Australia's Optus has commenced the rollout of VoLTE technology to Australia's major capital cities.
The Singtel subsidiary revealed that its initial rollout will concentrate on the central business district metro areas of Sydney, Melbourne, Brisbane, Adelaide, Perth and Canberra.
Optus will initially offer VoLTE over Samsung's flagship Galaxy S7 and S7 Edge smartphones.
Optus Networks acting managing director Dennis Wong said the company plans to “continue to add capability to other devices and remains focused on expanding our VoLTE footprint to further locations, particularly in regional Australia.”
“We’ve been testing and tweaking VoLTE for the best customer experience and we’re excited Optus customers will start to see the benefits of this technology on our 4G Plus network.”
Last year the operator launched the first commercial 3x LTE-A carrier aggregation network combining one FDD carrier with two TDD blocks. The network combines 1800-MHz and 2300-MHz frequency bands.
Optus is Australia's second largest operator after incumbent Telstra, offering both fixed and mobile services as well as satellite and other services.
