VHA said the new equipment will improve its existing network performance but has yet to decide when to officially switch on its 4G LTE network.

By June, there was still no word from Optus regarding solid plans for a 4G network though the telco did strike a "multimillion dollar" deal with Nokia Siemens to provide LTE compatible packet core technology.

That month NBN Co appointed Ericsson to deploy a 4G LTE fixed-wireless network as part of the National Broadband Network (NBN).

The NBN plan is to deliver broadband through fibre for 93 per cent of Australians. The remainder, mainly in rural and remote locations, will be serviced by fixed-wireless or satellite.

With the LTE network, NBN Co is looking to provide maximum download speeds of up 12Mbps although the company has later said it will attempt to ramp up the speeds. Theoretically, LTE is capable of faster downloading and uploading speeds but wireless is still a shared medium. NBN Co will only explore the possibility of boosting speeds if it is able to do so for everybody covered by the 4G network.
