Verizon's LTE 4G here in the states is fantastic. I'm lucky enough to live only about an hour away from the nearest 4G location in my state, so I can say that with all honesty. But of course, like anything else, it can get a whole heck of a lot better.
So Ericsson, a worldwide company delivering mobile networking solutions, decided it was just the right time to get us hungry for LTE Advanced. This advanced version of LTE truly is, with speeds up to 10 times faster than those of current LTE technology. That means LTE Advanced can reach a theoretical speed of over 900MB/s. Wow! I'm stuck here with 1.5Mb/s for my home internet and they're reaching that kind of speed over the air!
It also provides for less network congestion, due to the way it reaches those insane speeds. Basically, it uses different frequencies of the spectrum together to create larger "pipes" through which the data travels; that is, instead of a two-lane freeway, you've got a 6-laner.
You can expect to see LTE Advanced technology roll out sometime in 2013.[SlashGear]
