I think I finally understand why the carriers are jumping the gun and calling LTE "4G." (Aside from the fact that marketing types are always happy to jump the gun.) It's because they want to hide the fact that the real 4G spec will combine voice and data. They don't want their subscribers to know that.
Why not? Because right now you pay for two different plans. The voice plan and the data plan. And the carriers want to keep it that way. I'm sure their beancounters have run the numbers and yes sir, separate prices for voice minutes and data bytes increase their profits.
The trouble with the dual-pricing scheme is that true 4G will combine voice and data into one single stream of data packets. It's going to be an all-IP (internet protocol) packet-switched future. And if customers learn that it's all just data, they'll ask "Why am I paying twice for the same technology?" And the carriers won't have a good answer, other than "Because we can charge you more for it that way."
LTE still requires two separate connections: one for voice, and another for data. Just like GSM and CDMA do now. So continuing with the voice/data dual-pricing scheme could more or less be justified. But LTE Advanced, which looks like it could be adopted as the 4G spec, combines voice and data into a single stream of internet packets. It will be VoIP done by the carriers themselves, and won't provide a technological excuse for the dual-pricing scheme any more.
So by 2012, when LTE Advanced starts to roll out, the carriers might start trying to differentiate their terminology. Just to make it sound like they are each using unique technology. They will try to hide the fact that their networks will all be using the same generic internet packets for everything. Instead of them all calling it "the real 4G," or "LTE Advanced," one carrier will call it "5G." Another will call it "Advanced 4G+." You get the idea.
Of course, maybe customers are comfortable with paying separately for voice and data and they won't mind continuing to do it. Talking and browsing are very different activities after all. And really, how many of us actually know the difference between LTE and LTE Advanced?
