Telstra has claimed another world first by completing a 2Gbps capable LTE data call over its commercial network.
The call took place in Toowoomba, where Telstra set its 5G network live last month, in partnership with technology collaborators Ericsson and Qualcomm.
To achieve 2Gbps speeds, Telstra aggregated five LTE carriers across three frequency bands, each using 4x4 MIMO and 256 QAM technologies. The call itself used one of Qualcomm’s mobile test devices connected with a Qualcomm Snapdragon x24 LTE modem and an Ericsson Radio System which ran all five carriers.
“Success in 5G will depend on strong underlying 4G technology, and this world first call over Telstra’s commercial network is an important step forward in the development of 5G,” Telstra executive director of network and infrastructure engineering Channa Seneviratne said.
“We now have the commercial end-to-end network capability to deliver such world-leading LTE speeds and will now begin to deploy this technology in our mobile network to support even greater capacity and faster mobile speeds for our customers where it is needed most.”
The latest breakthrough follows on from earlier this year when Telstra trialled the 2Gbps technology at Mobile World Congress in Barcelona.
Telstra only launched gigabit speeds on 4G in select CBD zones early last year. The telco hopes to bring 2Gbps speeds to “high traffic” portions of its network at some point this year. Achieving those speeds will require a device such as Netgear’s Nighthawk to take advantage, which Telstra plans to make available this year as well.
Ericsson Australia managing director Emilio Romeo said 2Gbps LTE technology would be an enabler for early deployment of 5G when Telstra goes live with 5G at some point next year.
“We are working with two consistent innovators, Telstra and Qualcomm Technologies, to deliver this world-leading capability in Australia and building greater alignment in the ecosystem for leading operators like Telstra, and device manufacturers to plan for these enhanced world-leading speeds.”
Telstra plans to launch 2Gbps-enabled products early next year in select areas, and will start deploying the technology across its network later this year.
