Optus And Huawei Are Trialing 4.5G

On 17 February Optus and Huawei conducted a live trial of 4.5G technology at Optus’ Gigasite in Newcastle. The trial resulted in download speeds of 1.41 Gbps, with "theoretical maximum speeds reaching 1.43Gbps," Optus has announced in a statement.

"The combination of Carrier Aggregation, Higher Level Modulation, and 4X4 MIMO achieved a peak download speed of 1.23Gbps over the air in live network conditions," the statement reads.

Dennis Wong, Optus Networks acting Managing Director said "We continue to utilise our network and spectrum assets to test our network of the future and prepare for 5G. By 2020, 5G will be here and we are committed to identify ways to prepare our network to support this new technology and further improve customer experience."

Optus and Huawei have been collaborating on research since the first Gigasite opened in 2013.

"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. This joint trial represents a significant advance toward fulfilling Huawei's and Optus' commitment to developing 4.5G technology in Australia," James Zhao, Huawei Australia CEO said.

David Wang, President Huawei Wireless Networks said "4.5G and related technologies are the future of our increasingly digitalized world. Huawei together with Optus will strive to foster an open and a better connected Australia."

The continued work on 4.5G, evolving towards 5G technology leverages on the Memorandum of Understanding (MoU) on joint research and development that parent telco Singtel signed with Huawei in 2014.

"5G will provide the infrastructure to support a networked society for a multitude of devices and applications," Optus states. "Apart from advanced wireless techniques, another key aspect is machine type communications to support the Internet of Things."

Tay Soo Meng, Singtel Group Chief Technology Officer said, "As we work towards 5G we expect significant demand for cost-effective connection to a multitude of sensors and devices, and it is important that operators deliver new capabilities to enable the new connected ecosystem to support the growth and innovation of M2M services.

Singtel continues to pursue leading technologies and is in close collaboration with industry players like Huawei as part of our 5G partnership programs."



    So that would be 40% faster than the NBN and at east five years sooner for me, too. So why did the government waste tens of billions on the NBN again?

      There was a "fun" story on one of the news sites about a government employee being given $100k to buy IT equipment for his department and he ended up spending $40M...

      Amazing, it took only 16 minutes.

      Since this point has been covered endlessly. either you don't read the comments & just post your own, or you're determined to ignore it all and keep trolling people.

      But for anyone else that's new here:

      * Wireless is shared between everyone in the cell, so dividing it between a few hundred homes would make it laughably slow. It couldn't even cope with today's broadband needs, let alone tomorrow's.

      * Higher speeds need higher frequencies, which don't penetrate walls, trees, weather etc so well, so in the majority of usage cases it has to fall back to lower frequencies & speeds.

      * Wireless can't be upgraded much without going to even higher frequencies or devoting more & more of the spectrum to each user, which make the first two points even worse.

      There are many more reasons, but those are more than enough to kill wireless as a substitute for fixed-line broadband.

      Mobile networks do not have the bandwidth to handle internet connections dipstick. Networking 101

    Sure the comparisons to the sucky NBN will be made but still, this is pretty incredible. This means that no matter how you connect, it has the ability of so blistering fast regardless of method of connection. Yes that 1.whatever gigabit/s is in an ideal situation with one device...thing is, 4G is giving me 50 to 100mbit/s right now. I don't think it's that unfeasible to think that in the next few years, you'll be downloading at 500mbit/s at all. I just get excited at the thought. Its cool stuff.

      Thing is, the main new feature in LTE-A Release 13 that allows speed numbers like these is that it can aggregate more channels together (5 x 20MHz in this test), using more of the available spectrum. This can allow some crazy-sounding speeds - but only if no-one else wants to use those channels too. In the real world, with more than one user per cell tower, those big speeds get divided among everyone. There's only so much spectrum to go round, so it has to be shared - and mobile data is only getting more in demand.

      That's really the main issue with wireless. We're getting close to the theoretical maximum speed that can be squeezed out of a given frequency, and future technology is unlikely to change that much, so the only way to improve is to just use more channels. We can't keep giving higher speeds to everyone without finding more spectrum from somewhere. Freeing up the old analogue TV spectrum helped for now, but don't expect to get 500Mbps anytime soon, at least not unless you've got the cell tower to yourself.

    It would be better if Optus spent its time getting 4G working as well as we were promised.
