Just in time for the launch of the new iPhone 5s and 5c, Optus has begun rolling out its second 4G network in Sydney, Melbourne, Brisbane and Adelaide. The second network is based on ‘time division’ technology (TD-LTE) and is the first of its kind in Australia. The current networks operated by Vodafone, Telstra and Optus in Australia are based on ‘frequency division’ technology (FD-LTE) and have become overcrowded with the uptake in 4G devices in recent years. There is expected to be an explosion in the number of 4G users in the coming months as iPhone users upgrade to the 4G enabled 5s and 5c smartphones.
Optus is a step ahead of its competitors with the introduction of the TD-LTE network as the spectrum which the network operates on is currently unpopulated, meaning that Optus can bounce consumers whose devices are TD-LTE enabled between networks, depending on signal strength and capacity. In a crowded space such as the MCG where 4G networks currently come to a standstill during breaks of play, the introduction of the TD-LTE service could provide Optus customers with uninterrupted service and a distinct advantage in the telecommunication industry.
