LTE or "Long Term Evolution" is the standard that most of the world takes for granted as 4G, but its reign at the top of the wireless tables is set to be eclipsed by its successor – LTE-A, with the A standing for "Advanced."

4G networks often deliver speeds several megabits faster than many ADSL2+ networks, some of which struggle to pump out even 6 Mbps speeds, even though theyre rated at a theoretical maximum of around 20 Mbps – something youll only see if youre quite close to your local telephone exchange.

Meanwhile, an iPhone 5s Im using on Telstras existing 4G network just pumped out speeds of 13.18 Mbps (after boosting straight past 20 Mbps before slowing back down), with an upload speed of 14.06 Mbps, after quick testing with the Ookla Speedtest.net app.
