news Optus and Huawei late last week said a live trial of 4.5G technology has produced mobile download speeds of 1.41Gbps.
The successful trial of specific sets of 4.5G technologies, also known as LTE-Advanced Pro, involved a cabled scenario conducted at Optus’ Gigasite in Newcastle, north of Sydney.
Using a combination of carrier aggregation, higher level modulation and 4X4 MIMO, the tests achieved a peak download speed of 1.23Gbps over the air in live network conditions.
Specifically, the trial in aggregated 100MHz (using five 20MHz carriers) of Optus’ unique network frequency bands, and also utilised 4x4MIMO and 256QAM technologies to enable higher peak rates.
The firms added that the advances bring theoretical maximum speeds as high as 1.43 Gbps
“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,” said Dennis Wong, Acting Managing Director at Optus Networks.
The trial is a result of a continued partnership between Optus and Huawei that began with the announcement of the world first Gigasite 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,” said James Zhao, CEO of Huawei Australia.
The continued work on 4.5G, evolving towards 5G technology leverages on a memorandum of understanding (MoU) on joint R&D that Optus’ parent firm Singtel signed with Huawei in 2014.
5G will provide the infrastructure to support a networked society for a multitude of devices and applications. 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.”
