While the roll-out of the NBN (National Broadband Network) continues slowly, Telstra has just ran a test of it’s future 5G network with two mobile phones and achieved download speeds upwards of 20Gbps. For the record, that is almost 200 times faster than the fastest 100Mbps speeds on the NBN.
Of course, there are variables which will be involved once the network launches in 2020, and 5Gbps speeds are a theoretical maximum which will vary depending on network congestion and of course wireless networks are more prone to drop outs than fixed connections, but it does show how that by the time the NBN is finally completed, it will already be obsolete.
