Australia's 4G LTE networks are increasingly growing more complex, with Telstra announcing that it is currently testing its own LTE-Advanced (LTE-A) network.
Similar to what SK Telecom has set up in Seoul, South Korea, Telstra is currently testing its LTE- Advanced Carrier Aggregation network using the 900MHz and 1800MHz spectrum bands.
All of the 4G
The LTE 4G field in Australia is getting a little bit crowded, with Vodafone and Telstra duking it out over being the first to launch Australia's first Cat 4 device.
Optus, on the other hand, is still developing its own TD-LTE network and will be the first to offer dual-mode Samsung Galaxy S4 and Galaxy Mini variants. These dual mode devices will be able to switch between Optus' TD-LTE network and the more common FD-LTE network.
Telstra said that it is also planning on further developing its LTE-A network in the future once it gains access to the 700MHz spectrum in 2015. It will combine the 1800MHz band and the 700MHz, which could theoretically push download speeds to 300Mbps.
