huawei expects to launch mobile broadband devices compatible with CA (known as Cat-6 TD-LTE) in 2014.

ZTE Completes End-to-End VoTD-LTE Call with China Mobile

ZTE completed an end-to-end voice-over TD-LTE (VoTD-LTE) call in partnership with China Mobile and Marvell Technology Group.

ZTE said the test represents the industry's first end-to-end VoTD-LTE call.  The test was conducted on China Mobile’s network in Guangzhou, using 5-mode, 13-band smartphones powered by Marvell’s chipsets.

At present, there are three main methods to offer voice services to LTE users: CS Fall Back (CSFB), dual standby and VoLTE. The CSFB solution requires operators to hand off voice calls to slower 2G or 3G networks. The dual standby solution requires terminals to support the 2G/3G and 4G services simultaneously, with the 2G/3G network dedicated to provide voice services. VoLTE is an IMS-based voice service, with voice transmitted as IP data, and can be entirely supported by the LTE network, without 2G or 3G networks. Compared with the CSFB and dual standby solutions, the VoLTE solution offers superior voice quality and lower latency, with improved energy consumption for terminals, delivering a better user experience for 4G services.

ZTE said this testing will help accelerate the adoption of voice services on TD-LTE networks, and usher in the TD-LTE full-service era, aligning the TD-LTE industry with the FDD-LTE industry. As the development of mobile devices, TD-LTE wireless networks and IMS platforms become more mature, more VoLTE services will be deployed.
