Telstra has switched on its first 4G LTE base stations in Sydney, Perth, Melbourne and Brisbane.
It also marks the first time 4G data has been sent over the Telstra network beyond the scope of field tests.
In February, the telco announced it was deploying a 4G network using LTE technology from Ericsson expected to be completed by the end of the year. It has partnered with Sierra Wireless to develop dual mode mobile broadband devices.
Dual mode LTE/HSPA+ mobile handsets will be sold by the telco once the 4G network is fully operational.
With the majority of its customers on the NextG network, Telstra was able to re-farm the 1800MHz spectrum that was previously used for 2G mobile services.
“Our customers benefit through having access to more than 2.1 square kilometres of coverage across Australia, and the fastest upload and download speeds with our HSPA+ network,” Telstra Networks and access technologies executive director, Mike Wright, said in a statement.
“We are maintaining this benefit by moving to deploy the first mobile 4G network in Australia.
Vodafone has already initiated 4G deployment through a $1 billion network makeover by building new and upgrading old base stations with Huawei TD-LTE equipment.
Optus has also flagged plans to rollout a 4G LTE network.
