sorry
I think you got the wrong info.
LTE can theoretically have peak download rates up to 300Mbits. Look at the reviews, test shows they have actual speeds faster than any 3G devices already. (using speedtest.net)
3G, or 3.5G found in the iPhone 4S can only go up to a max of 14.4Mbits if I remembered correctly.
I would care because theoretically speaking, LTE is on par with wifi speeds.
And you're wrong. LTE in the US already have speeds surpassing Hong Kong. Again, check speedtest.net results.
I do not dispute theoretical results. I talk abaut actual results. A test in a lab got nothing to do with a network in the wild.
The new ipad has a LTE chip that THEORETCALLY can manage up to 72Mbits. There are reports that the Verizon version (not sold outside the US) got peaks of 20 Mbits and ATT iPads 14Mbits. The average however is closer around 12 Mbits on Verizon and 7Mbits on ATT. LTE is a shared medium, so if you have more people in a cell, speeds go down.
Now, until now LTE is not really being used, simply because there are not enougch mashines yet. That will dramatically change now with the new iPad, bringing speeds further down.
The new iPad can use HDSPA up to 42Gbits in traditional networks, saving battery and reaching real life speeds of 30-35Mbits. Now, that is far better then LTE und real, not theoretical numbers.
Theoretically HDSPA goes to 168Mbs but nobody would calculate with that, at least not for now.
So, I do not have my numbers wrong, I actually use these systems, until now with a USB stick in a notebook, soon with a new iPad. So I know the available speeds and what I can use in practice is what I'm concerned about, not theoretical speeds.
Btw, wifi is the slowest of all. Again, theoretically you get 54Mbits out of wifi, but what is it conected to? That is the speed you have to see. If I run of a 10 Mbits ADSL line or a 6Mbits congested cable modem, the fastest wifi is not going to help.
