I don't know how many times this needs repeating before it sinks in, but you are talking about the "marketing term 4G" as it is used in North America.
In the countries complaining, "4G" always refers to LTE or WiMax, while HSPA+ etc. are still called "3G". While it may make no more technical sense than the US usage, that is how regulators and carriers use the term.
As I understand it, LTE may not have an immediate speed advantage over HSPA+ etc. but it does have potential coverage and spectrum usage advantages - so having LTE support would be good future-proofing, as LTE rolls out in Europe over the next few years (not everybody in Europe can get HSPA+ and future expansion may well focus on LTE).
No, no and no. Really. If you buy a new iPad and KNOW about the different tech that is used in wireless transmissions worldwide, or in other words, if you work in the industry, preferably as a tech guy, then you KNOW what the new iPad can and can not do. You belong to the chosen few, that see some light in a huge room of darkness.
However, if you buy the new iPad because you want a wireless conected device that works as fast as possible in any given part of the world and Apple tells you, that the new iPad can do just that, you are also in luck because that is exactly what it does.
I do not know anybody outside my work (I do work in this field) that is even remotly interested how you call the tech, 3G is slower then 4G, thats normally the knowledge thats prevailing.
Now, the new iPad is faster then the iPad2. Heck, its faster then ANY tablet out there. The speed difference between my iPad2 and the new iPad here in Barcelona is staggering, getting an app from the store now takes seconds, if that, with 35Mbit/s and more downloads, a far cry from the lucky 5Mbit/s you could hit with the iPad2.
There is no LTE involved. And please, since when do you buy a electronic gadget with future proofing in mind? Hello? LTE is, if at all, coming here in 2014 and even then in selected test areas, who cares about that today? Nobody could buy anything anymore because they might change the standard in the future or make existing ones better. The existing "3G" network here that gives you up to 42Mbit/s is being worked on to go up to 128Mbit/s, even 156Mbit/s soon, soon meaning within the next few years. Then I'm stuck with my then 3 year old
iPad that can "only" reach 42Mbit/s. Should I not buy it because of that?
If the incompatability of the new iPad to existing or future (in Britains case) LTE networks is the dealbreaker, there is a very simple solution. DO NOT BUY IT. You KNOW its not going to work, its writen on the product, its said on the website, the salesperson tells you and your provider refuses to sell you a contract with it, so why buy it anyway? Simply to complain?
