Optus and Huawei have announced attaining an aggregated cell throughput speed of 665Mbps shared across 16 devices using Massive Multiple-Input Multiple-Output (MIMO) technology.
The trial, announced at Mobile World Congress (MWC) in Barcelona on Wednesday, was conducted on Sunday across a single frequency channel of 20MHz on the 2300MHz band using beam-forming technology.
"Massive MIMO is an important technology enabler and lays the foundation for the upcoming 5G," Optus Networks managing director Dennis Wong said."Massive MIMO is an important step along the journey to 5G, as it allows us to immediately increase cell site capacity and spectrum efficiency. For customers, this means that their experience will be of consistently high standard even in high-usage situations."
Sharing the speeds across 16 devices was a trial of how users will consume multimedia content simultaneously across Optus' network, with the telecommunications operator clocking a 75 percent increase year on year in data consumption. Huawei's Massive MIMO active antenna unit (AAU) solution -- which won the best mobile infrastructure award at MWC -- was used for the trial, which has 16 beam-forming streams in a 128T128R configuration.
