Optus Launches TD-LTE Network in Major Cities
Australia's Optus has switched on its TD-LTE network, which will compliment its existing FDD based LTE network.
Optus' TD-LTE network operates on the 2300 MHz spectrum band, while their current 4G network runs off the 1800 MHz spectrum band, using FD-LTE.
Optus turned on its "4G Plus" branded service in Melbourne, Sydney, Brisbane and Adelaide to complement its existing 4G network. The TD-LTE network is being progressively rolled out across Australia's major metropolitan centres alongside existing 4G FD-LTE network.
David Epstein, Vice President Regulatory and Corporate Affairs at Optus said, "Australians can now experience life in the 4G fast lane with the Optus 4G Plus network. We're effectively adding more lanes to the Optus 4G super highway, letting more people use our 4G network at the same time.
"That typically means a smoother ride with a better mobile internet experience, both on 4G Plus and in the other lanes too. More lanes on the highway can help ease congestion for data hungry consumers," Mr Epstein said.
Samsung, LG and Apple have recently announced 4G Plus compatible smartphones.
The Optus 4G mobile broadband dongle and WiFi modem are currently in stores and are both 4G Plus ready too. They are also backward compatible with Optus' 3G network.
Samsung's Galaxy S4 Mini and the new version of the Galaxy S4 are dual mode, and will switch between the two 4G network bands.
"These new smartphones will open up access to significantly more 4G capacity, allowing Optus customers to do more on their phones in more places," David Epstein added.
