Australia’s wired National Broadband Network may promise high internet speeds, but trials from two of our biggest telcos suggest wireless may deliver super high speeds before the cable has finished rolling out.

There’s no doubt we’re seeing plenty of news from mobile makers this week, what with Mobile World Congress on over in Spain, but there’s more going on, with word that Australia could see internet speeds hitting past the 1Gbps mark this year.

To put that into perspective, currently most ADSL2+ subscribers in Australia pull down a maximum of around 8 to 15Mbps, which translates roughly into between 1 and 2MB per second for downloads. Over in the world of 4G, Australians range from access speeds of between 60Mbps and 200Mbps, which in turn translates to between 7MB and 25MB per second.

Not too shabby, sure, but when the next generation of 4G LTE arrives — a technology many are referring to as “LTE Advanced” or “4.5G” — we’ll see speeds of around 1Gbps, which translates to around 128MB a second.

If that doesn’t just about blow your eyelids off, we’re not sure what will, and the good news is that this high-speed wireless technology isn’t far off at all, with both Optus and Telstra talking it up in the past week.

Optus, for instance, sent word first, telling GadgetGuy that a test conducted with Huawei achieved speeds as high as 1.41Gbps (180MB per second) when tested in at an Optus test site in Newcastle.

“This field trial in Newcastle is a first and important milestone as a direct result of our local investments in R&D here in Australia, said James Zhao, CEO of Huawei Australia.

“This joint trial represents a significant advance toward fulfilling Huawei’s & Optus’ commitment to developing 4.5G technology in Australia.”
