A couple of years ago, we wrote about how Optus had set up 4G testing centres to experiment with network performance and throughput. One recent test was particularly impressive, involving a total of 89 devices and generating a total throughput of 2.3 gigabits per second.
Optus has two test 'gigasites' located in St Mary's in Sydney's west and Lambton near Newcastle. It uses the sites to assess how new spectrum will perform.
To achieve the total site throughput of 2.3Gbps, Optus used "16 test drive vehicles, 21 engineers, 58 devices (smartphones and dongles) and 31 laptops".
Sadly, that doesn't mean any of us will be enjoying 2.3Gbps performance any time soon -- or even the maximum result of 165Mbps achieved by a single device. But it does suggest we haven't maxed out the potential of 4G yet.
